User Manual DEV 1953

Environmental Conditions The device is designed for indoor use and for an ambient temperature range.

Mechanical Integration It is not permitted to fix the chassis on the rack mount flanges, only. Balanced weight distribution of the chassis has to be ensured by placing it on a solid surface or by using rack rails. Sufficient airflow through the chassis must be ensured to achieve best cooling results. Do not block or obstruct the airflow through the chassis at the front and at the rear side, e.g. by placing large components close to the rear side.

Grounding, AC Connection, Cables To minimize shock hazard the device must be connected to an electrical ground via a ground wire, please refer to chapter 4.2.2. For the AC connection, the device must be connected to the AC power supply mains through two power cables with three conductors and with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective ground conductor will cause a potential shock hazard that might cause personal injury. Risk of electrical shock and energy hazard: Disconnecting a single power supply line only does not interrupt the AC supply (with Option 14: DC supply) of the device. To isolate the device completely, disconnect both power supply lines. Do not connect the device to AC mains supply exceeding the specifications for input voltage and frequency. The recommended AC cables to be applied are standard high temperature power cables with type IEC 60320-C13 appliance plug appropriately rated to the conditions of the country where the device is operated. With applied Option 14, the device is supplied with DC voltage instead of AC mains. In this case, do not connect the device to DC mains supply exceeding the specifications for input voltage. For the DC supply wiring use cables with an appropriate wire size. The pin assignment of the DC supply connector is stated in chapter 7.

Laser Safety (applies if equipped with Optical Switch Modules DEV 7462, DEV 7463)

 Safety of Laser Products

DEV Systemtechnik recommends following the governing standard of the country where the product is operated to assure regulatory compliance and to provide the necessary safety programs to protect the operators and other persons who get in contact with the product.

 It is recommended to power down the product while working on the optical

fiber wiring.

 The optical modules installed in the product operate with light at a non-visible

wavelength. Highest caution has to be taken, since the modules may carry laser light that is capable to harm the human eye! If no optical fiber is (to be) connected to an optical module, the optical connector(s) have to be equipped with the appropriate protection cover(s).

 Direct exposure to the beam is to be avoided, i.e. do not look into

unterminated optical ports or at fibers that connect to unknown sources.

3 Product Description

With the DEV 1953, DEV Systemtechnik has developed a modular design principle for a universal switch chassis. A variety of different switch modules is available that can be installed easily in the 16 slots of the device. A selection of passive splitter modules and of distribution amplifier modules for ASI/SDI signals is available as well. Please refer to chapter 3.2 for the description of the single modules.

A device panel (chapter 3.1.1) permits the monitoring and the local control of the DEV 1953. Some other methods for the control and for the surveillance of the device are provided (chapter 3.1.2). The application of sensing switch modules and of digital signal switch modules enables additional autonomous switching capabilities of the DEV 1953 (chapter 3.1.3) as well as the application of the TRAC (stands for "Trap Receiver Action Controller") option (chapter 3.1.5).

3.1 Features and Options

3.1.1 Device Panel

Aside from the device panel -which is explained in the following- the product provides the "Reset" push button on the CPU module (please refer to chapter 3.2.24) for restarting the device, and the two LEDs on each power supply module (chapter 3.2.25).

The device panel occupies most of the space at the front side of the chassis:

The mode push button (3) permits the change of the operation mode (chapter 5.1) at the device. By pressing and holding the push button for ~3 seconds the status of the LEDs advances, i.e. always only one of the operation mode LEDs "Remote" (4), "Local" (5), or "Auto" (6) is on. The second functionality of the mode push button is the event acknowledgment: If there are pending and not acknowledged event(s), this is indicated via continuous alternate blinking of all channel LEDs. To acknowledge the event(s) (i.e. to stop the blinking of the LEDs) at the device, the mode push button is to be operated. Thus, three scenarios for the behavior of the mode push button are to be considered:

1. There are no pending and not acknowledged event(s): In this case, the operation mode can be altered as described above.

2. There are pending and not acknowledged event(s) in Local Mode: A short operation of the mode push button acknowledges the event(s) (stops

the blinking of the LEDs). After that, the operation mode can be altered as described above.

Page 11

User Manual DEV 1953

3. Pending and not acknowledged event(s) in Remote Mode (or Auto Mode): A short operation of the mode push button acknowledges the event(s) (stops the blinking of the LEDs) and switches the device to Local Mode. After that, the operation mode can be altered as described above.

Note:

 Usually the type of event causing the event indication via device panel can be

identified via Web Interface or via remote interface, only.

 If event(s) are not acknowledged yet, the alternate blinking of all channel LEDs

is performed synchronously but according to the switching status of the device.

 If an event is not acknowledged and if the event disappears (e.g. a detected

missing AC line is working again), the event indication via device panel will stop automatically (if it is the sole event).

 The event indication via device panel cannot be stopped if no switch (or

distribution amplifier) module is installed or detected within the device.

With the sixteen channel push buttons (indicated by 7 in the figure above) labeled "1"…"16", one of the two (input) ports (primary (input) port "In A" or secondary (input) port "In B") of a switch module can be switched to the common (output) port in Local Mode (!). The (input) port that is currently active is indicated via the related green channel LED. The switching mode push button and the yellow LEDs labeled "Simultaneous" and "Individual" (indicated by 8 in the figure above) are for the Simultaneous/Individual switching mode functionality of the device, which is described in chapter 5.1.4.

To alter the routing of a single switch module via the related channel push button make sure that the device is in Local Mode and that the "Individual" LED is lit. After the operation of the desired channel push button, the LED display will indicate the altered switching position as a receipt. If the "Simultaneous" LED is lit (for the preconditions to activate Simultaneous switching mode please refer to chapter 5.1.4), any of the channel push buttons of a group can be operated to initiate the switching of the switch modules being member of the group.

Note:

 The channel push buttons (7) and the switching mode push button (8) are

enabled in Local Mode, only.

 The related channel push button (7) is not functional (i.e. the LED always

indicates position "In A") if a slot is not equipped with a switch module.

3.1.2 Communication Features

In addition to the device panel there are provided some options for the monitoring and control of the product: The Web Interface (please refer to chapter 5.5) provides features for checking the health status and for changing the setup of the device; it enables full control in terms of switching and in terms of setting up specific parameters. Additionally, the features Time Based Switching and TRAC (if installed), and -for devices with installed sensing switch modules- the recording functionality are accessible.

The implementation of SNMP (Simple Network Management Protocol) via the Ethernet interface is intended to serve as the standard for remote monitoring and control of the device (chapter 5.9).

Page 12

User Manual DEV 1953

In addition, a Communication Protocol Handler (CPH) is implemented which enables the use of one of the following remote protocols with different monitoring and control capabilities:

 Sandar Prosan protocol via serial interface (chapter 5.6);  Leitch protocol via serial interface and via Ethernet interface (chapter 5.7); and  QEC protocol via serial interface and via Ethernet interface (chapter 5.8).

The installation of sensing switch modules and of digital signal switch modules enables the autonomous switching capability (chapter 3.1.3) of the device based on the signal quality. Moreover, the TRAC option (chapter 3.1.5) permits a remote device to control the switching of the DEV 1953. Finally, the digital interface options (chapter 3.1.4) feature basic remote switching functionality permitting the control of the device.

3.1.3 Autonomous Switching and Options

Among the broad choice of other switch modules, the DEV 1953 can be equipped with sensing switch modules and/or with digital signal switch modules. The sensing switch modules (and the digital signal switch modules) are special since they permit the device to switch autonomously (please refer to chapter 5.1.3) based on the RF level information (and on the digital signal quality information, respectively) at both input ports of the module. By default, the DEV 1953 provides autonomous switching capability from the primary to the secondary input port(s). With Option 22, the DEV 1953 is delivered with the main backup swap feature, i.e. the autonomous switching works in both directions instead of switching from the primary to the secondary input port(s), only. With Option 28 the DEV 1953 is delivered with the automatic switch back feature which permits the autonomous switching in both directions as well, but with an adjustable hysteresis (for sensing switch modules) or with an adjustable delay (for digital signal switch modules) when switching back from the secondary to the primary input port(s). The Web Interface enables the adjustment of the RF threshold levels for each input port of a sensing switch module and enables the modification of settings for the automatic switch back option.

3.1.4 Digital Interface Options

As an option (Option 56 for 24 V and Option 57 for 12 V) the product is equipped with a digital interface module (please refer to chapter 3.2.26), e.g. to be connected to a PLC (Programmable Logic Control). With this interface, it is possible to switch up to 16 channels of the device and to obtain switching status information for each channel.

3.1.5 TRAC Option

The DEV 1953 can be equipped with the TRAC (stands for Trap Receiver Action Controller) option (Option 37), which permits the remote controlled switching of the product based on SNMP traps, or based on the availability or on the absence of a remote device (IP Monitoring). For more details, please refer to chapter 5.5.7.3.5.

3.1.6 Other Options

By default, the DEV 1953 is delivered with two redundant wide range AC power supplies that are connected to separate AC lines. Option 14 permits a redundant DC supply of the device supplied by two different lines with -36...-75 V DC input voltage (or with +36...+75 V DC by inverting the polarity).

A single license for the Web Interface (please refer to chapter 5.5) is included in the delivery of the product, additional licenses can be ordered initially via Option 78. Note that it is possible to purchase additional license keys at any time, please contact DEV Systemtechnik.

Next, establish the external Ethernet connection by plugging an Ethernet cable from your network to the "Ethernet" (3) of the CPU module.

If the basic network setup via serial interface is required (please refer to chapter

4.4.2.2), and/or if it is intended to control the device via the serial interface using

Sandar Prosan protocol, Leitch protocol, or QEC protocol, a serial connection between a PC and the serial connector of the CPU module labeled "Com" (2) is to be established. The configuration of the serial interface is described in chapter 4.4.1; please refer to chapter 7 for the pin assignment of the serial connector.

If the device is equipped with a digital interface module (Option 56 or Option 57) and if it is intended to control the DEV 1953 via the digital interface, connect a prepared cable to (8). The pin assignment of the digital interface module connector is stated in chapter 7.

30  Copyright DEV Systemtechnik GmbH 2015-2017

Page 31

User Manual DEV 1953

Finally, connect two power cords to the primary connectors (4 & 5). It is recommended to use two separately fused phases of the available electrical outlets. If the device was ordered with Option 14, the power cables have to be prepared. The matching connectors are part of the delivery; the pin assignment is stated in chapter 7.

Note:

 It is highly recommended to power up the device after the installation of the

modules (chapter 4.2.5) and after the connection of all signal cables (chapters

4.2.3 & 4.2.4).

 The power lines are fused separately; the fuse holders (6 & 7) are located

below the related power inlet (4 & 5). If a fuse has to be exchanged, unplug the device completely and use 2 A T 5*20 mm glass fuses (4 A T 5*20 mm glass fuses for devices with Option 14) for replacement only!

4.2.3 Connection of Optical Signal Cables

Only if the DEV 1953 is equipped with optical switch modules DEV 7462 and/or DEV 7463, optical fibers have to be connected to the installed optical modules.

Please refer to the laser safety warnings stated in chapter 2.3! If applicable, apply strain relieves to the optical fibers which are to be connected to

the installed optical modules in a way, that the connectors of the optical modules are not stressed mechanically.

Sequentially, remove each optical connector protection cover at the device, and plug in and tighten the corresponding connector from the optical fiber bundle(s).

Note:

 The optical modules are available with different optical connector types, i.e.

FC/APC, E2000 HRL, or SC/APC. Make sure, that the matching connectors are installed in the application.

4.2.4 Connection of RF Signal Cables

Apply strain relieves to the external RF signal cables which are to be connected in a way, that the connectors of the device are not stressed mechanically.

When connecting RF cables to the installed modules, each connector providing a thread is to be tightened with a torque wrench. For 75 Ohm F connectors the applied torque should not exceed 4.5 Nm (39.8 lbf-in). In case of 50 Ohm SMA connectors a torque wrench adjusted to 1 Nm (8.85 lbf-in) is to be used. If a module is equipped with BNC connectors, make sure that the bayonet of each RF connection is locked.

Note:

 For 75 Ohm RF connectors, either female 75 Ohm BNC connectors or female

precision F connectors are applied. Make sure, that the applied connectors are male 75 Ohm BNC connectors or male precision F connectors (with thin inner conductor).

 Each unused output port of a passive splitter module or of a distribution

amplifier module is to be terminated with an appropriate load (i.e. 50 Ohm SMA (m), 75 Ohm F (m), or 75 Ohm BNC (m)) to achieve best amplitude frequency response.

 If all cables are connected, the device can be powered up.

4.2.5 Installation and Exchange of Modules

The product is usually delivered with the ordered modules, which are already installed. Therefore, you may proceed in reading the next chapter. In case that a module has to be exchanged or if the DEV 1953 is to be upgraded with additional module(s), the following instructions are to be noticed.

Note:

 "Modules" which are assembled using regular Torx screws are to be treated by

DEV Systemtechnik, only.

 Though the exchangeable modules are hot pluggable, it is recommended to

power down the device for exchange operations to avoid short circuits and for safety reasons. There may be situations where a longer lasting interruption of the signal transmission is not permitted, so -for instance- an exchange of a power supply module has to be performed while the device is powered up. In this situation, the operations as described below can be performed without problems, but have to be carried out with the utmost caution.

 After removing, adding, or exchanging a switch module (or a distribution

amplifier module) while the device is powered up, the DEV 1953 has to be restarted to update the CPU module regarding the applied changes. This can be done without interruption of the signal transmission.

 If exchanging or installing optical modules, please especially refer to the

warnings regarding laser safety stated in chapter 2.3.

 If the CPU module is to be exchanged, the Micro-SD card of the old CPU module

is to be inserted in the exchange CPU module.

 The CPU module provides a push down lever to simplify the extraction of the

module (please refer to chapter 3.2.24).

 Note that in rare cases the insertion of a module may cause an automatic

device reset.

 The device is to be equipped with at least one switch module (or one

distribution amplifier module). If not a single switch (or distribution amplifier) module is installed or detected, the device signalizes this by a permanent event indication (i.e. the channel LEDs at the device panel are blinking and this cannot be stopped).

Removal of a module: Any cable attached to the front side of the module is to be disconnected it in the

first step. For the removal unscrew the (all) knurled head screw(s) of the module (or of the blind plate) before gently pulling out the module completely (or before taking off the blind plate).

Installation of a module: In the first step, plug in the module by inserting it into the two card guides of the

desired slot and by gently pushing the module into the chassis that it levels with the rear side of the device. Screw in the (all) knurled head screw(s) of the module, next. Finally, (re-)connect the corresponding cables to the module.

4.2.5.1 Exchange of the Micro-SD Card and Backup of the Configuration Data

If the Micro-SD card of the device needs to be exchanged, the following steps are to be performed in order to transfer the configuration of the device to the new Micro-SD card. For an external backup of the device configuration data, only the first two steps need to be executed:

1. Using the data backup functionality (please refer to chapter 5.5.7.4.2) of the Web Interface to perform a backup of the "Module Data" and of the "Device Data" (to different slots/lines!).

2. Use the button of the data backup functionality for the external storage of both backup sets ("Module Data" and "Device Data").

3. Considering the instructions of chapter 4.2.5 to remove the CPU module, exchange the Micro-SD card, install the CPU module, power up the device, and login to the Web Interface (chapter 5.5.1) again using the factory network settings (chapter 4.3.3, considering chapter 4.4.2.1).

4. Using the button of the data backup functionality to import the externally stored "Module Data" backup set and "Device Data" backup set (to different slots/lines!).

5. To apply the imported backup sets to the device, the button is to be used now for the imported "Module Data" and for the imported "Device Data". Check the data categories/settings that are to be restored (usually all of them)

before operating the button.

Note:

 Since the device provides numerous parameters and settings it is generally

recommended to perform the first two steps described above after the installation of the device is completed, after major changes on the settings, and before updating the device firmware.

4.2.6 Reset of the Device and the Restore of Factory Defaults

During power-up or after a restart the CPU module performs a health check and scans the assemblies of the device, e.g. to detect whether a module is installed in a slot or not. If there is a module installed, the settings for this slot are transferred to the module. This implies that a reset is necessary only if changes on the modules population of the device were performed or if there were applied elementary changes, e.g. restoring the factory defaults via the Web Interface.

A device reset can be performed in three different ways:

1. Reset via the "Reset" push button (please refer to chapter 3.2.24): Press and hold (e.g. by using a ballpoint pen) the "Reset" push button of the CPU module for approximately three seconds.

2. Reset via the serial interface when terminating the configuration program (chapter 4.4.2.2.1).

3. Reset via Web Interface (chapter 5.5.7.4.3).

Note:

 It takes about 60 seconds after a device reset or after a power cycle that the

device is completely accessible again via the device panel, via the (optional) digital interface, via the serial interface, via Web Interface, and via the different remote protocols, e.g. via SNMP.

 Copyright DEV Systemtechnik GmbH 2015-2017 33

Page 34

User Manual DEV 1953

 If the Web Interface does not react after a restart, then the ARP (Address Reso-

lution Protocol) cache of your computer may have to be cleared by opening a command window and by typing: "arp –d<CR>" (<CR> stands for hitting the "Enter" or "" key on the keyboard).

 If –for any reason– neither a reset nor a power cycle of the device restores all

functionality, a reset to factory defaults is to be considered:

Usually, the factory settings (chapter 4.3) can be restored via Web Interface (chapter 5.5.7.4.1). If the device is not accessible via Web Interface, the factory settings can be applied in the following manner:

 Press and hold the "Reset" push button of the CPU module e.g. by using a

ballpoint pen.

 The yellow LED on the "Ethernet" connector of the CPU module starts to blink

after ~20…50 seconds, indicating that the "Reset" button can be released. Now a reset follows resulting in a device with restored factory settings.

4.3 Device Factory Settings

The product is delivered with factory settings as described in the following. It is possible to restore these settings, please refer to chapter 4.2.6.

4.3.1 Factory Settings for Sensing Switch Modules

All sensing switch modules provide RF level monitoring functionality. I.e. for both input ports, the aggregated signal power level of the RF signal is measured and compared with an RF threshold level. If the RF level is below the RF threshold level, an event is triggered which is indicated e.g. via Web Interface. The factory setting for the RF threshold level for each input port of a sensing switch module depends on the lower limit of the applied sensing switch module:

RF threshold level: (20 dB above lower limit) For example, if the lower limit is -50 dBm, the factory setting for the RF threshold

level is -30 dBm. The RF threshold level can be adjusted for each input port via the Web Interface (please refer to chapter 5.5.4.2) or via SNMP (chapter 5.9.4.3.9.6) in a range which depends on the applied sensing switch module. Note that if an exchange module is inserted in a slot of the DEV 1953, the new module inherits the stored settings of this slot (after a device reset).

4.3.2 Factory Communication Protocol Configuration

The factory setting for the Communication Protocol Handler (CPH) is the Leitch protocol, i.e. the serial interface configuration are the standard serial interface configuration settings, please refer to chapter 4.4.1.1. Chapter 5.5.7.2.3 describes the change of the protocol assignment.

4.3.3 Factory Network Settings

The factory network settings of the device are:

IP-Address: 192.168.0.11 Netmask: 255.255.255.0 Gateway: 192.168.0.99

For changing the network setup, please refer to chapters 4.4.2.2 & 5.5.7.2.1.

4.3.4 Factory SNMP Settings

The factory SNMP settings are configured as follows:

Read Community: public Write Community: private

Local/Remote changeable via SNMP:

Additionally, the default community for all four Trap Destination IP Addresses is set to public and all configurable traps are disabled. If an address is defined without explicit port assignment, the standard SNMP trap port 162 is assigned implicitly. For changing the SNMP setup, please refer to chapter 5.5.7.2.2. There are software factory defaults for some SNMP objects, please refer to the corresponding chapters:

 .application.controlMode chapter 5.9.4.3.1  .application.portTable.portEntry.poEnable chapter 5.9.4.3.9.2  .application.portTable.portEntry.poRfLimit chapter 5.9.4.3.9.6  .surveillance.trapEnableMask chapter 5.9.4.4.1  .surveillance.errorEnableMask chapter 5.9.4.4.2

4.3.5 Factory Sandar Prosan Protocol Settings

By default, the setting "Echo in Local Mode" is disabled. I.e. if the device is in Local Mode, it does not respond to any Sandar Prosan command; please refer to chapter

5.6.1. This setting can be changed by issuing the Sandar Prosan command PME1

(chapter 5.6.3.7) or via Web Interface (chapter 5.5.7.2.3).

4.3.6 Factory Leitch Protocol Settings

By default, the setting "Echo in Local Mode" is disabled. I.e. in Local Mode, the device responds with the Leitch Error Message to any valid Leitch command. Furthermore the setting "Individual Switch Level Assignment" is enabled by default, please refer to chapter 5.7.1. Both settings can be changed via Web Interface (chapter 5.5.7.2.3).

4.3.7 Factory QEC Protocol Settings

The factory setting for the QEC serial address is 0x11 (decimal: 17). Chapter 5.5.7.2.3 describes the change of this setting.

4.4 Communication Interface Configuration

Aside of the optional digital interface module that permits the switching via dry contacts, two hardware interfaces are provided at the CPU module for the communication with the device: a serial interface and an Ethernet interface. The serial interface can be used for the basic network setup and for the operation via Sandar Prosan protocol, or via Leitch protocol, or via QEC protocol. The Ethernet interface is used for the operation via Web Interface, via SNMP, and via Leitch protocol or via QEC protocol through Telnet.

4.4.1 Serial Interface

The Sub-D 9 pos female connector labeled "Com" for the standard (3 wire) RS 232 interface is located at the CPU module; the pin assignment is stated in chapter 7. The serial interface of the device supports different remote protocols defined by the CPH configuration. The default protocol assignment of the serial interface is

 Copyright DEV Systemtechnik GmbH 2015-2017 35

Page 36

User Manual DEV 1953

subject of chapter 4.3.2. The protocol assignment can be changed via Web Interface (chapter 5.5.7.2.3); there it is possible to deselect any CPH support as well.

4.4.1.1 Standard Serial Interface Configuration

The standard serial interface configuration is applied if the device is configured to support none of the available CPH protocols (i.e. to support the network setup via serial interface, only) or if the device is configured to support the Leitch protocol or the QEC protocol. The standard serial interface configuration is described by the following parameters:

Transmission rate: 9600 Data bits: 8 Parity check: none Start/Stop bit: 1 Handshake: none

4.4.1.2 Sandar Prosan Protocol Serial Interface Configuration

The Sandar Prosan protocol serial interface configuration is applied if the device is configured to support the Sandar Prosan protocol. The Sandar Prosan protocol serial interface configuration is described by the following parameters:

Transmission rate: 9600 Data bits: 7 Parity check: odd Start/Stop bit: 1 Handshake: none

4.4.2 Ethernet Interface

The connector labeled "Ethernet" at the CPU module is an RJ-45 jack for the standard 100Base-TX Ethernet interface; chapter 7 describes the pin assignment.

4.4.2.1 Ethernet Connection

If a standalone device is to be connected to a PC only, the connection can be established via a direct Ethernet cable (or through a local hub/switch) between the Ethernet connector of the device and the Ethernet connector of the PC. The network setup of the PC is to be altered that it is in the same subnet as the device. If it is intended to use the factory network settings, the IP address of the standalone PC is to be set to 192.168.0.x, with x in the range 1…254, except 11, which is the address of the device, e.g. set the IP address of the standalone PC to the default gateway address 192.168.0.99. If the device is to be connected to the local network, make sure to change the network setup as required. Ask your network administrator for the details on network parameters which are to be used. The factory network settings are subject of chapter 4.3.3.

There are two different methods to change the network setup. First, the network setup can be changed via Web Interface (please refer to chapter 5.5.7.2.1). The other method that can be performed is subject of the following chapter.

4.4.2.2 Network Setup via the Serial Interface

Only a few elementary parameters of the network setup can be changed via the serial interface. First, establish a hardware connection between a serial port of a PC (e.g. COM1) and the RS 232 interface of the device (i.e. the connector labeled "Com" at the CPU module) using a straight cable; please refer to chapter 7 for the pin assignment of the serial connector. Next, start a terminal application (e.g. MS Windows HyperTerminal) on the PC.

Note:

 The interface settings of the terminal application have to match the standard

serial interface configuration (chapter 4.4.1.1); otherwise, it is not possible to enter the configuration program as described below.

 The terminal application is to be configured that the "Backspace" or "←" key on

the keyboard works properly in the application, and that it sends a <CR> only (and not a <CR><LF>) when hitting the "Enter" or "" key on the keyboard. If using MS Windows HyperTerminal, select the "Properties" entry from the "File" menu and click on the "Settings" tab. There, select "ANSI" from the Emulation drop down list and then click on the button to uncheck "Send line ends with line feeds" as shown in the following figure:

4.4.2.2.1 Start and Termination of the Configuration Program

If the serial interface is used for the communication via one of the CPH protocols, the access to the configuration program can be established during power-up or after a device reset, only. In this case, the terminal application is to be started and is to be connected (with the standard serial interface configuration settings, please refer to chapter 4.4.1.1) before the boot phase.

While the device is booting press and hold (max. 60 seconds) the keys <Ctrl> and T (i.e. <Ctrl>-T) in parallel on the keyboard until the following message appears:

please release key

After releasing the keys, the following text is displayed:

You have 60 seconds for login... DEV login:

To start the configuration program the login procedure must be accomplished within 60 seconds with the following authentication:

DEV login: config<CR> Password: devConfig<CR>

User Manual DEV 1953

Note:

 <CR> stands for hitting the "Enter" or "" key on the keyboard.  All characters/commands to be entered are case sensitive.  If the serial interface is not assigned to any CPH protocol it is not required to

press <Ctrl>-T during the boot process. I.e. it is always possible to enter the configuration program without any time limits or restrictions regarding the number of login attempts.

 Otherwise (i.e. if a CPH protocol is assigned), if nothing is entered at the

DEV login: prompt, or after the third unsuccessful attempt to login, the CPH

takes over the serial interface which is announced by:

CPH starts now!

After successful authentication, the configuration program is launched. After start and after the finalization of most of the choices the program lists the choices that can be performed:

config ======

1 set IP address (192.168.0.225) 2 set netmask (255.255.0.0) 3 set gateway (192.168.0.99) q quit without saving x save configuration and exit

your choice >

Choices can be executed by typing the character in the first column of each line followed by a <CR>. The second column of each line provides a short description of the choice and the third column displays in parentheses the current setting of the corresponding choice. In the example above, the IP address and the netmask are different from the factory network settings (chapter 4.3.3).

When using the "q" choice the configuration program terminates. If a CPH protocol is assigned, the CPH takes over the serial interface, which is announced by:

CPH starts now!

When using the "x" choice the configuration program saves all changes made and resets the device (i.e. rebooting the device):

your choice > x<CR>

rebooting the device, please wait...

After a device reset it takes a few moments before the serial interface is accessible again as described at the beginning of this chapter. In the following, the available choices are explained:

5 Operation of the Product

After going through the installation steps as described above, the device is ready to use. There are different options for monitoring and control, please refer to chapter

3.1.2. Before the operation via each of these possibilities is explained, the different

device operation modes are described:

5.1 Modes of Operation

Local Mode, Remote Mode, and Auto Mode define the manner how the device is controlled. In addition, Individual switching mode and Simultaneous switching mode define the switching behavior of the device. The operation mode can be changed via the mode push button at the device panel (please refer to chapter 3.1.1), via Web Interface (chapter 5.5.2), via SNMP (chapter 5.9.4.3.1), and via Sandar Prosan protocol (restricted to the change between Remote Mode and Auto Mode and vice versa (chapter 5.6.3.6)).

Note:

 The factory setting for the operation mode is Remote Mode.

Changing the switching mode (chapter 5.1.4) is possible only if the DEV 1953 is equipped with at least two switch modules. In Local Mode the switching mode can be altered via the switching mode push button at the device panel (labeled 8 in the figure of chapter 3.1.1) or via Web Interface (chapter 5.5.4.1). In Remote Mode, the switching mode can be changed via Sandar Prosan protocol (chapter 5.6.3.8) and via SNMP (chapter 5.9.4.3.3).

5.1.1 Local Mode

In Local Mode the device executes commands which are issued via push button actions at the device panel or (also in parallel) via Web Interface. The optional digital interface is disabled in Local Mode as well as the functionality of the different remote protocols (SNMP, Sandar Prosan, Leitch, and QEC) to issue switching commands and to modify the settings of the device. However, the communication to the remote interfaces either is enabled or is capable to be enabled (keyword "Echo in Local Mode", please refer to chapters 5.6.1 & 5.7.1) for status queries. No autonomous switching is performed in Local Mode if the DEV 1953 is equipped with sensing switch modules (and/or digital signal switch modules). Neither Time Based Switching nor TRAC initiated switching is performed in Local Mode, as well.

5.1.2 Remote Mode

The Remote Mode is implemented for operation via the optional digital interface, via SNMP, via Sandar Prosan protocol, via Leitch protocol, or via QEC protocol. In Remote Mode, the status of the device is indicated via the LEDs at the device panel and via Web Interface, but the buttons at the device panel are locked and the control functionality of the Web Interface is disabled. No autonomous switching is performed in Remote Mode if the DEV 1953 is equipped with sensing switch modules (and/or digital signal switch modules). Neither Time Based Switching nor TRAC initiated switching is performed in Remote Mode, as well.

Page 41

User Manual DEV 1953

5.1.3 Auto Mode

The Auto Mode is used for Time Based Switching (please refer to chapter 5.5.7.3.4), or for the optional TRAC functionality (chapter 5.5.7.3.5), or for autonomous switching if the DEV 1953 is equipped with sensing switch modules (and/or digital signal switch modules). As in Remote Mode, the status of the DEV 1953 is indicated via the LEDs at the device panel and via Web Interface, but the buttons at the device panel are locked and the control functionality of the Web Interface is disabled. The optional digital interface is disabled in Auto Mode as well as the functionality of the different remote protocols (SNMP, Sandar Prosan, Leitch, and QEC) to issue switching commands and to modify the settings of the device. However, is possible to issue status queries and to perform some changes on the operation behavior of the device, e.g. via the Sandar Prosan PMxy commands (chapters 5.6.3.6…5.6.3.9).

Which of the functionalities is activated in Auto Mode can be selected via Web Interface (chapter 5.5.7.3.2):

 the Time Based Switching functionality (chapter 5.5.7.3.4); or  the optional TRAC functionality (chapter 5.5.7.3.5); or  the autonomous switching functionality if the DEV 1953 is equipped with one

or more sensing switch module(s) (and/or digital signal switch module(s)):

5.1.3.1 Autonomous Switching Functionality

The primary input port "In A" and the secondary input port "In B" of the sensing switch module(s) (digital signal switch module(s)) are continuously monitored regarding the present RF level (regarding the present digital signal quality, respectively) if a. the "Auto Mode Assignment" is set to "Autonomous Switching"

(please refer to chapter 5.5.7.3.2), and if

b. the sensing switch module(s) (digital signal switch module(s))

is (are) switched to the primary input port, and if

c. Auto Mode is activated. E.g. in Individual switching mode the device switches a sensing switch module (digital signal switch module) to the secondary input port if

 on the primary input port, the RF level falls below the defined RF threshold

level (the digital signal quality becomes "Fail", respectively) and if

 on the corresponding secondary input port, the RF level is above the

RF threshold level (the digital signal quality is "OK", respectively).

If neither Option 22 (main backup swap) nor Option 28 (automatic switch back) is installed, there will be no automatic switching back to the primary input port. In this case, the switching is to be done explicitly in Local Mode or in Remote Mode.

If Option 22 (main backup swap) is installed, the autonomous switching works in both directions in the same manner as the switching from the primary to the secondary input port (as described above). This means that the device remains switched to the secondary input port unless on the secondary input port the RF level falls below the RF threshold level (the digital signal quality becomes "Fail", respectively) and if on the corresponding primary input port the RF level is above the RF threshold level (the digital signal quality is "OK", respectively).

 Copyright DEV Systemtechnik GmbH 2015-2017 41

Page 42

User Manual DEV 1953

If Option 28 (automatic switch back) is installed and activated (as described in chapter 5.5.7.3.2), the switching back from the secondary to the primary input port is initiated by the RF level rising above the RF threshold level again (the digital signal quality becoming "OK" again, respectively) on the failing primary input port. This switching back is supported by an offset which is an adjustable hysteresis (0 dB, 1 dB, 3 dB, or 5 dB) for sensing switch modules, or which is an adjustable delay (0…10 seconds) for digital signal switch modules.

For the autonomous switching capability has to be considered in addition, whether Individual switching mode or Simultaneous switching mode is activated (chapter 5.1.4) and whether (and which) input ports are disabled (chapters 5.5.4.2 & 5.9.4.3.9.2), since this has an influence on the switching behavior. Therefore, the following scenarios are to be examined for the autonomous switching functionality:

 Switching from the primary input port to the secondary input port in

Individual switching mode:

- If both input ports of a sensing switch module (or of a digital signal switch

- If the primary input port of a sensing switch module (digital signal switch

- If the secondary input port of a sensing switch module (digital signal switch

 Switching from the primary input port to the secondary input port in

Simultaneous switching mode:

- If all input ports of a group (chapter 5.1.4) are enabled, the autonomous

I.e. the device switches only if on the primary input port the RF level falls below the RF threshold level (the digital signal quality becomes "Fail", respectively) and if on the corresponding secondary input port the RF level is above the RF threshold level (the digital signal quality is "OK", respectively).

module) is disabled, the RF level information (the digital signal quality information, respectively) of the port is ignored as a trigger; i.e. the device does not switch to the secondary input port.

module) is disabled, the RF level check (the digital signal quality check, respectively) of this port is omitted. Thus, if the sensing switch module (digital signal switch module) is switched to the (enabled) primary input port and if on the primary input port the RF level drops below the RF threshold level (the digital signal quality becomes "Fail", respectively), the device unconditionally switches this sensing switch module (digital signal switch module) to the secondary input port.

switching is performed for all members of the corresponding group from the primary input ports to the secondary input ports. The condition is that on the primary input port of one or more members of the group the RF level drops below the RF threshold level (the digital signal quality becomes "Fail", respectively) and that on all secondary input ports of the group the RF level is above the RF threshold level (the digital signal quality is "OK", respectively).

ports are) not considered in the switching decision, i.e. the device switches if on the enabled primary input port(s) the RF level drops below the RF threshold level (the digital signal quality becomes "Fail", respectively). There is no autonomous switching if all primary input ports of a group are disabled.

 With (activated) Option 28:

Switching back from the secondary input port to the primary input port in Individual switching mode:

- If both input ports of a sensing switch module (digital signal switch module)

are enabled, the switching is performed as described above. I.e. the device switches, if on the primary input port the RF level is above the RF threshold level again (and the digital signal quality is "OK" again, respectively) plus an offset value (chapter 5.5.7.3.2).

- If the primary input port of a sensing switch module (digital signal switch

module) is disabled, the RF level check (and the digital signal quality check, respectively) of this port is omitted. Thus, the device unconditionally switches to the primary input port.

- The secondary input port is not considered in the switching decision in this

scenario. Therefore, it does not matter whether the secondary input port is disabled or enabled.

 With (activated) Option 28:

Switching back from the secondary input ports to the primary input ports in Simultaneous switching mode:

- If all input ports of a group (chapter 5.1.4) are enabled, the autonomous

switching is performed for all members of the corresponding group from the secondary input ports to the primary input ports. The condition is that on all primary input ports of the group the RF level is above the RF threshold level again (and the digital signal quality is "OK" again, respectively) plus the offset value (chapter 5.5.7.3.2).

- If one (or more) primary input port(s) of a group is (are) disabled, the

RF level information (and the digital signal quality information, respectively) of the port(s) is omitted. Thus, disabling one or more primary input port(s) of a group encourages the switching in this situation, since the signal information of this (these) primary input port(s) is ignored.

- The secondary input port(s) of a group is (are) not considered in the

switching decision in this scenario; therefore it does not matter whether the secondary input port(s) of a group is (are) disabled or enabled.

5.1.4 Individual/Simultaneous Switching Mode

Regarding the signal routing all channels of a DEV 1953 are independent from each other, but the device provides two switching modes: Individual switching mode and Simultaneous switching mode. In Individual switching mode, the installed switch modules can be switched independently from each other. In Simultaneous switching mode a group of switch modules is switched synchronously to the same input port (either to the primary input port "In A" or to the secondary input port "In B"). In Local Mode, the selection between Individual switching mode and Simultaneous switching mode can be performed either via the switching mode push button at the device panel (labeled 8 in the figure of chapter 3.1.1) or via Web Interface (chapter 5.5.4.1). In Remote Mode, the selection between Individual switching mode and Simultaneous switching mode can be performed via Sandar Prosan protocol (chapter 5.6.3.8) or via SNMP (chapter 5.9.4.3.3).

44  Copyright DEV Systemtechnik GmbH 2015-2017

Page 45

User Manual DEV 1953

Note:

 As the factory setting for the DEV 1953, each module slot is forming a single

group for simultaneous switching. This means, that there are sixteen groups with a single member each initially and that there is no functional difference between Individual switching mode and Simultaneous switching mode. To utilize the advantages of simultaneous switching, the group assignment is to be altered via Web Interface (in Local Mode and with Individual switching mode activated, please refer to chapter 5.5.7.3.3).

 If the switch modules being member of a group are in different positions, it is

not possible to activate Simultaneous switching mode. In this case, the device panel channel LEDs of all groups with members that are not in the same position will toggle twice when operating in Local Mode the switching mode push button. To resolve this situation the same switching position has to be established by switching the related (i.e. the Simultaneous switching mode preventing) switch modules in Individual switching mode before activating Simultaneous switching mode.

 Naturally, the Simultaneous switching mode is not available if the device is

equipped with a single switch module, only.

5.2 Initialization of the Device

The device performs a health check and a configuration check during power-up and after a device reset. This takes about 60 seconds; there is no manual configuration necessary, all settings (including the operation mode) after power-up or after a device reset remain unchanged.

Note:

 If not a single switch (or distribution amplifier) module is installed, the device

signalizes this by a permanent event indication (i.e. the channel LEDs at the device panel are blinking and this cannot be stopped).

5.3 Operation via the Device Panel

The local operation (via push buttons) and the status indication (via LEDs) of the device panel were already explained in chapter 3.1.1.

Note:

 The factory default for the operation mode is Remote Mode.

To operate the push buttons at the device panel, the DEV 1953 has to be switched to Local Mode via the mode push button at the device panel (please refer to chapter 3.1.1), via Web Interface (chapter 5.5.2), or via SNMP (chapter 5.9.4.3.1).

5.4 Control via the Digital Interface Options

The digital interface options provide basic monitoring and switching functionality for up to sixteen switch modules, e.g. for the control via a PLC (Programmable Logic Control). The switching status can be monitored for each switch module via relay contacts and the switching can be performed for each switch module via a digital signal. Please refer to chapter 3.1.4 for the different digital interface options, to chapter

3.2.26 for the drawing of the digital interface module, and to chapter 7 for tech-

nical details and for the pin assignment of the digital interface module connector. Note:

 Since the digital interface is defined as a remote interface, it works only if the

device is in Remote Mode.

 If the device is to be switched via the digital interface, it is highly recommended

to disable the CPH (i.e. to change the CPH configuration to "none/configuration program", chapter 5.5.7.2.3) and not to issue switching commands via SNMP. Otherwise, this might cause unpredictable switching behavior of the device.

 When changing the operation mode in Simultaneous switching mode from

Local Mode or Auto Mode to Remote Mode, the setting of the first member of a group determines the switching position of the group!

 When switching the device to Remote Mode, it is not guaranteed that the

device is in the switching position(s) as given by the potentials of the contacts of the digital interface. The switching via the digital interface is slope triggered. Thus, it is recommended to generate a switching event after the activation of Remote Mode for any switch module in Individual switching mode (or for the first member of any group in Simultaneous switching mode) with the slope direction for the desired switching positions, in order to synchronize the device with the digital interface contacts.

5.5 Operation via Web Interface

The Web Interface is a comfortable user interface for operating the product, i.e. the device is controlled via a computer and a Web Browser as the communication application. Several users (assumed the appropriate number of licenses) can access the device at a time. The first license is included in the delivery. It is possible to purchase additional license keys at any time, please contact DEV Systemtechnik.

Note:

 Most of the screenshots shown in the following were made from the

Web Interface of a DEV 1953 equipped with modules as stated in the example of chapter 3.3.2, with applied Option 28 (automatic switch back), and with applied Option 37 (TRAC). Other product configurations may deviate from the layout but not from the basic functionality of the Web Interface. Most of the screenshots were obtained from a device without applied digital signals, thus indicators appear in red, and the digital signal quality indication is "Fail".

5.5.2 The Main Window and Common Features of the Main Tabs

After successful authentication the main window of the Web Interface shows up with the Status Tab opened, which is the default view:

In the top of the window on the left side, the five (or six) tabs are located ("Status", "Control", "Events", "Recording" (only for a DEV 1953 with installed sensing switch modules, please refer to chapter 5.5.6), "Setup", and "Info"). The active tab is highlighted; clicking on an inactive tab opens the corresponding tab instead. In the middle on the top of the window three buttons are located indicating that the device is in Remote Mode (as shown in the screenshot above), or in Local Mode (as shown in the screenshot of chapter 5.5.3), or in Auto Mode. Changing the operation mode of the device via Web Interface is performed by

clicking on the desired button, e.g. clicking in the situation above on the button, highlights the button instead of the button. In the representation

of the device panel in the upper part of the Status Tab, the indicators change correspondingly (here from "Remote" to "Local"). Right to these buttons the currently logged in user (here: "ADMIN") and the permission of the user (here: "admin") are shown. Please refer to chapter 5.5.7.1.2 for more information on this subject. Then, the date and time of the device are displayed right to this information. The correct date and time depends on the proper configuration of an NTP timeserver and of the timezone (chapter 5.5.7.2.1). Note that if there was no timeserver detected at power-up, the device sets the date and time to "01-Jan-2000 00:00".

In the right corner close to the company logo, the button is located. Clicking on this button returns the Web Interface to the Start Screen.

Note:

 It is recommended to finish a Web Interface session by clicking on the

button. This instantaneously releases the allocated license and enables other users to log in.

 A timeout feature (20 seconds) is implemented within the Web Interface, i.e. a

session is automatically terminated (and the allocated license is released) if a user who is currently logged in closes the web browser.

 This means that a Web Interface session is kept open unless the button

is operated or if the web browser (in other words, the connection to the device) is closed.

 It is possible to start a Web Interface session on another computer using the

same user account; naturally, this automatically terminates the session on the preceding computer.

5.5.3 Status Tab

The upper part of the Status Tab shows a simplified representation of the front side of the device. Thus, a quick overview is provided regarding the detected module configuration, regarding the operating status, regarding the switching status, and regarding the health status of the device. The round indicators are equivalent to the physical LEDs at the device panel (green = ok/activated input, red = failure, yellow = Remote/Local/Auto/Simultaneous/Individual, or gray = off), please refer to chapters 3.1.1 & 3.2.25 for details on the indicator information.

In the lower part of the Status Tab, the Active Events Window is located. This window shows pending and not acknowledged events via the related event descriptions with a date/time stamp. The events shown in the next screenshot were triggered for demonstration purpose. Note that the channel LEDs are blinking in the same manner as on the device; this is the reason why the screenshot can imply all channels to be switched to the secondary input port (which is not the case). To obtain more details on the events open the Events Tab (chapter 5.5.5).

5.5.4 Control Tab

The main purpose of the Control Tab is the switching of the device. Additionally, it provides means for changing module specific settings.

On the left side, the Control Tab contains the structuring entries "Groups" and "Switches" in order to branch to the different functionalities of the device. The number of items within both entries (initially) corresponds to the number of installed switch modules and the name of each entry ("Group X" or "Switch X") is the descriptive designator; with "X" (initially) indicating the slot location of the detected module. Each switch module has to be member of a switch group and initially each module is assigned to a separate group that is named correspondingly. This group assignment can be changed, please refer to chapter 5.5.7.3.3. The descriptive designator ("Group X", "Switch X") can be edited by double-clicking the specific item:

Note that on the right side in a group panel or in a switch panel, the port names (here "Channel In 1-1", "Channel In 1-2", & "Channel Out 1") can be edited in the same manner.

Note:

 If changes of settings (which are to be saved explicitly) are applied in a panel of

the Control Tab (or within an entry of the Setup Tab, chapter 5.5.7), they are highlighted in yellow. If a different panel within the Control Tab (or a different entry within the Setup Tab) is selected without saving the change(s) in the current panel or entry, a corresponding warning message pops up. The following figure shows this situation for selecting the "Switch 1" panel after deactivating the "Surveillance Enable" check box of "Channel In 2-2" in the "Switch 2" panel:

 If distribution amplifier modules for ASI/SDI signals are installed, they can be

selected in the same manner within the appearing entry "Distribution Amplifier" (chapter 5.5.4.3) on the left side of the Control Tab.

 Switching and the change of settings within the Control Tab of the Web Inter-

face can be performed by operators with "read/write" or "admin" permission only, and if the device is in Local Mode.

If a module functionality within a functionality item is selected on the left side of the Control Tab, the corresponding panel appears on the right side. The different panels are explained in the following. Note that in the lower right corner of each

panel two buttons are provided for selecting and switching mode.

5.5.4.1 Group

If a group is selected on the left side of the Control Tab, the corresponding group panel appears on the right side where the simultaneous (!) switching of the switch modules being member of the group can be performed.

The screenshot above shows the device with "Group 1" activated, here -to demonstrate simultaneous switching- the group is configured with the first three switch modules as members. I.e. the initial group assignment (each module is assigned to a separate group) was changed via the related setup functionality; please refer to chapter 5.5.7.3.3. The representation of each switch module is realized via two rectangles for the two input ports and via a circle indicating the switch position. For switch modules with RF level monitoring functionality (and with digital signal monitoring functionality, respectively) the present RF levels (and the digital signal quality information, respectively) of each input port are visible within the rectangles. A red background implies, that the RF level is below the RF threshold level (and the digital signal quality is "Fail", respectively), it is green otherwise. The background color of an input port appears in gray if it does not provide any status information or if a port (which is capable of generating status information) is disabled (chapters 5.5.4.2, 5.5.4.3, & 5.9.4.3.9.2). In the screenshot above, all members of the group are in the same switch position

indicated by the same type of circles. Also, the button (lower right corner) and to the button (in the middle of the top) are active, indicating

Individual switching mode and Local Mode of the device. With these preconditions, simultaneous switching is performed as follows:

Note:

 If the members of a group are not in the same switching position, two types of

circles are displayed. In this situation the button is disabled (grayed out):

To (re-)enable in this scenario the button (thus Simultaneous switching mode) either the second, or the first and the third switch module have to be switched via their switch panels (here assuming that all members of "Group 2" are already in the same switching position).

 Note that the switching via Web Interface can be performed only if the device

is in Local Mode and that the switching via a group panel is possible only if the device is in Simultaneous switching mode.

 If the device is in Simultaneous switching mode, it is possible to switch the

group either via the corresponding group panel or via one of the Switch panels of any member of the group.

 If the device is in Remote Mode or in Auto Mode, the and the

switching mode buttons are disabled (grayed out).

5.5.4.2 Switch

If a switch is selected on the left side of the Control Tab, the corresponding switch panel appears on the right side. It consists of two or three sections:

1) In the upper section below the descriptive designator (here: "Switch 4"), first the "Input Port Numbers" and the "Output Port Number" of the switch module are shown as a reference to the index of the SNMP .portTable (please refer to chapter 5.9.4.3.9) and if port specific events are to be identified in the Events Tab (chapter 5.5.5). Then the "Module Type" (here: "DEV 11-0014") and the "Group Assignment" (here: "Group 2") are listed. Additionally -with Option 28 (chapter 5.5.7.3.2) installed and activated-, the line "Automatic Switch Back at" indicates the switch back level; here with "-27.0 dBm" an offset (i.e. 3 dB) to the (standard -30 dBm) RF threshold level setting is displayed.

2) Within the second section, the switching status of the switch module is shown and can be changed. Depending on the active switching mode, either the individual switching of the current switch module can be performed, or the simultaneous switching of the group to which the current switch module is assigned to. The switching mode is

indicated at the lower right of any switch panel by one of the buttons or being activated (i.e. or ).

The screenshot above shows in the middle the measured RF level of each input port on the left side. The green background implies that the level is above the individual threshold, it is red otherwise. The background color of a port rectangle appears in gray if it is disabled (e.g. by deactivating the corresponding "Surveillance Enable" check box), or if it does not provide any status information.

56  Copyright DEV Systemtechnik GmbH 2015-2017

User Manual DEV 1953

The individual switching of a switch module is performed as follows: To switch in Local Mode (!) only the selected module, Individual switching

mode is to be activated; i.e. in this scenario, the button in the lower right corner is to be operated:

Next, click on the circle between the representation of inputs and output, which causes two additional buttons to appear:

After a click on the button, the actual switching is performed and the new status (the module is switched to the secondary input port) is shown:

Please note that the button becomes disabled (grayed out:

), indicating that the device cannot be switched back to Simultaneous switching mode, since the switch modules which are member of the group (here: "Group 2") are not in the same switching position now.

Page 58

User Manual DEV 1953

Note:

• The input ports of many switch modules appear as gray rectangles:

• Enabled (!) input ports of digital signal switch modules which are capable of

judging the digital signal quality are shown as rectangles with a red or with a green background:

• Again, if the device is in Remote Mode or in Auto Mode, the and

the switching mode buttons are disabled (grayed out).

3) For sensing switch modules and for digital signal switch modules a third section appears below the switching section permitting the modification of module specific parameters. Note that after settings have been altered within this

section in Local Mode (!), a click on the button is necessary to apply the changes:

• For both input ports of a sensing switch module, the "RF Threshold" can be

adjusted individually within a certain range.

• The "Surveillance Enable" check boxes are used to enable (default) or to disable

events possibly caused by the input ports of sensing switch modules and of digital signal switch modules.

5.5.4.3 Distribution Amplifier

This kind of panel (within the appearing structuring entry "Distribution Amplifier") is available only for devices with installed distribution amplifier modules for ASI/SDI signals, i.e. for the screenshot above a distribution amplifier module was installed temporarily in the tenth slot. The panel consists of two sections:

1) In the upper section below the descriptive designator (here: "Amp 10"), first the "Port Number" of the module is shown as a reference to the index of the SNMP

.portTable (please refer to chapter 5.9.4.3.9) and if port specific events are to be

identified within the Events Tab (chapter 5.5.5). Then the "Module Type" is listed (here: "DEV 14-0092"). Finally, the "Signal Status" is an assessment regarding the detected signal quality that can be either "Fail" (red) or "OK" (green).

2) In the "Setup" section, the "Surveillance Enable" check box is used to enable (default) or to disable events possibly caused by the related port. Note that after this

setting was altered in Local Mode (!), a click on the button is required to apply the change.

5.5.5 Events Tab

The Events Tab displays a table of the events that were detected by the device. The different events are listed line-by-line, i.e. each event carries a Date/Time

stamp (in the format: "DDD DD MMM YYYY hh:mm:ss", here e.g. "Wed 06 Sep 2017 16:15:29") informing about the last occurrence of that event. The second column is a Counter reporting the number of occurrences of that event (here: "1"). The third column denotes whether that event is Ack.nowledged ("X") or not (" ") (here e.g. " ", i.e.

<space>, meaning not acknowledged). The fourth column shows whether that event

is Pend.ing ("X") or not (" ") (here: "X", i.e. pending). The fifth and the sixth columns inform about the error code No. in Hexadecimal (here e.g. "1302") and in Decimal (here e.g. "4866") notation; the last column reports the related Event Description string (here e.g. "Power Supply 2"), please refer to chapter 6.1.

Below, the buttons and are located: An event can be acknowledged by highlighting (i.e. clicking on) the related line and

by operating the button afterwards. The intention of the acknowledgement of an event is to provide means to mask out a pending event of the Active Events Window in the Status Tab (chapter 5.5.3) and to stop the event indication via device panel (chapter 3.1.1) and via Status Tab (chapter 5.5.3) if all pending events in the table are acknowledged. If a confirmed event occurs again, the counter in the table is increased and the acknowledgement is reset (i.e. the "X" disappears, the Active Events Window reports the event again, and the event indication via device panel and via Status Tab becomes active). An acknowledged and not pending event can be deleted from the list by high-

lighting the corresponding line, followed by clicking on . If a deleted event occurs again, a line is added at the beginning of the table.

Note:

 It is possible to acknowledge (and to delete) more than one entry at a time by

highlighting more events using the <Ctrl> or the <Shift> key of the keyboard in combination with mouse click(s).

 Users with "read" permission only have no rights to acknowledge or to delete

event entries (chapter 5.5.7.1.2).

 If an event is still pending or not acknowledged, it cannot be deleted.  The table content can be stored using the data backup functionality

(chapter 5.5.7.4.2).

5.5.6 Recording Tab

The Recording Tab is available only if the DEV 1953 is equipped with sensing switch module(s). For this type of modules, the RF level data is continuously captured in discrete intervals. The Recording Tab permits the visualization and the external storage of this data. After opening the Recording Tab for the first time in a Web Interface session, two empty diagrams labeled "Overview" and "Details" are shown as in the next screenshot.

In this application, the drop down list "Signal Type" permits the selection of "RF Level" only. After selecting one to three "Signals" via the three drop down lists, the recorded data shows up in both diagrams:

Page 62

User Manual DEV 1953

Note:

 The recording interval and thus the recording duration can be altered, please

refer to chapter 5.5.7.3.1. The data representation initially always comprises the recorded data for the selected items, i.e. it is stretched if the full recording duration is not reached yet, and the graphs indicate via gaps if the device was turned off for a span of time.

 The checkbox labeled "Show Thresholds" enables the display of the related

present threshold for the selected signals. If checked, each threshold is shown as a separate horizontal line with an individual label.

It is possible to magnify the data by drawing a zoom window in either (!) diagram, i.e. by clicking and holding the left mouse button while pulling the mouse over the interesting area:

62  Copyright DEV Systemtechnik GmbH 2015-2017

User Manual DEV 1953

Directly after releasing the left mouse button, the zoomed area appears in the "Details" diagram while the "Overview" diagram is highlighting the zoomed area:

Three buttons are located at the bottom of the Recording Tab: If the recorded data of the selected items was zoomed as described above, the but-

ton resets the data representation to the initial state, i.e. all recorded data for the selected signals is displayed in both diagrams. The remaining two buttons provide the option to store the captured data externally

(without the possibly displayed thresholds!). stores the recorded data of the currently selected signals and the button stores all recorded data of

the device, i.e. the available data of all signals. After operating one of the buttons, a browser specific window pops up and suggests the storage of the data as "recording.csv" and as "recording_all.csv", respectively. The csv (comma-separated values) file format permits the data import e.g. into a MS Excel worksheet: The csv-file is a text file modeling a table. Each line is interpreted as row containing column information, here with the columns delimited by a semicolon (";") character as the column separator.

The number of columns depends on the export method ( vs. ). If the button is selected, the number of columns depends on the

number of signals currently presented. In any case, each signal consists of a "Time" and of a "Value" column; the number of lines depends on the recording duration (over 17000 lines e.g. within two days with the default ten seconds recording interval). The first line of the csv-file is the header line providing the column information. The first entry is assigned to the first signal (e.g. "Channel In 4-1", indicating the (default) port name of the primary input port of the sensing switch module in the fourth slot, please refer to chapter 5.5.4), concatenated with the "Signal Type" (i.e. here always "RF Level") and with "Time". After the semicolon, the same entry is

After import and formatting the "Time" columns to the format "DD-MMM-YYYY, hh:mm:ss" this results in the following table:

Note:

 The decimal separator in the csv-file is the point character ("."), this has to be

considered during the data import of the csv-file e.g. into an Excel worksheet.

 For the data import into an empty MS Excel worksheet select the tab "Data"

and there the icon "From Text". Then locate the csv-file and follow the instructions of the text import wizard.

 The correct time information is dependent on the proper configuration of a

timeserver and of the timezone. The settings can be applied via the network setup of the Setup Tab (chapter 5.5.7.2.1). If no timeserver is configured for the device, the recording of the data starts at 01-Jan-2000, 00:00:00; after a device reset the time is reset to 01-Jan-2000, 00:00:00 as well, but the recording of the data is continued with the time of the last sample. If a timeserver was configured for the device that is not available anymore after a reset, the recording of the data is continued with the time of the last sample as well. Otherwise, if the timeserver is available after a device reset, the recording of the data is continued with the correct time; i.e. this causes a time gap within the data.

If "Autonomous Switching" is activated, the autonomous switching functionality of the device based on the RF level information (and on the digital signal quality, respectively) is enabled in Auto Mode.

2) Time Based Switching The Time Based Switching functionality (chapter 5.5.7.3.4) is enabled in Auto Mode if this entry is activated.

3) TRAC This entry is available and can be selected only if the device is equipped with the TRAC option. The TRAC functionality (chapter 5.5.7.3.5) is enabled in Auto Mode if "TRAC" is activated.

If Option 28 is installed, the automatic switch back functionality can be activated and configured in the section "Automatic Switch Back" within the Auto Mode entry. As described in chapter 5.1.3, with this functionality activated -and the Auto Mode Assignment set to "Autonomous Switching"-, the autonomous switching functionality can be extended in a way that the device in Auto Mode can switch single (if Individual switching mode is active) or groups of (if Simultaneous switching mode is active) signal paths back to the primary input port(s).

Page 74

User Manual DEV 1953

The check box labeled "Enable Automatic Switch Back" is used for the activation/ deactivation of the automatic switch back functionality. If an installed sensing switch module is switched to the secondary input port and if on the primary input port the RF level rises above the corresponding RF threshold level plus an offset value, the device switches back to the primary input port. This offset value (0 dB, 1 dB, 3 dB, or 5 dB) can be selected via the drop down list labeled "Hysteresis for Automatic Switch Back":

If an installed digital signal switch module is switched to the secondary input port and if on the primary input port the signal quality becomes "OK" again for a selected time, the device switches back to the primary input port. This time (0…10 seconds) can be selected via the drop down list labeled "Switch Back Time for Automatic Switch Back (ASI/SD-SDI/HD-SDI/3G-SDI)":

A click on the button applies the changes made. Note:

 If Option 22 is installed, the main backup swap functionality is activated perma-

nently if the Auto Mode Assignment set to "Autonomous Switching"! No explicit adjustments need to be performed.

 By default the Auto Mode Assignment set to "Autonomous Switching" (if appli-

cable) and -if Option 28 is installed- the automatic switch back functionality is activated; is set to "0" dB for sensing switch modules and is set to "10" seconds for digital signal switch modules; these settings are applied as well after a Restore Factory Defaults (chapter 5.5.7.4.1).

5.5.7.3.3 Group Assignment

The Group Assignment entry permits the modification of the assignment of the switch modules to switch groups. Each switch module of a device has to be assigned to a group. As stated in chapter

5.1.4 the factory setting for the DEV 1953 is that each module slot is forming a

single group. This means, that initially there are sixteen groups with a single member each, and that there is no functional difference between Individual switching mode and Simultaneous switching mode. To utilize the advantages of simultaneous switching the group assignment is to be altered. To change the assignment of one or more switch modules using the Group Assignment entry make sure that the device is in Local Mode and that Individual switching mode is activated. Then in the assignment matrix select the row(s) of the desired module(s) and the column(s) of the desired group(s) and click on the square(s). The background of the square(s) becomes yellow:

A click on the button is necessary to apply the changes:

Page 76

User Manual DEV 1953

Note:

 The device has to be in Local Mode and in Individual switching mode to change

the group assignment of a switch module; otherwise the assignment matrix is grayed out.

 It is recommended to use consecutive group numbers (starting from "Group 1")

to keep the reference to the entries in the SNMP .switchGroupTable (chapter 5.9.4.3.5).

 It is suggested to configure groups for the installed switch (!) modules as

desired and to assign all empty slots and all slots populated with a passive module or with a distribution amplifier module to the next vacant group number.

 A group is shown and can be selected within the structuring entry "Groups" on

the left side of the Control Tab (chapter 5.5.4) if it contains at least one member.

5.5.7.3.4 Time Based Switching

Time Based Switching is a functionality to enable the time controlled switching of the device. The following prerequisites are to be considered:

 Time Based Switching is to be configured via the Web Interface, only.  The device needs to obtain the present time from a timeserver, i.e. the

network setup of the device may have to be supplemented with the entry for a valid timeserver, and the local timezone may have to be adjusted, please refer to chapter 5.5.7.2.1.

The present device time is displayed in the top of the window left to the button. Note that if there was no timeserver detected at power up, the device sets the date and time to "01-Jan-2000 00:00".

76  Copyright DEV Systemtechnik GmbH 2015-2017

Page 77

User Manual DEV 1953

For setting up Time Based Switching within the Web Interface, activate Local Mode (in order to suppress unwanted switching actions during the setup).

 As the first step select "Time Based Switching" in the drop down list

"Auto Mode Assignment" of the Auto Mode entry (chapter 5.5.7.3.2) and save the change.

 Next, within the Switching Actions entry (chapter 5.5.7.3.6.1) at least one

switching action needs to be defined.

 After that, at least one trigger of the Time Based Switching entry (see below)

needs to be defined and to be enabled.

 For arming the device for Time Based Switching, activate the Auto Mode.

After selecting the entry Time Based Switching on the left side of the Setup Tab click on the item "Add new trigger" and enter a name in the appearing text field (here: "Wednesday 17:45"). Next, select the name in the list to enable the definition of the trigger (alternatively and if applicable, click on an existing trigger to modify it):

Either a time trigger is defined:

 repetitive for one or more weekdays by checking the corresponding box(es)

(here, We(dnesday) was chosen), or it is defined as a

 single occurrence using the drop down lists below "Day" and "Month" for

defining the date.

Note that when checking one or more weekdays, the drop down lists for "Day" and for "Month" become grayed out and vice versa, when selecting a "Day" and/or a "Month", the weekday check boxes become grayed out. In this case -i.e. to reenable the weekday check boxes-, choose the first entry (blank entry above entry "01") in both drop down lists for "Day" and "Month". After specifying the weekday(s) or the date select the time for the switching event via the drop down lists for "Hour" (here: "17"), "Minute" (here: "45"), and "Second" (here: "00", thus unchanged).

Page 78

User Manual DEV 1953

Then select the Switching Action via the drop down list. Here an action is shown and selected as the default that was defined already via the Switching Actions setup entry (chapter 5.5.7.3.6.1). As the last step in defining a time trigger either activate the trigger by checking the box right to the "Enabled" label, or leave it unchecked if it is intended to set up the trigger in advance:

Finally, click on the button to store the settings made before selecting (or adding) another trigger and/or before activating the Time Based Switching by

clicking on the button.

Note:

 The check box labeled "Enabled" is grayed out and the message "Not enabled in

Auto Mode Assignment" appears if "Time Based Switching" is not activated in the "Auto Mode Assignment" of the Auto Mode entry (chapter 5.5.7.3.2).

 If the connection to the timeserver is not established, this is displayed in the

Time Based Switching functionality via the message: "Warning: The device currently does

not receive a valid time from an NTP server, so time based switching may not work properly. Please check the time server configuration". Time Based Switching can be activated in such a case as

well, but this may cause unwanted switching of the device.

 Neither the activated time triggers nor the activated Switching Actions are

checked for ambiguity or contradictions. The behavior of the device is not predictable in such a case.

 It is recommended to perform Time Based Switching with the device set to

Individual switching mode (chapter 5.5.4.1) and rather to use appropriately configured Switching Actions to avoid unwanted switching behavior.

 To copy a trigger click on the icon left to the trash bin icon of the trigger entry.

The copy which is appearing has the same name but with a leading "Copy of" (which can be renamed by double clicking the name).

 To delete a trigger click on the trash bin icon right to the trigger entry.

A window pops up for confirmation.

 Finally, do not forget to click on the button to activate the Time Based

Switching:

5.5.7.3.5 TRAC

The TRAC submenu is available in the menu item Feature Setup of the Setup Tab only if the device is equipped with Option 37. TRAC (stands for "Trap Receiver Action Controller") is a powerful feature enabling the device to execute Switching Actions (please refer to chapter 5.5.7.3.6.1) based on received SNMP traps or on IP Monitoring. The following prerequisites are to be considered:

 TRAC is to be configured via the Web Interface, only.  If Switching Actions based on received SNMP traps (trap triggers) are pursued,

the DEV 1953 must be configured as trap destination within the device that is sending the traps. For example, if the device is a DEV 1951, activate the SNMP setup (chapter

5.5.7.2.2) there and enter the IP address of the DEV 1953 in one of the four Trap Destination IP Address fields. No changes on the port setting (162) or on the community are required if the TRAC Setup (chapter 5.5.7.3.5.1, description of the upper section) of the DEV 1953 was not changed. Then, one or more traps should be enabled within the SNMP setup of the DEV 1951 before saving the changes. Note that traps received by the device (in the example: the DEV 1953) can be monitored via the Trap Log (chapter 5.5.7.3.5.3).

 If Switching Actions based on IP Monitoring are pursued, the target device

causing switching actions has to support and must be reachable via ICMP Echo Requests (better known as "ping").

 Select "TRAC" in the drop down list "Auto Mode Assignment" of the Auto Mode

entry (chapter 5.5.7.3.2) and save the change.

 It is recommended to activate Individual switching mode (e.g. via the Control

Tab in Local Mode, chapter 5.5.4.1) and to define the necessary Switching Actions (chapter 5.5.7.3.6.1) before the definition of trap triggers or of IP Monitoring triggers and before switching the device to Auto Mode.

The definition of trap triggers is explained within the description of the TRAC Setup entry (chapter 5.5.7.3.5.1); here the usage of the Trap Log (chapter 5.5.7.3.5.3) as definition support for trap triggers is explained as well. The definition of IP Monitoring triggers is subject of chapter 5.5.7.3.5.2.

Page 80

User Manual DEV 1953

5.5.7.3.5.1 TRAC Setup

In the upper section, the TRAC Setup entry is used for the trap receiver settings and for the definition of trap triggers in the lower section. The TRAC Setup section comprises the fields "Trap Receiver Community" and "Trap Receiver Port". By default, the "Trap Receiver Community" contains no entry, thus not any restriction in the reception of traps. When entering e.g. "public" the reception of traps is restricted to traps of the "public" community, only. The standard SNMP trap port 162 is the default "Trap Receiver Port". This value can be changed if required.

It is recommended to click on the button to store the settings made before continuing with the definition of trap triggers.

To define a trap trigger the entries in the section "Trap Trigger" can be defined manually but an assisted procedure is recommended and described next: As the first step, activate the Trap Log entry on the left of the Setup Tab:

The traps received by the device are listed here (for details, please refer to chapter 5.5.7.3.5.3). Select a trap by clicking on the corresponding line in the upper table. After activation, the details of the trap are listed in the lower table named "Variable Bindings":

80  Copyright DEV Systemtechnik GmbH 2015-2017

Page 81

User Manual DEV 1953

After the verification, that the highlighted trap contains the desired information it can be transferred to the section "Trap Trigger" of the TRAC Setup entry by clicking

on :

The click on the button automatically activates the TRAC Setup entry comprising a new entry in the Trap Trigger section named "Added from Trap Log" and the settings for "Source IP", "Enterprise OID", "Trap Specific", and the "Variable Bindings" as obtained from the Trap Log:

Page 82

User Manual DEV 1953

As the next step, it is recommended to alter the name of the trap trigger to avoid confusion when importing another trap entry in the same manner. This is done in the usual way by double-clicking the entry:

After the renaming at least the "Switching Action" is to be selected via the related drop down list (again, the appropriate Switching Actions (chapter 5.5.7.3.6.1) should have been defined already) and the trap trigger needs to be enabled via the "Enabled" check box. If required changes to the "Variable Bindings Matching Rules" table can be applied in addition:

 Existing lines in the table can be deleted by clicking on the red "X" on the right

side. Additional lines can be added using the blue "+" on the right side after the last line.

 Each line listed can be edited in the three columns "OID", "Op." (stands for "Op-

erator"), and "Value". For "OID" and "Value" manual entries are required, the wildcard character "*" can be used in the "OID" column and substitutes a single OID specifier item. For the "Op." entry a drop down list is provided as shown in the following screenshot (the provided operators are self-explanatory; "RE" stands for "Regular Expression", i.e. the "Value" is expected to be in Perl syntax, please refer for instance to http://perldoc.perl.org/perlre.html):

82  Copyright DEV Systemtechnik GmbH 2015-2017

Page 83

User Manual DEV 1953

As the last step, click on the button to store the settings made. All enabled triggers (trap triggers and IP Monitoring triggers) are activated by clicking

on the button.

Note:

 If either entry "Source IP", or "Enterprise OID", or "Trap Specific" is left blank

means the acceptance of any corresponding incoming data!

 Again, the wildcard character "*" (as a placeholder for any character) can be

used in the "Variable Bindings Matching Rules" table within the OID only, e.g. .1.3.6.1.4.1.21035.41.*.1.0 instead of .1.3.6.1.4.1.21035.41.2.1.0.

 The check box labeled "Enabled" is grayed out and the message "Not enabled in

Auto Mode Assignment" appears if "TRAC" is not activated in the drop down list "Auto Mode Assignment" (chapter 5.5.7.3.2).

 Neither the activated trap triggers nor the activated Switching Actions are

checked for ambiguity or contradictions. The behavior of the device is not predictable in such a case.

 To copy a trap trigger click on the icon left to the trash bin icon of the trigger

entry. The copy which is appearing has the same name but with a leading "Copy of" (which can be renamed by double clicking the name).

 To delete a trigger click on the trash bin icon right to the trigger entry.

5.5.7.3.5.2 IP Monitor

The IP Monitoring entry can be used for the definition of triggers in order to switch the DEV 1953 based on the availability or on the absence of a target device, e.g. a video router. Again, the target device has to support and must be reachable via ICMP Echo Requests ("ping").

The definition of a trigger within the IP Monitoring entry is done in the same manner as for time triggers (please refer to chapter 5.5.7.3.4) or for trap triggers (chapter 5.5.7.3.5.1):

84  Copyright DEV Systemtechnik GmbH 2015-2017

Page 85

User Manual DEV 1953

After clicking on "Add new trigger" a sensible name for the trigger is to be entered (here: "1951 unreachable"). Then after selecting the new entry on the left side, the definition of the trigger is performed on the right side. Here, the "Destination IP" (the IP address of the target device) needs to be entered. The "Interval" defines the time between the attempts to ping the target device; the default value is 1 second. The "Number of attempts" (default: 2) is used to decide after how many intervals the "Condition" is fulfilled. The "Condition" can be defined via the drop down list, either "IP unreachable" or "IP reachable". Then the "Switching Action" is to be selected via the corresponding drop down list (again, the appropriate Switching Actions (chapter 5.5.7.3.6.1) should have been defined already) and the trigger needs to be enabled via the "Enabled" check box.

As the last step, click on the button to store the settings made. All enabled triggers (IP Monitoring triggers and trap triggers) are activated by clicking

on the button.

Note:

 The check box labeled "Enabled" is grayed out and the message "Not enabled in

Auto Mode Assignment" appears if "TRAC" is not activated in the drop down list "Auto Mode Assignment" of the Auto Mode entry (chapter 5.5.7.3.2).

 The activated Switching Actions are not checked for ambiguity or contradic-

tions. The behavior of the device is not predictable in such a case.

5.5.7.3.5.3 Trap Log

Page 86

User Manual DEV 1953

This screenshot of the Trap Log was already shown in the description how a trap trigger can be defined; please refer to chapter 5.5.7.3.5.1. The "Trap Log" table covers one entry per trap received by the device. Each line comprises a "Date/Time" stamp, the "Source IP", the "Enterprise OID", and the "Trap Specific" entries. After selecting (i.e. clicking on) a specific line the "Variable Bindings" table carries the specific information of the selected trap, i.e. one (or more) OID(s) with its (their) value(s).

Note:

 The Trap Log remains empty if this device is not configured properly as trap

destination within the device that sends traps (chapter 5.5.7.3.5). In addition, the TRAC Setup (chapter 5.5.7.3.5.1, description of the upper section) needs to be configured accordingly.

 On the other hand, too many traps received by the device may cause the loss

of clarity within the Trap Log. It is to be considered whether the number of traps can be reduced by changing communication parameters on both ends of the transmission chain.

 The number of entries within the Trap Log is limited to 30; the oldest entries

are deleted first.

5.5.7.3.6 Actions

The Actions submenu item within the menu item Feature Setup of the Setup Tab comprises the Switching Actions entry and the Action Log entry.

5.5.7.3.6.1 Switching Actions

The definition of Switching Actions is necessary for the Time Based Switching functionality and for the TRAC functionality. By setting up an action it can be defined which switch module is affected and to which port the switch module is to be commanded.

86  Copyright DEV Systemtechnik GmbH 2015-2017

Page 87

User Manual DEV 1953

After selecting the Switching Actions entry on the left side of the Setup Tab in the submenu "Actions", click on the item "Add new action" and enter a name in the appearing text field. When defining actions it is recommended to enter a meaningful name (here: "to 1-1 2-2 3-1 4-2"). This enables a better distinction when selecting the appropriate action in the setup of the Time Based Switching functionality or in the setup of the TRAC functionality later. Then select the name in the list to enable the definition of the action (alternatively and if applicable, click on an existing action to modify it):

The action is defined by selecting the module outputs (via the check boxes below the "On" label) and then the input port (via the drop down list below the "Input" label) as the target switching position. Depending on the application, one or more actions need to be defined.

Note:

 Do not forget to click on the button to store the settings made

before selecting (or adding) another action, or before proceeding e.g. with the Time Based Switching setup (chapter 5.5.7.3.4), or with setting up the TRAC functionality (chapter 5.5.7.3.5)!

 Again, it is recommended to perform Time Based Switching (and TRAC as well)

with the device set to Individual switching mode. If it is intended to switch a number of switch modules synchronously, rather the definition of an action is recommended which defines the desired target switch positions for the single switch modules.

A window pops up for confirmation. Note that an action cannot be deleted if it is used in a trigger definition; a corresponding message pops up when trying to delete the action:

5.5.7.3.6.2 Action Log

The Action Log captures the Switching Actions performed by the device in Auto Mode. Per entry, it comprises a "Date/Time" stamp, the "Trigger Type", the "Trigger Name" causing the action, and the "Action Type" and the "Action Name" of the performed action. The screenshot above shows three entries, one for each trigger type, which can cause a switching action:

 IP Monitor

the switching action "to 1-1 2-2 3-1 4-2" was caused by the IP monitor trigger named "1951 unreachable" (please refer to chapter 5.5.7.3.5.2).

 Trap

the switching action "to 1-2 2-2 3-2 4-2" was caused by the trap trigger named "1951 in Local" (chapter 5.5.7.3.5.1).

 Time

the switching action "to 1-1 2-2 3-1 4-2" was caused by a trigger of the Time Based Switching named "Wednesday 17:45" (chapter 5.5.7.3.4).

5.6 Control via Remote Interface: Sandar Prosan Protocol

5.6.1 Sandar Prosan Protocol Overview

Messages between the device and the host are transferred as records, i.e. data between unique start and stop characters. Once a complete record is received, the receiver returns the character <ACK> if the record is correctly received and recognized. If the record is incorrectly received, not recognized, or not available, the receiver returns a <NAK> character. If the transmitter receives <NAK> (or no answer e.g. within two seconds), it retransmits the message. The number of retransmissions and delays before a retransmission varies and depends on the current system. Each record comprises a checksum that is inserted -as two characters in hexadecimal notation- between the last data character and the stop character of the record. The checksum is calculated by the modulo 256 sum of all data characters in the record. The record start character <STX>, the record stop character <ETX>, the acknowledge character <ACK>, and the not-acknowledge character <NAK> cannot be transmitted as data characters.

Note:

 The Sandar Prosan protocol is available only if "Prosan" is selected within the

CPH setup of the Web Interface; please refer to chapter 5.5.7.2.3. The protocol is exclusively available via the serial interface; the settings of the serial interface have to be configured accordingly (chapter 4.4.1.2).

 If "Echo in Local Mode" is disabled (factory default), the device responds in

Local Mode with an <ACK> character to the commands Q, XR, AM, AMA, S, or SA, only. If enabled, the responses are equivalent to the responses in Remote Mode. "Echo in Local Mode" can be disabled or enabled within the CPH setup of the Web Interface or via the device specific PMEy commands (chapter 5.6.3.7).

 The device specific PMxy commands (chapters 5.6.3.6…5.6.3.9) are not part of

the protocol standard and can be executed in Remote Mode or in Auto Mode.

 For testing purposes, the Sandar Prosan tool WinProTest v1.01 by Telecast

Norge AS may be used to issue Sandar Prosan commands.

5.6.2 Sandar Prosan Protocol Communication Structure

The basic command structure is: Command:

Notation:

<STX> = record start character (= 0x02) <ETX> = record stop character (= 0x03) <ACK> = acknowledge (complete record received) character (= 0x06)

<NAK> = not-acknowledge (incorrect record received) character (= 0x15)

Note:

 (Initially) always a <ACK> or <NAK> character is returned as a response to a

command.

 The switching command (M, chapter 5.6.3.5) can be executed in Remote Mode

only.

5.6.3 Sandar Prosan Commands

The different commands for the communication with the device are described next.

5.6.3.1 Status Query (Q)

The status query can be sent at any time to the device <STX>Q<checksum><ETX> i.e. <STX>Q51<ETX>

The device answer is <ACK><STX>Q<status_byte><checksum><ETX> e.g. <ACK><STX>Q00B1<ETX>

with the following possible content of the <status_byte>: 00 = Status ok in Remote/Auto Mode 01 = Pending event(s) in Remote/Auto Mode 10 = Status ok in Local Mode 11 = Pending event(s) in Local Mode

5.6.3.2 Query Alarm Messages (AM or AMA)

This is the command for the query of pending events <STX>AM<checksum><ETX> i.e. <STX>AM8E<ETX>

or <STX>AMA<checksum><ETX> i.e. <STX>AMACF<ETX>

The device answer is <ACK><STX>AM001:0000,e{,x

or <ACK><STX>AMA001:0000,e{,x

with: e = 00…99 number of events following

{,x

,…,xe}

= 00…FF if there are events: error code class (first digit) and error code sub-class (second digit) in hexadecimal (!) notation, separated by commas (",")

e.g. <ACK><STX>AM001:0000,00A5<ETX> (no events) or <ACK><STX>AMA001:0000,02,12,1307<ETX> (power supply & power line event(s))

Note:

 The event indication is the upper two hexadecimal digits of the related error

class. The first digit specifies the error class according to chapter 5.9.4.4.2; the second digit defines the sub-class. The events of the second example are in the error class "1", i.e. this denotes events in the area of the power supplies, please refer to chapter 6.1.1. The sub-class of the first indicated event (x1 = 12) is "2", specifying a "Power Line" event, the sub-class of the second indicated event (x2 = 13) is "3", specifying a "Power Supply" event.

 It is not indicated if there is more than one pending and not acknowledged

event of the same error code class/sub-class.

5.6.3.3 System Identification (XR)

This command can be issued in order to obtain device information

The device specific identification data is returned in the format ("⌡" and "⌠" are symbolizing that the two consecutive lines are actually one line)

<ACK><STX>XR:DEV<sp>SYSTEMTECHNIK,<model_number>,<model_type>, ⌡ ⌠<firmware_revision><checksum><ETX>

E.g. for a DEV 1953 with firmware revision G.01:

<ACK><STX>XR:DEV<sp>SYSTEMTECHNIK,DEV1953,16*AB-Switch,G.018C<ETX>

Note:

 <sp> denotes the "space" character.

5.6.3.4 Read Status of Signal Path (S or SA)

This is the command for the query of the switching status of the device

The device answer is a sequence of sixteen three digit numbers, each indicating to which input port the corresponding output port is connected to

e.g. with all modules switched to the primary input port "In A" (i.e. 001):

e.g. with the first (i.e. installed) five modules switched to the secondary input port "In B" (i.e. 002):

with: o1 = the input port number of the switch module in the first slot, either 001: primary input port "In A" or 002: secondary input port "In B"; (…) o16 = the input port number of the switch module in the sixteenth slot, either 001: primary input port "In A" or 002: secondary input port "In B".

Note:

 It cannot directly be identified via Sandar Prosan protocol whether a slot is

empty or populated with a passive module or with a distribution amplifier module.

Page 98

User Manual DEV 1953

5.6.3.5 Set Signal Path (M)

This is the command for switching the switch module ooo to the input port iii.

with: ooo = the switch module number in the range 001…016; iii = the input port number to which the switch module is to be connected to, either 001 or 002.

The device confirms the command with an <ACK> if the command is accepted and with a <NAK> otherwise.

Note:

 It is possible to issue a switch command for an empty slot or for a slot

populated with a passive module or with a distribution amplifier module. Naturally, there is no execution of the switch command.

 If a parameter exceeds the permissible range or if the device is not in Remote

Mode, a <NAK> is returned!

5.6.3.6 Select Remote Control Mode (PMCI/PMCE)

Via these device specific commands, the operation mode can be either set to Auto Mode (PMCI) or to Remote Mode (PMCE); please refer to chapter 5.1.

and

The device confirms both commands with an <ACK> if the command is accepted and with a <NAK> if the device is in Local Mode.

Note:

 If the Auto Mode is activated via the PMCI command, this implies the usage of

the device defined by the Auto Mode Assignment of the Web Interface (chapter 5.5.7.3.2).

 If Auto Mode is activated, no switching command (M, chapter 5.6.3.5) is

executed. The PMCE command has to be issued first, to get back the remote switching control via Sandar Prosan protocol.

5.6.3.7 Select Echo in Local Mode (PME0/PME1)

Using these device specific commands "Echo in Local" can be disabled (PME0) or enabled (PME1). If "Echo in Local" is disabled and if the device is in Local Mode, the device responds to queries (Q, XR, AM or AMA, S or SA) with an <ACK> character only.

and

The device confirms both commands with an <ACK> if the command is accepted and with a <NAK> if the device is in Local Mode.

Note:

 Alternatively, "Echo in Local" can be enabled or disabled within the CPH setup

of the Web Interface (please refer to chapter 5.5.7.2.3).

5.6.3.8 Select Switching Operation Mode (PMOI/PMOS)

The switching mode can be set via these device specific commands to Individual switching mode (PMOI) or to Simultaneous switching mode (PMOS), please refer to chapter 5.1.4.

and

The device confirms both commands with an <ACK> if the command is accepted and with a <NAK> otherwise. The commands are rejected in Local Mode and the PMOS command is rejected in Remote Mode or Auto Mode if the preconditions for Simultaneous switching mode are not given. This means that all members of all groups (with two or more members) have to be in the same switch position; i.e. all switch modules of a group are switched to the primary or to the secondary input port (chapter 5.1.4).

5.6.3.9 Select Power Supply Monitoring Mode (PMP0/PMP1)

With these device specific commands the power supply monitoring can be disabled (PMP0) or enabled (PMP1). If disabled, the reporting of all power supply events via the query command AM (or

AMA) (please refer to chapter 5.6.3.2) including the Q command (chapter 5.6.3.1) is

suppressed.

and

The device confirms both commands with an <ACK> if the command is accepted and with a <NAK> if the device is in Local Mode.

Note:

 The successful execution of these commands modifies bit 1 of the SNMP

.errorEnableMask (chapter 5.9.4.4.2).

5.7 Control via Remote Interface: Leitch Protocol

5.7.1 Leitch Protocol Overview

Like the Sandar Prosan protocol, the implementation of the Leitch protocol provides a standard for the communication between the device and a host. The interface can be used for the monitoring and for the switching of the device. Within the Leitch protocol standard it is distinguished between two protocol modes: the Leitch Terminal Protocol and the Leitch Pass-Through Protocol. DEV Systemtechnik has implemented a subset of the Leitch Pass-Through Protocol. Only one Leitch Terminal Protocol command is implemented: "Enable Reporting" is the command to switch to the Leitch Pass-Through Protocol mode. The Leitch protocol is implemented to work via TCP/IP on port 23 (standard Telnet port), and/or via the serial interface.

Note:

 The Leitch protocol is available only if "Leitch" is selected within the CPH setup

of the Web Interface; please refer to chapter 5.5.7.2.3. If it is intended to use the serial interface to control the device via Leitch protocol, the settings of the serial interface have to be configured accordingly (chapter 4.4.1.1).

 If "Echo in Local Mode" is disabled (factory default), the device responds in

Local Mode with the Leitch Error Message (see below) to any valid Leitch command which returns a response in Remote Mode. If enabled, the responses are equivalent to the responses in Remote Mode. "Echo in Local Mode" can be enabled or disabled within the CPH setup of the Web Interface.

 The Leitch protocol implementation on this device distinguishes between "Indi-

vidual Switch Level Assignment" being enabled (factory default) or disabled. The selection is performed via a check box in the CPH setup of the Web Interface and has impact on the behavior of the "Request Crosspoint Status" command (chapter 5.7.4.5), and on the behavior of the "Direct Crosspoint Take" switching command (chapter 5.7.4.6). Basically the selection alters the perspective on the arrangement of the switch modules within Leitch levels (<Lvl>) and destinations (<Dest>) in Individual switching mode: (a) If "Individual Switch Level Assignment" is enabled, the single switch

modules are addressed via the level, the destination is always "0", i.e.

- Level 0/Destination 0 ≡ the switch module in the first slot,

- Level 1/Destination 0 ≡ the switch module in the second slot,

- Level 2/Destination 0 ≡ the switch module in the third slot, (…).

(b) If "Individual Switch Level Assignment" is disabled, the level is assigned to

the groups and the destination is assigned to the single switch modules. Some examples:

- Level 0/Destination 0 ≡ the first switch module within Group 1,

- Level 0/Destination 1 ≡ the second switch module within Group 1, and

- Level 1/Destination 1 ≡ the second switch module within Group 2.

Switch Level Assignment" is enabled or disabled. In both cases, the level is assigned to the groups and the destination is assigned to the single switch modules according to perspective (b).
