SYSTEM OVERVIEW
1. System Overview
Thank you for purchasing an FNER Expandable Routing Switch. FLEXNET’s FNER series switches are based on the same technology as our popular FNEM Series Modular Programmable RF Switches. They were developed to address the increasing need for expandable RF switching in telecommunication network signal processing centers and are equally suitable for audio/ video, baseband, data, IF, and RF switching requirements.
The FNER is perfect for centralized test and measurement applications in networks that are monitoring large numbers of RF signals. Each FNER system is compatible with most monitoring and control systems and can be expanded in 16x1 modules up to a maximum capacity of 128x1. Control of the FNER occurs from a front panel keypad or remotely via computer (serial or TCP/IP). The excellent RF performance of the FNER is achieved through proprietary technology.
Each system is supplied with a control unit. From this unit, an operator may make RF signal routing changes or check to see
the input currently dened. The control unit is also supplied with serial (RS-232 and RS-422/485) and Ethernet (10BaseT
TCP/IP) control ports to allow remote control of the FNER system. This operating manual attempts to familiarize you with the different capabilities and features of FNER systems.
1.1 System Features
FLEXNET systems are equipped with many standard features that make the system highly congurable for our customers.
CHAPTER 1: SYSTEM OVERVIEW
1.2 User Permission Feature
The FNER system features user permissions. This is congured by setting up user accounts with names, passwords, and
permissions. These accounts set limits to what system setting users can change. After an account is set up by the administrator, the user logs into the system and the settings in their account determine if they can change the output or not.
The primary benet of our access control feature is users are protected from the unintentional or accidental RF connection
change. This system is much more robust in a larger system with multiple inputs and outputs, but access control for an FNER still gives the option to require login before the output can be changed.
1.3 Access Control Feature
The FLEXNET matrix system also features access control. The control module in our system has four ports of access that are available for user interface. These are a front panel keypad, Ethernet port, Telnet port, and a Control In port. Users can control the system from any one of these access ports.
Access control can be turned on or off for each one of these ports. This feature enables or disables the login requirements before a user may make a change to the output.
If access control is enabled for a port, the user must rst log in with a user name and password before any changes can be
made. With different access control settings, a user could change the connections from a serial port but be required to log in with permissions from the keypad or the Ethernet port.
1.4 System Upgrades
You can even upgrade your system later to increase the number of inputs available to you. Each FNER system can be
congured for up to 128 inputs. Contact us at ATX Networks and we can help you with your growing communication needs.
1.5 Modules
Two types of modules comprise an FNER system: an MCP 128 (8x1) controller and a 16x1 switching module. Every FNER system consists of one MPC 128 and 1 or more switching modules. A minimal FNER switching system consists of a single MPC 128 and one switching module.
1.5.1 MPC 128
The MCP 128 provides master control capability via the front panel keypad/LCD display or computer interface (serial or TCP/ IP). The unit receives commands from the keypad or computer and controls the individual switching modules. From this unit,
an operator can make routing changes or check to see the path currently congured.

CHAPTER 1: SYSTEM OVERVIEW
1.5.2 FNER Switching Module
The FNER Switching Module is a 16x1 unit that utilizes solid state switching elements to provide seamless switching speeds (nanoseconds). Up to eight switching modules may be combined in a single FNER system. The total number of switching modules required for a system is equal to the total number of system inputs divided by 16. Every switching module is equipped with two inter-module serial ports (“CONTROL-IN” and “CONTROL-OUT”) that are used for communication with other FNER modules.

CONNECTIONS & PROTOCOLS
2. Connections & Protocols
2.1 AC Connections
All AC power cords are included with your system when it is shipped. If using an AC power cord that is not FLEXNET, make sure it is shielded and has a grounding plug. FLEXNET uses these power cords because they help isolate AC noise from the RF signals.
2.1.1 Voltages
Our internal power supplies are auto-ranging. This means that you can connect an acceptable range AC source to the unit and it will automatically accommodate the new source voltage. The power supplies can operate from 85VAC to 265VAC at 47Hz to 63Hz.
Both module types have a +5 and –5 Volt supplies. Each supply will have one LED per power supply on the front panel to indicate the staus of the power suplpy. Each of these LED’s is labeled to indicate which volage supply the LED is a monitor for. This allows you to detect any failures and service them quickly. If any of the LED’s are extinguished and the power switch is on, consult the troubleshooting guide immediately.
CHAPTER 2: CONNECTIONS & PROTOCOLS
2.2 RF Signals
2.2.1 RF Testing
Every FNER module is fully tested. Each module is checked and rechecked for signal integrity every crosspoint is tested to guarantee proper system operation at the factory.
2.2.2 RF Connections
All RF connections are made by connecting source(s) to the input(s) and destination(s) to the output(s). When connecting, be sure that the pin at the center of the RF connector is properly inserted into the F connector on the units. A bent pin will not pass the RF signal correctly.
NOTE: All inputs and outputs are DC blocked. You cannot send power through the FNER to power other devices.
2.3 Control Ports
Modules “talk” to each other through cables connected to the control ports on the rear panels of the modules. These connections are made at system set up, and in most cases never need to be changed.
2.3.1 Control Ports Connectors
There are two DB9 type connectors on each module. The Control In and Control Out ports are always DB9 type female connectors.
The pin numbering is the same for the connectors as well. Looking at the rear panel, pin 1 is at the top left, pin 5 is at the bottom left, pin 6 is at the top right, and pin 9 is at the bottom right.
The control ports of the FNER 16x1 Switching modules and the control out port of the MPC 128 are only for FLEXNET communications. See the appendix for wiriring instructions.
The control in port of the MCP 128 is user congurable and is used for serial data control of the system. The pin denitions
are listed in the table below.

2.4 MPC 128 Control In Port Connection
If you are using a computer to control the FNER, you can use a direct serial connection to the Control In port. For serial control, connect a serial cable (RS-232 or RS-422/485) from the computer to the 9-pin SERIAL port on the rear panel of the MPC 128. The connector is shared for both RS-232 and RS-422/485. Do NOT use a NULL MODEM adapter or crossover cable. Use a straight through 1 to 1 cable.
2.4.1 MPC 128 Control In Serial Communication Settings
The serial port parameters are the same whether you are using RS-232, RS-422 or RS-485. The parameters are xed at 9600
baud, 8 data bits, no parity, and 1 stop bit (8N1). The command protocol for controlling the switch is provided in the appendix.
2.4.2 MPC 128 Control In RS-232 Description
RS-232 was designed for communication of local devices, and supports one transmitter and one receiver. This standard uses single ended signals over unbalanced, unterminated wires. Single ended means the signal is sent over one wire with respect to a single ground source. Unterminated means the signal lines do not have impedance matching at the line ends. This interface is useful for point-to-point communication at slow speeds and over short lengths of cable. Most PCs come equipped with one or more RS-232 serial ports.
2.4.3 RS-232 Advantages/Disadvantages
RS-232 is easy to implement and has been standardized and accepted for years. Due to the nature of RS-232, the signals are susceptible to noise and grounding problems. These problems set a limit to cable lengths. Quintech recommends if using RS­232 that the cable length be limited to 20 meters or approximately 60 feet. RS-232 is also only point-to-point communications so only two devices will typically communicate with each other over the RS-232 standard.
2.4.4 MPC 128 Control In RS-422 Description
In RS-422 communications, a pair of twisted wires is used to carry a signal. The data is encoded and decoded as a differential voltage between the two lines. As a differential voltage, in principle the interface is unaffected by differences in ground voltage between sender and receiver. For more details on differential signaling, refer to the “RS-485” section of this document.
2.4.5 RS-422 Advantages/Disadvantages
RS-422 differential signals over twisted pair wires are less affected by noise. They therefore can communicate at faster rates and over longer distances. RS-422 is better than RS-232 but it still is limited to one master and up to ten receivers on the bus. Recommended maximum length is 4000 feet. The FLEXNET RS-422 standard is limited to 10 receivers.
2.4.6 MPC 128 Control In RS-485 Description
The MPC 128 can be congured to communicate in RS-485 standard. For all RS-485 information, refer to the “RS-485” section of this document.
2.4.7 All Control Port Connections except MPC Control In
Before powering up the units, make sure all of the control cables are properly installed. All FNER modules should be daisy-
chained together, with the MPC 128 unit occupying the rst position in the chain. Connect the CONTROL OUT port of the MPC 128 to the CONTROL IN port of the rst 16x1 module in the chain. The CONTROL OUT port of that module connects to
the CONTROL IN port of the next 16x1 module, etc. The last module in the chain will have an unused 9-pin connector labeled CONTROL OUT.
2-2 FLEXNET – FNER Expandable (Modular) Routing Switches – Installation & Operation Manual
Page 9
Note that the maximum control cable length that can exist between FNER modules is 6 feet. Refer to the appendix for proper control port conections.
2.5 Ethernet Port
The MPC 128 has the ability to communicate over Ethernet. The system has a 10BaseT or 100BaseT Ethernet port depending on options ordered. The Ethernet port supports a Telnet interface, TCP/IP and SNMP. All commands are sent to
the congured IP address and port. The command protocol for controlling the switch is provided in Appendix D.
2.5.1 Ethernet Connections
For Ethernet connections, connect the MPC 128 to a network port or router via the Ethernet port using a standard cable. You can also connect directly to the computer’s network port, but this requires a crossover cable. Standard and crossover Ethernet cable pinouts are provided in Table 2: Ethernet Cable Pinout.

CHAPTER 2: CONNECTIONS & PROTOCOLS
2.6 Ethernet Command Protocol
2.6.1 TCP/IP
The same command protocol is used for control over Ethernet TCP/IP and the serial port. Since the same command formats are used, the command packet will contain a serial address. This address must match the serial address of the MPC 128 or
the packet will be rejected, even though the address is unnecessary when the command is sent over TCP/IP. To avoid any
problems, commands sent over TCP/IP should use the broadcast address “FF” hexadecimal.
2.6.2 Telnet
A Telnet console window is also provided for conguring and controlling the matrix. A command mode is provided where the
same protocol commands can be issued but no serial address or packet headers are required. See Appendix D for more information.
2.6.3 SNMP
SNMP or Simple Network Management Protocol is now implemented on all MPC 128s. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices.
SNMP works by sending messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases and return this data to the SNMP requesters.
To use the protocol it has to be turned on from the front keypad rst. Refer to “SNMP” section.

Figure 4: Interface Options Menu
Figure 5: Serial Interface Menu
4.2.2 Valid Addresses
Addresses can be set from 00 to FE hexadecimal. The unit only responds to commands sent over the serial bus that contain a matching address. The only exception is the address “FF” which is a broadcast address. All units will respond to a command containing FF as the address regardless of its current address. For this reason, FF should not normally be used as a unit address.

network programming, particularly socket programming.
4.5.3 COMM Port Number Default Setting
The default setting of the COMM port is 9100. This number was selected because it is a port number that is not widely used or registered by IANA (Internet Assigned Numbers Authority). Most applications use much lower numbers like 1000 or less.
4.5.4 Why Change the COMM Port Number?
In almost all cases, there is not a conict and the port number will be left at the default of 9100. In case your network happens
to be using port # 9100 for some reason, you can change FNER’s port number to some other value to avoid communication
conicts.

4.5.6 Why Reset the Password?
The password can be set with the ELP command from a communication port on the MPC 128. You can nd more information
about this in the FNER protocol document found in the appendix. This ELP command allows the user to use almost any ASCII hex values to set the password. The user can even use ASCII
hex values that are not found on a standard keyboard. If the password is accidentally programmed with a Hex value that can’t be typed in from a keyboard then the password needs to be reset.

Option 1 “Monitor and Control” from the main menu will load a Connection Status screen similar to Figure 15. The screen may have more options available if you are logged in with permissions or access control is disabled. For more information on permissions, refer to section “Access Control“.
Figure 15: Connection Status wo/Permissions
If the user is logged on with permissions or access control for the local keypad setting is off, the Connection Status screen will look more like Figure 16.
CHAPTER 5: CROSSPOINT CONNECTIONS
5.2 Changing a Connection
This function is available if the user is logged on with permissions or access control for the local keypad setting is off. These permissions are discussed in the “Access Control” section of the manual. Pressing F1 will allow the user to change the input connected to the output.
The Change Connection screen of Figure 17 is displayed when F1 is pressed on the Connection status screen. It allows you to change the input connected to the output.
The menu heading will change from “Status” to “Change”. Select the new input by either typing it in or scrolling through the available inputs with the arrow keys. Press F1 to enter the change. No connection will be made until you press F1. To exit back to the main menu without making any changes press F4.

CHAPTER 5: CROSSPOINT CONNECTIONS
The F2 button operates as a toggle. Pressing it once will lock the connection as currently specied. Pressing it again disables
the lock thereby allowing changes to be made. The F1 button will have no effect upon the output’s connection status while
the lock is enabled. When an output’s connection status is locked the word “Locked” will appear to the right of the “Status ↑↓
” label as shown in Figure 18. The connection must be unlocked before any changes to the connection can be made. This feature was added for additional protection against an accidental crosspoint connection change.

RS-485
6. RS-485
6.1 Why an RS-485 Section?
In the past, there have been questions as to how to handle certain RS-485 communications setups with FNER systems. This
section was written to eliminate confusion about the FNER RS-485 communications, specically termination. This section discusses the major points of RS-485 communications, including specic details such as signaling, cabling, pinout, and
termination settings.
6.2 RS-485 Basics
In order to discuss RS-485 lets review the basics of RS-232 for comparison. RS-232 in simplest terms is a three-wire interface: one transmit, one receive, and one common ground. This is called an unbalanced signal.
It’s a simple protocol but because signaling is in reference to a common ground, the speed and cable lengths are severely limited. RS-232 is typically only a few feet and usually limited to less than 20,000 bits per second. Rather slow for today’s standards.
6.2.1 Balanced vs. Unbalanced
RS-485 standard uses balanced differential signals. In balanced signaling there are two lines. One signal carries the true signal and the other carries the same signal except 180 degrees out of phase. The receiver then reads the difference between the two signals. A basic diagram is shown in Figure 19. A ground wire does exist but it has nothing to do with how the receiver determines the logic level of the signal.
CHAPTER 6: RS-485
Balanced Line Interface
Transmitter Receiver
6.2.2 Voltages & Signaling
A pair of wires is used to carry each signal. The data is encoded and decoded as a differential voltage between the two lines. A typical truth table is shown below.
VA-VB < -0.2v = Logic 0 VA-VB > +0.2v= Logic 1
As a differential voltage, in principle the interface is unaffected by differences in ground voltage between sender and receiver.
6.2.3 Noise Immunity
Furthermore, if lines A and B are close together, they will be affected almost identically by external noise. If the lines are also twisted together, then neither line is permanently closer to a noise source than the other. Hence, the well known “twisted pair” is extremely effective in eliminating noise from the signal. Due to the nature of the differential receiver, any equivalent noise on both wires is cancelled out.
Line A
Line B
Figure 19: Balanced Line Interface
6.2.4 Number of Devices
RS-485 standard allows 32 devices on one bus where RS-232 is typically only a one to one connection. The MPC 128 can be on an RS-485 bus with up to and including 31 other devices.
FLEXNET – FNER Expandable (Modular) Routing Switches – Installation & Operation Manual 6-1
Page 22
CHAPTER 6: RS-485
6.2.5 Master/Slave
Most RS-485 systems use Master/Slave architecture, where each slave unit has its unique address and responds only to packets addressed to this unit. These packets are generated by the master, which periodically polls all connected slave units. Only communications sent to the assigned address will cause a response by the MPC 128 on the bus. This is why it is important to assign the MPC 128 on your 485 bus a unique address.
6.2.6 4-Wire & 2-Wire Systems
RS-485 has a 2-wire and a 4-wire standard. FNER uses the 4-wire standard. This allows master to send data out one pair of wires and the slaves sends data back to the master on the other twisted pair.
6.2.7 Cable Lengths
FLEXNET recommends the same cable length as the RS-485 standard. Your RS-485 cable length can be up to 4000 feet between nodes.
6.2.8 Signal Reection
As data speeds and cable lengths go up, the problem of signal reections becomes important. Lines must be properly terminated by a resistor that makes the cable look electrically like it is innitely long. An innitely long cable, of course, can have no reected signals because the far end is innitely far away. When this reection occurs it propagates from one end of the wires to the other end and back repeatedly. Therefore, to add something to x this reection you only need to take care
of the end of the cable, not any nodes in between the ends. When devices are daisy chained together, the MPC 128 between
the rst and last unit in the chain do not need to have termination resistors. If the MPC 128 is the last in line of a RS-485 bus
then the control termination should be on.
6.2.9 Receiver/Transmitter Termination
RS-485 termination is required to eliminate signal reection as discussed earlier. There is a twisted pair for sending data
from the PC to the MPC 128 and there is another twisted pair for the MPC 128 to transmit to the PC. Therefore, in a four wire RS-485 bus you only need to terminate the receivers. FNER RS-485 termination therefore is only applied to the internal receivers and not the transmitters.
6.2.10 Biasing Resistors
When an RS-485 network is an idle state, all nodes are in the receive mode and the transmitters are tri-stated. When this
happens the state of the line is undened. Bias resistors are nothing more than a pull up resistor on line B and pull down
resistor on line A to guarantee logic high when the bus is idle. When RS-485 termination is turned on these two resistors and the termination resistor are connected to the RS-485 receiver.
6.3 Which Ports are RS-485?
The Control In port on the MPC 128 is the only RS-485 port available on an FNER system. Also to use RS-485 communications the port has to be set up in 485 mode.
6.4 Summary
So now, we understand from the previous sections that FNER RS-485 communications only needs to terminate the ends of the cables and we only need to terminate the receivers. Internally the MPC 128 adds a termination resistor and two bias resistors when termination is turned on.
6.5 Front Panel RS-485 Termination

6.5.1 RS-485 Control In Port Termination
The MPC 128 Control In port can be congured for RS-485 communications. If the Control In port is congured for RS-232 communications then the Control In termination should be off. If the Control In port is congured for RS-422 or RS-485
communications and it is the last unit on the bus, then the control termination should be on. If the MPC 128 is not the last unit on the bus then the control termination should be off. If you are not using RS-485 or RS-422 on the Control In port then leave this setting off.

7.8 Exiting Download Mode
If you “accidentally” put the MPC 128 in download mode, the only way get it out of this
mode is to either download the rmware or power cycle the MPC 128.
7.9 Firmware Upgrade Kit
A rmware upgrade kit only comes from ATX Networks service personel. A rmware upgrade kit will come as a zipped set of les that will contain all the les needed to prepare and download new rmware to your MPC 128. Instructions on how to do this procedure will be included in the zip le. Most upgrade kits include les to download from the Ethernet port or the serial
port.
7.10 Firmware Download Instructions
The instructions to download rmware are always included in an upgrade kit. There are instructions for an Ethernet download
and separate instructions for a serial port download.
7.11 Firmware Download Preparation
Write down the settings for your system before you start the download process. Record all the settings under the conguration menu and the Interface Options menu. These setings will be overwritten during a rmware download. You will also have to
recreate any user acounts, user names, and passwords. Input – Output connections will also go back to factory defaults as well.
A rmware download is not something that can be done in the background while the switch is operating. A rmware download will overwrite all settings in the system. After a successsful rmware download the system settings will be set to FNER
defaults. These defaults are listed in the protocol document but listed here again for your convenience.

The crosspoint connections will also revert back to 1 to 1 connections. Input 1 connected to output 1, input 2 connected to output 2, ect.
7.12 Ethernet or Serial Port Download?
If the rmware is downloaded from the Ethernet port the MPC 128 will reboot itself after completing the download. If the
download is done via serial port the power must be cycled manually after the download is complete. Both methods will
upgrade the mware they just use different ports and methods. If for some reason your rmware is corrupted or your Ethernet connection is not working, you can still upgrade the rmware through the serial port. The ethernet connection connected
directly to the PC ethernet card is the easiest method.
7.13 Why Download Firmware?
New rmware is continually being developed to enhance the system features, make the system easier to use or simply add a new feature that a customer requested. These rmware upgrades when available are not ususally nesseccary but may enable you to have more features previously not implemented on your rmware version.
If you feel you might need to upgrade your rmware, contact ATX Networks for the latest available rmware version for your
system.
7.14 Why Is Downloading Failing?
FLEXNET – FNER Expandable (Modular) Routing Switches – Installation & Operation Manual 7-5
Page 30
CHAPTER 7: FACTORY CONFIGURATION SETTINGS
Some FLEXNET customers have encountered problems while downloading new rmware. Listed here are some of the most common solutions to problems associated with a rmware download.
7.14.1 Serial Port Download Method Solutions
1. Use a one to one straight through serial port cable. Do not use a null modem cable or adapter.
2. Test the cable with an Ohmmeter to make sure each pin is connected to the same pin on both ends. Pin 1 connected to only pin 1, pin 2 connected to only pin 2, ect. Test all nine pins. If there are pins that are not connected, the
download will not work.
3. Before starting the download, the MPC 128 has to be in rmware download mode as shown in Figure 31.
4. If using RS-232, check that you are connected to the Control In port
5. Copy the unzipped upgrade kit and run the applications from your root C or D drive. A directory path with more than 104 characters causes problems with some PC operating systems.
6. Make sure the COM port number in the rabbit eld utility matches the com port number you are connected to on your
PC.
7. Try bumping down the baud rate to 57600 in the RFU utility.
8. Make sure the RFU utility is pointing to the correct les:
Cold Loader = coldload.bin Pilot BIOS = pilot.bin
Flash table = ash.ini
9. Make sure the serial port mode is congured properly (RS-232, RS-422, or RS-485).
7.14.2 Ethernet Download Method Solutions
1. If for some reason the rmware and/or Ethernet connection is no longer working you must download through the
serial port.
2. The MPC 128 does not have to be in rmware download mode to upgrade the rmware via the Ethernet port.
3. If connecting directly to a PC network card, use a cross over CAT5 Ethernet cable.
4. If you are connecting to a hub or switch, use a 1 to 1 straight through CAT5 Ethernet cable.
5. Check the cable for pinched or broken conductors. This is more common than you think.
6. Check the IP address, gateway and subnet mask of your PC. Make sure the MPC 128 gateway and mask are the same.
An easy solution is to turn on DHCP and power cycle the MPC 128. This will allow your Ethernet DHCP server to assign the three addresses to the MPC 128.
You can also connect to the MPC 128 directly. These 3 addresses consist of 4 sets of numbers. These individual numbers range from 0 to 255. They are addresses that
allow the PC to nd the MPC 128 on the network. If the mask or gateway for the PC doesn’t match the MPC 128 mask and gateway, you may be able to see the MPC 128 on the network but a rmware download will not work. Make sure the rst
three sets of numbers match the gateway.
Make sure the IP address of the unit has the rst three sets of numbers as the gateway and IP of the PC.
To nd the IP gateway and mask numbers:
Windows® 95/98: Open a dos window Type winipcfg
A window will be displayed that shows your PC’s conguration.
Windows NT/Me/2000/XP Select Start > Run. Type command into the dialog box, then click OK.
In the resulting command line window, type ipcong /all.
The IP address, Subnet mask, and default gateway will be listed.
6. Copy the unzipped upgrade kit to your root C or D drive. A directory path with more than 104 characters causes problems with some PC operating systems.
7. Make sure the Netloader.exe program can nd your MPC 128 on the network before trying to download.
8. Make sure the Netloader.exe program is pointing to the correct binary les.

ACCESS CONTROL
8. Access Control
FLEXNET denes Access control as: a means to limit the ability of people to mess things up. Our system limits a person’s access to the system in several ways. One is the factory code needed in order to get to the conguration menu, the second
is locking the keypad, and the third is enabling access control, and creating user accounts and assigning permissions. Access control for the FNER system is quite simple. There is only one output and 8 different accounts. Simply allow or deny
access to the output for the 8 users.
8.1 Access Control Overview
Access control for users was created for customers who had problems with unauthorized changes occurring to their switch
settings. If this is not a problem, you can simply disable access control in any combination or on all ve ports. If access
control is disabled on a communications port, than anyone using that port has the ability to change any setting or the output connection on the FNER system.
If access control is enabled on a port the user has to login with an assigned name, assigned password, and will be pre assigned permission to change the output connection or not.
Therefore, if access control is enabled for a port, a user can only change the output if logged in and he has permission from the Admin to change the output.
CHAPTER 8: ACCESS CONTROL
8.2 System Access
A FLEXNET matrix is controlled by a standard Universal Control Module (MPC 128). The MPC 128 accepts control commands
from external sources that tell it how to switch the matrix or congure various system options. A standard MPC 128 has four
control ports that will accept commands:
Local: Front panel keypad and LCD.
Control In: The “PC Control In” connector. This is typically, where a control computer or PC is connected. The port can
be congured as RS-232, RS-422, or RS-485 and accepts 9600-baud 8N1 data. Command data is sent as an STX/ETX bounded packet with checksum as dened in the protocol document.
COMM Port: Ethernet. The exact Ethernet port is user dened with the default Ethernet port set at 9100. It accepts the same
command packet that is used on the serial port. This makes it easy for a single driver to be used for both serial and Ethernet connections.
Telnet: Telnet console window. This provides an ASCII interface with a cursor for keyboard entry of commands.
The system is highly exible and the access control feature can be congured to be on or off for each of the 4 possible control
ports on a control module.
8.3 Port Access Control Enable/Disable
Selecting “3. Access Control” at the Features Menu displays the Port Access Control Enable/Disable screen. Through this screen, you can designate whether the access control system is on or off (i.e., in effect or disabled) for various control ports.
Note: The Access Control option only appears in the Features Menu when you are logged in as the administrator. This is true regardless of whether access control has been enabled for local
control.
To get to the Port Access control Enable/Disable screen from the main menu: key sequence 2, 1, (factory settings code number + F1), 3, 3

CHAPTER 8: ACCESS CONTROL
The ports for which access control can be on or off are as follows: Local - Keypad Remote - does not apply to SRX systems Ctrl-In - PC Control In COMM Port - Ethernet Port Telnet - Telnet Console
Use the up and down scroll arrows to display the port for which access control will be congured, then press the F1 key to
toggle access control on or off for that port. Press F4 to return to the Features Menu. Once access control is enabled for a port, it will only accept passive monitoring commands unless a valid user logs in to that
port. These commands allow for passive monitoring of the matrix but do not allow changes to be made: C, F, KS, O, OS, and Q. All other protocol commands will return with a “command unavailable” (NAK u) response. See the 2.15.06 protocol document for more information.

8.4 Access Control Menu
Option 3 of the main menu will load the Access Control Menu screen shown in Figure 39.
From this menu, you can congure various types of access controls. From this menu, pressing 1 displays the Keypad Lock
Screen that allows you to lock or unlock access to the front panel keypad. Pressing 2 displays the Login/Logout Screen that controls access to certain capabilities based upon the particular user access group to which a user belongs. A third
option, “Setup” will only appear when you are logged into the MPC 128 as “Admin”. It enables the administrator to dene and congure the access capabilities for the various users. Pressing F4 returns you to the Main Menu.
8.5 Keypad Access Control
The rst and simplest part of access control is locking the keypad. This is done simply to prevent someone from bumping into
the MPC 128 keypad and accidentally changing a setting. When the keypad is locked, only the exact key sequence of 857 will allow the user back into the system from the keypad. Keypad lock does not disable any port access in any way.
8.5.1 Keypad Lock
Option 1 in the Access control menu will load the lock keypad screen shown in Figure 40. To get to the Lock keypad screen from the main menu: key sequence 3, 1

8.6 Logging In & Logging Out
A user is automatically logged out when the MPC 128 module is reset, or if the Ethernet socket is closed or broken. Once access control is enabled for a port then a user must login on that port before issuing any commands except those that
are allowed with no login. For the computer interface ports PC Control In, Telnet and Ethernet, the ZI protocol command is used to login. For the Ethernet Telnet console window, any standard Telnet program may be used to bring up a text window with a login prompt.
