NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH

INTRODUCTION

The SM-nXm-AV-LCD Audio/Video Matrix switch (VEEMUX-A) allows up to 32 audio/video sources (n) to be connected to up to 16 destinations (m). Different destinations can even be connected to the same source. Video resolution up to 1920x12 00@85Hz is supported with no degradation – guaranteed. Stereo audio is supported, as well as volume control and separate audio/video switching. An LCD on the front panel indicates the current connections. The VEEMUX-A can be controlled by four methods: Front Panel LCD with Keypad, RS232 interface, Ethernet, or optional Infrared Remote.

Basic Operation

The VEEMUX-A allows any source to be connected to any destination at any time with no restrictions or limitations.

• Audio and Video connections can be made concurrently or separately (i.e. user 1 can view video from port 3

and hear audio from port 11).

• Video inputs accept any RGBHV, RGBS, or RGsB signal.

• Video outputs are compatible with any RGBHV or RGBS monitor, regardless of input. (RGsB monitor requires

RGsB input)

• Audio inputs accept any standard line level audio (1Vrms or 2.5Vp-p).

• Audio outputs are capable of driving an 8 Ohm speaker load with 200mW of continuous RMS power.

• The Audio output volume of the AV matrix is adjustable for each output port.

• Up to 15 users (including the administrator) can have controlled WEB interface access to the VEEMUX

CONTROL OPTIONS

The VEEMUX-A Audio/Video Matrix Switch has four methods of control:

• Front Panel LCD with Keypad

• Directly via an RS232 interface

• Remotely via Ethernet

• Infrared Remote (optional)

Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the Infrared Remote option may be requested at the time of the order. The Infrared Remote option requires the purchase of a separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX-A. No software is involved (see page 36 – Infrared Control). With the RS232 or WEB Interface options, there are no external d evices to be purchased. NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 10 – RS232 Control) and a graphic user interface for use with a RS232 or Ethernet connection.

Front Panel LCD with Keypad Control

The front panel keypad and LCD (drawing below) allow the user to view and change current aud io and video connections, adjust audio volume and configure the RS-232 control interface. The keypad buttons perform the following functions.

To restore connections from memory, use the following command: <*>, <IN>, Memory location, <ENTER> Ex: <*> <IN> 5 <ENTER>

Note: If the current switch configuration includes assigned Scan Mode dwell time values (page 9), to save the current configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX-A is powered OFF, all dwell time values will be erased. Also, saving the configuration as memory location 0 will cause it to be the power-ON default configuration.

Configurations that are saved into memory locations via the keypad can be recalled via the web interface (page 20) and vice versa.

Menu Button

The Menu button is used to configure the RS-232 port.

• The baud rate is selected from the “Baud Rate Menu.” To access this menu, use the command: <MENU>, the <1> key

Next, press the keypad number corresponding with the desired baud rate: <1> – 9600 <2> – 4800 <3> – 2400 <4> – 1200

Ex: <MENU> 1 1 This will select 9600 baud

• To set the switch address, use the following instruction: <MENU>, the <2> key, Double digit address (from 01 to 15- the default address is 01)

Ex: <MENU> 2 03 This will set the address at 03

Scan Mode

Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port switching will continue indefinitely and no ports will be skipped, wheth er there are audio or video sources connected to them or not. If desired, the VEEMUX can be configured to skip the scanning of specific ports using the RS232 Command Protocol (page

11) or Telnet (page 14) .

Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting) disables Scan Mode for that output port. If Scan Mode is disabled for a specific port number, then the video or audio to that output port number will only change as decided by the administrator.

Note: While Scan Mode is enabled, audio and video ports of the same number will switch together. Independent control of video and audio ports will be disabled. I.e., when video output 1 switches from input 1 to input 2, audio output 1 will also switch from input 1 to input 2.

To configure Scan Mode from the front panel LCD: Press MENU, the following lines will be displayed:

1) Set Baud Rate

Press MENU again, the following line will be displayed:

Press 3 to select that menu item. The following request will be displayed: Select Port Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time

value for that output and ask for a new value.

Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allo wed (000) but the number should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.

Scan Mode dwell time settings can also be configured through the RS232 Command Protocol (page 11), Telnet commands (page

14), or through the Web Interface (page 22).

NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad Control (page 8). Otherwise when the power is cycled to the VEEMUX-A, all Scan Mode settings will be erased.

TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX-A is powered ON.

2) Set Unit Addr

3) Set Scan Mode

Current Time: 16 New Time:

NOTE: If Outputs Scanning Sequences (page 26) Is enabled, Scan Mode as configured at the LCD front panel will be disabled.

The disabled front panel Scan Mode feature will be indicated by the message “SCAN SEQUENCE

RS232 CONTROL

RS232 enables the VEEMUX to be remotely controlled via RS232. To control the VEEMUX via RS232 the user has three options:

• write a program that runs on a PC using the Command Protocol (page 11)

• use the Matrix Switcher's Control Program (page 13) provided on the CD

• use the SerTest program (page 13) provided on the CD

Remote Connection

The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other controller with an RS232 communications port.

The pin outs for the DB-9 connector on the unit are as follows:

RS232 Connector (DB-9 FEMALE)

PIN SIGNAL FUNCTION

1 None no connection 2 TXD Transmit Data (RXD at host) 3 RXD Receive Data (TXD at host) 4 DSR Data Set Ready 5 GND Signal Ground 6 DTR Data Terminal Ready 7 CTS Clear to Send 8 RTS Request to Send 9 None no connection

On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. T herefore, host handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work for most CPUs. To daisy chain multiple units, use NTI Matrix-Y-1 "Y" cables, except for the last unit connected. (see Fig 6). For a pinout of the Matrix-Y-1 cable, see page 45. For straight through cable pinouts applicable to various terminal types, see page

44.

Baud Rate

The unit powers up with a default baud rate of 9600 and a fixed data protocol of 8 data bits, no parity and 1 stop bit. The baud rate is selectable through the "Baud Rate Menu". A data protocol of 8 data bits, no parity, and 1 stop bit is used in the daisy chain communication.

Unit Address

To allow multiple units to be controlled from a single host port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units using the NTI Matrix-Y-1 "Y" cables. By setting the appropriate unit address with the keypad, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command. (See Fig. 6.)

Autostatus

When Autostatus is enabled, any output-to-input connection change in the VEEMUX-A will cause an Autostatus message to be sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message: pc 01,01:04<CR> which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the administrator. Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 13).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the VEEMUX-A is interrupted.

ETHERNET CONTROL

Telnet Interface-Port 2000

The Telnet Interface enables the user to control the switch using telnet client through an Ethernet connection. The telnet server listens on ports 2000 and 2005. Port 2000 is for an operator telnet session while port 2005 (must be enabled) is intended for a software control type session (see page 16). For operator telnet control using the telnet interface and the current IP address, type the following in a command shell:

telnet 192.168.1.30 2000

The VEEMUX will prompt the user for a password. The user must enter the password followed by <Enter>.

The factory default password is "admin".

With a proper password sent the VEEMUX-A will respond with:

Telnet Interface-Port 2005

For a software control type of telnet interface session (versus operator telnet control through port 2000 as described on page 14), connect to the VEEMUX through the current IP address at port 2005. To do this, a connection to port 2005 must first be enabled (see Web Setup on page 26). Then, with port 2005 enabled, use the command set below to control and acquire information from the VEEMUX.

Notes:

• If Port 2005 connection is idle for 10 seconds it will disconnect

• Up to 2 active connections are allowed at the same time

• After establishing the connection, the unit will answer with *<CR>. If the connection fails or there are already 2

Outputs Scanning Sequences

Figure 19- Outputs Scanning Sequences page

The Outputs Scanning Sequences page (accessible only to the Administrator) displays the configuration of an automatic switching sequence from input (video source) to input for each output (monitor).

The page displays:

 output number being configured  the Scanning Sequence function status for that output  the Scan Mode status of each input (ON/OFF)  the length of time in seconds (dwell time) that each input will be viewed when connected

The output selection at the top of the page can be changed to any output to display the Scan Sequence Input selections and dw ell times for that output.

The inputs and the amount of time that each will be viewed (0-32000 seconds) can be set to cycle sequentially for each connected output. If an input is set to 0 seconds, the sequence status will display “OFF”, and the input will be omitted from the scanning sequence. To include an input in the sequence, enter a dwell time period from 1-32000 seconds, and press Apply.

To quickly clear all dwell time settings, press the Clear All button at the bottom of the page. All sequence settings will chan ge to “OFF” and all dwell time settings will change to 0.

To enable the scanning sequence for the output shown, place a checkmark in the “Sequence Enable” block.

Tip: To quickly enable the scan sequence for multiple outputs, use the “Sequence Enable” blocks found on the Switch Page (page 18).

Note: If only 1 input is set to Sequence “ON”, then the output connection to that input will not change when the Scanning Sequence is enabled.

Note: If the scanning sequence for an output is enabled th rough the web interface, then the Scan Mode for that output

as configured through the LCD menu (page 9) will be disabled.

Page 36

NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH

Example of using Outputs Scanning Sequences Problem: A synchronous scan is desired for all outputs with a dwell time of 30 minutes per input, and no two outputs should be

looking at the same input at any given time. Solution:

1. Set the dwell time for all inputs listed in each output at 180 seconds (30 minutes). Press “Apply”.

2. Go to the Video Switch page (page 18) and set each output to an input of the same number (1 to 1, 2 to 2, 3 to 3, etc..). Click on “Submit” at the bottom of the Video Switch Page to submit selections and establish a connection and starting point for the scanning sequence. (Blocks shown in yellow in the third image indicate connections made.)

3. Click on the “Sequence Enable” box for each output (from the Video Switch Page).

4. Click on “Submit” again to begin the scanning sequence for each output.

From the moment the configuration is submitted, a synchronous scan will begin on all outputs. Each output will connect to its respective input for 30 minutes. After 30 minutes, the outputs will each switch to the next consecutive input and remain connected for 30 minutes. This cycle will continue indefinitely until sequencing is disabled.

Step 1- setup dwell times

Step 4- Click on “Submit” to begin

Step 2- setup starting point for scan and cl ick “Submit”

Step 3- enable the scanning sequence

How To Use The IRT

The IRT-64X32 enables the user to control the connections of up to 32 input ports and 16 output ports on up to four (4) separate NTI audio/video matrix switches. When any key is pressed, the IRT will power ON. A number key should always be pressed first unless a change to the configuration is desired (see "Set Configuration" on page 39). When a number key is pressed the LCD will display that number blinking. What to press next depends on what action is desired;

• change the switch to be controlled

• change the output port

• change the input port

Note: The user must always change or confirm the output port first and the input port second

If the "SYS", "IN" or "OUT" key is pressed first, the LCD will display the current switch followed by the decimal point and an error signal "EE". The error signal will display because there is no number to be displayed. A number key must always be pressed before a "SYS", "IN" or "OUT" key is pressed.

Exception: The "SYS" key is pressed first when setting the configuration. (See page 39)

Power ON with SYS, IN or OUT keys Power ON with "2" key

Change Output Port

Press the desired port number. If there is no change in the desired output port, the output port must still be selected. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.

With the desired port number selected, point the IRT at the switch/receiver and press the "OUT" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. An LED on the receiver will illuminate.

FYI: If the switch did not receive the data the LED will not illuminate. The user can re-send the same data by pressing the "OUT" button again. The LED at the receiver will illuminate to indicate a completed transmission from the IRT..

Note: If the number introduced is larger than the maximum number of outputs the IRT is configured for, then once the "OUT" key is pressed the LCD will display the current switch and the error signal "EE".

Change Input Port

Press the desired port number. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.

With the desired port number selected, point the IRT at the switch/receiver and press the "IN" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. The LED at the receiver will go OFF.

FYI: If the switch did not receive the data the LED will not go OFF. The user can re-send the same data by p ressing the "IN" button again. The illuminated LED on the receiver will go OFF when the received data is complete.

Note: If the number introduced is larger than the maximum number of inputs that the IRT is configured to control, then once the "IN" key is pressed the LCD will display the current switch and the error signal "EE".

Set Configuration

The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting wi ll return to the default value. At the default setting the IRT has the ability control any matrix switch with up to 32 inputs and 16 outputs without changing the configuration. However, when controlling smaller switches without changing the configuration it is up to the user to press valid number(s). To avoid confusion, it is recommended to configure the IRT to communicate with the largest switch to be controlled.

To change the maximum number of inputs or outputs:

1. From power-down state (blank LCD) press and hold the "SYS" button for at least 3 seconds. The LCD will first display an

error message but after 3 seconds the letter "c" will display:

2. Enter the number of inputs or outputs. As the digits are entered, they will be displayed and the last one entered will blink.

Note: Only the inputs OR the outputs may be configured each time the configuration function is used. To perform another configuration operation the user must start again at "Set Configuration" step 1.

3. Accept the choice by pressing the "IN" button for setting inputs, or the "OUT" button for setting the outputs. The LCD will not

blink anymore and will display “i” (for inputs) or "o" (for outputs) and the number.

Notes:

- The maximum nu mb er of inputs and outputs that can be entered is 32 and 16 respectively. If the user introduces a

number larger, the display will show an error signal ("c.EE") and the maximum number will remain at the last valid value configured.

- If more than one switch is being controlled, the IRT should be configured for the largest switch. It is up to the user

to introduce valid numbers to the smaller switches when making selections.

Battery Replacement

The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in the LCD display will illuminate (see illustration below). This will stay illuminated while th e IRT is in use until the batteries are changed or the battery charge is too low for the IRT to operate.

To Change The Batteries:

1. Remove slide cover on rear of unit.

2. Remove old batteries carefully.

3. Insert (2) new “AA” cell batteries.

4. Replace slide cover on unit.

DDC SUPPORT

(Optional)

DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at pow er up, information from the monitor concerning its resolution specifications.

When DDC Support is installed, the DDC information is acquired from the monitor by the VEEMUX-A switch when the VEEMUX-A is powered-up. A monitor with DDC support must be connected to MONITOR 1 for this to occur. The DDC information will be made available at every CPU port.

The DDC information can also be acquired by pressing the DDC button located on th e front of the switch. This button allows the monitor configuration to be changed without powering down the switch.

Notes:

1. All monitors connected to the VEEMUX-A switch with DDC support must be able to support at least the maximum resolution of the DDC monitor connected to '"MONITOR 1".

2. In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch must be powered up before all attached CPUs.

RS232 UPGRADE OF THE FRONT PANEL LCD FIRMWARE

The firmware in the front panel LCD can be upgraded to include the latest features availabl e using either the RS232 port (below) or Ethernet Control (page 22). Follow the procedure below to use the RS232 method to u pdate the Front Panel LCD firmware in the VEEMUX-A. To prepare, first download the rmtlcd_va_1_x. hex file (x= the current firmware version) from the NTI Video Matrix Switch website http://www.networktechinc.com/vmtx.html

The following will be needed:

1 PC running HyperTerminal (or other terminal program) equipped with a 9 pin or 25 pin serial port

o o A VEEMUX-A made to use the Firmware Upgrade feature o 1 serial cable wired straight through to connect your PC's serial port to the “RS232” port on the VEEMUX-A

(see cable specifications on page 44)

o A firmware file for a VEEMUX-A downloaded from www.networktechinc.com

Procedure:

1. Power OFF the VEEMUX-A.

2. Connect the null modem cable between the serial port on the PC and the “RS232” port on the VEEMUX-A.

3. Use HyperTerminal to prepare to connect to the VEEMUX-A (using settings 9600 baud, 8-N-1 no flow). Make sure HyperTerminal has been configured for connection through the correct COM port on the PC.

4. With the HyperTerminal window open, hold the spacebar and apply power to the VEEMUX-A. A command menu and the Command prompt (>) should appear.

C Clear flash

L Load flash with .hex file

Command>

Note: Commands are not case-sensitive (for example, 'h' or 'H' will execute the help command), and the <Enter> key is not required to execute a command.

If the Flash Loader Utility menu does not appear, the VEEMUX-A you have may have been made prior to the release of this product change. To verify this, with the VEEMUX-A powered ON, at the HyperTerminal window enter the following command:

RV 01 (be sure to include the space)

The following revision string will appear:

$date: 2006/04/17

If the date shown is before

20:20:59 $$revision: 1.1 $$IN: 08 $$OUT: 04 $

2006/04/17, then the VEEMUX-A firmware cannot be upgraded using this procedure.
