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
Supported Web Browsers
Most modern web browsers should be supported. The following browsers have been tested:
• Microsoft Internet Explorer 6.0 or higher

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.

<OUT>, <▼>, Double digit output port number, <▲> increment or <▼> decrement, <ENTER>
Ex 1: <OUT> <
▼> 03 <▲> <▲> <▲> <ENTER>
This will increment the volume by +6dB (2dB/ press).
Ex 2: <OUT> <
▼> 14 <▼> <▼> <ENTER>
This will decrement the volume by -4dB.
• To Mute, use the command:
<OUT>, <▼>, Double digit output port number, the <0> key, <ENTER>
Ex: <OUT> <
▼> 03 0 <ENTER>
This will mute output 3
• To Un-mute, use the instruction:
<OUT>, <▼>, Double digit output port number, the <1> key, <ENTER>
Ex: <OUT> <
▼> 03 1 <ENTER>
This will un-mute output 3
Memory Functions
There are 100 memory locations(0-99) available to save connection configurations. Location 0 is the power-ON default).
• Saving Connections
To save all current connections, use the following command:
<*>, <OUT>, Memory location, <ENTER>
Ex: <*> <OUT> 5 <ENTER>
• Restoring Connections
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.

NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH
I
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.

NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH
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.)
