NTI VEEMUX VIDEO MATRIX SWITCH
INTRODUCTION
The SM-nXm-15V-LCD (n = number of inputs (video sources), m = number of outputs (monitors)) video matrix switch (VEEMUX)
allows any of up to 32 video sources to output to any or all of up to sixteen (16) monitors. The configuration of the VEEMUX is
determined at time of order (i.e. 16x4, 8x16, etc.). The bandwidth of the SM-nXm-15V-LCD is 200MHz and video resolutions
through 1900 x1200 are supported with no degradation. The switch can be controlled with the Front Panel Keypad, RS232
interface, Ethernet, or an optional Infrared Remote.
The VEEMUX can be ordered in many sizes and with several control options. The base unit includes a user keypad, an RS232
port, and an Ethernet port to make up a complete system. The infrared option, purchased separately, allows for maximum user
satisfaction in each unique configuration.
Basic Operation
The VEEMUX allows any source to be connected to any destination at any time with no restrictions or limitations.
• 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)
Supported Web Browsers
Most modern web browsers should be supported. The following browsers have been tested:
• Microsoft Internet Explorer 6.0 or higher
• Netscape 7.0 or higher
• Mozilla FireFox 0.9.2 or higher
Set your browser to always check if there is a newer version of the page than the version stored in cache. This action will ensure
that it will display the most up-to-date information.
Compatibilty
The SM-nXm-15V-LCD is made to support video inputs from VGA (15HD – H & V Sync) only.
Ordering Information
The SM-nXm-15V-LCD is built to a specific size ranging from 2, 4, 8, 12, or 16 monitors and 4 to 32 video sources. The “n” in the
part number represents the number of video sources. Select a switch built for 4, 8, 16, or 32 video sources. The “m” in the part
number represents the number of outputs (monitors). A switch built for 2, 4, 8, 12, or 16 monitors may be ordered. It is not
necessary to fully populate all of the connectors on the unit (ex. an SM-16x8 switch has the capability of supporting 16 video
sources and 8 monitors, but it will operate with only 14 video sources with 7 monitors connected.

Power Up
1. Plug the VEEMUX into an AC power outlet.
2. Turn ON power to the VEEMUX.
3. Turn ON power to the video sources and monitors connected to the VEEMUX.
LED MATRIX
(not available on all models)
The LED Matrix is a grid of LEDs on the front panel of the VEEMUX. This grid is used to provide a visual indication of all
connections between video sources and destinations. To determine if an input (video source) is connected to an output (video
destination), follow the LEDs down and to the right (respectively) until they intersect. The illuminated LED at the point of
intersection indicates the input is connected to the output by the VEEMUX.

NTI VEEMUX VIDEO MATRIX SWITCH
CONTROL OPTIONS
The VEEMUX video matrix switch has four methods of control:
• Front Panel LCD with Keypad
• Directly via an RS232 Interface
• Remotely via Ethernet (rack mount models only)
• Infrared Remote (optional).
Every unit comes standard with the Front Panel LCD with Keypad, and RS232 built in. Rack mount models also include Ethernet
connection. If desired, the Infrared option must be requested at the time of the order. The Infrared option requires the purchase
of a separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX. No
software is involved (see Infrared Control on page 23). With the RS232 option, there are no external devices to be purchased.
NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 8 – RS232
Control).
Front Panel LCD with Keypad Control
The front panel LCD and keypad allow the user to monitor switch status and route any user to any video source on the switch.
When the unit is powered up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to
source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). Along with the routing of the inputs (video sources) to the outputs
(monitors) the keypad and LCD allow the users to configure the RS-232 control interface. The keypad buttons perform the
following functions.
ESC Escape back to the main display.
0 – 9 Used to enter numbers. ( # )
OUT The output user number can be entered
(2 digits or 1 digit and ENTER or IN)
OUT: 1 2 3 4
IN: 1 2 3 4
ESC

MENU The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 2400, 1200 or 300 baud and the unit
address to be set to 1 - 15. See RS-232 control later in this chapter.

to Save current connections ( * ) ( OUT ) ( # ) ( ENTER )
to Recall connections from ( * ) ( IN ) ( # ) ( ENTER )
To set all outputs to one input ( * ) + ( # ) + (ENTER)
The following examples show various method of routing output 3 to input 5. Inputs and Outputs can be entered as a two digit
number or a one digit number followed by IN or ENTER.
(OUT) 3 (IN) 5 (ENTER)
(OUT) 3 (ENTER) 5 (ENTER)

Note: If the current switch configuration includes assigned Scan Mode dwell time values (pg. 8), to save the current
configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX 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.

NTI VEEMUX VIDEO MATRIX SWITCH
Scan Mode
Scan Mode causes an output port to automatically switch from one input port to the next consecutive input port after a specified
period of time (referred to as the dwell time). Port switching will continue indefinitely and no ports will be skipped, whether there
are 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 9) or Telnet (page 13).
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, then the video to that output will only
change as decided by the administrator.
To configure Scan Mode from the front panel LCD:
Press MENU, the following lines will be displayed:
1) Set Baud Rate
2) Set Unit Addr
Press MENU again, the following line will be displayed:
3) Set Scan Mode
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.
Current Time: 16
New Time:
Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (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 settings can also be configured through the RS232 Command Protocol (page 9), Telnet commands (page 13), or
through the Web Interface (page 17).
NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad
Control (page 7). Otherwise when the power is cycled to the VEEMUX, 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 is powered
ON.
NOTE: If Outputs Scanning Sequences (page 21)
Is enabled, Scan Mode as configured at the LCD
front panel will be disabled.
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 9)
• use the Matrix Switcher's Control Program (page 11) provided on the CD
• use the SerTest program (page 11) 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. There is, however, a restriction that must be followed:
The pin outs for the DB-9 connector on the unit are as follows:
RS232 Connector (DB-9 FEMALE)
PIN SIGNAL FUNCTION PIN SIGNAL FUNCTION
1
None no connection
2 TXD Transmit Data (RXD at host) 7 CTS Clear to Send
3 RXD Receive Data (TXD at host) 8 RTS Request to Send
4 DSR Data Set Ready 9
5 GND Signal Ground
6 DTR Data Terminal Ready
none no connection
8
Page 13
NTI VEEMUX VIDEO MATRIX SWITCH
On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. Therefore, 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 32. For straight through cable pinouts applicable to various terminal types, see page

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 can be changed by pressing the MENU button on the front panel keypad. Then select 1 for SET BAUD RATE and select the
desired baud rate of 9600, 2400, 1200 or 300. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.
Unit Address
To allow multiple units to be controlled from a single CPU 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 (the default address is
01), 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.
To set the unit address:
-select MENU on the front panel keypad
-select 2 for SET UNIT ADDRESS
-press the address number (1-15)
- press ENTER.

Command Protocol
CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the
command definitions table below. All characters in the command string should be upper case, and all numbers below 10 should
have a leading 0 (ex: 1 = 01). As command strings are sent, the inner character delay cannot exceed 500 milliseconds.
Note: To use this command protocol, the user is required to write a program that will send an entire command string all
at once, not character by character. Programs that send one character at a time (such as HyperTerminal) cannot be used
to control the VEEMUX. Alternatively, the user may use the Matrix Switcher's Control Program or SerTest to control the
VEEMUX via RS232 (see page 11).

If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch
memory, the command will be ignored. If the SW field corresponds to the unit address, but the syntax is wrong after this field, the
switch will answer with a bad response ?<CR>.
Autostatus
When Autostatus is enabled, any output-to-input connection change in the VEEMUX 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 (below).
By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the
VEEMUX 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 21). 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 will respond with:

Outputs Scanning Sequences
Figure 14- Outputs Scanning Sequences page
The Outputs Scanning Sequences page 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
21
Page 26
NTI VEEMUX VIDEO MATRIX SWITCH
The output selection at the top of the page can be changed to any output to display the Scan Sequence Input selections and dwell
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 change 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 through the web interface, then the Scan Mode for that output
as configured through the LCD menu (page 8) will be disabled.
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 click “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 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 30). 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 30)
Power ON with SYS, IN or OUT keys Power ON with "2" key
Change the Switch
Press the number of the switch to be controlled. The number selected will be blinking in the last digit.
FYI: If the user realizes that an invalid number has been introduced before
buttons, a correction can be made by pressing the correct number. If the correct number is a single digit, it must be
preceded by a "0" to make the correction.
Press the "SYS" key. The blinking number will become blank and the switch number will update.
Note: If the number entered is larger than 4, when the "SYS" key is pressed the LCD will display the current switch and
the error signal "EE".

pressing either the "SYS", "IN", or "OUT"
Page 33
NTI VEEMUX VIDEO MATRIX SWITCH
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 pressing 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".

Page 34
NTI VEEMUX VIDEO MATRIX SWITCH
Set Configuration
The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting will 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 number 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 the 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 power 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 the 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.

Grounding
These products have protective earth ground terminals and are built with full attention to consumer safety. There must be an uninterruptible safety earth ground between the main power source and the product's power cord or supplied power cord set.
If ever the possibility exists for the grounding protection to have been reduced in any way, disconnect the power supply until the
grounding connection has been fully restored.
