INTRODUCTION
The SM-nXm-15V-LC (n = number of inputs (video sources), m = number of outputs (monitors)) video matrix switch (VEEMUX)
allows any of up to 8 video sources to output to any or all of up 8 (8) monitors. The configuration of the VEEMUX is determined
at time of order. The bandwidth of the SM-nXm-15V-LC is 160MHz and video resolutions through 1920 x1200 are supported with
no degradation. The switch can be controlled with the Front Panel Keypad, RS232 interface, Ethernet, or an 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. Built-in infrared control 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.
Ordering Information
The SM-nXm-15V-LC is built to a specific size ranging from 2, 4 or 8 monitors and 4 to 8 video sources. The “n” in the part
number represents the number of video sources. Select a switch built for 4 or 8 video sources. The “m” in the part number
represents the number of outputs (monitors). A switch built for 2, 4 or 8 monitors may be ordered. It is not necessary to fully
populate all of the connectors on the unit (ex. an SM-8x8 switch has the capability of supporting 8 video sources and 8 monitors,
but it will operate with only 4 video sources with 2 monitors connected.

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
Infrared Remote.
Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Infrared Receiver built in. 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 10 – 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 Precedes the output number
IN Used following single digit output entries
ENTER Used following single digit entries and
to select menu options
Display next 4 outputs and their inputs
Display previous 4 outputs and their inputs
MENU See below for description of the Menu.
* Connects all outputs to one input (i.e. To set all outputs to one input ( * ) + (Input # ) + (ENTER) )
To configure the VEEMUX, use the Menu keys.
Press the List button to list your main menu options:
1- Serial
2- Ethernet
3- Standby
4- Save Config
5- Load Config
Use the Up and Down Arrow keys to scroll through this list.

LCD Menus
1. Under the “Serial” menu are two parameters:
1- Baud rate
2- Address
These parameters are used when the VEEMUX is controlled through an RS232 connection (page 10). If you select Baud rate,
use the arrow keys to toggle through the available baud rates. The baud rate can be set to 115200, 57600, 38400, 19200, 9600,
4800, 2400, or 1200.
If you select Address, use the arrow keys to toggle through the address options (01-15). This is also the switch address used in
conjunction with the IR Remote operation (page 39).
2. Under “Ethernet” menu are several parameters:
1- Mode
2- IP
3- Mask
4- Gateway
5- Primary DNS
6- Alt. DNS
The Mode parameter will let you select between a manual IP setting (“Static”) and a “DHCP” assigned dynamic IP address setting.
An asterisk indicates which mode is configured, an arrow shows which mode is being selected. To change the configured setting
and move the asterisk, select the desired mode and press the Enter button.
If you choose a manual IP setting, the IP parameter provides the fields for entering a valid IP address. Use the up and down
arrows to advance the numbers, and the Enter button to move from field to field. Press Menu to exit this screen.
Selections 3, 4 are necessary to apply valid values for your Subnet Mask and Gateway. Navigate these settings as described for
setting the IP address.
Selections 5 and 6 are not used at this time and are therefore unnecessary.
3. The third option in the main menu is ”Standby”. If you select Standby, the VEEMUX switch will immediately go into a power
saver mode and the LCD display will go blank. It will remain in this state until
1) any button is pressed on the front panel,
2) the Standby button is pressed on the IR Remote Control (page 36), or
3) the “Disable Standby” button is pressed in the web interface (page 32)
Save and Load (Recall) Config
The VEEMUX provides the ability to save and recall up to 100 switch configurations using the LCD menu. The switch
configurations define the current port connections and video blank status.
Note: The Remote Control can also be used to access these configurations by using the “SAVE” and “RECALL”
buttons.
To save a configuration, select “Save Config” from the main menu followed by a numeric button(s) (0-99) corresponding to
the memory slot the configuration is to be saved in. Press Enter after your selection to force the current configuration to
immediately be saved to the selected memory slot.
Configurations can be loaded (recalled) in much the same manner. To recall, select “Load Config” from the main menu
followed by the numeric button(s) (0-99) corresponding to the memory slot from which the configuration is to be recalled. Press
Enter after your selection to immediately force the switch to change the current switch configuration to match that of the
configuration recalled.
Configurations that are saved into memory locations via
the keypad can be recalled via the web interface (page 22)
and vice versa.

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 12)
use the NTI Switch Control Program (page 13) downloaded from http://www.networktechinc.com/download/d-
vmtx.html
use the SerTest program (page 14) provided with the NTI Switch Control Program download
Remote Connection
The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an
RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:
RS232 (RJ45) CONNECTOR
PIN SIGNAL FUNCTION
1 - No connection
2 - No connection
3 RX+ Receive data (TXD at host)
4 GND Ground
5 - No connection
6 TX+ Transmit data (RXD at host)
7 - No connection
8 - No connection
A 5 foot patch cable and adapter, RJ45-to-DB9, have been provided for connection to most CPUs (see page 6). To daisy chain
multiple units, connect a Matrix-Y-1 cable (sold separately) between the CPU and the first switch, and between each switch (as
shown in Figure 8).
Baud Rate
The baud rate can be changed by selecting MENU on the front panel keypad, using Telnet commands (page 16) or from the
RS232 commands (page 12). The baud rate can be set to 115200, 57600, 38400, 19200, 9600, 4800, 2400, or 1200. A data
protocol of 8 data bits, no parity, and 1 stop bit is used for communications. The default baud rate setting is 9600.
Unit Address and Loop Back
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 an NTI Matrix-Y-1 cable. Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter (provided with
the RS232 option) and the CPU as shown in Figure 8. By setting the appropriate unit address (page 9), 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.

Command
String Good Response Description
Gs SW,OP *<CR>DWT<CR> Read scan mode dwell time setting for an Output port
DWT values: 000-255 000= scan is disabled for the port
Sa SW,OP *<CR> Set scan list of individual output to all inputs
Sc SW,OP *<CR> Clear scan list of individual output
S+ SW,OP,IP *<CR> Add individual input to Scan List of output
S- SW,OP,IP *<CR> Remove individual input from Scan List of output
Sx SW,OP *<CR>oooxoxxxooooxxx<
CR> Inspect the Scan List of individual output (o=skip x=don't skip)
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 NTI Switch 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 (must be enabled-see page 26) while port 2005 is
intended for a software control type session (see page 17). 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 "nti".
With a proper password sent the VEEMUX will respond with:
