INSTALLATION
This NTI switch was designed to be mounted to a rack or to set on a desktop. It includes rack mount ears to make attachment to
a rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat
surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.
To Mount to a Rack
1. (For SM-8X8-DVI-LCD, otherwise skip to step 2) Attach the ears to the switch using the #6-32x3/16" flat Phillips-head
screws (6) provided as shown in the illustration below. The holes in the ears should line up with pre-threaded holes in the
sides of the NTI switch. Tighten the screws securely.
Figure 1- Secure rack mount ears to switch
2. Install 4 cage nuts (supplied) to the rack in locations that line up with the holes in the mounting ear on the NTI switch.
3. Secure the NTI switch to the rack using four #10-32X3/4” screws (supplied). Each screw should be of sufficient length
to go completely through the NTI mounting ear, rack frame and fully engage all threads in the cage nut. Be sure to
tighten all mounting screws securely.
4. Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.

OPERATING THE VEEMUX
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 (optional).
Every unit comes standard with all control methods built-in. An IRT-UNV-IR Remote Control is required (purchased separately)
to use the Infrared option. No software is involved (see Infrared Control on page 36). 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 11 – 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 first 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.). (After configurations have been saved (page 23), upon power-up
the VEEMUX will load the configuration saved into memory location 0.) Along with the routing of the inputs (video sources) to the
outputs (monitors) the keypad and LCD allow the users to configure the RS232 control interface. The keypad buttons perform the
following functions:
Model SM-8X8-DVI-LCD
Key Functions:
Up Arrow- Scroll up the menu
Down Arrow- Scroll down the menu
Left Arrow (Enter Key)- Select the menu item
List - Open the menu, or exit the menu (also used to back
out of the menu, one step at a time)
Out-1- through 8 Used in command sequence to select which
output (display device) to connect
In-1-though 8 Used in command sequence to select which
input (video source) to connect
To change a connection, simply press an Out number followed by an In number corresponding to the display device you want
to connect to the video source. Whether the Out-xbutton or the In-xbutton is pressed first doesn’t make a difference.
To configure the VEEMUX, use the Menu keys.

Use the Up and Down Arrow keys to scroll through this list.
Use the Enter Key to select a menu item.
Press the List button again to exit the menu. If, while in a menu, you pause for more than 5 seconds, you will automatically exit
the menu.
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 11). 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 40).
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 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 List 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. Under the “DDC” menu are two parameters:
1- Chose Input (Choose Input)
2- All Inputs
You can either 1) select the EDID information source for each input individually, or 2) for all inputs at once. Within this section
you will need to select between:
direct- (available in 8x8 model only) the video source on an input will get EDID information from the video display device
that is first connected to the output, regardless of what other display devices are also connected to the video source
default 1- the inputs will get EDID information from a predefined table in the VEEMUX supporting CPU monitors
default 2- the inputs will get EDID information from a predefined table in the VEEMUX supporting televisions
From Out (?)- select which Output port the Input will get EDID information from regardless of which output it is
connected to
More on “Direct” DDC: If the first output is switched to another input, the video source will look to the other connected
outputs to get EDID information from, searching from the lowest numbered output port first.
For example: The video source on input 1 is connected to output 8, then 4, then 2, and then 5 for a total of 4
display connections. The video source gets it EDID from output 8, the first connected output. If output 8 is
switched to another video source, the video source on input 1 will then get EDID information from output 2.

4. The fourth 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 optional IR Remote Control (page 37), or
3) the “Disable Standby” button is pressed in the web interface (page 33)
Models SM-16X16-DVI-LCD and SM-32X32-DVI-LCD
The keypad control for the 16X16 and 32X32 models is very similar to that of the 8X8, with these differences:
•The “In” and “Out” ports are selected by pressing the associated port number and then the “In” or “Out” button to
designate the video source or the display (respectively). Alternatively, the “In” or “Out” button can be pressed, then
the port number, followed by the “Enter” button.
•Multiple displays can be connected to a single video source using one command sequence:
<In> xx<Out>xx<Out>xx<Out>xx<Out>xx<Enter> or
<Out>xx<Out>xx<Out>xx<Out>xx <In> xx <Enter> (where xx is the port number)
•Within the “DDC” menu, “Default 1”, “default 2”, and “From Out (?) will work as described on the pevious page,
however the “direct” option is not applicable.
•The main menu has two additional options, 5-Save Config and 6-Load Config, described below
•The list of current connections shown on the LCD screen can be scrolled using the Up and Down Arrows, rather than
waiting for them to show the connection you are looking for.
Save and Load (Recall) Config
The SM-16X16-DVI-LCD and SM-32X32-DVI-LCD switches provide the ability to save and recall up to 100 switch
configurations using the LCD menu. The switch configurations define the current port connections, volume control settings, and
video blank status.
Note: The IRT-UNV IR Remote (page 36) 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.

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 13)
•use the Matrix Switcher's Control Program (page 14) provided on the CD
•use the SerTest program (page 14) provided on the CD
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 the OSD menu, using Telnet commands
(page 16) or from the RS232 commands (page 13). 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.

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 (page 14).
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 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:
Password Successful
Connection Established
