NTI VEEMUX VIDEO MATRIX SWITCH

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.

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

• 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 equa l 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.
Use the Enter Key to select a menu item.
Press the Menu button again to exit the menu.

If, while in a menu, you pause for more than 5 seconds, you will automatically exit the menu.

NTI VEEMUX VIDEO MATRIX SWITCH

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 1 0). 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, 19 200, 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” fro m 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.

NTI VEEMUX 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 12)

• use the NTI Switch Control Program (page 13) 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 ke ypad, 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, 24 00, 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 ad dress (pa ge 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.

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:

output. If an input is set to 0 seconds, that input will not be viewed and will be skipped from the scanning sequence. To include
an input in the sequence, enter a dwell time period from 1-255 seconds, and press “Save”.

If you make changes and change your mind and want to return the values back to what they were before changing them, press
“Reset”. This must be done before pressing the “Save” button, or changes will not be able to be reversed.

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

Tip: To quickly enable the scan sequence for multiple outputs, use the “Sequence Enable” blocks found on the Switch
Page (page 29).

Note: If only one input has a dwell time value entered, then the output connection to that input will not end when the
Scanning Sequence is enabled.

NTI VEEMUX VIDEO MATRIX SWITCH

Example of using Outputs Scanning Sequences
Problem: A synchronous scan is desired for all outputs with a dwell time of 3 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 (3 minutes). Press “Save” each time changes are
made to the selected output. .

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 scan ni ng 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 3 minutes. After 3 minutes, the outputs will each switch to the next consecutive input and remain connected
for 3 minutes. This cycle will continue indefinitely until sequencing is disabled.

Step 4- Click on “Submit” to begin

Step 1- setup dwell times

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

Step 3- enable scanning sequences and click “Submit”

Operation

Operation of the IRT-UNV is intuitive. The number of button presses required to complete any operation is kept to a
minimum. This is accomplished using intelligent soft ware within the NTI Matrix Switch. Additionally, the Matrix Switch allows for
multiple ways for the user to complete the same operation – ensuring th at the Remote will work as expected, regardless of who
uses it.

Note: For models with audio support, these commands will switch the video and audio signals simultaneously. For
independent video and audio switching using the IRT-UNV, see “Independent Video and Audio Control” on page Error!
Bookmark not defined..

Changing Ports

The first, and most important operational use of the IR Remote is changing ports of the switch. This requires the

selection of both input and output ports. There are several methods of control.

Channel Surfing

The “IN +/-“ and “SCAN” buttons can be used to surf through input p ort connections. However, since there are multiple
outputs/users, the question becomes “which output connection is being changed?” As a re sult, it is required that an output be
selected prior to using the “IN +/-“ buttons.

The output port can be selected in two ways:

• by pressing the “OUT” button before selecting the output port number

• by pressing the “OUT” button after selecting the output port number

In both cases, the user must enter the output port num ber using the Numeric Keys (0-9). However, when the “OUT”
button is pressed prior to selecting the port number, there will be a t wo (2) second delay after the last digit of the output port is
entered that must expire before the output port is accepted. To avoid this del ay, press the “ENTER” but ton to immediately accep t
the port number.

Once the output port has been accepted, there will be a five (5) second timeout, during which the user must press
another button (“IN +,” IN -,” or “SCAN”). Each subsequent press of “IN+” or “IN-“ will rene w the timeout, waiting for yo u to press it
again (to advance or go back by one more I nput channel). If no new command is sent t o the switch before the timeout expires,
the switch will forget the selected output, and pressing the “IN +/-“ buttons will have no effect.

All output channels can surf inputs at once by pressing the “ * “ button prior to pressing the “IN +/-“ buttons.

Examples:

Change connection of Output 1 from Input 1 to Input 3:

<OUT> + <1> + wait 2 seconds + <IN+> + <IN+>

<OUT> + <1> + <ENTER> + <IN+> + <IN+> (must press <IN+> within 5 seconds of pressing <ENTER>)

<1> + <OUT> + <IN+> + <IN+> (must press <IN+> within 5 seconds of pressing <OUT>)

37

NTI VEEMUX VIDEO MATRIX SWITCH

Jump To Input

With the output port selected, a user knowing the desired i nput port number can enter it using the Numeric ke ys (0-9).
Just as with using the “OUT” button, pressing the “IN” but ton after the number will force the command immediately. If the “IN”
button is pressed prior to the port number, the “ENTER” button must be pressed to avoid a two (2) second delay before the in put
port is accepted.

Examples:

Quick method to change Output 1 from Input x (any) to Input 8:

<1> + <OUT> + <8> + <IN>

Quick method to change Output 12 from Input x (any) to Input 20:

<1> + <2> + <OUT> + <2> + <0> + <IN>

Jump To Output

Users can also change ports by specifying the input port number first. Similar to selecting the output port first, the “IN”
button can be pressed either before or after entering the port number. Once the input port has been selected, the output port can
be selected, following the same format as “Jump to Input…”

Expiration of a five (5) second timeout will force the switch to forget the entered input port number.

Example:

Quick method to change Input 1 from Output x (any) to Output 8:

<1> + <IN> + <8> + <OUT> (must enter the <x> + <OUT> command within 5 seconds of pressing <IN>)

Connect All

It may be desirable to broadcast the video (and audio) signals from one input to all of the outputs. In this situation, the
user can quickly make all of these connections by using the “ * ” (asterisk) button which selects all outputs. With the input port
selected, pressing the “ * “ button will immediately force the command to connect all output ports to the selected input.

Example :

Connect all users to Input 2:

<2> + <IN> + <*>

The “ * “ button can also be pressed prior to selecting the input port. In this case, the command will take effect once the

input port has been selected.

<*> + <2> + <IN>

If no command is received before the five (5) second timeout expires, the switch will forget the “ * “ key-press.

Save and Recall

The SM-8X8-LC-LCD video matrix switches provi de the ability to save a nd recall up to 10 switch configurati ons. The switch
configurations define the current port connections and vide o blank status. The IRT -UNV IR Remote can be used to ac cess these
configurations by using the “SAVE” and “RECALL” buttons.

To save a configuration, press the “SAVE” button followed by Numeric key(s) 0-99 corresponding t o the memory slot the
configuration is to be saved in. After the numeric key(s) press the “Enter” button. If the “Enter” button i s not pressed, after two
seconds the function will timeout and the number entered will be saved as that configuration.

Configurations can be recalled in much the same manner. To recall, press the “RECALL” button followed by the numeric key
(s) corresponding to the memory slot from which the configuration is to be recalled. After the numeric key(s) press the “Enter”
button. If the “Enter” button is not pressed, after two seconds the function will timeout and the number entered will be recalled to
the current configuration.

NTI VEEMUX VIDEO MATRIX SWITCH

Multiple Switch Control

All compatible NTI matrix switches will work with the sam e I RT -UNV IR Re mote co ntrol. As a res ult, a u ser with multiple NTI
matrix switches may find that, if the switches are installed too close together, both switches may respond to an IR command
intended only for one switch. Or, the user may want to control multiple switches with a single remote, instead of having one
remote per switch. To accommodate this situation, the IRT-UNV IR Remote provides the “SYS” but ton, which can be used to
select the NTI switch to be controlled.

All switches will have the capability to allo w the user to set the switch address (0-15). Each switch to be separately controlled
must be set to a different address prior to using the Remote Control. With the addresses set, press the “SYS” button on the IRT­UNV, followed by a two digit number corresponding to the address of the matrix switch to be controlled.

Upon accepting the “SYS” command, the switch with the corresponding address will illu minate the “IR” LED and respond to
all IR Remote commands and will blink the “IR” LED on the front of the switch for visual indicatio n. All other switches will ignore
any further commands, until the “SYS” button is pressed again. To select a new NTI switch to control, press the “SYS” button
again and repeat the process.

Canceling a Command

Considering the number of key presses required for some of the commands, it’s possible that the us er may inadvertently
press an incorrect button. Should this happen, the user can press the “ESC” button to cancel a command. Provid ed the command
has not been accepted by the system, pressing the “ESC” button will caus e the switch to “forget” or “erase” all button commands
from the current command sequence. Once the command sequence has been cancelled, the user can begin entering the
command again.
