NTI VEEMUX DVI VIDEO MATRIX SWITCH
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 49). 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 18 – 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 33), 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:
Note: Models with Video and Audio support will display a “v” or “a” next to the “IN” to indicate which ports connections
are being displayed. When using the keypad, both video and audio connection changes are effected by selections. To
make changes individually to video and audio connections, use eith er the web in terface (page 47) or the optional infrared remote control (page 49).

LCD Menus
Serial Menu
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 8). 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 53).
Ethernet Menu
Under “Ethernet” menu are several parameters:
1- Mode
2- IP Address
3- Mask
4- Gateway
5- Pref. DNS
6- Alt. DNS
The Mode parameter will let you select between a manual IP setting, a DHCP assigned dynamic IP address setting, or disabling
the Ethernet port. 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.

NTI VEEMUX DVI VIDEO MATRIX SWITCH
DDC Menu
DDC enables the video source to get EDID information from the display device. This enables the video source to automatically
select the optimal resolution for the display by receiving, at power up, information from the display device concerning its resolution
specifications.
Under the “DDC” menu are five parameters:
1- Chose Input (Choose Input)
2- All Inputs
3-FacDefault1
4-UsrDefault1
5-ReloadOptn
1) Choose Input- select the EDID information source for each input individually, or
2) All Inputs- select EDID information source for all inputs at once.
Within these sections you will need to select between:
direct- (available in 4x4 and 8x8 models 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
DDC Mix(?)- select which Input will receive EDID information that is common to the Outputs selected on the “DDC Mix”
page (page 42) for that input
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
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.
3) FacDefault1- Select this to use the factory default EDID data for DDC “Default 1” configuration
4) UsrDefault1- Select this to replace the EDID information stored in the VEEMUX for “Default 1” with the EDID data from the
monitor presently connected to Output 1.
5) ReloadOptn- Select this and choose to enable or disable this feature. When enabled, the switch will refresh DDC data
stored in the VEEMUX each time the VEEMUX is power-cycled. The DDC data will be based on the current DDC configuration
settings.
Standby
The fourth option in the main menu is ”Standby”. When Standby is selected, 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 50), or
3) the “Disable Standby” button is pressed in the web interface (page 45)

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 previous 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 provi de 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 49) 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.

USB Console Port
If your VEEMUX is model SM-4X4-DVI(A)-LCD and you have connected a USB cable between the VEEMUX and your PC
(page 6), you will be able to control your VEEMUX serially from a terminal console using this connection.
Installing Drivers
You will only need to install drivers the first time the VEEMUX is connected to your PC. After the first time, when the VEEMUX is
connected your PC should recognize the VEEMUX and re-assign the COM port. Follow the steps below to install the drivers.
1. Make sure the USB cable is connected between the VEEMUX and your PC.
2. Power ON the VEEMUX. The PC will see the VEEMUX as “New Hardware” and create a virtual COM port to communicate with
it.
3. You will be prompted to load drivers. A driver file compatible with Windows XP, 2000, Vista and 7 (32 and 64 bit versions) can
be found on the CD that came with your VEEMUX. Browse to the drive your Product Manual CD is in and locate and select the
file named “veemux_mxn_dvi.inf” in a directory named “windows-drivers\32bit or \64bit” depending upon
your operating system.
The .inf file will direct your PC to locate and install the file usbser.sys (already on your PC, comes with Windows). Installing
the usbser.sys file should happen automatically. When finished, Windows will indicate in stallation is successful.
Windows XP-32 bit Installation
Your typical installation will include windows like the ones that follo w. The images bel ow are from a Windows XP SP2 32 bit
installation.
B. You can try to “Install the software
automatically” but if windows doesn’t check
the CD, you will need to use “Install from a
list or specific location” instead.
. Windows will want to check the internet
for drivers. Choose “No, not this time”
because the drivers are unique to the
VEEMUX.
13
Page 19
NTI VEEMUX DVI VIDEO MATRIX SWITCH
D. Once the driver is installed, you will get
this screen and the VEEMUX USB Console
Port will be ready to use. .
C. Let the New Hardware Wizard search for
the driver, but direct it to the drive the Product
Manual CD is in and the directory of either
the 32 bit driver or the 64 bit driver.
14
Page 20
NTI VEEMUX DVI VIDEO MATRIX SWITCH
D
Windows 7-64 bit Installation
A Windows 7 64 bit installation has a few extra steps. The images below are from a Windows 7, 64-bit installation.
A. Upon VEEMUX power ON, the driver cannot
be found. Press “Close”.
C. From the next window,
select “Browse my
computer for driver
software” .
. In the next window, enter the path to the .inf driver
file (on the Product Manual CD). Press “Next”.
B. Open the Device Manger and select the
VEEMUX in the device list. Right-click and open
“Properties”. Select “Update Driver Software”.
Tip: The Devicer Manager can be opened by
right-clicking on “My Computer” on the
desktop, selecting “Properties”, and
selecting “Device Manager”.
15
Page 21
NTI VEEMUX DVI VIDEO MATRIX SWITCH
E. You will probably get this warning that Windows can’t
verify the publisher of the driver software. Select “Install
this driver software anyway. “
F. The driver will load. This might take a minute while it
searches your computer for the usbser.sys file it needs.
Once it does, you will get a window telling you Windows is
finished. Take note of the COM port number it assigned.
(This one assigned COM3.)
16
Page 22
NTI VEEMUX DVI VIDEO MATRIX SWITCH

4. During the installation, your PC will assign a COM port number to the USB port attached to the VEEMUX. You will need to
identify the COM port number assigned. This information can be viewed in your Device Manager list (below) if you didn’t take
note of it during installation.
COM Port
ssignment
Figure 10- COM port assigned to VEEMUX
Using the USB Console Port
The virtual COM port will be used to enable serial control over the VEEMUX (see RS232 control on page 18). When you open a
terminal program or the Matrix Switcher’s Control Program (page 21), you will need to configure the program to use the correct
COM port (see Figure 10 and Figure 11 ).
Figure 11- Configure COM port in Matrix Switcher's Control Program

NTI VEEMUX DVI 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 20)
• use the Matrix Switcher's Control Program (page 21) provided on the CD
• use the SerTest program (page 22) 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 12).
Baud Rate
The baud rate can be changed by selecting MENU on the front panel ke ypad, using the OSD menu, using Telnet commands
(page 24) or from the RS232 commands (page 20). The baud rate can be set to 115200, 57600, 38400, 19200, 9600, 4 800,
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 12. By setting the appropriate unit address (page 10) , 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 21).
By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the
VEEMUX is interrupted.

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 26). 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:

A <CR> (carriage return, 0x0D) is considered to be the end of the command string. If a string exceeds 16 characters, an end of
string will be inserted automatically to avoid buffer overflow. An eventual <LF> (line feed, new line, 0x0A) after a <CR> will be
ignored. A bad string will always be responded to with the ASCII character ‘?’ followed by a <CR>.
Note: Always be sure to terminate your telnet session with the <X> - <X> - <Enter> command string.

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 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 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 click “Submit”
Step 3- enable scanning sequences and click “Submit”

DDC Options
From the Administration menu, the DDC Options page can be displayed. DDC enables the video source to get EDID information
from the display device. This enables the video source to automatically select the optimal resolution for the display by receiving,
at power up, information from the display device concerning its resolution specifications.
Figure 24- DDC Options page
EDID information can be provided to the video source by the VEEMUX as follows:
Default1- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.
The values for Default 1 support computer monitors.
Default2- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.
The values for Default 2 support televisions.
Load from Output- select the radio button for this option and enter the output number associated with the monitor that the CPU
should get its EDID information from.
Direct- (available in 4x4 and 8x8 models only) The video source on an input will get EDID informati on 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. 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. If output 8 is switched to another video source, the video source on input 1 will then get EDID information
Mixed- The video source on the input port will receive EDID information that is common to the outputs selected on the “DDC Mix”
page (page 42) for that input.
Update DDC setting on Power cycle and on Load Stored Switch Config- place a checkmark in the box to refresh DDC data
stored in the VEEMUX each time the VEEMUX is power-cycled or when a stored configuration (page 33) that includes this DDC
configuration is loaded. The DDC data will be updated based on the configuration on this page.
Save and Store to Switch Configuration 0- press to save the DDC Configuration settings to Switch Configuration 0 so that when
the VEEMUX is power cycled and the “Update DDC setting on Power Cycle….” (above) is checked, the DDC Configurat ion will be
loaded as configured above.
Modify Default1 DDC with User1 DDC- click this button to load the EDID information to “Default1” from the video display
connected to Output 1
Modify Default1 DDC with Factory Default- click this button to restore “Default1” with factory supplied EDID information

1. A Blu-Ray player, and any other video source with protected content, must use "Direct" DDC option and can be
connected to only one output port at a time.
2. In order for the video sources to correctly receive the EDID information from the switch at boot-up, the switch must
be powered-up before all attached video sources.
3. If “Disable Toggle HP” is checked for any Input port, the changes made for that port will not take immediate effect
when “Save” is pressed.
Hot Plug Options
The DVI video standard includes the ability for the DVI monitor to automatically send EDID information to the video source when
the DVI cable is disconnected and re-connected, or “Hot Plugged”.
The DDC Options page includes the option to maintain a “monitor connected” signal to the video source to prevent the source
from going to sleep if the display device is actually disconnected from the VEEMUX. To maintain this signal, place a checkmark in
the box for “Keep HP On” for the associated Input Port (Figure 24).
Under normal circumstances, a PC that is powered-ON without having an active (output with display attached) DVI output port
connection would switch to the default output mode (normally VGA) because the PC would not detect the presence of a DVI
display. This can be avoided by checking “Keep HP On” for that Input port. This allows the switch to signal the PC as if a DVI
display was connected triggering the PC to output video on its DVI output.
The DDC Option page also provides the option to maintain a “monitor connected” signal whe n the VEEMUX is scanning from one
display device to another. Normally the “monitor connected” signal would toggle from On to Off and back to On when the
VEEMUX switches from display device to the next. To prevent this toggling and maintain the signal as On, place a checkmark in
the “Disable Toggle HP” for the associated Input Port (Figure 24).
Note: If the “Disable Toggle HP” is checked for an Input port and the EDID information source for an Inpu t port is
switched from one display or source to another, the Input port will not update the EDID information from the new
display/source.
DDC Mix
From the Administration menu, the DDC Mix page can be displayed. DDC Mix provides a means to decide which output s
(displays) will be used to provide EDID information to the selected input. The VEEMUX will compare EDID information from all
selected outputs and provide EDID information that is common to those displays to the video source. If the “Mixed” option is
desired for an input on the “DDC Options” page (page 41), settings of the DDC Mix for that input (below) should be selected and
saved first.
If the DDC Mix configuration for an input is not configured and the “Mixed” option for the input is selected on the DDC Options
page, a minimal default collection of EDID information will be provided to the video source.
Select the Input port that will receive EDID information
common to the outputs (displays) selected below.
o save time and use the EDID information from the same
outputs for all inputs (video sources), make the output
selections above and then click on “Save For All Inputs”.

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 an d Audio Control” on page 53.
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 number using th e 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.
51
Page 57
NTI VEEMUX DVI VIDEO MATRIX SWITCH
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>)
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-DVI-LCD video matrix switches provide the ability to save and recall up to 10 switch configurations (up to 100 in
the 16X16 and 32X32 models). The switch configurations define the curre nt port connections, volume control settings, and video
blank status. The IRT-UNV IR Remote can be used to access these configurations by using the “SAVE” and “RECALL” buttons.
8x8 Model
To save a configuration, press the “SAVE” button followed by a Numeric key (0-9) corresponding to the memory slot the
configuration is to be saved in. Pressing a single numeric key will immediately force the switch to save the current configuration to
the selected memory slot.
Configurations can be recalled in much the same manner. To recall, press the “RECALL” button followed by the numeric key
corresponding to the memory slot from which the configuration is to be recalled. Pressing a single numeric key will immediately
force the switch to recall the selected configuration.
16x16 and 32x32 Models
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.
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.
Independent Video and Audio Control
For models that support video and audio, the video and audio ports can be independently switched by including in the commands
the Video ( ) or Audio ( ) buttons just prior to the rest of the command. For example:
Connect all speakers to audio input 2
< > + <2> + <IN> + <*>
Connect Video Source Input 1 from Video Output x (any) to Video Output 8:
< > + <1> + <IN> + <8> + <OUT> (must enter the <x> + <OUT> command within 5 seconds of pressing <IN>)
