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:

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 either the web interface (page 47) or the optional infrared remote control (page 49).

To quickly 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 Outx button or the Inx button is pressed first doesn’t make a difference.

To configure the VEEMUX, use the Menu keys.

Press the List button to list your main menu options:

1- Serial

2- Ethernet

3- DDC

4- Standby

5- Save Config

6- 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 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.

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 18). 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 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.

10


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 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.

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 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 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” 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.

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 installation is successful.

Windows XP-32 bit Installation

Your typical installation will include windows like the ones that follow. The images below are from a Windows XP SP2 32 bit installation.

A. Windows will want to check the internet for drivers. Choose “ No, not this time ” because the drivers are unique to the

VEEMUX.

B. You can try to “ automatically

Install the software

” but if windows doesn’t check the CD, you will need to use “ list or specific location

Install from a

” instead.

13


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


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” .

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”.

D. In the next window, enter the path to the .inf driver file (on the Product Manual CD). Press “Next”.

15


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


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

Assignment

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

17


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 -

2 -

3 RX+ Receive data (TXD at host)

4 GND Ground

5 -

6 TX+

7 -

Transmit data (RXD at host)

8 -

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 keypad, 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, 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 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.

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 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:

Password Successful

Scanning Sequence is enabled.

38


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 1- setup dwell times

Step 4- Click on “Submit” to begin

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

Step 3- enable scanning sequences and click “Submit”

39

Figure 23- User configuration page

After making any changes, be sure to click “Save”.

40


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 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. 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 from output 2.

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 Configuration 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

Once any changes are made, press “ Save ” to have them take effect.

41


Notes:

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 when 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 Input 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 outputs

(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.

To 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”.

Figure 25- DDC Mix page

Video Optimization

(Applicable to models 4x4, 16x16, and 32x32 only) From the Administration menu, the Video Optimization page can be displayed. This page enables the administrator to improve the video quality of a PC (input) as viewed on a monitor (output).

Note: It is not recommended that the user change the video quality of a connection while in the web interface on that connection. Changing the

Optimize Video values of the connection while in the web interface could result in a loss of video on that monitor and the inability to complete the task without logging into the

VEEMUX from another PC.

Figure 26- Video Optimization page

If video quality is poor, press the left arrow or right arrow adjacent to the corresponding connection to increase or decrease the video quality value (default is 27).

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 software within the NTI Matrix Switch. Additionally, the Matrix Switch allows for multiple ways for the user to complete the same operation – ensuring that 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 53.

Changing Ports

The first, and most important operational use of the IR Remote is changing ports of the switch. This requires th e 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 port connections. However, since there are multiple outputs/users, the question becomes “which output connection is being changed?” As a result, 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 the Numeric Keys (0-9). However, when the “OUT” button is pressed prior to selecting the port number, there will be a two (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 delay, press the “ENTER” button to immediately accept 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 renew the timeout, waiting for you to press it again (to advance or go back by one more Input channel). If no new command is sent to 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


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 input port number can enter it using the Numeric keys (0-9).

Just as with using the “OUT” button, pressing the “IN” button 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 input 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 16X16 and 32X32 models). The switch configurations define the current 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.

The SM-8X8-DVI-LCD video matrix switches provide the ability to save and recall up to 10 switch configurations (up to 100 in

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 to the memory slot the configuration is to be saved in. 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 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 same IRT-UNV IR Remote control. As a result, a user 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” button, which can be used to select the NTI switch to be controlled.

All switches will have the capability to allow 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 IRT-

UNV, 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 illuminate the “IR” LED and respond to all IR Remote commands and will blink the “IR” LED on the front of the switch for visual indication. 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 user may inadvertently press an incorrect button. Should this happen, the user can press the “ESC” button to cancel a command. Provided the command has not been accepted by the system, pressing the “ESC” button will cause 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>)
