NTI VEEMUX VIDEO MATRIX SWITCH
39
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.
