Pair Settings
The XRTx provides several options for using the 4
th
-pair signals (pairs 1-3 are generally used for video). Note
that any connected MultiView™ or MultiView™ II receiver must be configured with a matching 4
th
-pair operating
mode. Otherwise, the desired 4
th
-pair signal will not work as expected.
If an optional daughterboard is installed (232, SA or SAP options), then the 4
th
-pair
utilization is defined by the installed daughterboard. It will not be possible to change any of
the 4
th
-pair settings as described below.
Perform the procedure below while the transmitter is in the normal operating state (CFG indicator is off):
1. Press and release the CFG button once to access configuration-mode (CFG indicator = on).
2. Press and release the SEL button twice. You will now be able to change 4
th
-pair option settings.
3. LED indicators 4-6 should be illuminated (either DIM or ON); all others (indicators 1-3, 7 and 8) should
be off.
4. Press the CFG button repeatedly to step through the available 4
th
-pair settings as shown below.
5. To leave configuration-mode step through all the options OR leave the buttons untouched for 10
seconds.

The 4
th
-pair operating mode is defined by presence of
option-module. This setting cannot be changed because
an option-module is installed (232, SA or SAP).
Note: If an option module is not installed, this setting will
effectively “mute” the 4
th
-pair signals. This can be useful
sometimes for diagnostic purposes.
