th
Pair Settings
The DVI-TX provides several options for using the 4
th
-pair signals (pairs 1-3 are generally used for video). Note
that any connected MultiView™ 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):
 Press and release the CFG button once to access configuration-mode (CFG indicator = on).
 Press and release the SEL button twice. You will now be able to change 4
th
-pair option settings.
 LED indicators 4-6 should be illuminated (either DIM or ON); all others (indicators 1-3, 7 and 8) should
be off.
 Press the CFG button repeatedly to step through the available 4
th
-pair settings as shown below.
 To leave configuration-mode step through all the options OR leave the buttons untouched for 10
seconds.

-PAIR OPERATING MODE
dim dim dim
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.
dim dim ON
Direct pass-through of 4
th
-pair wires (custom
applications).
dim ON dim
External analog (L+R summed) audio.
This is the factory-default
mode for an (A) model
transmitter.
dim ON ON
External S/PDIF digital audio. Input-impedance = 75-
ohms.
ON dim dim
Simplex-serial.
This is the factory-default
mode for an (S) model
transmitter.
