MultiView™ II DVI-Tx Installation and User Guide 15

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 the optional SAP daughterboard is installed, 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.
