Changing Internal Settings: In configuration-mode (CFG indicator = on), the CFG and SEL buttons, plus the LED indicators (1-8)
will allow you to change internal configuration settings. The changes are effective immediately and are saved in non-volatile memory.
 To enter configuration-mode: Press CFG button once. The CFG indicator will turn on, confirming you are in configuration-
mode. Once in this mode, the LED indicators 1-8 will display the current settings as described in the tables below.
 To exit configuration-mode: Leave the buttons untouched for 10 seconds. The CFG indicator will turn off (normal-mode).
Sync-mode Options: The DVI-TX is factory-configured for auto-detecting the proper sync-mode (RepliSync-I normal/stretched). This
mode is generally compatible with all existing MultiView receiver products that support RepliSync (if they are also using their default
settings). However, some video sources may require a custom sync-mode setting (most especially at 1080p and 1920x1200 video
resolutions). For these cases, one of the other sync-modes can be selected. Note that any connected MultiView receiver MAY also
require a change to its sync-mode settings. Otherwise, you may not get a proper video display output at that receiver.
 (starting in normal-mode) Press and release the CFG button once to access configuration-mode. CFG indicator = on.
 Press and release the SEL button once. You will now be able to change sync-mode settings.
 LED indicators 1-3 should be illuminated (either DIM or ON); all others (indicators 4-8) should be off.
 Press the CFG button repeatedly to step through the available sync-mode settings as shown below.
 To leave configuration-mode step through all the options OR leave the buttons untouched for 10 seconds.

The DVI-TX will auto-detect the required RepliSync-I mode (“normal” or
“stretched”). This is the factory default setting.
dim dim ON
Force RepliSync-I normal Horizontal sync. pulse encoding.
dim ON dim Force RepliSync-I “stretched” Horizontal sync. pulse encoding.
dim ON ON
Force RepliSync-II.
ON dim dim
Force fixed-sync mode. NOTE: A connected MultiView receiver must also be in
fixed-sync mode and with H/V polarities selected at the receiver.

Pair Options: The DVI-TX provides several options for using the 4
th
-pair signals (pairs 1-3 are generally used for video). The
factory-default setting support analog audio (L+R summed) on the 4
th
-pair. 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.
Note: 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.
 (starting in normal-mode) 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

-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.

To reset all user-configurable options back to factory-default settings:
 Disconnect the DC power cable (or AC power).
 Press and hold the CFG button.
 Connect the DC power cable (or AC power). All LEDs blink 3 times – all settings are now changed back to factory-defaults.
 Release the CFG button.
