Configuration Mode-1, 4
th
Pair Options:
The MVII-AK1200 provides several options for using the 4
th
-pair signals (pairs 1-3 are
generally used for video). The factory-default settings support analog audio (L+R summed) on the 4
th
-pair. Note that the connected
MultiView transmitter and any daisy-chained receivers must be configured with a matching 4
th
-pair operating mode. Otherwise, the
desired 4
th
-pair signal will not work as expected
– but the video will not be affected.
(starting in normal-mode)
Press and hold the
CFG
button until the
CFG
indictor is
ON
. Release the
CFG
button.
o
LEDs 1-8 will show the current value for all Mode-1 configuration settings as bright/off.
Press and release the
SKEW/SEL
button twice.
LED indicators 4-6
should be illuminated (either DIM or ON); all others (indicators 1-3, 7 and 8) should be off.
Press the
UP
and
DOWN
buttons to step through the available 4
th
-pair settings as shown below.
To leave configuration-mode, leave the buttons untouched for 10 seconds or press the
CFG
button.

th
-pair operating mode is defined by the presence
of the option-module (232/SA/SAP) and this setting cannot be changed.
If the option-module is not installed:
4
th
-pair signals are disabled. This effectively
“mutes” anything being sent on the 4
th
pair. This can be useful for diagnostic
purposes.

Configuration Mode-1, Vsync Polarity:
The MVII-AK1200 provides settings for Vsync polarity: (+) or (-).
(starting in normal mode)
Press and hold the
CFG
button until the
CFG
indictor is
ON
. Release the
CFG
button.
o
LEDs 1-8 will show the current value for all Mode-1 configuration settings as bright/off.
Press and release the
SKEW/SEL
button three times.
LED indicator 7
should be illuminated (either DIM or ON); all others (indicators 1-6 and 8) should be off.
Press the
UP
and
DOWN
buttons to change Vsync polarity from Positive (
bright
) to Negative (
dim
).
To leave configuration-mode, leave the buttons untouched for 10 seconds or press the
CFG
button.
Note:
This setting only has an effect if the sync-
mode is set to “Fixed”.
Configuration Mode-1, Hsync Polarity:
The MVII-AK1200 provides settings for Hsync polarity: (+) or (-).
(starting in normal mode)
Press and hold the
CFG
button until the
CFG
indictor is
ON
. Release the
CFG
button.
o
LEDs 1-8 will show the current value for all Mode-1 configuration settings as bright/off.
Press and release the
SKEW/SEL
button four times.
LED indicator 8
should be illuminated (either DIM or ON); all others (indicators 1-7) should be off.
Press the
UP
and
DOWN
buttons to change Hsync polarity from Positive (
bright
) to Negative (
dim
).
To leave configuration-mode, leave the buttons untouched for 10 seconds or press the

button.
Note:
This setting only has an effect if the sync-
mode is set to “Fixed”.
