7.4.1 INDEPENDENT CHANNEL SWITCHING
To enable the MX2222AT to switch all six
channels independently, use the following
procedure:
Reset Unit
1. Unplug or turn OFF the power to the unit.
2. Press and hold the STAND BY button while
plugging the unit back in (power on).
Set Independent Switching
1. Unplug or turn OFF the power to the unit.
2. Press and hold Input 2 in the AUDIO section
on the front panel while plugging the unit

When the MX2222AT is in this mode, each of
the channels is assigned to a group as follows:
Group 1 Red
Group 2 Green
Group 3 Blue
Group 4 Horizontal Sync
Group 5 Vertical Sync
Group 6 Video
Only the first three groups may be controlled
through the front panel. The RGBHV buttons
control red, the VIDEO buttons control green,
and the AUDIO buttons control blue.
Through RS-232, control of each of the six
groups is available.
When the MX2222AT is in independent channel
switching mode, the audio-follow features will
be as follows:
”RGBHV +Audio” OFF. ”Video +Audio” OFF
In this mode, the six channels of the
MX2222AT are fully independent and can be
controlled using RS-232 commands. The front
panel can also control three of the six channels.
”RGBHV +Audio” ON. ”Video +Audio” OFF
In this mode, audio follows the RGBHV auto-
switch input selection. The audio channel can
be selected independently, but it will
synchronize with RGBHV when selected. The
video channel is independent.
”RGBHV +Audio” OFF, ”Video +Audio” ON
In this mode, audio follows the video auto
switch input selection. The audio channel can
be selected independently. The RGBHV
channel is still completely independent.
”RGBHV +Audio” ON. ”Video +Audio” ON
In this mode, video and audio follow the
RGBHV channel selection. Audio follows the
video channel selection. In other words,
RGBHV is master to video and audio. Video is
master to audio only. Audio can still be
completely independent until video or RGBHV
is used to select another channel.
