QM-MD7x2
NOTE:
If an input greater than “7” or “07” is sent, the command is ignored. If an
output destination less than “1” / “01”, or greater than “2” / “02”is sent to the
MD7x2, the command is ignored.
When the verbose mode is on and the routing status changes while the MD7x2 is in
the system mode, or if the MD7x2 is polled for the status of an output, the MD7x2
replies with one of the responses listed in the following table.
Switching/Routing Status Replies
MESSAGE DEFINITION
IxOyA
\r
New audio route if audio route has changed
where x will be a two-digit number from 00 to
07 and y will be a two-digit number from 01 to
02.
IxOyV
\r
New video route if video route has changed
where x will be a two-digit number from 00 to
07 and y will be a two-digit number from 01 to
02.
SA1V1M1A2V2M2\r Current
switching schema of all of the outputs
where a1 is the input routed to output 1 audio,
v1 is the input routed to output 1 video, m1 is
the microphone input routed to output 1
microphone, a2 is the input routed to output 2
audio, v2 is the input routed to output 2 video,
and m2 is the microphone input routed to
output 2 microphone. Each number will be two
digits.
If a switch command is sent and an output is already at the new setting, serial
feedback will not be provided for that output.
NOTE:
There is no serial feedback for any switches made while the MD7x2 is in
the local mode, even if the verbose mode is on. Use the
LocalMode-FB
digital
signal to signal when the device leaves local mode in order to trigger the “S?\r”
command to query the MD7x2 for the current status of all outputs.
“Switch All” Example
The string “C020400050102\r” sends the following command:
•
Switch Audio Input 2, Video Input 4 and no microphone signal to QM Out
1.
•
Switch Audio Input 5, Video Input 1, and the microphone signals from
QM7 to QM Out 2.
If polled for the status of all outputs (S?\r), the device response on
Control-FB$
will
be: “S020400050102\r”.
