QuickMedia Distribution System Crestron QM-MD8x8

When the verbose mode is on and the routing status changes while the MD8x8 is in

the system mode, or if the MD8x8 is polled for the status of an output, the MD8x8

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

08 and y will be a two-digit number from 01 to

08.

IxOyV\r

New video route if video route has changed

where x will be a two-digit number from 00 to

08 and y will be a two-digit number from 01 to

08.

SA1V1A2V2A3V3A4V4A5V5A6

V6A7V7A8V8\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, a2 is

the input routed to output 2 audio, and so on.

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 MD8x8 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 MD8x8 for the current status of all outputs.

“Switch All” Example

The string “C0204xx0107070302050504060808xx03\r” sends the following

command:

• Switch Audio Input 2 and Video Input 4 to QM Out 1.

• Retain the current Audio Input on QM Out 2 and switch Video Input 1 to

QM Out 2 (current Audio Input is 2).

• Switch Audio Input 7 and Video Input 7 to QM Out 3.

• Switch Audio Input 3 and Video Input 2 to QM Out 4.

• Switch Audio Input 5 and Video Input 5 to QM Out 5.

• Switch Audio Input 4 and Video Input 6 to QM Out 6.

• Switch Audio Input 8 and Video Input 8 to QM Out 7.

• Retain the current Audio Input on QM Out 8 and switch Video Input 3 to

QM Out 8 (current Audio Input is 2).

If polled for the status of all outputs (S?\r), the device response on Control-FB$ will

be: “S02040201070703020505040608080203\r”.
