Crestron QM-MD4x2 QuickMedia Distribution System
NOTE: The setting for the verbose mode is retained even after power to the MD4x2
is cycled.
NOTE: Commands can be sent to the MD4x2 regardless of the status of the verbose
mode.
Verbose Mode Commands
COMMAND FUNCTION
R0\r Verbose mode off
R1\r Verbose mode on
R?\r Get verbose mode status
When the state of the verbose mode changes to on, or if polled for status, the MD4x2
replies with one of the responses listed in the following table.
Verbose Mode Status Replies
MESSAGE DEFINITION
R1\r Verbose mode on
R0\r Verbose mode off
Switching/Routing Functions
Switching/Routing Commands
COMMAND* FUNCTION*
IxOyA\r Switch input x to output y audio only*
IxOyV\r Switch input x to output y video only*
IxOy\r Switch input x to output y audio and video*
CA1V1XXV2\r Switches all outputs. Where A1 is the audio
input routed to QM OUT 1, V1 is the video
input routed to QM OUT 1, A2 is the audio
input routed to QM OUT 2, and V2 is the video
input routed to QM OUT 2. Each value is 2
digits, and thus can range from 00 (for no
source) to 04, corresponding to QM inputs 1
through 4. The "XX" (or "xx") specifier should
be used to denote a "don't care" condition, in
which case the respective output should retain
its state.
OyA?\r Get status of output yA
OyV?\r Get status of output yV
S?\r Get status of all outputs
* Where “x” should equal 0 (for no source) through 4, corresponding to QM
inputs 1 through 4; and “y” should equal 1 through 2, corresponding to QM
outputs 1 through 2. Thus to route a digital audio source from QM IN 4 to QM
OUT 2, set the Control$ input to “I4O2A\r”. Alternatively, the command
string can consist of 2-digit values, e.g.,“I04O02A\r”.
NOTE: If an input greater than “4” or “04” is sent, the command is ignored.
NOTE: If an output destination less than “1” / “01”, or greater than “2” / “02”is sent
to the MD4x2, the command is ignored.
