Crestron QM-MD4x2 QuickMedia Distribution System
QM-MD4x2 Analog Input Signal Descriptions
INPUT DESCRIPTION
VideoOut1 and VideoOut2 Select the QM video source to be switched to the
indicated QM output. Valid analog values range
from 0 (for no source) through 4, and correspond
to the QM 1 and QM4 inputs. Thus to route a
video source from QM In 4 to QM Out 2, initialize
VideoOut2 to 4d.
AudioOut1 and AudioOut2 Select the QM audio source to be switched to the
indicated QM output. Valid analog values range
from 0 (for no source) through 4, and correspond
to the QM 1 and QM4 inputs. Thus to route a
audio source from QM In 4 to QM Out 2, initialize
AudioOut2 to 4d.
NOTE: When programming the MD 4x2 using digital and analog commands, serial
commands should not be used. Similarly, if the MD 4x2 is to be programmed with
serial commands, digital and analog commands should not be used. However, analog
outputs can be monitored.
Signal Values for VideoOut Selections
SIGNAL VALUE SOURCE
0 Mutes the video output
1 Selects video input 1
2 Selects video input 2
3 Selects video input 3
4 Selects video input 4
Signal Values for AudioOut Selections
SIGNAL VALUE SOURCE
0 Mutes the audio output
1 Selects audio input 1
2 Selects audio input 2
3 Selects audio input 3
4 Selects audio input 4
NOTE: Use an Analog Initialize to send a decimal input signal to the symbol.
QM-MD4x2 Serial Input Signal Descriptions
INPUT DESCRIPTION
Control$ Accepts serial commands for routing signals.
Allows users to query the switch for current
status. Refer to “Appendix: Serial Protocol” on
page 32.
NOTE: When programming the MD 4x2 using serial protocol, digital and analog
commands should not be used. However, digital and analog output can be monitored
by the control system. Similarly, if the MD
4x2 is to be programmed with digital and
analog commands, serial commands should not be used.
