The MD4x2 contains two 2-position terminal block connectors that provide 24VDC 
power to the Cresnet ports on each of the QM ports. Power to the QM power ports 
can be supplied by the Crestron C2N-SPWS300 External 300 Watt Power Supply or 
the Crestron CN-PWS75 External 75 Watt Power Supply. For more information, 
refer to “Hardware Hookup” on page 16.

This 4-position terminal block connector is used to connect the MD4x2 to the 
Cresnet system. Data and power for the MD4x2 are provided via the connection. 
Refer to “Network Wiring” on page 9. 

Indicators & Pushbuttons 

The MD4x2s indicators and pushbuttons are described in the following paragraphs.  

PWR (Power) 

 

This LED, located on the front panel, illuminates when 24 VDC is supplied to the 
MD4x2 via the NET port. 

NET 

 

This LED, located on the front panel, illuminates when communication between the 
control system and the MD4x2 is established (the unit is polled on the network). 
Illumination indicates that the SIMPL Windows program currently loaded has a 
network device defined at the same Net ID as the MD4x2. The LED flashes when 
communication with the processor occurs. 

AUDIO BREAK 

 

When operating in the local mode, press this button to enable separate switching of a 
QM signal’s audio and video portions. Push again to disable this feature and enable 
simultaneous switching. When the accompanying LED is illuminated, a QM signal’s 
audio and video portions can be switched separately. When the LED is not 
illuminated, the QM signals audio and video portions are switched simultaneously. 

For more information on the MD4x2’s operating modes, refer to “Operating Modes” 
on page 28. 

 

Press this button to switch the audio portion of QM signals when operating in the 
local mode. When the accompanying LED is illuminated, only the audio portion of a 
QM signal will be switched. Audio can be switched separately from video only when 
the 

AUDIO BREAK

 LED is illuminated. 

While in the system mode, pressing 

will indicate where the audio portion of a 

signal is routed. For more information on the MD4x2’s operating modes, refer to 
“Operating Modes” on page 28. 

 

Press this button to switch the video portion of a QM signal when in the local mode. 
When the accompanying LED is illuminated, only the video portion of a QM signal 
will be switched. Video can be switched separately from audio only when the 

AUDIO BREAK

 LED is illuminated.
