Crestron QM-RMCRX  

         QuickMedia™ Receiver/Processor

 

QM-RMCRX chassis must also be connected to an earth ground (building steel).

The QM-RMCRX can be powered through the NET network connector, or by 
the external PW-2420 power pack (60W) included but not by both methods. 
Use the provided external power pack to provide power to peripheral Cresnet 
devices (via the Cresnet connector).  

If additional power is needed, Crestron recommends its CNPWS-75 (75 watts) 
external power supply. 

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure 
to do so could cause equipment damage or void the warranty. 

NOTE:  Use care in wiring installations to avoid applying 24 VDC power to 
Cresnet wiring from an external power pack as well as from a system device that 
contains its own power supply. Although this condition should not cause any 
damage, Crestron does not recommend it.  

NOTE: In larger system configurations that require more power than supplied 
by Cresnet, disconnect the +24 VDC wire from the QM-RMCRX Cresnet 
connector and provide the +24 VDC power to the peripheral devices by an 
alternate Crestron power source. 

Before uploading a program to the QM-RMCRX or performing diagnostic 
functions, you must connect the QM-RMCRX system to the PC. The connection 
can be either serial or TCP/IP. 

NOTE:  For laptops and other PCs without a built-in RS-232 port, Crestron 
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a 
USB-to-serial adapter must be used, Crestron has tested the following devices 
with good results: 
 
 

Belkin (large model) F5U103 

 I/O 

Gear 

GUC232A 

 

Keyspan USA-19QW (discontinued) 

 
Results may vary on the computer being used. Other models, even from the 
same manufacturer, may not yield the same results.
