QuickMedia™ Receiver/Processor
Ground Wire Connections
Proper grounding is required. Connect the ground from the QM peripheral (in
this example a QM-WMC) to earth ground. Connect the Cresnet shield lead at
the QM-RMCRX-BA control processor to the ground lead. The control
processor chassis must also be connected to an earth ground (building steel).
Refer to the following grounding diagram.

Power Supply
The QM-RMCRX-BA can be powered through the NET network connector
(Cresnet), or by the external PW-2420 power pack (50W) 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-BA Cresnet
connector and provide the +24 VDC power to the peripheral devices by an
alternate Crestron power source.
Crestron Toolbox
The Crestron Toolbox (replacement for Crestron Viewport, you may continue to
use Viewport if desired) is a broad-based software package that accomplishes
multiple system tasks, primarily using an RS-232 or TCP/IP connection between
a PC and one or more Crestron control systems.
You can use the Crestron Toolbox to:
•
Observe system processes.
•
Upload operating systems and firmware.
•
Upload programs and touchpanel projects.
•
Set or change device Network IDs.
