Power Supply
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.
Establishing Communication with the
QM-RMCRX
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.
