Crestron qm-rmcrx Manuel D’Utilisation
QuickMedia™ Receiver/Processor Crestron QM-RMCRX
DRAM is used by the operating system for dynamic storage of variables, signals
and other constructs used at runtime. The actual amount of DRAM used at any
given time depends on the particular program that is running, i.e., usage is
variable, or dynamic, during normal operation.

Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the
wiring diagram(s) appropriate for your specific system configuration, available
from the Downloads | Product Manuals | Wiring Diagrams section of the

When calculating the wire gauge for a particular Cresnet run, the length of the
run and the power factor of each network unit to be connected must be taken
into consideration. If Cresnet units are to be daisy-chained on the run, the power
factor of each unit to be daisy-chained must be added together to determine the
power factor of the entire chain. If the unit is a home-run from a Crestron system
power supply network port, the power factor of that unit is the power factor of
the entire run. The length of the run in feet and the power factor of the run
should be used in the following resistance equation to calculate the value on the
right side of the equation.

Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
PF = Power factor of entire run (or chain).
R < L x PF

Where:
The required wire gauge should be chosen such that the resistance value is less
than the value calculated in the resistance equation. Refer to the following table.
