Crestron C2N-VEQ4 Cresnet 4-Channel Digital Volume Control
Operations Guide - DOC. 6135A Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 • 7
Industry Compliance
As of the date of manufacture, the C2N-VEQ4 has been tested and found to comply
with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling.
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Setup
Network Wiring
CAUTION: In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire, and only Crestron Certified Wire,
should be used. Failure to do so may incur additional charges if support is required to
identify performance deficiencies as a result of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system
(http://www.crestron.com/calculators
).
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Crestron website.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the Cresnet power usage of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the Cresnet power
usage of each unit to be daisy-chained must be added together to determine the
Cresnet power usage of the entire chain. If the unit is a home-run from a Crestron
system power supply network port, the Cresnet power usage of that unit is the Cresnet
power usage of the entire run. The length of the run in feet and the Cresnet power
usage 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 the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
R <
L x P
