Crestron electronic C2N-VEQ4 Setup

Operations Guide - DOC. 6135A Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 • 7

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

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).
