Check Network Wiring

Use the Right Wire

In order to ensure optimum performance over the full range of your installation

topology, Crestron Certified Wire and only Crestron Certified Wire may be used.

Failure to do so may incur additional charges if support is required to identify

performance deficiencies because of using improper wire.

Calculate Power

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. The EIG connector on the DM

switcher is used to bring in external power. Additional power is rarely required as

switchers provide enough power for their maximum configuration of room

controllers and repeaters. Please use the DMNet Power Calculator to help calculate

how much power is needed for the system (www.crestron.com/calculators

Refer to the following table for commonly used resolutions and maximum DM-CBL

cable lengths.

is the A conductor and the B conductor.
