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).
