Check Network Wiring

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.
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).
CresFiber fiber optic cables provide for longer distances between the DigitalMedia
switcher and a DigitalMedia Room Controller. For more information, refer to the
latest version of the Crestron DigitalMedia Design Guide (Doc. 4789).
Refer to the following tables for maximum cable lengths using various cables.

twisted pair is the +24V conductor and the GND conductor and the other twisted pair
is the A conductor and the B conductor.
