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 jumper in external power. Additional power is rarely
required; 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
