NOTE: Ensure the unit is properly grounded by connecting the chassis ground lug
to an earth ground (building steel).
NOTE: To prevent overheating, do not operate this product in an area that exceeds
the environmental temperature range listed in the table of specifications.
NOTE: The CP3 can be powered by the 4-position terminal block connector labeled
NET or with the (included) 24 Vdc power pack.
Control Subnet (CP3N Only)
The CP3N has a dedicated Control Subnet that is used for communication between
the control system and Crestron Ethernet devices. This subnet allows for dedicated
communication between the control system and Crestron Ethernet devices without
interferences from other network traffic on the LAN.
CAUTION: Do not connect the CONTROL SUBNET port to the LAN. The
CONTROL SUBNET port must only be connected to Crestron Ethernet devices.
