Control Subnet Application
16 • 3-Series Control Systems: CP3 & CP3N
NOTE: The CP3 can be powered by the 4-position terminal block connector labeled
NET or with the (included) 24 Vdc power pack.
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.
The Control Subnet can host up to 64000 Crestron Ethernet devices. Connect a
Crestron Ethernet switch such as the CEN-SWPOE-16 16-Port Managed PoE Switch
(sold separately) to the CP3N's CONTROL SUBNET port to use as a connection
point a variety of Crestron Ethernet devices.
NOTE: If the CP3N is operating in the Isolation mode, Crestron Ethernet devices
that require Internet access should not be connected to the CONTROL SUBNET
port (either directly or indirectly). Any Crestron Ethernet device that requires an
Internet connection should be connected to the local area network. For details, refer
to "Control Subnet (CP3N Only)" on page 19.
