Network Poll Accelerator Crestron C2N-NPA8

Ports/Connectors

The ports/connectors on the top panel of the C2N-NPA8 are described in the

following paragraphs.

NOTE: Interface connectors for the PWR and NET ports are provided with the

C2N-NPA8.

NET A - H

These eight segments provide 32 standard (24 Y Z G) Cresnet connectors (in groups

of four) for Cresnet device connections. Each group of four supports 32 electrical

Cresnet connections.

NOTE: Although there are eight segments with four connectors each, a control

system can only address 252 devices (03 through FE).

POWER

These connectors (quantity eight) are used to supply 24VDC power to each segment

as well as providing a jumping point for powering another segment on the

C2N-NPA8. To power the C2N-NPA8, 24VDC power must be supplied to a Cresnet

connector or the power connector on NET A or NET B. For more details, refer to

“Power Connections” on page 12.

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do

so could cause equipment damage or void the Crestron warranty.

LAN

An 8-position RJ45 port is used for an Ethernet connection to a control system with

Ethernet capabilities. Refer to the following table for the Ethernet connector signals

and use an appropriate cable (not supplied). For information on connecting the LAN

port to a control system, refer to “Configuring for TCP/IP Communications” on

page 15.

NOTE: Only one C2N-NPA8 can be connected to a control system.
