The 2500P-ECC1 Ethernet Communications Coprocessor module extends the communications

capabilities of CTI 2500 Series® controllers, offering increased connectivity and additional

protocols. By offloading the processing of communications protocols from the 2500 Series®

controller, the 2500P-ECC1 module minimizes the impact of network communications on

controller performance.

The 2500P-ECC1 module communicates with the 2500 Series® controller via a high speed

Ethernet link. Data is transferred between the controller and module using a high density

Ethernet messaging protocol, which is capable of transferring a large amount of data while

minimizing the impact on the 2500 Series® controller.  The controller processes data transfer

requests from the 2500P-ECC1 in a configurable time slice, allowing the user to limit the amount

of scan time used to service the requests.  Up to four 2500P-ECC1 modules can communicate

concurrently with a 2500 Series® controller.
