7 E2 Ethernet Peer Communications

Communication between E2 controller version 2.10 or greater may now be implemented through an Ethernet net- work using TCP/IP protocol. To utilize peer connections over Ethernet, the following tasks must be performed:

•Upgrade the E2 controller firmware to version 2.10 or greater.

•Install an industry-standard Ethernet switch(es) or hub(s) in an area or areas nearby the E2 controllers.

•Install Ethernet straight-through cabling at the site from each E2 to the switch or hub. Installation of RJ-45 connectors may be necessary to achieve this goal. The recommended cabling is CAT 5.

Configurations

If using an open network configuration (see Section 7.4.2, Open Network Layout), contact your IT Network Administrator for all IP configuration information (IP Address, Subnet Mask, Primary and Default Gateway set- tings).

7.2Hardware

Specifications

Standard industry-accepted practices for wiring of Ethernet networks are expected. E2 controllers use a star topology, identical to PC deployment. This includes a unique “point-to-point” run from a switch or hub to the controller (see Table 7-1for hub part numbers for order- ing). This is done with Category5 (or better) cable. Maxi- mum distance for a run of 10BaseT is 328 feet (100 meters) (11.5 dB loss max).

•The maximum number of controllers allowed on an IP subnet is 20. All E2 controllers that must com- municate with each other must be on the same sub- net.

•Recommended Ethernet cabling is CAT 5 (straight- through cable).

•328 feet (100 meters) is the maximum distance allowed between devices before a switch or hub must be added.
