1.4Networking Overview

1.4.1E2 I/O Network

Most of the general purpose input and output commu- nications devices required by the E2 to control refrigera- tion systems are connected to the E2 via the I/O Network. The I/O Network is a simple RS485 three-wire connection that allows data interchange between input boards (which read sensor values and digital closures), output boards (which carry out commands from E2’s control applica- tions), and the E2 itself.

The I/O Network is the same thing as the COM A and COM D Networks found on Retail Solutions’ previous generation of controllers, REFLECS. This allows current owners of Retail Solutions’ Refrigeration Monitor and Control (RMC) or Refrigeration Monitor and Case Control (RMCC) controllers to easily retrofit with an E2 RX with- out need for re-wiring.
