1.4 Networking Overview
1.4.1 E2 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.
Figure 1-2 shows the peripherals that make up the I/O
Network:
