tion and system control, but they communicate with other
E2s to provide logging, alarm control, and other functions.
In addition to these, Retail Solutions also offers Echeloncompatible
input and output boards similar to those available
for the RS485 Network.

Figure 1-3 shows the E2 RX peripherals that communicate
across the Echelon Network:
• CC-100 - Case control board - controls all lights,
fans, defrost, and refrigeration for a single case. The
CC-100 controls pulse or stepper valves to provide
precise evaporator control, resulting in better temperature
maintenance and energy efficiency.
• ESR8 - Evaporator stepper regulator - the analog
outputs on this board allow the E2 to control circuit
temperature in up to eight circuits using suctionside
mounted electronic evaporator pressure regulators
(EEPRs).
• TD3 - Temperature display - has three inputs that
monitor case temperature, product temperature and
defrost status.
• Third Party Echelon Devices - Echelon® LON-
MARK® devices communicate with E2 through its
"Open Echelon" networking feature, and require a
license key and a description file that is loaded into
the E2 that enables communication.
1.4.3 Interconnection With Other
E2s
In large installations where more than one refrigeration
system is present, or where E2s are controlling both refrigeration
and building HVAC systems in the same site, the
E2s share information with each other across either the
Echelon Network or via Ethernet.
