E2 Enhanced RX and BX Controllers and
RMCC/BEC/BCU Retrofitting
Technical Bulletin
Overview
This technical bulletin describes E2E retrofitting of supermarkets with existing REFLECS controllers.
STEP 1: Preparing for Retrofit
When replacing a REFLECS unit with an E2E, there are several major differences that must be taken into
account.
1. All REFLECS units are powered by 110/220VAC line voltage. E2E controllers are powered by 24VAC
non center-tapped transformers. Refer to the E2E User's Manual (P/N 026-1614 Rev 5 or later) for more
information on powering the E2E controller.
2. REFLECS units use an RS485 (COM B) network to connect to a 485 Alarm Panel. E2E does not support
the 485 Alarm Panel.
3. REFLECS units use an RS232 (COM C) host network to connect all units to a modem for alarm dial-out.
E2Es may use either Echelon or Ethernet for box-to-box communication. The existing host network
wiring may not be used for E2E box-to-box communication - you will either have to rewire using
approved Echelon network wire, or wire CAT 5 cable to an approved network router or switch. Refer
to the E2E User's Guide for more information on box-to-box wiring.
4. COM A and COM D networks (the RS485 I/O networks) use the same wire and polarity for both the
REFLECS and E2E controllers. No rewiring of the I/O network will be necessary; just unplug the COM A
and/or COM D connectors, and plug them into the I/O port(s) on the E2E PIB (see "Transferring the
COM A and COM D Networks" below).
STEP 2: Transferring the COM A and COM D Networks
The COM A and COM D I/O networks on the RMCC/BEC/BCU are where connections to all I/O devices, such
as 16AIs and 8ROs are made. The two networks are interchangeable, each one capable of connecting up to
31 devices.
