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.

The E2E’s standard I/O port (COM2, located on the E2E Power Interface Board, or PIB) also has two

connectors (Figure 1). Unplug the connectors from the COM A and COM D plugs, and plug them into the

COM2 plugs on the E2E.

STEP 3: E2E Termination Jumper Settings

The network termination jumpers, directly above the two COM2 plugs on the PIB, will need to be set to the

same positions as the COM A and COM D termination jumpers on the RMCC/BEC/BCU. The rules for

termination on E2E I/O networks are the same as the rules for RMCC/BEC/BCU I/O networks. Set the three

jumpers to the middle I/O (terminated) position if the port is at the end of a network segment or the hub of

a star configuration, and down NO (unterminated) if the port is in the middle of a segment.

There is one set of RS485 jumpers for each RS485 port (COM2A-2B; COM6; and COM4A-B). Jumpers J8-J10

are located directly above the COM2A connector port, and jumpers J11-J13 are located directly above the

COM2B port. The RS485 termination jumpers (J8-J22) are used to terminate the devices at the beginning

and end of an RS485 Network. If the E2 is the beginning of all RS485 I/O or MODBUS Networks, all three of

these jumpers should be set to the up position. For MODBUS, the jumpers should all be in the top-most

position (MOD). For I/O Net, the jumpers should be in the middle position (I/O). For no termination, set the

jumpers to the down position (NO).

Refer to the E2E User’s Manual (P/N 026-1614 Rev 5 or later) for expanded communication setup

information.

STEP 4: E2E Baud Rate Settings

Because the COM A and COM D networks of an RMCC/BEC/BCU must communicate at the same baud rate,

all I/O boards connected to the RMCC/BEC/BCU were also set to communicate at 19200 baud. Because the

default E2E baud rate for I/O networks is 9600 baud, you will need to change the COM2 baud rate setting.

This must be done in the C3: Serial tab of the E2E’s General Controller Info screens.

1. Log into the E2 with Level 4 password access.

2. Press  to access the General Controller Info screen.

3. Press +(or two times) to access the C3: Serial tab (Figure 2).

You will need to set two parameters in the C3: Serial tab.

1. In the COM2 Connection field, if the value displayed is something other than IO Net, set this parame-

ter to IO Net.

2. In the COM2 Baud field, set the value to 19.2 Kbaud.
