DESCRIPTION
The EC485 converter is an accessory for both the Fireye®FLAME-MONITOR™ flame safeguard
control system and the 45FS1 and 45UVFS1 Flame Signature Scanner™ controls. The EC485 is an
RS232 to RS485 converter used to perform the following functions:
1. Customize the operating control messages and lockout alarm messages of the E300 Expansion
Module.
2. Interface between an IBM compatible PC running the FS700 Communication Software and the
45FS1 and 45UVFS1 Flame Signature Scanner to provide remote communications capability.
3. Interface between an IBM compatible PC running the E720 Communication Software and the
E340 Burner Management Control System to provide remote communications capability.
The EC485 provides the means to directly connect to any device that has RS485 communication
capability.
The EC485 is packaged with an RJ12 telephone jack mounted on a PC board to provide an easy
method to use the ED512 cables to interface to the EP programmers when customizing E300 mes-
sages.
The EC485 also includes a 120 VAC to 12 VDC power supply.
RS-485 Driver Control, RTS / SD Jumper:
The RS-485 side of the converter must be enabled to transmit data, and disabled when not transmit-
ting. Via a jumper on the converter, either “RTS” or “SD” is selected as the control means to auto-
matically enable and disable the converter.
With SD (Send Data) control selected, circuitry within the converter automatically controls the
transmitter by sensing the data on the RS-232 side. This circuitry enables the driver during data
transmission and disables the driver after the last character has been sent.
With RTS (Request To Send) control selected, the external software controls the driver by raising
and lowering the Request To Send line on the RS-232 side. Because the RTS timing is not precisely
controlled, this method is not usually suitable for Windows based systems.

CUSTOMIZING E300 MESSAGES
The user can customize the lockout alarm message associated with each pair of terminals of the E300
Expansion Module. Each customized message can be up to 40 characters in length.
Note: Messages longer than 16 characters in length will scroll across the ED510 display. Messages
longer than 8 characters will scroll across the ED500 display.
The following equipment is required:
•An IBM compatible PC with E300 programming software (available on the E700 or E720 soft-
ware programs).
•EC485 (RS232 to RS485 converter with power supply).
•An ED512-2, -4, or -8 cable.
•EP programmer with an Engineering code of 28 or later.
1. Connect the EC485 converter to the serial COMMunication port of the IBM PC using an
appropriate serial communications cable. Depending on whether the IBM PC has a 9-pin or a
25-pin serial communications port, the cable should be configured as follows:
CABLE CONNECTIONS, DB25 to DB25 CABLE CONNECTIONS, DB25 to DB9
2. Connect the ED612 (RJ12 female connector provided with the EC485) to terminals TD(A), TD
(B), RD(A), and RD(B) on the EC485. The pins on the ED610 will line up with the terminals on
the EC485 converter.
3. Set the jumpers on the EC485 converter to SD and ECHO OFF. See diagram below.
4. Plug on end of the ED512-2, -4, -8 cable into the RJ12 jack on the ED612, and the other end into
either of the RJ12 jacks on the EP programmer.
5. Hook up power supply 61-6689 to +12V and GND. White stripe wire is (+) lead.
The Flame-Monitor control must be powered, and the operating control (L1-13) should be open.
For complete details on customizing the E300 lockout messages, refer to Bulletin E-3001.

COMMUNICATING WITH 45FS1/45UVFS1 SIGNATURE SCANNERS OR 95IRS2/95UVS2/95DSS2
INTEGRATED SCANNERS
These flame scanners provide remote communications capability over an RS485 communication
data link. The data link uses a single, twisted shielded pair wire (e.g. Belden 8761) in a multi-drop
(e.g. daisy chain) wiring configuration. A Fireye communication software program running on an
IBM compatible PC is required for communicating with the flame scanners.
Since the flame scanners communicate over the data link via RS485, the EC485 RS232/RS485 con-
verter is required for the RS232 Serial Comm Port of the IBM PC. The EC485 converter should be
wired in the following manner:
For complete details on wiring and communicating with these flame scanners, refer to the following
bulletins:
COMMUNICATING WITH THE E340 BOILER CONTROL
The E340 Boiler Control also communicates over an RS485 communication data link. The data link
uses a single, twisted shielded pair wire (Belden 8761) with the E340 controls wired in a multi-drop
(e.g. daily-chain) wiring configuration. The Fireye communication software program (P/N E720W)
is required for communication with the E340 controls.
Fireye recommends using the E500 Communication interface when communicating with the E340
controls, since the E500 provides communication with the Flame-Monitor™ flame safeguard con-
trols as well. However, the EC485 converter can be used to communicate only with the E340 con-
trols.
