EC485
RS232/RS485
CONVERTER
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.
2.
3.
Customize the operating control messages and lockout alarm messages of the E300 Expansion
Module.
Interface between an IBM compatible PC running the FS700 Communication Software and the
45FS1 and 45UVFS1 Flame Signature Scanner to provide remote communications capability.
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 messages.
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 transmitting. Via a jumper on the converter, either “RTS” or “SD” is selected as the control means to automatically 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
•
•
•
1.
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 software 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.
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:

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 converter is required for the RS232 Serial Comm Port of the IBM PC. The EC485 converter should be wired in the following manner:

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 controls as well. However, the EC485 converter can be used to communicate only with the E340 controls.
