RS-485 Control

No special software is required to control the RS-485 receiver or transmit line driver. The driver is

automatically enabled during each byte transmitted in RS-485 mode. The transmitter is always

enabled in RS-422 mode. The receiver is tri-stated during each byte transmitted in the echo-off

mode. The receiver is always enabled in the echo-on mode. There are 4.7k Ohm pull-up/pull-down

resistors on the RDA and RDB lines. A termination resistor is usually not necessary but may be

added if needed.

Dip Switch Set-up

Dip switches allow the UC485 module to be configured for two-wire or four-wire, RS-422 or RS-

485 modes. In two-wire mode the TDA(-) and RDA(-) are tied together so are TDB (+) and RDB

(+), making multi-dropping the UC485 converter into an existing network easy.

For use with Fireye equipment it is recommended to have all dip switches set to the ON position.

INSTALLATION FOR WINDOWS

CUSTOMIZING BurnerLogix YZ300 OR FLAME-MONITOR E300 MESSAGES

You can customize the recycle and lockout alarm message associated with each pair of terminals of

the E300 Expansion Module and YZ300 Interlock Annunciator. Each customized message can be up

to 40 characters in length.

The following equipment is required:

A Windows compatible PC with E300 (Flame-Monitor) or YZ300P (BurnerLogix) programming

software.

UC485 USB to RS485 converter with USB cable.

ED612 with RJ12 connector mounted and wired into terminal block of the UC485.

For E300 messages, an EP programmer with an engineering code of 28 or later.

For BurnerLogix, a YZ300 Interlock Annunciator.

#2. The screen above appears. Make sure Install

the software automatically is selected. Then

select the Next> button.

You may be prompted to BROWSE the CD to

select the correct folder that contains the

proper driver.

#1. Plug the UC485 into an available USB

port on your Windows compatible computer

or connected hub. The screen above appears,

telling you that there is a new device plugged

into the USB bus. Click on No, not this time,

then the Next> button.

#3. The screen above will appear. Click the

Finish button to complete the installation. #4. Continue to install the serial port in the

same way as installing the converter. Click

the Next button followed by the Finish but-

ton. It takes a couple of seconds for the serial

port to be installed.



1. Connect the UC485 converter to an available USB port of a Windows compatible computer.

FIGURE 1. .

2. Connect the ED612 (RJ12 female connector provided with the UC485) to terminals TD(A),

TD(B), RD(A), and RD(B) on the UC485

3. Plug one end of the ED512-2, -4, -8 cable into the jack on the ED612 and the other end into

either of the jacks located on the EP programmer for a FLAME-MONITOR system or directly

into the YZ300 for a BurnerLogix system.

For complete details on customizing the E300 messages, refer to bulletin E-3001.

For complete details on customizing the YZ300 messages, refer to bulletin YZEM-3001.

COMMUNICATING WITH 45FS1/45UVFS1 SIGNATURE SCANNERS OR 95IRS2/95UVS2/95DSS2 AND

95DSS3 INSIGHT II FAMILY OF INTEGRATED SCANNERS OR PARAGON 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 a

Windows compatible PC is required for communicating with the flame scanners.

Since the flame scanners communicate over the data link via RS485, the UC485 USB/RS485 con-

verter is required for the communications Port of the PC. The UC485 converter is wired in the fol-

lowing 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.

Wire the UC485 converter to the E340 controls in the following manner:
