SEA Praha D-RFID-PR3 Quick Manual

D-RFID-PR3 Manual
1. Introduction
D-RFID-PR3 (PR3 for short) is external RF receiver module for PLC FATEK. PR3
receives codes from 433 MHz transmitters (in system SEA D-RFID) and sends
them to RS485 serial channel (9600 Baud, 7 bits, even parity, 1 stop bit) in protocol
FATEK.

Main Features

External RF receiver module for PLC FATEK

RF Data coding - system SEA D-RFID

Operates in free 433 MHz band

Serial communication: RS485 – FATEK protocol

2. Package
1 pc PR3 (order code D-RFID-PR3)
Warning
Transmitter D-RFID and PLC FATEK are not part of PR3 package and
has to be ordered separately. PR3 can be connected to any PLC FATEK,
which is equipped with RS 485 communication port (e.g. FAC-FBS-CB5). PR3
accepts only RF signals transmitted in system SEA D-RFID (e.g. D-RFID which can
transmit codes for 2 year on internal battery).
3. Typical application
4. Installation
1. Connect PR3 to PLC and switch on the power supply. All LEDs on PR3 are
dark. (In case the red LED lights, check the PLC serial port 3 setting
(9600Bd, even parity, 1 stop bit), if it does not help, try to exchange A and
B RS485 wires).
2. Locate the D-RFID transmitter near PR3. The green LED RF diode on PR3
starts to blink once per 10 sec.
3. Test the simple PLC program using WinProladder. (see the simple example
at the end of this document)
