Compatibility description: 502-03549-02 belongs to Fives Group CNC communication board family. Compatible with Fives Group CPU, memory boards and other rack modules. Widely fitted on heavy Fives Group horizontal boring mills.

Function

Function description: 502-03549-02 is serial communication board manufactured by Fives Group. It establishes serial data link between CNC controller and external peripherals such as program readers and data terminals. It supports CNC part program import and export, and uploads machine alarm and status data for remote troubleshooting. Built-in surge suppression protects communication circuit from electrical interference. It is legacy serial communication spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off rack +5V backplane power. Insert 502-03549-02 board into rack slot and secure gold finger connector. Wire serial communication cable to the signal terminal. Configure baud rate and communication parameters via CNC software. Power on rack, verify TX and RX LED indicators, perform loopback test and test program transfer function.

Interface

Interface list: Backplane gold finger connector, serial signal screw terminal block,on-board POWER / TX / RX / FAULT LED indicators for Fives Group 502-03549-02.

Diagnostic

Troubleshooting: Cannot transfer program: Check cable wiring, baud rate mismatch or faulty transceiver chip. FAULT LED lit: Backplane communication failure or serial port short-circuit. Intermittent data loss: Electromagnetic interference, poor grounding or aging buffer chip.
