GE Fanuc IC690ACC901 DB9 Programming Cable for 90-70 90-30 Series

Product Summary

The IC690ACC901 is a Miniconverter Kit designed for communication between GE Fanuc Series 90 programmable logic controllers and RS-232 compatible devices such as programming computers or terminals. It converts RS-422 (SNP) signals to RS-232.

Core Specifications

• Model Number: IC690ACC901
• Kit Contents: RS-422 to RS-232 Miniconverter, 2 m (6 ft) serial extension cable, 9-pin to 25-pin converter plug
• Compatible Systems: Series 90-30, Series 90-70, Series 90-20 (SNP port)
• Power Supply: +5 VDC from PLC serial port (no external power required)
• Current Draw: Version A: 150 mA typical; Version B: 100 mA typical

Electrical & Interface Characteristics

• RS-422 Side: 15-pin D-shell male connector (direct connection to PLC SNP port)
• RS-232 Side: 9-pin D-shell male connector
• Maximum Baud Rate: 38.4 kbaud
• Standards: EIA-422 (balanced) or EIA-423 (unbalanced)
• Ground Isolation: None provided
• Operating Temperature: 0°C to 70°C

Installation Guide

1. Connect the 15-pin connector of the Miniconverter directly to the PLC SNP serial port.
2. Attach the extension cable to the 9-pin RS-232 connector on the Miniconverter.
3. Connect the other end of the cable to the RS-232 port of the programming computer (use the 9-to-25 pin adapter if required for older PCs).
4. Configure the programming software for SNP protocol and the appropriate baud rate.
5. Verify communication through the programming software.

Selection Guidelines

• Use IC690ACC901 for direct serial programming and monitoring of Series 90 PLCs via RS-232 computers.
• For applications requiring ground isolation or longer distances, consider the IC690ACC903 Port Isolator.
• For modern USB-based programming, evaluate equivalent USB-to-SNP solutions.
