Selection Suggestions and Precautions
Selection Suggestions:
- Use this adapter when you need to connect a standard RS-232 device (PC serial port) to the Series 90-30 programming port.
- Confirm that the PLC power supply has the standard 15-pin SNP programming port.
- For modern PCs without serial ports, pair this adapter with a quality USB-to-RS-232 converter.
- Check the revision letter (R) if matching an existing unit is required.
Precautions:
- Power is limited (max 100 mA @ 5 VDC) — do not connect devices that draw excessive current.
- Use the correct cable pinout; improper wiring can prevent communication.
- Avoid hot-plugging under certain conditions; follow GE Fanuc / Horner guidelines.
- Ensure proper grounding to minimize noise on the serial link.
- This is an adapter only — it does not replace a full programming cable in all situations.
- Verify compatibility with the specific programming software version being used.
