Serial Level Conversion and Industrial Control Compatibility
The IC690ACC901 contains the signal-conversion electronics within the connector/cable assembly. The PC side accepts RS-232 signals through the DB-9 interface, while the PLC side provides differential serial communication through the 15-pin D-sub SNP port.
Operating power is obtained from Pin 5 of the PLC serial port at +5 VDC. No external power adapter is specified. The converter supports SNP and SNP-X communications at rates up to 19,200 bps.
No separate firmware interface or firmware flash update function is identified in the supplied specifications. Firmware compatibility should therefore be determined by the connected GE PLC, programming software, and communication protocol rather than by an undocumented converter firmware feature.
Frequently Asked Questions
Q: What electrical interfaces are converted by the IC690ACC901?
A: The converter provides bidirectional conversion between RS-232 on the PC side and differential RS-485/RS-422 signaling on the GE PLC side.
Q: How is the converter powered?
A: The IC690ACC901 receives +5 VDC directly from Pin 5 of the PLC 15-pin serial port. The specified power consumption is approximately 100 mA.
Q: Which serial protocols are supported?
A: The supplied specifications identify GE SNP (Series Ninety Protocol) and SNP-X. The specified communication rate is up to 19,200 bps.
Field Installation Guidelines
Connect the DB-9 female connector to the host computer serial interface.
Connect the DB-15 male connector to the compatible GE PLC serial port.
Verify that the PLC serial port provides the specified +5 VDC supply on Pin 5 before energizing the converter.
Route the serial cable separately from high-current motor, contactor, and switching-power wiring where practical.
Avoid unnecessary cable loops and sharp bends that can impose mechanical stress on the connector assembly.
Where shielded serial cabling is used, terminate the shield according to the PLC cabinet grounding scheme and avoid creating unintended ground-current paths.
Confirm the PLC serial port configuration and SNP or SNP-X communication parameters before initiating programming or monitoring operations.
Do not apply an external power source unless specifically supported by the equipment documentation.
Disconnect power before changing the PLC-side connector where the installation procedure or equipment documentation requires a de-energized connection.
