- Documented converter for RS-232 equipment connected to a Series 90-30 serial port
- Used with the PLC's 15-pin RS-422-compatible connector
- Supports the physical connection required for SNP serial communication
HE693SNP232A is the Horner APG converter referenced for a Series 90-30 PLC serial connection.
It bridges the different RS-232 and RS-422 electrical interfaces while leaving the communicating devices responsible for compatible SNP protocol settings.
Before use, identify the PLC power-supply connector, verify the cable pinout and direction, and match all serial parameters at both endpoints.
Availability, condition, price, and shipping time for HE693SNP232A are confirmed during quotation.

- Connect the converter to the documented 15-pin Series 90-30 serial port
- Match the converter cable pinout to the RS-232 endpoint
- Verify signal ground and accessory-power conductors before energizing
- Configure both endpoints for the same SNP communication mode
- Match baud rate, framing, and addressing across the link
- Confirm that conversion changes the electrical interface rather than the serial protocol
- Check converter power when neither endpoint receives data
- Trace transmit and receive conductors when communication is one-way
- Compare the installed connector orientation with the official Series 90-30 pinout
- SNP communication between an RS-232 programming system and a Series 90-30 PLC
- Serial connection of compatible RS-232 operator or service equipment to a Series 90-30 PLC
