      Series 90-30 SNP to RS-232 Adapter

      HE693SNP232A

      Product Information:

      HE693SNP232A is a SNP-to-RS-232 adapter for a compatible GE Series 90-30 PLC programmer port. Its 15-pin connector interfaces with the SNP/RS-422 programmer port and provides a 9-pin RS-232 connection for a programming device. The adapter is powered by the PLC port and draws up to 100 mA at 5 V DC. Confirm connector pinout, CTS/RTS handshaking, cable wiring and serial settings before testing communications.

        • PRODUCT OVERVIEW

          What is this product?

          The HE693SNP232A is a legacy serial interface accessory for connecting a GE Series 90-30 SNP programming interface to an RS-232 device. Horner documentation describes a 15-pin SNP-side connection and a 9-pin RS-232-side connection, with the adapter powered from the PLC port. It provides an interface for a documented SNP connection; it is not a PLC CPU, general-purpose protocol converter or substitute for a verified programming cable. Before reuse, confirm the complete part number and revision, connector pinout, cable assembly, PLC port settings and the programming device’s serial configuration against the applicable Horner instructions.

      Information

      Overview Manuals Signal Conversion Cable Matching Commissioning

      Features:

      • Provides the documented RS-422 SNP to RS-232 serial interface for compatible GE Series 90-30 programming connections.
      • Connects at the PLC’s 15-pin D-type serial port and presents the documented RS-232-side connection for the programming device.
      • The adapter is powered from the PLC interface; confirm the exact cable, pinout and serial settings rather than treating it as a universal converter.
      The HE693SNP232A is a legacy serial accessory used to connect a compatible RS-232 programming device to a Series 90-30 PLC SNP interface. It performs the documented electrical/interface conversion and is not a CPU or standalone protocol gateway.

      Before reuse, check the full part number and revision, both connector pinouts, cable assembly, PLC port configuration and programming-device settings against the Horner instructions. Confirm the connected device supports the required serial interface and SNP communication.

      The OEM lifecycle status of HE693SNP232A is not confirmed in the currently available Horner documentation. Moore Automated can check for compatible replacement modules and spare parts, subject to exact interface requirements, stock confirmation and written quotation.
      GE / Horner HE693SNP232A SNP-to-RS-232 Adapter Installation Manual (MAN0079), Link Important Notice: Confirm the 15-pin SNP port, 9-pin RS-232 pinout, cable wiring and serial settings before communication tests.

      Signal conversion

      • PLC side: 15-pin SNP / differential RS-422 interface
      • Device side: 9-pin RS-232 interface
      • Power: supplied by the PLC programmer port, 100 mA maximum at 5 V DC
      • RS-232 signals: TXD, RXD, GND, CTS and RTS

      Cable matching

      The documented 9-pin RS-232 pinout permits a straight-through 1:1 connection to a compatible PC serial port. Confirm whether the connected device uses hardware handshaking before selecting the cable.

      Check connector gender, TXD/RXD direction, CTS/RTS requirements and shield/ground practice against the receiving device documentation.

      Communication checks

      • Power down the PLC rack before fitting or removing the adapter.
      • Inspect the 15-pin programmer port and connector alignment.
      • Confirm the RS-232 cable and hardware-handshaking signals.
      • Restore power and verify baud rate, parity and serial communication.
      • Document the working cable and port settings for future replacement.

      Technical notes

      Connect the 15-pin SNP plug only to a compatible GE Series 90-30 programmer port. The adapter draws up to 100 mA at 5 V DC from that port. Confirm the 9-pin RS-232 pinout, CTS/RTS hardware handshaking, baud rate and cable wiring before communication tests.

      SNP Serial Interface

      HE693SNP232A provides the documented SNP serial interface for compatible GE Series 90-30 programmer-port connections. Verify the CPU port, connector and cable pinout, serial settings and controller configuration before communication testing.

      Signal Verification

      Confirm that the PLC-side port is the 15-pin SNP programmer interface and that the connected device uses the required 9-pin RS-232 pinout. Verify baud rate, parity and cable wiring before communication tests.
