Horner APG HE693SNP232A is an RS-232 to RS-422 interface converter used to connect an RS-232 host to the SNP serial port of a compatible Series 90-30 controller.
The controller serial port uses an RS-422 physical interface and a 15-pin D-type female connector; the converter provides the electrical interface required by an RS-232 programming or communication device.
Before replacement, verify the HE693SNP232A label, controller and power-supply type, cable pinout, grounding, host serial settings, SNP address, baud rate and communication test procedure.

Horner APG HE693SNP232A converts an RS-232 host interface to the RS-422 electrical interface used by the compatible Series 90-30 SNP serial port.
Horner APG HE693SNP232A is documented for SNP communication, so the host software, station address and serial parameters must match the controller configuration.
The controller port is electrically RS-422, so an RS-232 computer requires Horner APG HE693SNP232A or an approved equivalent interface before the devices can communicate.
Horner APG HE693SNP232A interfaces with the documented 15-pin D-type female serial connector on the compatible controller power supply through the correct cable and pinout.
A generic serial adapter should not replace Horner APG HE693SNP232A unless RS-232 and RS-422 signaling, connector pinout, handshake behavior, grounding and SNP operation are verified.
Commission Horner APG HE693SNP232A by checking cable continuity and grounding, matching baud rate and SNP settings, then proving stable upload, download or data communication.
Provide the complete Horner APG HE693SNP232A label, controller and power-supply numbers, host interface, cable and connector photographs, quantity and destination.
Send the complete HE693SNP232A catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before quotation.
