Features:
- Connects a SmartStack controller to an engine control module.
- Provides separate transmit and receive activity indicators.
- Exchanges up to 128 sixteen-bit controller words.
The Horner HE800JCM100 dedicates its primary serial connector to engine communications, separating this task from ordinary controller programming ports.
Its paired RS-232 paths and directional LEDs help isolate whether a communication loss originates in transmitted requests, received responses or cable assignment.
Register capacity is split evenly between input and output data, so the controller project should preserve the manual's 64-word boundaries when rebuilding an application.
The Horner HE800JCM100 Engine Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Engine Link: The primary 9-pin RS-232 port is intended for the engine control module, so replacement wiring should follow the application pinout rather than a generic PC cable.
- Second RS-232 Path: A separate serial channel supports the module's documented data flow and gives troubleshooting a distinct connection to test.
- Reserved Interface: The RS-485/422 connection is present but unused by this application, preventing an unsupported port from being mistaken for an active network.
- Input Area: Up to 64 sixteen-bit %AI words carry information toward the controller, allowing multi-value engine records to remain grouped.
- Output Area: A matching block of 64 sixteen-bit %AQ words carries controller data in the opposite direction, so both mappings must be kept in step.
- Project Alignment: Register addresses should be checked against the engine application before download because a shifted block can produce valid-looking but incorrect values.
- Transmit View: The green TX indicator shows that the module is placing data on a serial path, helping distinguish software silence from a missing reply.
- Receive View: The red RX indicator confirms returning serial activity and can expose one-way cabling or protocol problems.
- Directional Diagnosis: Comparing both indicators during a command cycle narrows troubleshooting before controller registers or engine settings are changed.
- Engine Monitoring: The module suits controller projects that must bring structured engine information into an OCS or RCS data area.
- Command Exchange: Separate input and output word blocks support applications that both read operating data and send permitted control values.
- Legacy Replacement: Matching the D-sub wiring and register map lets an existing machine retain its established engine interface behavior.
