        Features:

        • Communicates on SAE J1939 vehicle control networks.
        • Uses 29-bit CAN 2.0B message identifiers.
        • Separates scanned data from transmit channels.
        The Horner HE800JCM200 brings heavy-vehicle parameter groups into a SmartStack control project without converting the bus to a general serial protocol.

        Scanning is suited to values that must be refreshed as network traffic arrives, whereas transmit channels organize the messages the controller is responsible for producing.

        Because the module address and bit rate are fixed, integration effort belongs in PGN selection, timing and destination behavior rather than basic bus-speed tuning.

        The Horner HE800JCM200 SAE J1939 Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        HE800JCM200 SAE J1939 Communication Module Manuals, Datasheets, Links 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.
        • Extended Frames: The module interprets 29-bit CAN identifiers, preserving the priority, parameter group and addressing fields used by J1939 devices.
        • Fixed Bus Rate: Operation at 250 kbit/s must match the existing vehicle backbone, so an incompatible segment speed cannot be corrected in the PLC project.
        • Source Address: Address 251 is fixed for this module and should be checked against the network design to prevent address conflicts.
        • Scanning: The scanning method keeps selected network parameters available to controller logic without requiring a separate ladder request for every update.
        • Transmit Channels: Dedicated channels define outbound J1939 traffic, making application-owned messages easier to schedule and maintain.
        • Method Choice: Selecting the method by data direction avoids treating received PGNs and generated PGNs as one undifferentiated register block.
        • Module Health: Green indication reports that the module is operating, providing a first check before network configuration is investigated.
        • Bus Activity: Orange flashes reflect J1939 traffic and help show whether frames are reaching the interface.
        • Combined Reading: A healthy LED with no traffic points toward bus wiring or network silence, while missing health indication shifts attention to the stack.
        • Vehicle Telemetry: Scanned PGNs can bring engine and chassis operating values into alarms, displays or coordinated control logic.
        • Mobile Equipment: CAN-based machinery can exchange selected J1939 information with a SmartStack controller while retaining the established vehicle bus.
        • Message Generation: Transmit channels support controller-originated parameter groups where the J1939 application assigns that responsibility.
        Description
        For truck, bus and mobile-equipment control networks, the Horner HE800JCM200 adds an SAE J1939 interface to a compatible SmartStack controller. It uses the 29-bit identifier format defined by CAN 2.0B and operates at the J1939 network rate of 250 kbit/s.

        Incoming parameter groups can be collected through the module's scanning method, while selected values may be issued through transmit channels. That separation lets a controller project organize continuously monitored traffic independently from messages that must be generated by the application.

        The module uses the fixed J1939 source address 251 and provides a bi-color indication for module condition and bus activity. When introducing the Horner HE800JCM200 to an established vehicle network, PGN selection, destination behavior and update timing should be reviewed together to avoid missing or competing messages.

        Technical notes
        Horner HE800JCM200 operates on a 250 kbit/s SAE J1939 network with a fixed source address of 251. The module separates monitored traffic from application transmit channels.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why does Horner HE800JCM200 show network traffic but no usable values?
        Horner HE800JCM200 may see frames that do not match the configured PGNs; verify the parameter group, source or destination criteria and the assigned controller registers.
        Can Horner HE800JCM200 join a J1939 segment running at another CAN rate?
        Horner HE800JCM200 is fixed at 250 kbit/s, so the connected segment must use the same rate or be separated through an appropriate gateway.
        How should received data be organized on Horner HE800JCM200?
        Use the Horner HE800JCM200 scanning method for PGNs that must be monitored continuously, then map each selected parameter to the intended controller data area.
        What can cause an address conflict with Horner HE800JCM200?
        Horner HE800JCM200 uses fixed source address 251; another active node claiming the same address can disrupt message ownership and should be identified in the network plan.
        When should a transmit channel be used on Horner HE800JCM200?
        A Horner HE800JCM200 transmit channel is appropriate when the controller must originate a defined J1939 message at an application-controlled rate rather than only monitor bus traffic.
        How do the indicators help diagnose Horner HE800JCM200?
        Horner HE800JCM200 uses green for module condition and orange flashes for network traffic, so stack health and bus activity can be evaluated separately.
