Gateway CAN
Gateway uses the vehicle data bus (CAN) as the on-truck path between mounted equipment and the apparatus.
This page is the highest-priority developer shell. It lists the sections a specification will need. It does not publish identifiers, parameter groups, bit rates, or database files.
No CAN IDs, PGNs, baud rates, DBC files, or example frames are available on this site.

Foundation
How a unit is addressed on the bus, how it joins, and what “present” means.
Addressing, timing, and required baseline behavior are not published.
Identity
How a reader knows which product and which unit it is talking to.
Identity fields and encoding are not published.
Operating state
A short, operator-useful state (for example: running, idle, needs attention) — not a full data dump.
State names, transitions, and priority are not published.
Telemetry
Values that may later appear in a summary view. Cloud or command display is not required for the equipment to work.
Signal lists, units, and update rates are not published.
Diagnostics
Faults and service information that a technician can act on.
Fault codes and diagnostic sessions are not published.
Commands
Optional writes to equipment. Higher risk than telemetry.
Command names, payloads, and authorization are not published. Any future command path must fail safe and must not be required for primary function.
