Description
章节标题：“Description”Key Box 36 carries its isolated, NMEA 2000-ready CAN2 on AMPSEAL J2 pins 29-35. An NMEA 2000 device drops onto the backbone through the standard Micro-C (M12 A-coded 5-pin) connector, and certification needs that connector. The owner chose a standard N2K socket on the box for the existing CAN2 (2026-10-22), keeping 36 keys.
Acceptance:
- CAN2 leaves the box through a panel-mount M12 A-coded 5-pin male socket on the lid (pin 1 shield, 2 NET-S, 3 NET-C, 4 NET-H, 5 NET-L), wired to a board header J7 in the isolation island; J2 pins 29-32 and 34-35 become spare, AUX2 stays on pin 33; no termination inside the box.
- Schematic ERC 0; PCB DRC 0 unconnected / 0 clearance / 0 short; renders and STEP show the N2K socket; Key spec, design appendix, guide and the key-box README follow.
