User Manual - QG65N2 SAE J1939 Inclinometer (Type JB) V1.1

All requested devices send their ACMs so that you know which devices are currently on the network.

Any CA that is unable to successfully claim an address shall respond with a Cannot Claim Address message. It has
the same PGN as ACM but has a source address of 254d (the NULL address).
