TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP)
Report Packet 0x4B - Machine/Code ID and Additional Status
The receiver transmits this packet in response to packets 0x25 and 0x26 and following
a change in state. In conjunction with Packet 0x46, “health of receiver,” this packet
identifies the receiver and may present status messages. The machine ID can be used
by equipment communicating with the receiver to determine the type of receiver to
which the equipment is connected. Then the interpretation and use of packets can be
adjusted accordingly.
