0x4B Report Packet 4B
Machine/Code ID and Additional Status Report
The receiver transmits this packet in response to packets 25 and 26
and following a change in state. This packet identifies the receiver
and may present error messages. Packet 46 is always sent with this
packet. 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.
The status codes are encoded into individual bits within the bytes.
The bit positions and their meanings are shown below.
