Determines if the GO0 & GO1 server as generic output or as
protocol status.
Specifies the number of hops a transceiver stays in session
with another transceiver
The random amount of time a transceiver waits when a
collision occurs before resending the packet again.
0x00: Disable Random Backoff
0x01: Wait 1-2 packet times, then retry
0x03: Wait 1-4 packet times, then retry
0x07: Wait 1-8 packet times, then retry
0x0F: Wait 1-16 packet times, then retry
0x1F: Wait 1-32 packet times, then retry
0x3F: Wait 1-64 packet times, then retry
0x7F: Wait 1-128 packet times, then retry
0xFF: Wait 1-256 packet times, then retry
The minimum RSSI required by a transceiver to establish a
session upon hearing a long beacon.
