The target remote will issue a DiscoverReply command as follows:
0xFB 0x08 0x16 0x00 0x02 0x01 0x00 0x01 0x01 0xFF
The 0x00 Status byte value indicates a response from the remote. The tree-routing system address of the
target remote is received in Little-Endian byte order, so the address is 0xFF0101. Referring to Figure
2.12.1.2, this is the system address of Remote R1.

4.2 Configuration Registers
The configuration registers supported by the CCT24 are described below. Registers are sorted into banks
according to similar functions. Default register values are in bold. All changes to parameters are tempo-
rary and will not persist through power cycling until 0x01 has been written to the MermorySave parameter
in Bank FF. Writing 0x00 to the MemorySave parameter will reload the factory default values which also
require writing 0x01 to the MemorySave location. Also note that some parameter changes do not take
effect until they are saved and the module is reset or power cycled. Modules can be reset by writing 0x00
to the UcReset parameter in Bank FF.

DeviceMode - selects the operating mode for the radio: remote, base, PTT remote (listen mostly remote)
or tree-routing router. Note that changing this setting does not take effect immediately. It must be followed
by a MemorySave command (See Section 4.2.9) and then a hardware reset.
