Command
Interpreter
WriteConfigNew_Request(0x71)
[Config data error| Command not allowed| Test mode]
WriteConfigNew_Error (0x73)
On success,
mode is changed
to Master, Slave
or Spy
[Config data OK&& Command allowed&& !Test mode]
WriteConfigNew_Confirm (0x72)
Figure 32. Sequence Diagram for WriteConfig_Request
Command can be issued at any time (If the status message allows it to be send) and will bring the MODEM in a ‘SET’ state
if the configuration data is correct. Depending on the configuration data, the final state of the MODEM will be Master, Slave
or Monitor.
