MY (Source Address) Command
<Networking and Security> The MY command is used to set/read the Source Address of the RF modem.
NB (Parity) Command
<Serial Interfacing> The NB command is used to select/read the parity settings of the RF modem for UART
communications.
PB (Polling Begin Address) Command
<Networking and Security> PB command is used to set/read the modem’s Polling Begin Address - the first address
polled Polling Mode is enabled.
Polling Operations: The ‘Polling Base’ (MD = 3) cycles through a sequential range of addresses, polling each ‘Polling
Remote’ (MD = 4). The base then waits for a response and proceeds to the next ‘Polling Remote’. Each ‘Polling
Remote’ responds by sending the data from the Data In buffer following the RB and RO parameters. When there is no
eligible data to send, the ‘Polling Remote’ will not respond. The ‘Polling Base’ will move to the next address in the
polling sequence after a short delay.
