NB (Parity) Command
<Serial Interfacing> Select/Read parity settings
for UART communications.
PK (Maximum RF Packet Size) Command
<RF Interfacing> PK Command is used to
set/read the maximum size of RF packets. The
maximum packet size can be used along with
RB/RO to implicitly set the channel dwell time.
If PK is set above 256 and BR is subsequently
changed to 0, then PK will automatically be
lowered to 256 and a warning will be raised (see
BR (RD Data Rate) and WN (Warning Data)
Commands for details).
Changes to this parameter may have a secondary effect on the RB (Packet Control Characters)
Parameter. RB must always be less than or equal to PK. If PK is changed to a value less than the
current value of RB, RB is automatically lowered to be equal to PK.
* When BR = 0, the maximum PK value is 0x100 (256d). When BR = 1, the maximum PK value
is 0x800 (2048d).
PL (Power Level) Command
<RF Interfacing> PL Command is used to
set/read the power level at which the modem
transmits.
