PK (RF Packet Size)
Command
<Serial Interfacing> Set/Read
the maximum size of the RF
packets sent out a transmitting
module. The maximum packet
size can be used along with
the RB and RO parameters to
implicitly set the channel dwell
time.
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.
PW (Pin Wake-up) Command
<Sleep (Low Power)> Under
normal operation, a module in
Cyclic Sleep Mode cycles from
an active state to a low-power
state at regular intervals until
data is ready to be received. If
the PW Parameter is set to 1,
SLEEP (pin 2) can be used to
wake the module from Cyclic
Sleep. If the SLEEP pin is de-
asserted (low), the module will
be fully operational and will not
go into Cyclic Sleep. Once
SLEEP is asserted, the
module will remain active for the period of time specified by
ST (Time before Sleep) Command and will return to Cyclic Sleep Mode (if no data is
ready to be transmitted). PW Command is only valid if Cyclic Sleep has been
enabled.
RB (Packetization
Threshold) Command
<Serial Interfacing> RF
transmission will commence
when data is in the DI Buffer
and either of the following
criteria are met:
RO times out on the UART
receive lines
(ignored if RO = 0)
RB characters have been
received by the UART
(ignored if RB = 0)
If PK is lowered below the value of RB; RB is automatically lowered to match PK.
