P0 (PWM0 Configuration) Command
<I/O Setting {I/O Line Passing}> The P0 com-
mand is used to select/read the function for
PWM0 (Pulse Width Modulation output 0). This
command enables the option of translating
incoming data to a PWM so that the output can be
translated back into analog form.
With the IA (I/O Input Address) parameter cor-
rectly set, AD0 values can automatically be
passed to PWM0.
P1 (PWM1 Configuration) Command
<I/O Setting {I/O Line Passing}> The P1 com-
mand is used to select/read the function for
PWM1 (Pulse Width Modulation output 1). This
command enables the option of translating
incoming data to a PWM so that the output can be
translated back into analog form.
With the IA (I/O Input Address) parameter cor-
rectly set, AD1 values can automatically be
passed to PWM1.
PL (Power Level) Command
<RF Interfacing> The PL command is used to
select and read the power level at which the RF
module transmits conducted power.
WHEN OPERATING IN EUROPE:
XBee-PRO RF Modules must be configured to
operate at a maximum transmit power output
level of 10 dBm. The PL parameter must equal 0
(10 dBm).
Additionally, European regulations stipulate an
EIRP power maximum of 12.86 dBm (19 mW) for
the XBee-PRO and 12.11 dBm for the XBee when
integrating high-gain antennas.
WHEN OPERATING IN JAPAN:
XBee-PRO RF Modules optimized for use in Japan contain firmware that limits transmit power out-
put to 10 dBm. If PL=4 (default), the maximum power output level is 10 dBm. For a list of module
part numbers approved for use in Japan, contact MaxStream [call 1-801-765-9885 or send e-mail
to sales@maxstream.net].
