D7 (DIO7 Configuration) Command
<I/O Settings> The D7 command is used to
select/read the behavior of the DIO7 line (pin 12).
Options include:
" CTS flow control
" Analog-to-digital converter
" Digital input
" Digital output
D8 (DI8 Configuration) Command
<I/O Settings> The D8 command is used to
select/read the behavior of the DI8 line (pin 9).
This command enables configuring the pin to
function as a digital input. This line is also used
with Pin Sleep.
DA (Force Disassociation) Command
<(Special)> The DA command is used to immedi-
ately disassociate an End Device from a Coordi-
nator and reattempt to associate.
DB (Received Signal Strength) Command
<Diagnostics> DB parameter is used to read the
received signal strength (in dBm) of the last RF
packet received. Reported values are accurate
between -40 dBm and the RF module's receiver
sensitivity.
Absolute values are reported. For example: 0x58 = -88 dBm (decimal). If no packets have been
received (since last reset, power cycle or sleep event), 0 will be reported.
DH (Destination Address High) Command
<Networking {Addressing}> The DH command is
used to set and read the upper 32 bits of the RF
module's 64-bit destination address. When com-
bined with the DL (Destination Address Low)
parameter, it defines the destination address used
for transmission.
An module will only communicate with other
modules having the same channel (CH parame-
ter), PAN ID (ID parameter) and destination address
(DH + DL parameters).
To transmit using a 16-bit address, set the DH parameter to zero and the DL parameter less than
0xFFFF. 0x000000000000FFFF (DL concatenated to DH) is the broadcast address for the PAN.
Refer to the XBee/XBee-PRO Addressing section for more information.
