9XTend™ OEM RF Module ‐ Product Manual v2.x4x [2007.01.04]
DT (Destination Address) Command
E0 (Echo Off) Command
E1 (Echo On) Command
ER (Receive Error Count) Command
FH (Force Wake-up Initializer) Command
<Networking & Security> DT Command is used to
set/read the networking address of an RF module.
The modules utilize three filtration layers: Vendor
ID Number (ATID), Channel (ATHP), and Destina-
tion Address (ATDT). The DT command assigns an
address to a module that enables it to communi-
cate only with other modules having the same
address. All modules that share the same DT
parameter can communicate with each other.
RF modules in the same network with a different
destination address (than that of the transmitter) will listen to all transmissions to stay synchro-
nized, but will not send any of the data out their serial ports.
Refer to the ‘Addressing’ section [p44] for more information.
<Command Mode Options> E0 Command turns
off character echo in AT Command Mode.
By default, echo is off.
<Command Mode Options> E1 Command enables
character echo in AT Command Mode. Each typed
character will be echoed back to the terminal
when ATE1 is active. E0 (Echo Off) is the default.
<Diagnostics> The ER command is used to set/
read the number of receive-errors. The error
count records the number of packets partially
received then aborted on a reception error. This
value returns to 0 after a reset and is not non-
volatile (Value does not persist in the module's
memory after a power-up sequence). Once the
Receive Error Count reaches its maximum value
(up to 0xFFFF), it remains at its maximum count
value until the maximum count value is explicitly changed or the module is reset.
The ER parameter is not reset by pin, serial port or cyclic sleep modes.
<Sleep (Low Power)> The FH command is used
to force a Wake-up Initializer to be sent on the
next transmission. Use only with cyclic sleep
modes active on remote modules.
ATFH will not send a long header if ATHT = 0xFFFF. WR (Write) Command does not need to be
issued with FH Command.
