DT (Destination Address) Command
<Networking & Security> DT Command is used to
set/read the networking address of an RF
modem. The modems utilize three filtration lay-
ers: Vendor ID Number (ATID), Channel (ATHP),
and Destination Address (ATDT). The DT com-
mand assigns an address to a modem that
enables it to communicate only with other
modems having the same address. All modems
that share the same DT parameter can communi-
cate with each other.
AT Command: ATDT
Binary Command: 0x00
Parameter Range: 0 - 0xFFFF
Default Parameter Value: 0
Number of bytes returned: 2
Related Commands: HP (Hopping Channel), ID
(Modem VID), MK (Address Mask), MY (Source
Address)
RF modems in the same network with a different destination address (than that of the transmitter)
will listen to all transmissions to stay synchronized, but will not send any of the data out their
serial ports.
E0 (Echo Off) Command
<Command Mode Options> E0 Command turns
off character echo in AT Command Mode.
By default, echo is off.
E1 (Echo On) Command
<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.
ER (Receive Error Count) Command
<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 modem's
memory after a power-up sequence). Once the
Receive Error Count reaches its maximum value
AT Command: ATE0
Binary Command: 0x0A (10 decimal)
AT Command: ATE1
Binary Command: 0x0B (11 decimal)
AT Command: ATER
Binary Command: 0x0F (15 decimal)
Parameter Range: 0 - 0xFFFF
Default Parameter Value: 0
Number of bytes returned: 2
Related Commands: GD (Receive Good Count)
(up to 0xFFFF), it remains at its maximum count
value until the maximum count value is explicitly changed or the modem is reset.
The ER parameter is not reset by pin, serial port or cyclic sleep modes.
FH (Force Wake-up Initializer) Command
<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
AT Command: ATFH
Binary Command: 0x0D (13 decimal)
modes active on remote modems.
ATFH will not send a long header if ATHT = 0xFFFF. WR (Write) Command does not need to be
issued with FH Command.
