DT (Destination Address)
Command
<Networking & Security> DT
Command is used to set the
networking address of an Zlinx
Module. Zlinx Modules use three
filtration layers: Channels
(ATHP), Vendor Identification
Number (ATID) and Destination
Addresses (ATDT). DT
Command assigns an address to a module that enables it to communicate only with
other modules having the same addresses. All modules that share the same
Destination Address can communicate freely with each other. Modules 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> The
E0 command turns off character
echo in AT Command Mode.
By default, echo is off.
E1 (Echo On) Command
<Command Mode Options> E1
Command turns on the echo in
AT Command Mode. Each
typed character will be echoed back to the terminal when ATE1 is active. E0 is the
default.
ER (Receive Error Count)
Command
<Diagnostics> Set/Read the
receive error count. The error-
count records the number of
packets partially received then
aborted on 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.

FH (Force Wake-up Initializer)
Command
<Sleep (Low Power)> FH
Command is used to force a Wake-up Initializer to be sent on the next transmission.
WR (Write) Command does not need to be issued with FH Command.
Use only with cyclic sleep modes active on remote modules.
FL (Software Flow Control)
Command
<Serial Interfacing> FL
Command is used to configure
of module with software flow
control. Hardware flow control
is implemented with the Zlinx
Module as the DO2 pin ( ),
which regulates when serial
data can be transferred to the
module. FL Command is used to
allow software flow control. XON
character used is 0x11 (17
decimal). XOFF character used
is 0x13 (19 decimal).
FT (Flow Control Threshold)
Command
<Serial Interfacing> Set/Read
the flow control threshold. When
FT bytes have accumulated in
the DI buffer, is de-asserted or
the XOFF software flow control
character is transmitted.
AT Command: ATFH
Binary Command: 0x0D (13 decimal)
