DT (Destination Address) Command
<Networking> DT Command is used to set/read
the networking address of an XStream Radio
Modem. XStream Radio Modems uses three
network layers –Vendor Identification Number
(ATID), Channels (ATHP), and Destination
Addresses (ATDT). DT Command assigns an
address to a radio modem that enables it to
communicate only with other radio modems
having the same addresses. All modules that
share the same Destination Address can
communicate freely with each other. Radio 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.
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)
E0 (Echo Off) Command
<AT Command Mode Options> E0 Command
turns off character echo in AT Command Mode.
By default, echo is off.
AT Command: ATE0
Binary Command: 0x0A (10 decimal)
E1 (Echo On) Command
<AT 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.
AT Command: ATE1
Binary Command: 0x0B (11 decimal)
ER (Receive Error Count) Command
<Diagnostic> Set/Read the receive-error. 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
radio modem’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 radio modem is reset.
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)
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
transmit. WR (Write) Command does not need to
be issued with FH Command.
AT Command: ATFH
Binary Command: 0x0D (13 decimal)
Use only with cyclic sleep modes active on remote modules.
FL (Software Flow Control) Command
AT Command: ATFL
Binary Command: 0x07 (7 decimal)
Parameter Range: 0 – 1
Parameter
Configuration
0
<Serial Interfacing> FL Command is used to
configure software flow control. Hardware flow
control is implemented with the XStream Module
as the DO2 pin (pin 1,
), which regulates
when serial data can be transferred to the
module. FL Command can be used to allow
software flow control to also be enabled. XON
character used is 0x11 (17 decimal). XOFF
character used is 0x13 (19 decimal).
