DT (Destination Address) Command
<Networking and 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 Destination Address (ATDT). The DT
command assigns an address to a module that enables it to communicate 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 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), MY (Source Address)
E0 (Echo Off) Command
<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
<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.
AT Command: ATE1
Binary Command: 0x0B (11 decimal)
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 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.
