AT
Command
Command Description Parameters
Factory
Default
AK
Enable/Disable ARQ – When ARQ is enabled, this modem
will automatically send an ACK packet back to a modem that
sends it data. 0=off, 1=on.
Range: 0 – 1
0 (no AKCs
sent)
BD
Baud Rate – Sets serial COM port baud rate (bps). Over-the-
air (throughput) baud rate is set with ATR2 command.
If a PC’s serial baud rate is set higher than the fixed over-the-
air baud rate of the module, hardware handshaking may be
required.
Range: 0 – 7
0 = 1200 5= 38400
1 = 2400 6=57600
2 = 4800 7=115200
3 = 9600
4 = 19200
3
BC
Busy Channel Lock Out
–
Enable/disable the BCL. If
enabled, the modem will not transmit on a radio channel that
is busy (has RF on if). 0-OFF, 1=ON.
Range: 0-1
1
CH
Configure Hardware Flow Control
–
Enable (1) or disable
(0) flow control. When enabled, the modem will monitor the
RTS line, and if it is negated, stop sending data out the serial
port. If disabled, the modem will ignore the state of RTS, and
always send out charators.
1 = Enable
0 = Disable
0
CN
Exit AT Command Mode
–
Exits module from AT Command
Mode and returns it to Idle Mode. Parameters are not saved
in EEPROM.
none
none
CT
Command
Time Out
–
If no valid commands have been
received via the serial port within this time period (in
milliseconds), modem returns to normal operation mode from
Command mode. If the CONFIG button inside the M7 is
pressed, this parameter will be automatically set to 60000.
Range: 100-60000mS
60000
DT
Destination Address to call– Sets address of the modem to
send data to. Note, this parameter is entered in HEX format.
Each digit may be a 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or an F.
Range: 0-FFFF 1234
E
Echo – Character echo set on (E1) or off (E0). This applies to
the Command Mode only.
Range: 0 , 1 0 (no echo)
F
Display frequencies
–
Display all of the frequencies
programmed into all of the channel memories.
N/A
HP
Channel Number – Select separate channels to minimize
interference between multiple sets of modules operating in the
same vicinity.
Range: 1 - 6
1
IC
Read Current Draw Read the current draw in mA. Accuracy
is within 20% of actual current draw.
Range: 0-9999 N/A
L
Enable/Disable the LEDs – 1 = LEDs always off. This
reduces some power consumption. 0 = LED operate normally.
0 or 1
0
MK
Address Mask
– Configures local and global address space.
Each digit may be a 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or F. In
most applications, this is kept at FFFF.
Range: 0000 - FFFF
FFFF
MY
Unit Address
– Configures the individual; address for this unit.
Each digit may be a 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,or F. Note:
FF is interpreted as a group. See addressing section.
Range: 0000 - FFFF
