The following commands are implemented by the Atlas SM.
Command
Command Description
Parameters
Factory
Default
ATBD
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
5
ATDT
Destination Address– Sets address of the modem to send
data to.
Range: 0-9999
0001
ATF
Display frequencies – Display all of the frequencies
programmed into all of the channel memories.
N/A
ATFT
Transmit Frequency – Program the transmit frequency for
this channel. Enter in Hz or in MHz. The frequency will
automatically be saved in non-volatile memory (flash) for this
current channel number.
Range: See product data
sheet. For MURS products,
frequency cannot be changed.
See
product
data sheet.
ATFR
Receive Frequency – Program the receive frequency for this
channel. Enter in Hz or MHz. The frequency will
automatically be saved in non-volatile memory (flash) for this
current channel number.
Range: See product data
sheet. For MURS products,
frequency cannot be changed.
See
product
data sheet.
ATFX
TX and RX Frequency – Program the receive and transmit
frequency for this channel. Enter in Hz or MHz. Same as
issuing an ATFR and an ATFT command. The frequency will
automatically be saved in non-volatile memory (flash) for this
current channel number.
Range: See product data
sheet.
N/A
ATGP
Group Number – Set or read the unit’s Group Number. 0
means this feature is not used. If GP is set to any number
other than 0, then all radios communicating with this unit must
have the same group number programmed into them.
Range 0-255
0
ATHP
Channel Number – Select separate channels to minimize
interference between multiple sets of modules operating in the
same vicinity.
Range: 1 - 6
1
ATIC
Read Current Draw Read the current draw in mA. Accuracy
is within 20% of actual current draw.
Range: 0-9999
N/A
ATMK
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
ATMY
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
1234
ATNB
Parity – Selects parity format. Settings 0-4 transfer 8-bits over
antenna port and generate the parity bit on the RF receiving
side.
Range: 0 – 5
0 = none
1 = Odd
2 = Even
3 = Mark (1)
4 = Space (0)
0
ATNS
Stop Bits – Selects the number of stop bits.
Range: 1-2
1
ATPO
RF Power Output. Set or show the RF power output setting.
Value is in percent, from 0% to 100%. Use and RF wattmeter
to confirm the power setting, and adjust the % accordingly to
obtain the desired RF power level.
0-100
100
