product. Use ATHP to change channels in the MURS
version.
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

ATHP
Channel Number
– Select separate channels to minimize
interference between multiple sets of modules operating in
the same vicinity.
Range: 1 - 6

ATHS
Show History
– Show a table of listing the most recent
receptions, and the IDs that the data was sent from
No parameter

ATIC
Read Current Draw
Read the current draw in mA.
Accuracy is within 20% of actual current draw.
Range: 0-9999

ATL
Enable/Disable the LEDs
– 1 = LEDs always off. This
reduces some power consumption. 0 = LED operate
normally.

ATMK
Address Mask
– Configures local and global receive
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 F000. Set to 0000 to ensure the unit receives
data from ALL other radios, regardless of the TOID in the
transmission.
Range: 0000 - 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.

ATPE
Packet Error Display
–
Shows statistics to compute
packet-error rate. Displays Packets Per Minute (PPM) and
a running total.
None (display PER)
1 = reset counters
2 = Stop PER display

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. For the
MURS version, the ATPO setting is limited to 40%.

Symbol Peak Deviation
– Set the peak FM deviation of
the transmit symbols. Note: This can be a negative number
to invert the modulation.

ATR2
Over-The-Air bit rate
- This is the data rate the radio
uses to send data over the air.
All RF modems in the
network must use the same over-the-air baud rate
.
Refer to section 0 for information on how to set the OTA
baud rate.
