FR
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.
FX
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
GP
Group Number
– Set/read the group number for this unit.
0 means ignore the group number. 1-255 is a group identifier.
Only M8s with the same Group Number will communicate
together.
0-255
0 (ignore
group
numbers)
HP
Channel Number
– Select separate channels to minimize
interference between multiple sets of modules operating in the
same vicinity. The channel number is stored in EEPROM
memory.
Range: 1
– 6

HS
Show History
– Show a table of listing the most recent
receptions, and the IDs that the data was sent from
No parameter
HX
Enable/Disable single-hop repeating
–
0=any number of
repeats, 1
– unit will not repeat a packet that was already
repeated.

IO
Configure the I/O
The proper hardware option must be
installed in the modem. All
M8
modems support RS-232
mode.

IC
Read Current Draw
Read the current draw in mA. Accuracy
is within 20% of actual current draw.
Range: 0-9999
N/A
JF
Read/set the CTS threshold
– Set the serial buffer threshold
where the CTS line is negated. By default the ATJF level is at
80% of the internal buffer size.

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

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

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

NB
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

PE
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
None
PO
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.
