ATBW
Set/Read IF Bandwidth - Sets the IF bandwidth to narrow (N)
or wide (W). Narrow is for 12.5kHz channels, and wide is for 25
or 30kHz spaced channels.

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.
0 or 1
0 (multi-hop
OK)

Listen Address
– Configures the listen address for this unit. The
unit will receive data if this listen address matches the destination
address in a data transmission. FFFF to disable it.
Range: 0000 - FFFF

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

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.
Not linear, it’s an adjustment in PO.
0-100

R0
Symbol Peak Deviation
– Set the peak FM deviation of the
transmit symbols. Note: This can be a negative number to invert
the modulation.
Range: -1000 – 1000
120**
AT
R2
Over-The-Air bit rate - 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 the section “
” for information on how to set the OTA baud rate.
Range: 0 - 12
0 = 800
5 = 9600 2L
1 = 1200
6 = 19200 4L
2 = 2400
7 = 5142 2L
3 = 4800
8 = 9600 4L
4 = 8000 4L

AT
R5
Preamble length – The number of bytes to send over-the-air in
the pre-amble.
Range: 3 - 255
5

(Varies based on
data rate and
radio type. 7
typical)
AT
RB
Number of retries. If this modem does not get an ACK back
when it sends data, this is the number of times it will re-transmit
the packet and wait for an ACK. 0=disabled feature.
Range: 0-99
0
(ACKs are not
used)
AT
RF
RF Carrier Required – When enabled, there must be RF
energy on the channel for the modem to output data.
Streaming data mode only. 1-RF required. 0=ignore RF energy
when receiving.
Range: 0, 1
0 (no RF
required)
AT
RV
Disable Remote Access – When enabled (set to a 0), the
modem will respond to over-the-air RPR requests, Pings, and
over-the-air commands. Default is OFF (1).
0 = Remote Access on
1 = Remote Access off

TT
Max Packet Size
–
Set the maximum number of bytes in an
over-the-air packet.
1 - 512

Xn
Show or Configure the Repeat Table
– Set the addresses that
this unit will store-and-forward data to/from. n = 1, 2, 3, or 4
designating the entry in the table to show or edit..
Four parameters
aaaa bbbb cccc dddd where
aaaa=Source Address
bbbb = S.A. Mask
cccc = Destination Address
dddd = D.A. Mask

XR
Enable/Disable Store and Forward Repeating
–
0=disabled, 1
– enabled.
0 or 1
0 (Off)
AT
XT
Read/set repeater delay
–
Read or set the repeater delay. This
is the time between receiving a data packet, and the time the
repeater will re-send it.
PRDT

pattern. Returns 0 if it does not.
