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
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
None
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
ATR0
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**
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 Error!
Reference source not found. for information on how to set the
OTA baud rate.
Range:
0 = 800 5 = 9600 2L
1 = 1200 6 = 19200 4L
2 = 2400 7 = 5142 2L
3 = 4800 8 = 9600 4L
4 = 8000 4L 9 = 2000 2L
5
(600)
ATR5
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)
ATRB
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)
ATRF
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)
ATRV
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
1
ATTT
Max Packet Size – Set the maximum number of bytes in an
over-the-air packet.
1 - 512
80
ATXn
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
ATXR
Enable/Disable Store and Forward Repeating – 0=disabled, 1
– enabled.
0 or 1
0 (Off)
ATXT
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.
PING
Ping another modem. Format is PING xxxx, where xxxx is
the ID of the modem to ping. If remote access is enabled on
xxxx, it will respond.
XXXX
-
** indicates values that are calibrated in the factory and are unit-specific.
6.3. Paging Receiver Related Commands
The following commands are specific to the operation of the M8S in the paging
decoder mode. The ATMT and ATMA commands configure the M8S to operate
in the paging decoder mode.
