AT
R2
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
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

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
1
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
AT
TT
Max Packet Size
–
Set the maximum number of bytes in an
over-the-air packet.
1 - 512
80
TXHOLD
TX Hold ON
–
Will hold the transmitter on between transmissions
for x amount of milliseconds waiting for more data
0
AT
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
AT
XR
Enable/Disable Store and Forward Repeating
–
0=disabled, 1
– enabled.
0 or 1
0 (Off)
AT
XT
Read/set TX delay
–
Read or set the repeater/ACK delay in mS.
This is the time between receiving a data packet, and the time
the repeater will re-send it. If ACK feature is enabled, the delay in
the ACK will also use this value. Default is 0, no delay.
0
– 2000
milliseconds
0
(No Delay)
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
-
REPEAT
Turn Repeater feature on/off. If 1, a quick way to enable
repeating all packets. I f 0, disables the repeat feature.
0 (off) or 1 (on)
0
RPR
Remote Procedure Request.
Used to request execution of a
command on a remote mode (over the air). See
M8S System
Protocol
manual for information on using this feature.
** indicates values that are calibrated in the factory and are unit-specific.
5.3. 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.
