AMASK [0000 0000–FFFF FFFF]
Alarm Mask
This command sets the alarm bits that cause the alarm output signal to be trig-
gered. The
PWR
LED still flashes for all alarms, but the alarm output signal
is only activated for those alarms having the corresponding mask bit set. The
hex value for the mask aligns directly with the hex value for the
ALARM
command. The default is
FFFF FFFF
. Through proper use of the
AMASK
command, it is possible to tailor the alarm response of the radio. Contact the
factory for more information on configuring the alarm mask.
AT [ON, OFF]
Hayes-Compatible AT Command Support
AT-style modem commands, also know as “Hayes-Compatible Commands”,
can be processed through the payload port. By setting
AT ON
at the Master
(
MODE M)
, individual Remotes can be accessed by using
ATDT
[Unit Address]. In this mode, RTUs designed only for dial-up access can be
accessed through the Master station. For more details, see See
and
.
ASENSE [HI/LO]
Alarm Output Sense
This command is used to set the sense of the alarm output at Pin 3 of the OEM
module’s
INTERFACE
connector, J3, and Pin 6 of the Evaluation’ PCB’s
DATA
connector. The default is
HI
which means an alarm is present when an
RS-232 high is on Pin 6.
BAUD [xxxxx abc]
Data Interface Port Baud Rate
This command sets or displays the communication attributes for the normal
payload communications through the
DATA
port. The command has no effect
on the RJ-11
DIAG(NOSTICS)
port.
The first parameter (
xxxxx
) is baud rate. Baud rate is specified in
bits-per-second and must be one of the following speeds: 300, 600, 1200,
1800, 2400, 4800, 9600, 19200, 38400, 57600, or 115200. At baud rates of
19200 bps or less, the radio supports unlimited continuous data transmission
at any hop rate.
The second parameter of the
BAUD
command (
abc
) is a 3-character block
indicating how the data is encoded. The following is a breakdown of each
character’s meaning:
a
= Data bits (
7
or
8
)
b
= Parity (
N
for None,
O
for Odd,
E
for Even)
c
= Stop bits (
1
or
2
)
The factory default setting is 9600 baud, 8 data bits, no parity, 1 stop bit
(Example:
9600 8N1
).
NOTE:
7N1, 8O2, and 8E2 are invalid communication settings and are not supported by the
transceiver.
