Each bit that is a ‘1’ identifies an associated alarm condition that can
trigger the alarm output status line. Each bit that is a ‘0’ treats the asso-
ciated alarm as irrelevant when deciding whether or not to assert the
alarm output status line. For more information on tailoring the alarm
response, contact the MDS Technical Services Department.
ASENSE [HI/LO]
The
ASENSE
command sets or displays the sense of the alarm output at
Pin 25 of the
DATA INTERFACE
connector.
Entering the
ASENSE
command alone shows whether the alarm output is
active high or low. Entering the
ASENSE
command followed by
HI
or
LO
resets the alarm output to active high or low.
BAUD [xxxxx abc]
This command sets (or displays) the communication attributes for the
DATA INTERFACE
port. It has no effect on the RJ-11
DIAG.
port.
The first parameter (
xxxxx
) is baud rate. Baud rate is specified in
bits-per-second (bps) and must be one of the following speeds: 110, 300,
1200, 2400, 4800, 9600, 19200, or 38400.
The second parameter of the
BAUD
command (
abc
) is a three-character
block indicating how the data is encoded:
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 4800 baud, 8 data bits, no parity, 1 stop bit
(Example:
4800 8N1
).
NOTE:
7N1, 8O2, and 8E2 are invalid communication settings and are
not supported by the transceiver.
BUFF [ON, OFF]
This command sets or displays the received data handling mode of the
radio. The command parameter is either
ON
or
OFF
. The default is
ON
.
The setting of this parameter affects the timing of how received RF data
is sent out the
INTERFACE
connector. Outgoing (transmitted) data is not
affected by this setting.
If data buffering is
OFF
, the radio operates with the lowest possible
average latency. Data bytes are thus sent out the
INTERFACE
port as soon
as an incoming RF data frame is disassembled. Average and typical
latency will both be below 10 ms, but idle character gaps may be intro-
duced into the outgoing data flow.
