MDS 05-2708A01, Rev. A MDS TransNET I/O Guide 27
NOTE: It is recommended that the last four digits of the master radio’s serial
number be used for the network address (or chassis serial number if
the radio is installed in a P-20 redundant chassis).
ALARM
Table and information pending.
AMASK [0000 0000–FFFF FFFF]
This command sets the alarm bits that cause the alarm output signal to be
triggered. The PWR LED will still flash for all alarms, but the alarm output
signal will only be activated for those alarms that have 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.
ASENSE [HI/LO]
This command is used to set or display the sense of the alarm output at Pin 25
of the DATA INTERFACE connector. The default for transceivers is active HI.
BAUD [xxxxx abc]
This command sets or displays the communication attributes for the DATA
INTERFACE 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: 1200, 2400, 4800,
9600, 19200, or 38400. In the worst case, the radio will always accept a
minimum of 500 data bytes in a single continuous data transmission. At baud
rates of 4800 bps or less, the radio can support unlimited continuous data
transmission at any hop rate. If hop time is set to
NORMAL or LONG, baud rates
of up to 19200 bps with continuous unlimited data transmission are possible.
(See HOPTIME command.)
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 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 received data sent out the DATA
INTERFACE connector. Data transmitted over the air by the radio is unaffected
by the BUFF setting.
