2. Have the unit exchange any binary messages with accessories
like MDTs or PDA-like devices that can communicate over RS-
232. In this mode any binary data except an user-defined escape
value may be used.
The unit’s default setting is to work as described on the first option.
That is it, the serial port is ready to exchange TAIP messages with
the unit’s TAIP console unless the user switches to the second mode.
In the second mode the unit will not listen to TAIP commands and
the only procedure that can get it back to the TAIP console is receiv-
ing a pre-configured escape character. This character defaults to the
hex value
1B
or the “ESC” key on a terminal software. The
MT
TAIP
messages controls the serial’s port mode, see the TAIP reference and
the
Configuration chapter for more information.
The serial port works at 9600bps with 8 data bits, no parity and
one stop bit (9600,8N1). It does not use any flow control method
and all of the RS-232 communication lines on the DB9 connector are
used. The
Antares SB
TM
works as a
DCE
device, meaning that it is
connected to a PC with a one-one cable.
The serial port works with pure RS-232 hardware as well as with
USB to RS-232 converters.
When using the unit’s serial port for the first time, the >
QVR
<
TAIP command can be used to test the communication path. The
unit should respond with its firmware version on a message like
this: >
RVR; Antares GSM 05.21;ID=0000
< .
Note:
Once you are able to communicate you can start interacting with
the unit’s TAIP console, refer to the
TAIP console section on this
chapter for more information.
