4 Manual Configuration [Advanced]
The Assisted Configuration described on the previous chapter is the
configuration method that fits most users’ needs. The Assisted Con-
figuration requires no deep understanding of the unit’s Event Machine
and Situation signals , it also eliminates the need of knowing TAIP
commands and understanding the communication mechanism of the
TAIP console. The
Manual Configuration described in this chapter
is usually chosen when the Assisted Configuration is not enough to
fit more complex users’ requirements. Manual Configuration can be
performed with the free software tool TAIP Downloader provided by
Digital Communications Technologies
TM
or it can also be performed
with any serial port terminal software like Windows Hyperterminal.

’s manual configuration is done through the unit’s TAIP
console via TAIP commands. The TAIP console can be used with
several communication methods:
•
The unit’s mini-USB port.
•
TCP or UDP (GPRS level) communication.
•
2-way SMS (GSM level).
This means that the unit is configured over-the-air in the
same way as it is done locally.
As described in the Operation chapter the TAIP console works on
a question-answer basis. So when configuring the unit, a similar
configuration-confirmation schema has to be followed. This means
that a configuration message which is in fact a TAIP set message
1
has
to be responded by the unit with exactly the same response message
2
before it can be assumed that the unit accepted the configuration
message. If this confirmation fails a retry-timeout mechanism has to
be followed.
All of the configuration messages are immediately saved on persis-
tent memory (they will not be lost when the power is lost) and with
a few exceptions described on the TAIP reference all commands take
effect immediately.
1
A TAIP set message is characterized by the letter
S
on the message’s qualifier.
Refer to the Operation chapter for more information.
2
A TAIP response message is characterized by the letter
R
on the message’s
qualifier. Refer to the Operation chapter.
