4.3. *DESTINATIONS (DPS AND DAS)
4.3.1
Destination Points (DPs)
As mentioned above there are 16 DPs, these are divided in the fol-
lowing way:
•
The first 10 (DPs 00 to 09) are IP hosts. These are defined
with an IP address or a server name and a TCP or UDP port
number.
e-track
TM
’s
is a TCP and/or UDP
client which always
starts the communication. This means that the IP host (Trackin
Server) has to be a TCP or UDP server listening for incoming
connections on the same port specified on the DP field.
•
The next 5 (DPs 10 to 14) make reference to mobile phone
numbers. These numbers are used by
e-track
TM
to send SMSs or
make voice calls. They are also used as authorization numbers
for receiving TAIP commands via SMSs only from the numbers
listed as DPs. Also, incoming voice calls are only answered
when the remote party is any of these numbers.
•
The last DP (15) makes reference to the USB communication
port.
For more information see the
XADP
message.
4.3.2
Destination Addresses (DAs)
A
Destination Address
is a user-defined group of
Destination Points
.
This enables some reporting commands to route their report to sev-
eral destinations at the same time with a single definition. Up to
10 (0 to 9) DAs may be defined. Refer to the
DA
message for more
information. This command enables the user to group a list of DPs
and/or a range of DPs.
The main use for DAs is on the
routing options
of an event defi-
nition. The
Event Machine
section gives more information about
this. What should be clear on this, is that
a report generated by an
event is always sent to a DA, not to a single DP
. For this reason DAs
make part of the minimum configuration required by the unit. Some
examples of DAs’ definitions are:
1. Defining DA 5 as the group containing DPs 04, 06, 10 and 15:
>
SDA5;P04,P06,P10,P15
<
This will make any event using DA 5 as
Destination Address
on its routing options to send the same report to the IP host
04, IP host 06, phone number 10 and the unit’s serial port. Such
5
The unit can also be set to listen for UDP queries, working as an UDP-server.

XAUP
