Activate Data Link Timeout is used to set timeout of link between FM1000 and AVL
application termination. If FM1000 has already sent all records it waits for new records before
closing link. If new records are generated in the period of this timeout, and minimum count to
send is reached, they are sent to AVL application. This option is useful when GSM operator
charge for link activation.
Server Response Timeout is used to set time period waiting for response from server side.

GPRS
‘GPRS’
defines main parameters for FM1000: GSM operator APN and GPRS username and
password (optional
–
depending on operator), destination server IP and port, and allows to set
protocol used for data transfers
–
TCP or UDP. FM1000 additionally supports backup server. If
main server is not responding, FM1000 connects to backup server and still sends records for 5
min (MAX) or until link is not closed (can be closed by configurable Active link TMO
parameter). Both servers have the same configurable parameters.
Some operators use specific authentication for GPRS session
–
CHAP or PAP. If any of these
is used, APN should be entered as ‘
chap:
<APN>
’ or ‘
pap:
<APN>
’. I.e. if operator is using APN
‘internet’
with CHAP authentication
, it should be entered as ‘
chap:
internet
’.
Information
about APN and authentication type should be provided by your GSM operator.
