Records settings
Here user can modify if FM3622 device will send newest records first, meaning, that the
most important thing is to know recent position of car, older records are being sent right after
newest records arrive to AVL application.
Activate Data Link Timeout is used to set timeout of link between FM3622 and AVL
application termination. If FM3622 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.

GSM settings, GPRS part
‘GPRS’ defines main parameters for FM3622: 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.
Yet user can choose if device will work only in GSM network, or it will prefer 3G network
and switch to GSM only then 3G is absent.
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.
