Notes on error codes:
1.
GPS timeout
No GPS fix has been returned for the specified timeout period (GPST). Could be an indication
of an antenna fault or simply that the vehicle is parked in covered area (e.g. underground car
park).
2.
Modem GPRS attach fail
Can be simply due to GSM network coverage, but persistent attach failure is an indication that
the GSM SIM card is not enabled for GPRS.
3.
Modem GPRS connect fail
If the modem is attached, but not connected, this is usually caused by incorrect GPRS access
point settings (APAD, APUN and APPW). See appendix E for a list of access point details for
most networks.
4.
Modem TCP socket error
The modem has failed to open a socket on the specified IP address and port number. Can be
caused by incorrect TCP address settings (IPAD, PORT), a fault at the host server or even wider
internet problems.
5.
Modem TCP acknowledgment fail
This error code indicates that the AT100 can proceed all the way to open a socket and deliver
the report packet, but does not get the normal acknowledgment response from the host TCP
application. This is normally caused by a fault at the host end.
6.
Ignition input inactivity error
This error is set when no ignition events have been detected for more than 24 hours
