GSM network search and trouble shooting

The radio modem can be set up without CAN bus, controller or communication
to other software.
As soon as voltage is supplied to the unit it starts searching a GSM network inde-
pendently. The radio modem CR3103 should find a network after 30 seconds at
the latest, the CR3104 after approx. 60 seconds.
If the network search was successful the GSM LED is constantly lit green.
If this is not the case there may be the following error causes:
Error cause
SIM card
(see page 49)
GSM aerial
(see page 48)
CAN master
GSM network
RS232-Kabel
Avoid change of position in the online mode!
The passing on of a network connection from one radio cell to the next ("Hand-
over") during a direct modem connection may lead to faulty transmissions. Thus
it is possible in some cases that the handover cannot be carried out correctly and
the connection is interrupted.
This may e.g. be connected to the fact that no capacities are available on the
"new" transmitter or that the handover is not carried out fast enough and the
contact the "old" transmitter is interrupted.
Therefore a change of position during a direct modem connection should be
avoided.

Possible cause
• not inserted
• jammed
• contacts soiled
• does not support the available GSM network
• PIN no. configured incorrectly (see CANcom Configurator)
• not connected
• aerial connector only tightened loosely
• field intensity too low
• always resets the radio modem
(as a test operate CANcom without CAN master)
• no network available
• CANcom is connected to the PC via the serial interface
and changes into the configuration mode
