6.2 Common problems

Problem: The modem will not connect to the GSM network
Possible causes:
- PIN security is still on sim card. Check this by putting the sim card in a normal phone and turn it
on. When turning the phone on, it should not ask for a pin code, not even 0000. Solution: turn the
security off.
- No network reception, try moving the modem around or use a different antenna. Try powering
the modem at a location where you have full reception on a normal GSM phone. You can test this
without the Multi or BMV-602 connected.
- SIM slot on modem is not correctly closed: make sure that you close the black slide over the sim.
Problem: The modem will not connect to GPRS (SMS works correctly).
Possible causes:
- GPRS parameters are not configured (correctly). Solution: configure the modem by using the
'gprs' sms command. See paragraph 4.2.
- GPRS functionality is not enabled on the sim card. First, try using GPRS on a normal cell phone
with this sim card. Most networks will be able to auto configure your phone. If GPRS works on the
phone it should also work on the modem (when using the correct settings). If GPRS does not
work: please contact your network operator to enable GPRS communication.
Problem: I get a sms saying "Warning MK2 version [version number] not supported".
Cause: The minimal MK2 version required is 1130125. Please use the MK2 that was supplied to
with unit or connect it to the latest version of VEConfigure.
Problem: I get a sms saying "Warning target version [version number] not supported".
Cause: The minimal version of the VE.Bus device connected has to be 19xx111
Problem: The VE.Bus device (Multi/Inverter/Quattro) switches off when I connect it to the MK2.
Cause: The MK2 needs to have the two jumpers removed. Please note: these jumpers are
already removed on the MK2 supplied with the Victron Global Remote.
