Troubleshooting
No connection with the modem
If there is no communication with the modem take the following steps:
• check all external connections with the modem (serial interfaces, USB, power
supply).
• check that the power supply is correct (see Power connector).
• check that the COM port is correct.
• check that the Teleorigin Manager program is working properly and that no other
program is interfering with it.
• when connecting the modem with the meter, check whether the meter is powered
and the POWER diode in the modem is on.
