In case the software does not detect any modem the message MODEM
NOT FELT will be displayed.
If the software 8061SW-02 does not detect any modem or you are not sure
about the connection with the PC or its working conditions, proceed as
follows:
To use the "Modem, Point to Point" communication, the baud rate of
the Modem must be set to 115200.
When using a GSM Modem, make sure the PIN code of the SIM card in
use has been removed.
Preferably, a GSM PC modem should be used for calling remote
stations in "Modem, Point to Point" mode. A line modem can be used
but it should be connected to a direct phone line (the same connection
used for a fax machine). Sometimes, if there is a switchboard system,
it may only be possible to place outgoing calls but not to receive
incoming calls (where an extension may be needed, etc.).
- Remove the PIN CODE on the SIM card and be sure that on the
monitoring site the signal of the selected GSM provider is strong enough to
allow operations.
- Be sure that the tray for the SIM card is locked inside its slot
- Make sure all cables are well connected to the Modem.
- Make sure the serial port corresponds to the one selected.
- Send some commands by means of any Terminal program or similar
applications, to make sure the modem is working properly.
Every time the Area monitor is switched OFF, and the battery pack
disconnected from it, the internal clock has to be set. It is always
better prepare the first installation on site with the help of a laptop or
a tablet to verify that internal clock has the right hour and date
