How to work with External Modem

Connection/Disconnection

After an external modem has been connected to a BMXNOR0200H module, use the website to configure the module.

The main feature of the modem is the possibility to work in Permanent mode or in On-Demand mode:

Permanent mode: the connection is automatically performed when the BMXNOR0200H module is on power.
On-Demand mode: the connection or disconnection is performed depending on the command register.

Use the website to set a serial PPP connection.

NOTE: Do not forget to configure the serial port via the Website when the external modem is connected to it.

NOTE: GPRS MODEM does not support server mode.

Dialing

In practice, the Dial-in/Dial-out depends of the module mode. There are two different cases:

The module is in Server/Slave mode: the modem connected to the module is in Dial-in mode.
The module is in Client/Master mode: the modem connected to the module is in Dial-out mode.
