7.Advanced usage: If you later want to connect your computer to a local area network, you can make the DCM visible to that network by setting up a network bridge. Before doing this, you must make sure that the IP addresses you have chosen for the DCM and your computer are suitable for the local network you want to connect it to.
To set up the bridge, open the Network Connections window, and select the connections corresponding to the DCM and your network. Click Bridge connections, and follow the instructions in the wizard.
If you are using Linux or another operating system, you should see its own documentation for more details.
Using an internal modem
If you have ordered a DCM with an internal PCMCIA modem, it will automatically listen for incoming PPP connections. This is most useful if the DCM is integrated into a borehole instrument, which can then be connected to a modem at a central data collection point. The modem within the DCM appears on the Web configuration interface as a serial port, allowing you to change the service it provides and the data transfer settings it uses. For example, if you do not want the internal modem to use PPP, you can configure it to use mgetty instead and log in directly.
Connecting over USB
If your DCM is equipped with the USB client interface, you can connect it directly to any computer with a USB socket. When this is done, the computer treats the module as if it were a standard network card. For example, to connect the DCM to a PC running Microsoft Windows, you should:
1.Link the DCM's USB port to any available USB socket on the computer.
2.After a short wait, Windows should report that a new USB device has been detected. When prompted to install drivers for it, you should use the ones provided on CD by Gür alp Systems.
Once the “network card” is installed, the two machines will consitute a network segment, and each will have its own IP address on that segment. See Section 2.4, “Connecting to a local network” for details on how to configure TCP/IP on the DCM. If you wish, you can set up a network bridge between this connection and a local area network or the Internet as described above.
