3.4 The DCM as a network data hub

The most flexible way to operate the DCM is as a fully independent machine on your local area network. To do this:

1.Connect Gü ralp digitizers to PORT A and PORT B as necessary, using the serial data cable provided.

2.If you are using the DCM's USB capabilities, connect your external hardware or computer to the USB socket.

Note: USB distinguishes between hosts and clients. The DCM can act as either, depending on the options you specified at manufacture. If your DCM is a host, you can attach external USB peripherals such as hard disks. If it is a client, you can attach it to a computer, and it will appear as a network interface.

3.Connect a Gü ralp combined serial/power cable to the DATA OUT port. Make up a connector if necessary, and attach the power lines to a 12 V DC power supply.

4.Connect the 9-pin serial socket to a computer for configuration.

5.Connect an Ethernet cable to the NETWORK socket, and set up the network as described in Section 2.4, “Connecting to a local network”.

You should now be able to connect to the DCM's Web setup interface by typing its IP address into any browser, e.g.

https://192.168.0.2/
