The links in the menu on the left lead to various pages where you can change the configuration of the DCM. Initially, you should be sure to change your administrator password. Click on Administrators under Network configuration, fill in the new password in the two text boxes below Existing accounts, near the bottom of the page, and click Change password. If you want to add any other named accounts, you may do so at this stage (see “Administrators” in Section 4.4)..

At this point, you should configure the DCM for your own needs. Examples of how to configure a DCM for several common applications are given in Chapter 3, “Usage”, whilst a full reference is provided in Chapter 4, “Configuration options”. Some important points to note are:

The DCM uses internal serial and Ethernet ports to communicate with the digitizer and the network. Altering the settings under Serial port configuration or Network configuration may make the DCM unreachable over the network. You should review carefully any changes you make to these settings before committing them.

You can disable the DCM's ssh, http, and https servers using the links under Data transfer. Before doing this, you should ensure that you will still have access to the DCM by other means, e.g. by logging in directly over ssh.

Setting up digitizers

You can change the configuration of attached DM24 digitizers through the DCM's web page interface. To do this, click on Digitizer Setup beneath Actions in the menu tree. The DCM will then retrieve the current configuration from the DM24, which will take a few seconds. This done, a page will appear allowing you to alter the digitizer's settings:
