CMG-DCM

4 Configuration options

All DCM modules feature an on-board Web server, which you can use to set up the unit.When you first connect to the module, you will be shown a menu tree in a panel on the left, with a summary of its current status (see Section 5.7, “Summary”) on the right.

Links in the section of the menu tree marked Configuration allow you to change the settings used by the DCM itself. Once you have changed settings on any page, you should click Save changes at the bottom of the page for the DCM to make your new choices active. If you move to a different page without saving the settings, your changes will be lost.

To change the configuration of the digitizer(s) and instrument(s) attached to the DCM, you should use the Actions → Digitizer Setup page (see Chapter 5, “Actions”.)

Note: The DCM is a highly flexible unit, which can be supplied with a range of feature sets depending on your requirements. A stand-alone DCM unit normally has most of these options available to the user. However, some of the settings described below may not be relevant to your installation, and thus will not be available.

Conversely, a DCM may be supplied which supports multiple instances of a particular service (e.g. several CD1.1 transmitters.) In this case, each instance will have its own configuration page, which will appear as described below for that service. Users of installations which include several types of DCM or AM (Authentication Module) will find that each unit offers a different range of configuration options, according to its specialization as a component in the system.

In this chapter, the name of each setting is marked in italics. This name is

shown on the Web page interface, and can also be used to access the setting using the gcfgdbset command (see Section 6.2, “Command line tools”.)

4.1 General

This page contains a single setting.

general.hostname : This is the host name the DCM will use to identify itself. It is normally the first part of the module's fully-qualified domain name, for example, a DCM at myinst.bignet.org would have its host name set to myinst.
