Define a Non-Standard Device

To define a non-standard device in the Device Catalog module, you must give all required specifications for the selected device type. Some optional specifications can become required, depending on the values of required specifications. You can get these specifications from existing standard or non-standard devices, or you can enter them manually. See Device Catalog for more information on how to create and manage new devices.

The information on this page that follows is a complete list of the specifications that you must enter when you define a non-standard device. The specifications are separated by the type of device being defined.
