To change and save the configuration for an existing device:

1. Click on Configuration.
2. Scroll down to the Device Configuration section of the page, and click on the Name of an existing Projector or Screen.
3. Fill out the Configuration form with information about your device.
4. Click on Save.
   Various integrity checks will be performed. If there is an error, appropriate messages will appear near the errant fields and the user must correct them before the configuration can be saved.
5. Go to the Windows Start Menu, and select All Programs/Spinoza Technology/Restart Navigator Services.

NOTE: There are two Device Configuration pages, one each for projectors and screens. The projector page is described here; the screen page is virtually identical (with some controls removed). The Device Configuration pages have 2 modes: Edit or New. The page is identical, except for some control labels (Save Changes vs. Add Projector). Also, since the device has yet to be added, no Events will appear in New mode.

The following describes each of the fields on this page:

• Name – the user can supply any unique name for a projector. This is the name that will appear on all displays for that projector.
• Driver – this read-only field describes the current driver for that projector
• Port Family – this read-only field describes the port being used to communicate with the device
• Max Lamp Hours – this read-only field is based on the driver and defines the anticipated lifetime of the projector lamp.
• Custom Page URL – this optional field can be used to define the address of the device’s internal web page, if any. Some devices support direct control via an internal web page. If this field is provided, it will appear as a link on the site configuration page.
• Device Access – describes how the projector is connected. Serial (or COM) ports are described by numbers; they must be hard-wired via cable from the Device Server computer to the projector. More often, a network configuration is used. The appropriate choice is selected from the dropdown, which will initialize the address and port fields. The user then adjusts the address field as appropriate to the device. Typically, the default port value is correct and need not be modified.
• Manufacturer – selection of the manufacturer from this dropdown will control which choices are available under the Model dropdown.
• Model – combined with the Manufacturer, this defines which driver will be used to communicate with the projector.
• Locations – all defined Locations appear here in a list. The user can add or remove a projector from a Location via the check boxes.
• Scheduled Commands – Scheduled Command editing is an Advanced feature (described in that section). On this page, it operates just like the device and Location lists on the Site Configuration page. Click the name to get to the command, check the box to delete it, and use the Add button to define a new event. Because Scheduled Commands are what keep the system aware of the status of devices, caution must be taken when modifying them.
