Editing Image knob list
If your test environment requires only a subset of the available built-in images, you can
configure the 802 to show only the images you want, in the order you want, when the
Image knob is turned. The 802 maintains a list of these images in non-volatile memory.
You can edit this list to include images you have created and to remove unneeded images.
The Image knob list can be edited using the command line interface; however, the most
convenient way to edit the knob list and create custom knob lists is using VGM. Please
refer to the VGM online help for procedures on editing image knob lists.
The default Image knob list is named img. In addition to editing this list, you can also
create new lists and name them to reflect their uses at your site.
Editing image knob list using internal editor
Use the following procedures to edit the image knob list using the internal image editor.
To edit list of images:
1. Power-up the generator while holding down the Image key until programmer is
displayed.
2. Select the ImgList image.
3. Press the Step key to start the image list editor.
The left side of the screen shows the current contents of the image list. The images are
listed in the order that they are selected by the Image knob during normal operation.
The right side of the screen shows all of the available images. The built-in images are
at the top of the list, followed by a factory default custom image. This image is used as
starting point to creating you own custom images. Any user-defined images in
non-volatile memory are at the bottom of the list.
4. Use the Format and Image knobs to select images in the lists. Use these commands
to edit the image list.
Key Function
Insert (DCS) Inserts the image selected in the list of available files before the image
selected in the image list.
The current firmware does not allow entering a secondary version of a
built-in image to the list. The primary version will need to be first
selected during normal operation. Pressing the Image key will then
select the secondary version.
Delete (B) Remove the selected image from the image list.
