Wolf Cinema Owner's Manual
B-45
When a request is made to retrieve the user message that has already been set, the returned
value is displayed in the same format as setting the text.
examples:
(usr“hello world”) - basic user message.
(usr“hello world\nline two”) - message with new line in the middle.
(usr“Contact \“freddy\” for help”) - message with embedded quote.
See 2.1, Basic message Structure for text parameters.
Vbl Video black level
Use VBl to set black levels to 0 ire (0) or 1 (7.5 ire) for video signals. most nTSC standards
include a 7.5ire “Setup” to the video black level. By adjusting this setting the projector can be
optimized for incoming data with or without this “Setup”. if it is set wrong the image will have
elevated blacks or crushed blacks.
VRT Vertical Position
Use VrT to adjust the vertical position of the image.
VsT Vertical stretch
Use VST to electronically stretch the image vertically (200-4000) without affecting the horizontal
size. 1000 is the neutral position (no stretching).

P1 = index of the position to set or request
P2 = value to set if it is a set command
The valid indices are as follows, each with a range that depends on the resolution of the projector
you are working with:
1 = Top left Corner – Horizontal Position (x)
2 = Top left Corner – Vertical Position (y)
3 = Top right Corner – Horizontal Position (x)
4 = Top right Corner – Vertical Position (y)
5 = Bottom left Corner – Horizontal Position (x)
6 = Bottom left Corner – Vertical Position (y)
7 = Bottom right Corner – Horizontal Position (x)
8 = Bottom right Corner – Vertical Position (y)
