Digital Projection

Protocol commands

Commands are used to simulate menu operations and determine the settings of the projector, and use the following format:
•
All commands consist of ASCII text strings starting with an asterisk and ending with an ASCII Carriage Return character
*command operator <value>
•
<command>
The string determines which setting the command will affect.
•
Spaces are required before the operator and before the value.
•
<operator>
The string can take one of the following formats:
Command type <operator>
= <value>
Set
?
Get
Execute

Examples

*orientation = 3
sets the orientation to Rear Ceiling (for a celing mounted projector positioned behind the screen)
*orientation ?
asks what the current orientation is
*zoom.in
commands the projector to zoom in
*orientation=3
is an invalid instruction because of the missing spaces before the operator and the value

Responses

If the command has been successful, the projector response begins with
*orientation = 1
, the projector will return
model. In either case the projector will then will change the orientation accordingly.
If the command has not been acknowledged, due to a syntax error or another problem, the projector response will be
by a brief description of the problem.
