The Operation Commands
•
Operation commands are used to simulate menu operations and determine the settings of the projector, and consist of ascii text strings
starting with a prefix code, then the letters ‘op’, and ending with a carriage return character:
<prefix code> op <operation> <command> [CR]
•
The <operation> string depends on the operation, and these are listed on the following pages.
•
The <command> string can take one of the following formats:
<command>
Description
Set
= <value>
Makes the setting take that value.
Get
?
Asks what the current value is. The value is returned as an ascii text
string.
Get commands do not work when projectors are connected in a daisy
chain
Increment
+
Adds 1 to the current value.
Decrement
–
Subtracts 1 from the current value.
Execute
(none)
Performs an action.
Examples
<prefix code> op aspect = 1 [CR] sets the aspect ratio to 16:9
<prefix code> op aspect ? [CR]
asks what is the current aspect ratio
<prefix code> op brig [CR] increments the brightness setting
<prefix code> op contrast – [CR] decrements the contrast setting
<prefix code> op resync [CR]
commands the projector to attempt to re-synchronise to the current input source
Notes
Details of how to connect to
the projector, using the LAN or
RS232 input, can be found in the
Connections Guide
.
For information about the
prefix
code
, see earlier in this guide.
The prefix code should NOT be
used unless a number of projectors
are connected in a daisy chain.
Get ? commands do not work when
projectors are connected in a daisy
chain.
Note: spaces in the commands are
necessary.
eg
op aspect = 1
NOT opaspect=1
in hex:
6F 70 20 61 73 70 65 63 74 20 3D 20 31 0D
o p a s p e c t = 1
