Remote communications 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 “op”, followed by the command name as shown in the Command Guide section
below. Depending on the command, these may be followed by operator and value. Each command line ends with an ASCII Carriage
Return character
(code 13):
op command operator <value>
•
The
<command>
string determines which setting the command will affect.
•
Spaces are required before the command, operator and value.
•
The
<operator>
string can take one of the following formats:
Operator type
<operator>
Description
Set
= <value>
Makes the setting take the
<value>
.
Get
?
Asks what the current value is.
The value is returned as an ASCII text string.
Increment
+
Increments the value.
Decrement
-
Decrements the value.
Execute
Performs an action. No operator is entered for this type of command.
Examples
op aspect = 1
sets the aspect ratio to TheaterScope
op aspect ?
asks what is the current aspect ratio
op resync
commands the projector to resynchronize with the current input signal
op aspect=1
is an invalid instruction because of the missing spaces before the operator and the value
op
zooms in the image
Notes
To set the default value of a
command, simply enter the
command name and
, without an
operator. For example
op aspect.ratio
will set
the aspect ratio to 0 (Source).
The projector response begins with
“ACK:” , to show your input has
been acknowledged.
For example, if you send
op aspect.ratio = 1
,
the projector will return
ACK:aspect.ratio = 1
and will change the aspect ratio
accordingly.
If your command has been rejected,
due to a syntax error or another
problem, the projector response will
be “ERR:” and a brief description of
the problem:
•
ERR:Invalid Command
- the
command is not recognized
•
ERR:NA
- the command is valid
but the projector is not in the
right mode to respond
•
ERR:Command Execution
Fail
- the command is valid but
the projector is not in the right
mode to respond
•
ERR:Invalid Command
Header
- the command header
is incorrect
•
ERR:Invalid Command
Operating Type
- the
operator does not match the
command
