1.3 System Operation commands
Introduction
The Operation commands tell the projector what to do. All commands start with 2 letters: “op” for operations
commands and a space [SP] then following a control command then finally the value wants to read, set, increase or
decrease. All commands must end with a carriage return (ASCII hex 0D), shown as [CR] below. The syntax for
operations commands is as follows:
op[SP]<operation command>[SP]<Setting Value>[CR]
For all but Execute functio
ns the response from the projector will be the command and “= <value>” where <value> is
the current value or “NA” if the value is not available. For Execute functions the response will be the same command.
All responses will be in CAPS and also ending with a carriage return (ASCII hex 0D). Please refer to the following table
for command list and examples:
System Operation Commands:

Set = <value> Makes the unit take that value.
