3-1. RS-232 Protocol Command
 Interface and Requirements
The RS-232 Commands use only ASCII characters which can be entered using a typical
terminal emulator like Windows HyperTerminal with the following setting:
Bits per second:
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Note that each input character will be echoed on the terminal by MCU and there is no need
to set the local echo "ON" with the terminal setting.

System Operation commands

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 functions 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.
Please refer to the following table for command list and examples:
