Appendix
Canon LX-MU700 Protocol Command
The commands are available when Standby Mode is Standard.
Interface and Requirements (Ver 0.3)
Serial (RS-232) Interface
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: 115200 (default) / 57600 / 38400 / 19200 / 14400 / 9600 / 4800 / 2400 (selectable
by OSD)
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.
TCP/IP Interface
The operation commands are available through telnet protocol. See page
Serial and TCP/IP Interface over HDBaseT
Serial bits per second setting is fixed to 9600 over HDBaseT. The other settings are same as above.
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:

Motor Operation Command
For motor control like lens shift, focus and zoom, the parameters " + " and " - " are defined as follows.
