2. Choose Serial and the corresponding COM port as the communication port. In this given example,
COM6 is selected.
3. Finish Serial port setup.
Baud rate 9600 / 14400 / 19200 / 38400 / 57600 / 115200* bps
Check the baud rate of the connected projector from its OSD menu.
*Default baud rate
Data length 8 bit
Parity check None
Stop bit 1 bit
Flow control None

RS232 via LAN
Settings
1. Find the Wired LAN IP address of the connected projector from the OSD menu and make sure the
projector and the computer are within the same network.

Command table
Available
features differ by projector specification, input sources
, settings, etc..
Commands are working if the standby power is 0.5W or a supported baud rate of the projector is set.
Uppercase, lowercase, and a mixture of both types of characters are accepted for a command.
If a command format is illegal, it will echo Illegal format.
If a command with correct format is not valid for the projector model, it will echo Unsupported item.
If a command with correct format cannot be executed under certain condition, it will echo Block item.
If RS232 control is performed via LAN, a command works whether it starts and ends with <CR>.
All the commands and
behaviors are identical with the control through a serial port.
