Connections and communication settings
On-screen images in this document are for reference only. The screens may vary depending on your Operating System,
I/O ports used for connection, and the specifications of the connected projector.
PC or laptop
Communication cable (crossover)
D-Sub 9 pin (female)
D-Sub 9 pin (male) on a projector
Choose one of the connections and set up properly before RS232 control.
RS232 serial port with a crossover cable
Settings
1. Determine the COM Port name used for the RS232 communications in Device Manager.
4
2. Choose Serial and the corresponding COM port as the communication port. In this given example,
Baud rate
9600 / 14400 / 19200 / 38400 / 57600 / 115200 bps
Check the baud rate of the connected projector from its OSD menu.
Data length
8 bit
Parity check
None
Stop bit
1 bit
Flow control
None
COM6 is selected.
3. Finish Serial port setup.

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.
2. Input 8000 in the TCP port # field.
RS232 via HDBaseT
Settings
1. Determine the COM Port name used for the RS232 communications in Device Manager.
2. Choose Serial and the corresponding COM port as the communication port. In this given example,
COM6 is selected.
6
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.
Data length

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.
