Need help?Do you have a question about the BenQ LU960ST2 and is the answer not in the manual?
The BenQ LU960ST2 Projector RS232 Command Control Installation Guide details how to control a BenQ projector via RS232 from a computer. This document serves as a comprehensive guide for establishing connections, configuring settings, and utilizing a command table for various RS232 commands.
The projector offers flexible connectivity options, allowing control through an RS232 serial port with a crossover cable, via LAN, or through HDBaseT. Each method requires specific setup procedures to ensure proper communication between the computer and the projector.
For RS232 serial port control with a crossover cable, the guide provides a detailed wire arrangement and RS232 pin assignment. The wire arrangement specifies the color coding for each pin (P1 to P2), such as black for pin 1, brown for pin 2, red for pin 3, orange for pin 4, yellow for pin 5, green for pin 6, blue for pin 7, purple for pin 8, and gray for pin 9, with a drain wire for the case. The pin assignment clarifies the function of each pin on the D-Sub 9 connector: pin 1 is NC (No Connection), pin 2 is RXD (Receive Data), pin 3 is TXD (Transmit Data), pin 4 is NC, pin 5 is GND (Ground), pin 6 is NC, pin 7 is RTS (Request To Send), pin 8 is CTS (Clear To Send), and pin 9 is NC. To set up this connection, users must first identify the COM Port name in Device Manager, then select "Serial" and the corresponding COM port (e.g., COM6) in the communication software (like Tera Term), and finally configure serial port settings such as baud rate, data length, parity, stop bit, and flow control. The baud rate can be set to 9600, 14400, 19200, 38400, 57600, or 115200 bps, with the recommendation to check the projector's OSD menu for the correct baud rate. Data length is typically 8 bits, parity is none, stop bit is 1 bit, and flow control is none.
When controlling the projector via LAN, the connection involves an RJ45 port on the projector and a LAN cable connecting to a PC or laptop. The setup requires finding the wired LAN IP address of the projector from its OSD menu and ensuring both the projector and computer are on the same network. Additionally, users need to input "8000" in the TCP port # field within the communication software.
For HDBaseT control, the setup involves an HDBaseT compatible device, which includes a D-Sub 9 pin and an RJ45 port, connected to the projector's RJ45 port via a LAN cable. A PC or laptop connects to the D-Sub 9 pin of the HDBaseT device. Similar to the serial port setup, users must determine the COM Port name in Device Manager, choose "Serial" and the appropriate COM port, and then configure the serial port settings (baud rate, data length, parity, stop bit, and flow control) to match the projector's OSD menu.
The command table is a central feature, listing various functions, their types (Write/Read), operations, corresponding ASCII commands, and whether they are supported. This table allows users to send specific commands to control different aspects of the projector.
The projector can be powered on or off using the commands <CR>*pow=on#<CR> and <CR>*pow=off#<CR>, respectively. The power status can be read with <CR>*pow=?#<CR>. Source selection is extensive, covering inputs like COMPUTER/YPbPr (<CR>*sour=RGB#<CR>), HDMI (<CR>*sour=hdmi#<CR>), DisplayPort (<CR>*sour=dp#<CR>), and HDBaseT (<CR>*sour=hdbaset#<CR>).

Lens memory functions allow users to load and save up to 10 different lens memory positions. Commands like <CR>*lensload=ml#<CR> are used to load a specific memory, and <CR>*lenssave=ml#<CR> to save. The status of loaded lens memory can be read. There is also a command to reset the lens to center (<CR>*lensreset=center#<CR>).
The document emphasizes that available functions and commands may vary by model, advising users to check the specifications and user manual of their specific projector. It also notes that commands work if the standby power is 0.5W or a supported baud rate is set. Uppercase, lowercase, and mixed-case characters are accepted for commands. The system provides feedback for illegal command formats ("Illegal format"), unsupported items ("Unsupported item"), or blocked commands ("Block item") due to certain conditions. When RS232 control is performed via LAN, commands work whether they start and end with <CR>, and all commands and behaviors are identical to serial port control.
