 The LCD panel used in the LCD projector consists of hundreds of thousands of fine pixels. Like other video display 
devices, the LCD panel may contain bad pixels which do not operate. When shipping a product, the conditions for 
identifying bad pixels and the number of bad pixels that a LCD panel is allowed to contain are strictly managed in 
accordance with the relevant specified standards by the  LCD panel manufacturer and our company. Though a screen 
may have some dead pixels, this does not affect the  overall screen quality and the lifetime of the product.

6-2 RS232C Command Table
Communication Format (Complies with the RS232C Standard)
• Baud rate : 9,600 bps 
• parity : None
• Data bits : 8, stop bit : 1
• Flow Control : None
Serial Communication Protocol
1.Command Packet Structure [7bytes]
• A command packet consists of 7 bytes in total.
• The two bytes 0x08 and 0x22 signify that  the packet is for serial communication.
• The following 4 bytes represent a pre-defined  command that can be defined by the user.
• The last byte is the checksum which checks the validity of the current packet.
• Header [2 Byte]: Pre-defined values fixed to 0x08 and 0x22.
• Cmd1 [1 Byte]: The first value of the code  defined in the command list (Hexadecimal)
• Cmd2 [1 Byte]: The second value of the code defined in the command list (Hexadecimal)
• Cmd3 [1 Byte]: The third value of the code defined in the command list (Hexadecimal)
• Value [1 Byte]: Input parameter for the command (Default: 0) (Hexadecimal)
• CS [1 Byte]: Checksum (the 2’s complement of the  sum of all the values except for the CS value.)
2. Response Packet Structure [3 Bytes]
1.Success
2. Fail
• When the received packet from an external device has a valid value, a Success packet is sent. Otherwise, a Fail  packet is sent.
• A Fail packet is sent if: • The received packet length is not equal to 7 bytes.
• The 2 byte packet header value is not equal to 0x08, 0x22.
• The check sum is incorrect.
• Failure detection by an external device • An external device classifies the packet as Fail  if it does not receive a Success packet within 100ms.
