Attention
 
f If a command is transmitted after the lamp starts illuminating, there ma\
y be a delay in response or the command may not be 
executed. Try sending or receiving any command after 60 seconds.
 
f When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the 
projector before sending the next command. When transmitting a command which does not need a parameter , a colon (:) is 
not necessary.
Note
 
f If a command cannot be executed, the “ER401” response is sent from the projector to the computer .
 
f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer .
 
f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.

r. Unmarked signals in Plug and 
Play may also be compliant if input terminals are written in the format list. Where Plug and Play is unmarked and nothing is 
written in the format list, difficulties in projecting image may occur even when computer and projector appear to have same 
resolution. 
*3  Pixel-Repetition signal (dot clock frequency 27.0 MHz) only.
*4  VESA CVT-RB (Reduced Blanking)-compliant.
Note
 
f The number of display dots is 1 280 x 800 for the PT-LW330 and PT-LW280 and 1 024 x 768 for the PT-LB360, PT-LB330, 
PT-LB300 and PT-LB280.  
A signal with a different resolution will be projected after converting the resolution to m\
atch the projector display.
 
f “i” added to the resolution value indicates an interlaced signal.
 
f When interlaced signals are connected, flicker may occur on the projected image.
