PJLink protocol
The network function of the projector supports PJLink class 1, and the PJLink protocol can be used to perform projector setting 
and projector status query operations from a computer.

*1 When transmitting a command which does not need a parameter, the operation (E) and parameter are not necessary.
Attention
 fIf 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.
 fWhen transmitting multiple commands, be sure to wait until 0.5 seconds h\
as 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
 fIf a command cannot be executed, the “ER401” response is sent from the projector to the computer.
 fIf an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.
 fSTX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.

*1  terminal is only for RGB signals input.
*2 Where marked "l" signals indicates in Plug and Play is compatible with EDID of projecto\
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
 fThe number of display dots is 1 280 x 800 for the PT-TW340 and PT-TW250 and 1 024 x 768 for the PT-TX400, PT-TX310, 
and PT-TX210.  
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.
 fWhen interlaced signals are connected, flicker may occur on the projected image.
