PJLink security authentication

The PJLink password can be set from the [NETWORK] menu → [PJLink PASSWORD] ( x page 90) or from the

[Set up passwords] page ( x page 115) when accessing from the web.

The PJLink password is not essential for the PJLink control, which is available even the PJLink password is left blank (factory default setting).

f For specifications related to PJLink, refer to the website of Japan Business Machine and Information System

Industries Association.

Note f The projector automatically disconnects from the network immediately after sending the command. Such specifications are made from the viewpoint of security, such as prevention of illegal operation of the projector by a malicious third party. To send commands continuously, make a request for network connection every time and send it. For details, see “Communication flow between the server and the client”

( x page 134).

Communication flow between the server and the client

When sending / receiving commands via LAN, refer to the communication flow shown below.

Attention f If a command is transmitted after the light source starts illuminating, there may 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 ID transmission in RS-232C supports ZZ (ALL) and 01 to 06.

f If a command is sent with a specified ID, a response will be sent to the computer only in the following cases.

g It matches the projector ID g When [PROJECTOR ID] ( x page 77) on the projector is [ALL] f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.

*1 Where marked " l " signals indicates in Plug and Play is compatible with EDID of projector. 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.

*2 Pixel-Repetition signal (dot clock frequency 27.0 MHz) only.

*3 When a 1125 (1035)/60i signal was input, it is displayed as a 1125 (1080)/60i signal.

*4 VESA CVT-RB (Reduced Blanking)-compliant.

*5 Only for PT-LW376 and PT-LW336.

*6 The signal with 1/1.001x vertical scanning frequency is also supported.

Note f The number of display dots is 1 280 x 800 for the PT-LW376 and PT-LW336 and 1 024 x 768 for the PT-LB426, PT-LB386 , PT-LB356 and

PT-LB306.

A signal with a different resolution will be projected after converting the resolution to match 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.

f The image may not be displayed in full screen according to the computer output setting.
