9. Attention
・ If a command is transmitted after the lamp 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.
・ 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.
・ It might take time by the time the response returns because the command is processed in the projector.
Set the time-out to 10 seconds or longer.
・ When multiple projectors are all controlled
1) Set a different ID for each projector
2) Set [RESPONSE(ID ALL)] to [ON] in only one projector
3) Set [RESPONSE(ID ALL)] to [OFF] for all other projectors set in Step 2)
・ When multiple projectors are all controlled by group unit
1) Set a different ID for each projector
2) Set [RESPONSE(ID GROUP)] to [ON] in only one projector
3) Set [RESPONSE(ID GROUP)] to [OFF] for all other projectors set in Step 2)
4. 2. Control through LAN terminal
Connection and command transmission changes depending on mode (admin password is set or not with web control).
Control according to the procedure in "4.2.2" on the protection mode (the password is set), and according to the
procedure in "4.2.3" on the unprotected mode (the password is not set).

4. 2. 2. When Web control administrator rights password is set (Protect mode)
4. 2. 2. 1. Connecting
4. 2. 2. 1. Connecting
1. Obtain the IP address and port number (Initial setting value = 1024) of the projector and request for a connection
to the projector.
You can obtain both the IP address and the port number from the menu screen of the projector.
・
: Obtain from the main menu → [NETWORK] → [NETWORK STATUS]
・
: Obtain from the main menu → [NETWORK] → [NETWORK CONTROL] → [COMMAND PORT]
2. Check the response from the projector
・ Response data
Mode: 1 = Protect mode
3. Generate a 32-byte hash value from the following data using MD5 algorithm.
“xxxxxx:yyyyy:zzzzzzzz”
Administrator rights user name for Web control (default user name is “admin1”)
Password of above administrator rights user (default password is “panasonic”)
8-byte random number obtained in Step 2)

“ERR2”
Out of parameter range
“ERR3”
Busy state or no-acceptable period
“ERR4”

Wrong data length
“ERRA”
Password mismatch
Example: Query Power "QPW"
1. Connects to the projector
IP = 192.168.0.8 port = 1024
2. Receives a response
Response = "NTCONTROL 1 1aa6c14e" + (CR)
"1aa6c14e" = 8 bytes random characters
3. Generates a hash value (message digest) from "admin1:panasonic:1aa6c14e" by using the MD5 algorism.
"admin1" = Administrator authority user-name
"panasonic" = Password corresponding to "admin1"
Hash value = "01466bc27ed8c0b7e607471580c55953"
4. Transmits the command
Transmission data = "01466bc27ed8c0b7e607471580c5595300QPW" + (CR)
5. Receives a response.
Reception data = "00000" + (CR)
6. Disconnects the connection with the projector.
