SECTION 1 SERVICE INFORMATION
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.
4. 2. Control through LAN terminal
Possible to control this projector by connecting PC to the LAN terminal on this projector.
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. 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.
- IP address : Obtain from the main menu → [NETWORK] → [NETWORK STATUS]
- Port number : Obtain from the main menu → [NETWORK] → [NETWORK CONTROL] → [COMMAND PORT]
2. Check the response from the projector

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 algorithm.
"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.
