1. Connects to the projector
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 algorithm.
"admin1" = Administrator authority user-name
"panasonic" = Password corresponding to "admin1"
Hash value = "01466bc27ed8c0b7e607471580c55953"
4. Transmits the command
Transmission data = "01466bc27ed8c0b7e607471580c5595300QPW" + (CR)
Transmission data = "01466bc27ed8c0b7e607471580c5595300QPW" + (CR)
5. Receives a response.
Reception data = "00000" + (CR)
6. Disconnects the connection with the projector.
