·
IP address: MAIN MENU → NETWORK → NETWORK STATUS
·
Port number: MAIN MENU → NETWORK → NETWORK CONTROL → COMMAND PORT
2. Receive a response message.

3. Generate 32 bytes hash value (message digest) from the following data by using the MD5 (Message Digest Algorithm 5).
"xxxxxx:yyyyy:zzzzzzzz"
·
xxxxxx: Administrator authority user-name on WEB CONTROL [default = "admin1"]
·
yyyyy: Password corresponding to above-mentioned user-name (admin1) [default = "panasonic"]
·
zzzzzzzz: 8 bytes random characters obtained from the response message
·

Example 1: Query Power "QPW"
1. Connects to the projector.
IP = 192.168.0.8, Port number = 1024
2. Receives a response.
Response = "NTCONTROL 1 1aa6c14e" + (CR)
"1aa6c14e" = 8 bytes random characters
