3. Management with Web browser software
3.6 Command Control via the Network (continued)
Automatic Connection Break
The TCP connection will automatically disconnect after 30 seconds with no
communication.
The projector does not accept commands without authentication success
when authentication is enabled. The projector uses a challenge response type
authentication with an MD5 (Message Digest 5) algorithm.
When the projector is using a LAN, a random 8 bytes will be returned if
authentication is enabled. Combine the 8 bytes received and the Authentication
Password and use this data with the MD5 algorithm. Add this in front of the send
commands.
For example, if the Authentication Password is set to “password” and the random
8 bytes are “a572f60c”.
Authentication
1) Select the projector.
2) Receive the random 8 bytes “a572f60c” from the projector.
3) Combine the random 8 bytes “a572f60c” and the Authentication Password
“password” to create “a572f60cpassword”.
4) Use this combination “a572f60cpassword” with the MD5 algorithm.
It will become “e3d97429adffa11bce1f7275813d4bde”.
5) Add this “e3d97429adffa11bce1f7275813d4bde” in front of the commands
and send the data.
Send “e3d97429adffa11bce1f7275813d4bde”+command.
6) When the sending data is correct, the command will be performed and the
reply data will be returned. Otherwise, an authentication error will be returned.
• Regarding the second and subsequent commands, the authentication
data can be omitted when using the same connection.
