Automatic Connection Break
The TCP connection will be automatically disconnected after there is no 
communication for 30 seconds after being established.
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. Bind this received 8 bytes and the Authentication 
Password and digest this data with the MD5 algorithm and add this in front of the 
commands to send.
Following is a sample if the Authentication Password is set to “password” and the 
random 8 bytes are “a572f60c”. Authentication
1) Connect the projector.
2) Receive the random 8 bytes “a572f60c” from the projector.
3) 
 Bind the random 8 bytes “a572f60c” and the Authentication Password 
“password” and it becomes “a572f60cpassword”.
4) 
 Digest this bind “a572f60cpassword” with MD5 algorithm.  
It will be “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.
• As for the transmission of the second or subsequent commands, the 
authentication data can be omitted when the same connection. NOTE
