Overview
1. Since 12 series FHD model, LAN Control function is available with LAN board installation. There are
two types of controlling as follows.
1)Command Control
LAN Control function of the unit can control the unit in the same way as serial control from a network.
2)PJLink Protocol
LAN Control function of the unit confirms with PJLink™ class 1and you can operate PDP from your
computer using PJLink protocol.
2. You need to develop the application to use those function. VDBG doesn’t provide the application, please
develop it by using this manual.

Authentication
LAN Control function has authentication for accessing control. The authentication key has to be created
by “MD5” algorithm at PC and PDP separately. Those authentication keys will be matched when PDP
command has been transmitted. If they are the same, PDP execute the command. If not, PDP
terminates the connection.
PDP address is 192.168.0.8
