LIU (LAN Interface Unit) card. Installed on MEX-IP2 card. Provides PI (Program
Interface) connection over IP.
When the MAP card is installed, the LIU is not needed.
The LIU card enables the MEX-IP2 main control processor card to communicate with
the PI (Program Interface) over IP. Without this card, communication via the RJ-45
connector on the MEX-IP2 cannot take place, and all interaction with the PI must
occur via the KB0 RS-232 port unless a MAP card is installed. When a MAP card is
installed, communication via the RJ-45 connector on the MAP can take place and the
LIU card is redundant.
The LIU card translates the RS-232 protocol used by the KB0 to the IP protocol.
In order for the LIU to function, it is necessary to move DIP switch #1 on the front
panel of the MEX-IP2 cards to the left.
