2.7.3 INTERFACE BOARD

The interface board, located above the PCM, stores all the source, screen, MCGD and TCGD
information, and the projector's IP address. A software upgrade may be necessary when installing an
new interface board; therefore, backup all information before replacing the module and load it onto the
new board. NOTE: The IP address should never need to be set on a replacement board because the
PCM automatically resets it. If the PCM is unable to communicate with the interface board, then the
PCM sets the interface board's IP address using the serial connection. After the IP address is changed,
communication is established between the PCM and interface board.
