GENII 485I Isolated RS485 Comms Card.
The GENII 485I Isolated
RS485 Comms card can only be used on Genesis II Digital Controllers. It provides
galvanic isolation of the data lines of both the Net Comms and the Global Points and the
screen connection at Terminal 91. To fit a GENII 485I card (See Figure A-10):
a. Ensure that the power to all Digital Controller connections is turned off.
b. Remove the top printed circuit board (six screws).
c. Remove all shunt links from the dual 14-way pin strip and the two shunt links from
the seven- and two-way pin strips on the bottom printed circuit board.
d. Turn the GENII 485I card over so that all the components and sockets are facing the
bottom printed circuit board.
e. Fit the GENII 485I card onto the two-way pin strip, then onto the seven- way vertical
pin strip and then onto the lower seven pins of the dual 14-way pin strip.
f. Refit the top printed circuit board of the Digital Controller.
g. Check that all the pins are in the correct position in all the sockets on the GENII 485I
card.
