A.3 OmniLink 5000 Upgrade Procedure
Most OmniLink 5000 press controls shipped
prior to July 1998 will need to have a hardware
upgrade to work with LinkNet. This upgrade
consists of replacing the old back plate and
communications card on the operator interface
terminal with a new back plate and communications
card.
To determine which kind of communications
board is installed, look at the back of the OmniLink
operator interface terminal (the box with the display
screen on it - also called the OIT). There should be
5 connectors on the back of the OIT if a new
communications board is installed (see Figure A.3).
If only 4 connectors are present, then an older
communications board is installed (see Figure A.4)
and will need to be upgraded. Even if the new
communications board is present, the press control
may need a software upgrade. It’s a good idea to
check with Link before installing LinkNet.

A.3.1 OmniLink OIT Communications Board
Upgrade Procedure
This procedure is for replacing an old
communications board and back plate with a new
communications board and back plate. Refer to
Figure A.5 for the following steps:
@
Remove power from the OmniLink card rack
and
the OIT.
@
Remove the screws from the back panel of the
OIT, and remove the back plate. Note that there
is a ribbon cable connecting the circuit board on
the back plate to the OIT circuit board in the
can. Disconnect the ribbon cable from the
circuit board on the back panel.
@
Using the cable assembly supplied with the
upgrade kit, connect wire A of the cable to
terminal A on the OIT, and wire B of the cable
to terminal B on the OIT. Do not disconnect
the wires going to the card rack (there will be
two wires each in the A and B positions of the
terminal strip on the OIT circuit board).
@
Connect the ribbon cable between the display
board and the new communication board.
@
If not already plugged in, connect the cable
supplied with the upgrade kit to port 1 of the
new communications board. This is the only
port on the inside of the back panel.
@
Install the back panel on the Operator Terminal.
