Recommended Wiring
Procedure
Arrange the large connector on the left as shown in the
diagram, with the white polarising key at the bottom.
Working from the
bottom of the connector, connect the first wire (which is grey or purple)
to the male connector on the ground harness. This wire connects, via the
harness, to the COM contact on all switches, in a "daisy-chain"
arrangement.
Separate the rest of the wires into 3 groups. Start each group
with the green and blue wires (bottom) and end with the purple and grey wires
(top). You can ty-wrap the 3 groups close to the connector if you wish, or just
lay the groups across the panel.
Now the wires from each group can be
connected to the correct switches as shown on the diagram above. The table
below may help, as this presents the connections in switch order and shows only
the commonly-used switches
Then connect the ground harness to the other
contact of each switch. Run along the controls in the most convenient path. You
can miss out a connector if you need a longer routing as there are spares. Cut
off the extra length.
Connect the three other plugs to the trackball and
spinner as shown.
Ty-Wrap all wiring for neatness.
Reversing
Trackball Axis
If you find one of the trackball axes moves "backwards",
the resolution is to swap the TX1 and TX2 wires over (or TY1 and TY2). To do
this, consult the diagram above and locate the correct pair of wires, at the
main 40 way plug. The wire and contact can be removed from the black housing by
carefully lifting the small tab on the side of the housing and pulling out.
Swapping the pair of wires will reverse the direction of that
axis.
Connecting a Slikstik Spinner
The Slikstik Spinner, with
TTL opto-board can be plugged into the Spinner connector. Before doing this,
check the colors of the wires at the spinner plug. They should be as shown in
the diagram above. You might need to swap over two wires if your harness is
configured for the Oscar spinner (which is no longer available). To do this,
pres on the contact tab through the slot in the side of the white housing and
pull out the wire and contact as needed, and re-insert in the correct
slot.
Other Troubleshooting Tips
All of the information on the
I-PAC applies to the Mini-PAC. The LED indications are the same, all
troubleshooting information applies, so check out the I-PAC pages for further
information.
Mounting:
A good method of mounting the board is
to use only two of the feet from our PCB Feet kit and fit these to the two
holes nearest the harness connector. The board may need to be mounted in the
centre of the panel if it is especially large, to allow the harness to reach.
Wires of 320mm length will allow for approx 640mm between furthest mounted
switches.
