Trackball help please - old model, not sure how to connect

[timsatari]

Hi all - moving through my very long-term old project and need some guidance please in relation to the trackball.

Truth is, I can't even remember where I purchased it from (maybe 10 years ago) and wish to use it now if possible.

Please see the images, the underside of the installed unit, it has 2 x 4 pin connectors.. I've taken one out to show the board.

How / what do I connect these to? I have two 4 pin connectors in my kit too... any assistance appreciated.

I have one of these. I think maybe Ultimarc sold them for a short while. Anyway, I've attached a picture. The outside wires are 5v (red) and ground (black). The inside 2 wires are x/y take a look at the photo ive attached.

The wires themselves need to be attached to something like an OptiPac or Opti-Wiz or some other trackball/spinner encoder board.

Found this pinout and note on the Ultimarc OptiPac page here, "installation" tab.

The track side of the PCB should look like this. If it is the "special" type for Mini-PAC it will have two extra resistors added to this side.

As Mahuti indicated, you'll need an optical encoder:
- Ultimarc Opti-Pac
- GGG OptiWiz
- Ultimarc I-Pac2 (2015 or newer)
- Ultimarc Mini-Pac
- Arduino with mouse firmware
