| Optipac Trackball/Vortex Spinner Question... |
| (1/1) |
| JamesS:
Ok, this may be a dumb question, but here goes. Do you have to have seperate grounds and 5v's for each device, or can you use just one 5v/ground, say from the trackball? Also, does the Oscar need to have the optipac set to hi or lo? Any help would be greatly appreciated. |
| OSCAR:
As long as you get +5V & GND to the spinner optic board, that should be fine. It shouldn't be necessary to run separate power and ground wires back to the Opti-PAC if you can get them from the trackball. You can set the polarity jumper on the Opti-PAC to either Hi or Lo with my optic board, it doesn't matter. Actually, you could remove the jumper altogether, but without anything connected to the Y-axis on the Opti-PAC header, the y-axis will "float" causing the cursor to drift in the y- direction as you scroll sideways. |
