Greetings,
I purchased one of the Electric-ICE trackballs from GGG.com, and with it came the Opti-Wiz encoder. I ordered a Tornado with the TTL board under the impression that I could connect the TTL board to the Opti-Wiz encoder.
After much searching, I have not found anyone doing the same thing, and I was wondering if anyone could offer any help. The Tornado TTL board is not marked, but I looked up the opti-encoders (QVE00118) datasheet. From that datasheet, I was able to derive what ground, +5V, X1, and X2 were. I wire these to the corresponding places on the OptiWiz encoder, and receive no response.
It is also interesting to note, with +5V and ground connected, I get no voltage drop across the emitters in the opti-encoders.
Any help would be greatly appreciated.
