Go for it! If you want to test it before setting it up (although connecting
it to your Omni is so-o--o-o easy), put +5 V to the + pin, and ground to
the - pin, and look at the Phase A and Phase B outputs on your
oscilloscope. When you twirl the knob, it'll generate a square wave pulse
train. Be sure it does this for both directions (both phases). If so, it
works. Do what i did and hook it up. Lotsa fun!

> I recall reading recently about several of you using various optical

> I've found an optical encoder in my "good junk" box. It's a Hewlett
> Packard "HRPG-ASCA #14C." Below that is "90 07" (could be date of Mfg.)
> It's a miniature panel mount optical encoder. Has a 5 conductor flat
> cable and 5 pin female connector. I have spec. booklet w/dimensions.
> Anyone know if this is suitable for TenTec applications earlier
> Any info anyone?
