We are driving through a cable and did not make provisions to power the anode through the cable and drive the buffer on the cathode to sink and invert the signal...I guess we'll have to make a revision to provide for 5V at the anode on the external opto.

edit why is my signature appearing twice??
2nd edit WOW things are moving fast, the whole interface seems to have now changed.
