I have now mounted all components on the MIDI2VC PCB. It pretty much works as expected. I had done a couple of errors on the DIN5 footprint and generally the MIDI in circuitry. This has now been fixed by patching and using chassis mount DIN5 connector. A problem persists, however, and that is symbols being dropped in the opto coupler. I've checked and rechecked the circuitry and the data sheets but cannot find any errors. It is difficult to trouble shoot this with an analog scope, so I may have to hunt this one down with a digital scope, if I can only borrow one.. I can always take a trip to work I guess .. :)
