-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 OK, so I was using the 25 pin diagram, and translating the pin IDs. That didn't work. Sadly, neither does the 9 pin one. Same result, 0.35V between Data and Gnd.
The 9 pin one I have built on an breadboard first for checking, before soldering. Again it is picked up by OWFS, but the problem seems to be in the circuit somewhere! If anyone has ANY ideas, please let me know. Otherwise I will just go and buy the Maxim USB or Serial adaptor. Chris Paul Alfille wrote: > I've built the circuit myself.
