It works fine with the hyperterminal now. The printed board had a flaw in it and I had to re-soldered a connection. Can you tell me what the output for channel A & B are supposed to look like. I'm trying to hook up an optical encoder and I'd like to know what your interface is looking for. Thanks again Dave,

Check out the troubleshooting steps on the construction page and make sure all the parts are installed correctly, all the soldering is good (check the solder side of the board with a magnifying glass), cables are connected correctly, voltages are what they need to be, etc. The PIC shouldn't get hot (but may warm a little).

How do I check this out? Any ideas, I'm kinda new at this. All I can tell you is that the PIC gets hot and your software doesn't recognize the encoder hardware. I've downloaded ASCOM 5.5.1 and your driver and DSC. Dave, trying this with vista and having no success. How do I check this out? Any ideas, I’m kinda new at this.

This was looking bad until I decided that "If it ain't talking, maybe the out is in?" I switched the pins for the USB tx/rx and all works now! Whew! Looks like a winner in my book, though I dont yet have the encoders for the full trial. You may want to let Jimbo know that on the bottom left of his schematic (red marked-up one), the "pin 6" and "pin 18" are on the wrong pins, per his actual connections. (see his later pic of the soldered connector) -Matt OK thanks.

Before soldering, I am trying it on a breadboard...to no avail yet. The Laptop recognizes it, but I am getting no response via the Hyperterminal testing. That being said, I am just trying to get a response, since I wont get my decoders in for a few weeks. Should the circuit respond without the encoders attached? I'll email a link to a snapshot of it wired up. Yes, I am trying this, but no luck so far. Before soldering, I am trying it on a breadboard…to no avail yet.
