My first Lynx Express passed self-test today - on to build the second one. My dongle is soldered up, but untested so far, probably should try it next without waiting for the official case. Thanks to everyone involved with the manual - between the text and the video, things went well. The second one should look better.
I did manage to lose one 3023 optocoupler and smash a pin on one of the RS-485 chips, so I'll need to replace them before I can get two boards working simultaneously. My local Frys wasn't much help. Should I try hard to get identical replacment parts, or can I substitute? Worst case, I pay Mouser $1.78 plus $7 shipping.
Now, where do I find 32 cheap cords ...
