Martin it's people like you who make the world a better place to live in thank you.

Many thanks, Jim! Any idea what the output levels are?

I don't know that there's an actual "spec sheet" - there's some discussion on the list a few months ago, with respect to "what might burn it out". On port 1 (the receive port, port 0 is the

Okay, thanks. I'll try it out later. Regards, Jason
