Re: Differential to TTL

Thanks for the reply Martin,
I'll try this out when I get a break from work next. The MPG is only
about 10 inches from the breakout board. It actually works as is but I
just want to see if I can get the signal closer to 5v, more for learning
purposes than anything.
Regards,
Glen.
