Hi Tim and list,
I put the scope on mine last night - J9 and J10 are both 10 MHz outputs
and J8 is 1 PPS.
Does anyone know of a source for
cables for the J2/serial output or is it OK to use mini-grabbers/0.1"
plugs to a RS232 breakout ?
I built my own - had a leftover serial cable from, ironically enough, an
old GPS unit with a DB9 on it and bare wires on the other. I installed
some 2.54mm crimp connectors onto the bare wires and just plugged it in.
It is full-on RS-232 with real RS-232 signal levels, so don't
accidentally hook it up to TTL-level serial. I almost did that the
other day in my excitement to get it up and working.
Personally, I wouldn't use the mini-grabbers...but that's just me...
thanks,
ben
