so the ground will register 3.3v as well as the positive correct?
-
Touch black to the ground pin and red to the positive pin at the same time, you'll see +3.3v (or -3.3v if you have them mixed up).
Easy way to do it is to leave the black on the first pin, then check each of the 3 remaining pins with red.
Move the black up to the next pin, then check the remaining two with red.
Move the black up to the second-to-last pin and check the last with red.

got it, will let you know tomorrow what i find out.

Oh you guys are awesome! I picked one up here at cup and once I get home I'll rig up an arduino to that TX/RX and see what we can get.

Arduinos signal at 5v while this will be 3.3v, make sure you drop that voltage.

My bad, I think my newbishness with electronics gave the wrong impression.
The 4 wire connector on the virtue is something like this <gnd, Vcc, tx, rx> right?
So if I hook an arduino digital input to the tx and rx, I should be able to log the signal switching correct?

Yes, but it will be using serial voltages and not TTL voltages. You need a level converter or some resistors to keep from damaging the chrony. It's cheaper, easier and safer just to use that ebay link I posted :P

So if I'm reading the info on these converters right, I need a terminal emulator to get the raw data from the USB port? I'm so far out of my knowledge base right now but I love learning this stuff.

Subbed because I want to stream my clock data.

Here are my pin voltage tests.

By your procedure you are suggesting that pin 2 is ground and pin 4 is power?
