Well I did a lil’ lookin’ and I don’t think this will be much help, especially after reading your latest post. I could not find anything that states output towards the customer in the form of voltage…

There are VERY rare examples of units that can put a very small amount of voltage out to power a shelf. That was in the range of 2 v p-p.

Everything for the output of DS1 smart-jacks are really stated in the form of dB (decibels) those can range from -0.0 dB to -15 dB outputs.

I did a couple calculations to come up with:
-0.0 dB = about .77 Vrms
-7.5 dB = about .32 Vrms
-15 dB = about .13 Vrms

A VOM is really not an accurate measurement at all really to determine quality of the signal.
