Utility Voltage on Genmon

[garybixler]

H,i just installed Genmon on my Generac Evolution generator. The only thing is that the utility line voltage isn't displayed. Shows 0 volts. The utility voltage parameter is shown in Nodelink but is just blank. I am running Nodelink version 0.9.36.  

Thanks for any info.

I found Line Voltage in the Nodelink log marked in red.
