Following Hermes_User_Manual_V1.16.pdf, straps set as follows:-
JP4 2 -> 3 Mic wired to Tip
JP5 2 -> 3 -"-
JP6 1 -> 2 PTT wired to Ring
Measuring +3.3V on Ring which should be PTT and 0V on Tip which should
be Mic Bias.
From the labelled picture Pin 1 is the one farthest away from the
labels Jp4, JP5 and JP6.
Should Pin 1 be nearest the labels?
73 ... Sid.
