I did a search on the LEMO connector and didn't see much on it. I am upgrading to a Zulu headset and want to re-wire for the LEMO option which will combine the phone, mic and power functions. Currently I have a battery-powered Lightspeed 3G 30 with separate plugs for phone and mic. I am trying to decide whether to make the power pin "hot" or wired through the master. I am looking for input on which would be the better way to go. Anyone have any thoughts on this?
