First off I want to thank Skyler he is the only one that reached out to me today as i am struggling with figuring out the pin outs on this particular setup.. I am going to rewrite this question here a little bit.. First off we are looking to do take the TX side of a duplex cable from uricables and place spacer pins or Ethernet solid core wire in the pins to go to the JT270M With Skylers Help i have come up with the pins on the Maxtrac that should be forwarded I think but not too sure.. 2,3,7, However what pin placement should they go on in the mic connector.. Also Their is a few more options it looks like and not exactly sure what to pick from.. Here is the link where i was sent . http://radioaficion.com/cms/wp-content/uploads/2015/07/Leixen_VV-898_Microph... So.. I am not out at the repeater site so I have no clue what pins are taken and not on the TX side of that cable.. Anyone that can lead me to a better direction as to which pins to cross and where that would be great..
