I am trying to set up a MAP on a Nortel DMS-100. The distance is about 1400ft. EIA is not working I think it is to far. Security protocol won't allow us to use modems. I am attempting to get the Current loop setting to work so far I have had no success. I have tried Helmsman :bang: I am using a Black Box Current loop adapter. Has anyone ever gotten Current loop to work?
Thanks
Chandra
