Trying to add a 2nd GLS10. Both my units, 1222 and 8612 would not recognize the new GLS10. I thought it was a bad unit but the more I switch cables and trandsucer discovered it is the Network cable. My original network cable,(all 1 piece) works on both GLS10. As soon as I try the new 2 piece cable, it does not work and recognize at all. I got this cable from Sonar pros and thought it was the correct one. The have blue connectors. Am I missing something?
