[CA] e127 not recognizing radar

[Tony T]

Thank you ... The HD Radar dome connects to the rear on the e127 vie the "raynet " plug / port. There are two of these ports on this unit and have tried them both. The connector at the rear of the e127 has a number of pins more than the connector at the HD18 Radar dome .. The Dome connector has 6 pins. .. (2 for power and 4 others ) Is there a way to check the cable ?? I have 12vdc on the two center pins. I have found continuity from the 4 outside pins to 4 pins on the e127 side . Do I need any continuity on the other pins on the e127 side ?
Thank you
