Connecting a CAT to a Vertex-5000 Repeater

The Yaesu Vertex VXR-5000 repeater has a DB-25 accessory connector on the rear panel. The NSQ DET and TONE outputs are open collector transistors and will require 2200 ohn pull-up resistor. Note: Dip-switch #1 needs to be on placing the controller into a negative-going COR mode.
