I’m currently using an Ag Leader Integra / GPS 7500 for VR fertilizer spreading via serial control of a Raven 660. The speed signal for the 660 has been coming from an Outback lightbar; however, I am getting an external lightbar (L160) for the Integra. With this change, I planned to pull a speed signal from the “Speed Out” connector on the 7500 harness for the Raven controller.
I happened to have spare connectors, so I put together my own cable to connect to the 660. However, on testing the cable, I am not getting a speed readout on the 660. Are there setting changes I need to make in either monitor, or do I need more than a simple 2-wire cable? Or am I on the wrong track entirely?
