Cendence/Focus2/gps connections

[Greginaustin]

I posted this in the DJI forums but I'll try here too, I can't figure it out and searches aren't helping me much:

I have an I2 with a Cendence, which has the patch antenna. I'm having issues trying to figure out which order the antenna, focus handwheel 2, and gps module should connect. The gps module and the patch antenna each has an inline port and the focus does not. Depending on how I connect it, either the focus just flashes and doesn't show up in the app, or i get a "Patch antenna not detected" in the Cendence display. What's the correct connection order?

*edit: by inline port, I mean the CAN port.

Hi @Greginaustin, just sent you a PM for some further discussion and will also post back here with some updates for all.

One piece of information you did not specify was what you are using for your display, CrystalSky or another device? If you are using CS you can forgo the GPS Module as the internal GPS on the CS allows you to use Dynamic Home Point (DHP). If you are using an iPad or Android device you would therefore need to be using the GPS Module for DHP to be enabled. If the latter is the case I am having one of my colleagues check with our resources at DJI to inquire on the proper connection order.

Upon further troubleshooting, I've come up with this.

1) Patch Antenna alone works ("Patch Antenna Detected")
2) Patch Antenna with GPS module hooked to it's inline CAN port works ("Patch Antenna Detected")
3) GPS Module alone works
4) Focus Handwheel 2 alone works
5) Focus Handwheel 2 plugged into GPS Module inline CAN port -- both work
6) Focus Handwheel 2 plugged into Patch Antenna inline CAN port -- both work
7) Focus plugged into Patch plugged into GPS -- Focus and Patch don't work ("Patch Antenna Not Detected")
8) Focus plugged into GPS plugged into Patch -- nothing works ( nothing on Cendence's screen about Patch antenna)
