Thought I'd post this question here in the ole Phantom forum. I'm wanting to connect a Naza Lite to a DJI vista using the S bus connection, and then using my DJI transmitter. Anyone else try this? Wiring suggestions? I'm thinking a servo wire from X2 on the Naza, signal wire to the S bus pad on the vista, but then where the other two ??? Also courious how the DJI transmitter will act, "if" I get them talking to one another. Suggestions wanted...

You can try like this : On X2 plug a servo connector, use the white or orange cable to link the S-Bus, and the Black to link the signal GND. Then link the other GND and BATT to the PMU.

After it remains TX and RX. have to be plugged on the EXP port. If i remember good the wiring is From left to right while watching the naza port 5V RX TX GND. Theoriticaly should work. Just pay attention where is the 5V before plugin TX and RX to confirm that i dont gave you false info.

Wow! Thanks for the quick replys. I'm still churning it around in my old (73) head. I do hate that smell of fried electronics, not to mention the burn mark it leaves in your wallet! Ha!
Soooo "IF" "On X2 plug a servo connector, use the white or orange cable to link the S-Bus, and the Black to link the signal GND" I'm only using 2 wires on the naza ???
Vista pads top to bottom
Red power +
Black power -  these 2 will power the vista
Yellow  UART RX
White UART TX
Black Signal GND
Yellow S Bus (DJI)

So if I plug a tabbed servo cable into the X2 of the Naza, I have from top to bottom, GND, POS, and SIGNAL on the bottom third wire. So the bottom "SIG" would go to the S-Bus pad on the vista. I'm guessing the GND, (top wire) would be for the SIG GND on the vista. Now what about the UARTS ? not needed ??? And what is the + pos terminal on the X2 of the naza ???

OK, checking out the EXP port...... cob webs starting to clear.......

Closer..... from research....
4-pin NAZA (EXP) connector (from top): Red, orange, yellow brown (V+, High, Low, GND).

gps is not canbus where its labelled low and high are actually rx and tx

Do not link +wire from EXP and X2 since Vista is already powerize. Important is to link the ground.
You can also add a capacitor between + and - of battery if it is the battery for motor.

Thanks, that's great. I'll wire it up tomorrow and we'll see. I have a bunch of old builds with Naza, APM, Naze, on and on ...... Got into this DJI digital stuff and I'm hooked.... Now giving life to old builds.

BTW I have a Naza Lite running with a Crossfire receiver, only using 3 wires to the X2 port.

Yes it uses the S-BUS port on X2. Most probably the power supply is given by the red wire. But if the crossfire has his own power supply you can cut the red one.

Still haven't tinkered anymore, YET. But soon. Wondering if I connect the S-bus and it's ground on the Vista, to the signal and ground of the Naza X2. Power each one separately for test, and see if I get any signal connection to the DJI transmitter.

OK. Wired it all up, Vista S-Bus and it's ground to signal and ground pin of Naza X2 . Powered Vista directly from 4s pack, powered Naza with PMU on X3 port. Linked DJI transmitter, goggles, Air unit. Connects to Naza Lite assistant, and all controls AND switches are working. Just needs a little calibration, but it works fine!

Hi Cooper

Would you mind sharing how you connected your Naza/pmu to the dji airunit, either an image showing pin selection or drawing, many thanks.

Hii , can you please share some pictures or diagram of your connections
