Partom 1.3 ghz wiring !?

[benitoculito]

Hello all, just got a Partom 1.3ghz set from banggood. I jumped straight in by cutting the molex connector off to add normal connectors, but then realised the wire colours don't match up to the cable connection, i.e. Cable 1 is for power but goes to black out of the molex, Cable 2 Power out for camera is white, yellow cable goes to red and the white comes out the molex as yellow ! Or am I ok to just solder it as normal, red/black power/ground and yellow as signal, don't really need audio. Also, on the tx, the channels start at 4 up to 9 then H then C am I missing the lower channels or are they for the lower frequency ? Any tips would be much appreciated as can't afford to fry this !

Cheers

A picture paints a thousand words...

I use these VTX all the time, but your confusing me talking about "yellow cable goes to red" and "white comes out the molex as yellow"

Take a quick pic and I'll take a look at it for you

I normally cut the wires and solder them to a servo extension for connection into an OSD, but before I tell you which colour wires to solder where, I need to know what wires YOU are talking about.

These are the only wires you need coming from the VTX mate:

Holy moly (or molex!)

I've just wired up the very same thing. But yes I'm a tad confused with what you are trying to wire up to. I wired mine up to a vortex. Simples

No Phil... you wired yours up to a Vector ;)

Thanks for the replys, I just tried soldering the vtx as normal, red/black = 12v yellow for signal but getting no picture. Hmmm

Oh no I didn't ... It's a Vextor!  :flamethrower:

I can't make head nor tail of the manual, but the system seems fairly simple although I'm getting no picture! Any ideas what the H and C channels are, any difference to them ?

[BlueFlyer]

Just as long as you leave your VRX on one channel and scan through using the VTX button till you get a picture. I tend to use CH8 on the VRX

[benitoculito]

Hmmm, still no picture, not sure. I think a good nights sleep will help, and thanks for your help Blue, will try with a fresh head tomorrow

Cheers

no probs, sleep is always a good thing :)

Right, I'm just back in from work, this thing has been playing on my mind all day ! I'm still not getting a picture! I have a 5v Bec running my möbius cam, a 12v Bec running the vtx, 12v going to vrx and signal cable going straight into goggles. Have tried all different channels and wot not, bit lost now, maybe try re soldering the video signal cable, hmmm not sure. Anyhow took a photo, first time using postimg!

There's your issue...

The mobius and vtx don't have a common ground.

in order for the video signal to get to the VTX, there needs to be a return path in the form of a GND connection.

[BlueFlyer]

Oh, and take the VTX completely out of that horrid orange box, it weighs far too much and as long as you keep the VTX in some airflow you wont get a problem with overheating so the orange "heatsink" box isn't needed.

[BlueFlyer]

the first thing I would suggest is use a proper FPV cam instead of a mobius... one that can handle 12v same as the VTX.

Failing that (if for whatever reason that isn't practical for your application) then you need to get your soldering iron out and re-do the wiring so you can power the VTX and the mobius from the same battery.
