Hi All,
Ancient modeller new to FPV, I managed to fry two video transmitters so clearly, I'm not reading something right.
The set of is a Cyclops Storm OSD and a Quanum 58-2 video TX. Turnigy HS1177 camera. (everything is capable of using 3s lipos) Separate 3s Lipos, one for video and one for main motor power
Looking at the vid TX terminals, from left to right we have:-
1 Live. 2 Ground. (7-20volt) 3 Video in. 4 Ground. 5 Live (5 volt)
Now in my innocence I took the video out lead from the OSD and used only the right hand three pins. I now think that I've put the full 3s lipo voltage in through the 5 volt pins (which I now realise is meant to power a 5v camera)
Can anyone confirm as follows
The pins to be used when powering the video transmitter from the OSD should be 1, 2 and 3. 3 being video in.
That the 5 volt live is not used
That the ground next to the 5 volt live is also not used
I have taken the OSD out of the system and powered the Vid TX directly and that has worked fine. I have read the instructions for the OSD which refers to a jumper and shorting out pins on the OSD, depending on whether I use a separate battery for the OSD or use the main power batteries for everything and managed to fry my own head.
Before I let the smoke out of another £25 vid TX I need to sort this out for sure.
Thanks all

The safest route (I think) would be just to confirm the pin voltages with a cheap multimeter before you wire things up after the OSD.
What you're saying sounds correct, but just to be sure just check the pins and you won't go wrong :)
Steve, Blueflyer, Thanks very much, that's just what I needed to know. I wasn't sure if the two grounds needed to be connected together but I'm sufficiently confident to give it a try now.
Ta muchly,
