The parcel was sitting waiting for me when I got home on Friday, opened it up and the power supplies they sent have the wrong plugs for NZ

Mounted and connected what I could anyway, went into town on Saturday to get adapters and had everything plugged in and going by lunchtime. All the lights came on as I expected, green light flashing away merrily on reciever, steady light on mini-PC.
-then I read the instructions (

) and found that a fast flashing green light may not be what I want, it means there is interference! I am sure the interference is coming from the dud usb camera up the mast. I have uninstalled the drivers etc for that camera and now the lights are flashing as they should. A red flash every few seconds shows it is receiving data from the aerial, a second green light flashing shows it is sending to the mini-PC.
So I think it is all working fine, I have sent an email off to the suppliers as they should have given me some login details so I can check, am also asking what they want to do about power supplies as the adapter solution isn't the best.
If I don't have an answer by Tuesday I might just hook up keyboard/mouse/monitor to the mini-PC and see if I can see from there. The mini-PC is about the size of an external portable hard drive - it's not the sort of thing you have setup to operate all the time - and should be set up for my location already.
