Topcon HiperV - Auxiliary Power
I am having trouble with external power and Hiper V receiver.
I have done a factory reset and uploaded the necessary firmware. All the cables and battery were provided by a Topcon supplier and fuses fitted so I cannot see an issue there.
The battery is a 12-24v lead acid battery (designed for mobility scooter) and is fully charged.
I have connected it via the 5 pin adapter, both with and without an internal battery and it still does not power on.
The receiver works fine with a fully charged internal battery.
Am I missing something? Any advice is greatly appreciated.
