Rather than start a new thread, I thought I'd update this one with latest...
The first night showed some flickering of the red LED on the mount when slewing, and so I thought there was an issue.
After some investigation with Andrew and Bill at Optics Central in Mitcham it turns out that the Version 5 Synscan handset shows 1VDC less than the version 4 handsets. (this is the voltage shown in Utilities menu on the handset). Andrew will investigate further with Saxon, but we were thinking that the addition of a USB port on the hand controller might explain the voltage drop.
In the limited time I've spent with the mount there are no issues with slewing or tracking using the 12V 10A power supply, even though the voltage drops to around 11.3 and even down to 10.9V momentarily when slewing on both axis. The flickering LED has stopped after removing the DC-side extension cord.
Perhaps the voltage on the controller board is still 1V higher than what the handset is showing?
Anyway, will keep testing and see what Saxon come back with.
Cheers
Stephen
