Ok then, here's a connection diagram:



I'm using this as power supply:

Solderless MB-102 Breadboard Power Supply - Dual 5V and 3.3V DC Jack and USB New | eBay

As it can be used on a breadboard, had enough faffing about with 7805 on their own (too thick legs to fit on a breadboard). Not sure about what capacitors it's using, as it's all tiny SMD stuff.

I'm using the SPS705 unregulated power supply from Leadshine (Zapp) and used it on both the DM856 and the HBS86.

The only other thing is the setting on the DIP switches for the current, I was told by Zapp to set it to 2.1A peak, currently it's software configurable, but I can't connect to the driver as the software package from Leadshines drops the RS232 connection for some reason when I view the config of the driver.
