Ziton have now introduced the new software version 4 for their ZP3 range of panels.
The panels may not look that different from the front, they have been vastly updated. This includes a USB port instead of the older style RS232 ones for the upload/downloads to a laptop.
Any panels or motherboards purchased from now on will be software version 4. You will need to have the latest version of Planner for Windows to work on these. The version of Planner that you need is 3.1.9.8
The new panels:
