I need to download a backup of my lighting program from the processor in the image at the below link:
There is a female rs232 female connection under com link 3 on the left side of the image.
On the right bottom side of the image there is a rs232 male connection under com link 5 on the bottom.
I have a few questions:
1) Do I plug into link 3 on the left or link 5 on the right?
2) When I plug in do I need to turn the processor off?
3) Will a usb to rs232 cord work as my computer only has usb?
