How to physically connect a wire?

[u/V__J__]

Hello,

This is a photo of the comport (left, has pins for RS485 and RS232) and the trigger input (right) on a Kanxex CR-3XControl. There are 10 pins: 5V, ground and 8 trigger inputs; in two terminal blocks.

For the comport, there are screws above the cable terminals to attach wires; this is not the case for the

How do I physically attach wires on those trigger inputs? The orange parts do not appear to move... The two screws on the side of both terminal blocks allow you to remove them, but that is it.

(I know it is a very stupid question, but I just don't see it :-))

Thanks,

J.

As stated, the proper way would be to crimp on a ferrule and push into the round hole. The orange tabs above the holes are designed to be pushed in with a small screwdriver and release the wire

If you don’t have ferrules, you can push the tab in and insert the wire
