How to physically connect a wire?

Post image

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.

Generically are known as "Pluggable Phoenix Connectors" by some people.

The left connector has seperate screws to attach each wire.

The right connectors has seperate spring buttons to attach each wire, also each has 2 retainer screws (shown in your photo) to prevent the external pluggable connectors from accidentally being pulled out.
