Captive Screw
Connecting
Captive screw connectors are an added feature on the UHD-H2H-44M matrix. The captive screw
connectors allow you to cut cables down to a suitable length, reducing cable clutter while providing
a more reliable connection.
The captive screw connectors have
a contact bar that is adjusted to
compress the wire against the
top contact plate. Use the screws
at the top of the connector to
compress the wire against the
contact plate.
When connecting the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly
(see picture A)
the signal will pass,
incorrectly
(see picture B)
no signal will pass.

ports and connect to third party control systems.
