Captive Screw
Connecting
Captive screw connectors are an added feature on the HD Extenders. The Captive screw connectors allow
you to cut cables down to a suitable length, reducing cable clutter, and provides a more reliable connection.
The captive screw connectors have a contact bar that is moved to compress the wire to 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 (see picture A) has a contact plate at the top and
must have the wires touching it for signal to pass. When wired correctly (see picture B) the signal will pass,
incorrectly (see picture C) no signal will pass.

To ensure the power cable isn’t too long, a captive screw connector has been included. The pin out (see
picture 3) and the wire configuration (see picture 4 and 5) are shown below.

For your convenience the cables do not come pre-terminated. The power cable (picture 1), will have wires
exposed. Each wire is encased in a different colored cover. A female captive screw connector for power is
included (see picture 2).
