VGA Wiring

WPC 160 A Series • Installation Guide

The Extron WPC 160 A EU and WPC 160 A MK are wall mounted plates that accept video, audio, and USB signals through one female 15-pin HD connector, one 3.5 mm tip-ring-sleeve (TRS) connector, and one USB B connector. The signals pass through the unit without modification and are output from the back via captive screw connectors. The captive screw connectors take wires from 18 AWG (1.02 mm) to 26 AWG (0.40 mm).

The two form factors are shown in the figure at right:

zz The WPC 160 A EU (left) mounts onto 80 mm one-gang European EU junction boxes. The plate is

3.1inches x 3.1 inches

(81 mm x 81 mm).

zz The WPC 160 A MK (right) mounts onto MK type one‑gang UK electric junction boxes. The plate is

3.35inches x 3.35 inches (85 mm x 85 mm).

NOTE: Extron recommends Extron MHRVGA bulk cable (part number

22‑024‑01) or assembled cables (part numbers 26‑112‑15, 26‑112‑36,

26‑238‑01, and 26‑238‑25). The wire colors for these products are

shown in the VGA Connections table at the top of the next page. If other

cable products are used, the colors may not correspond to those shown

in the table.

The DDC and ID bit DIP switches, the +5 V pin, and the DDC pins are optional but they can affect the monitors supported by the system (see the table to the right of “DDC and ID Bit DIP Switch Settings” on the next page).

To connect wires from the VGA input to these modules, some wires must be cut shorter than others (see the table in the “VGA Connections” section on the next page). Follow these instructions:

4.Cut 1 inch (2.5 cm) from the end of the individual wires marked with an asterisk in the VGA Connections table on the next page.

5.Strip 3/16 inches (5 mm) of the inner jacket from the end of each wire and secure the wire to the appropriate captive screw connector (see the VGA Connections and TRS Connections tables on the next page).
