WPC 220 A Series • Installation Guide

The Extron WPC 220 A EU and WPC 220 A MK are wall mounted plates that accept video, audio, and HDMI signals through one
female 15-pin HD connector, one 3.5 mm tip-ring-sleeve (TRS) connector, and one female HDMI connector. The signals pass
through the units without modification and are output from the back via captive screw connectors (VGA and audio) and a female
HDMI connector on a 6 inch (15.24 cm) pigtail. The rear panel captive screw connectors take 18 AWG (1.02 mm) to 26 AWG
(0.40 mm) wires.
The two form factors are shown in the figure to
the right:

VGA Wiring

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:

1.

Run the unterminated end of the cable to the junction box.

2.

Strip away 3 inches (7.6 cm) from the end of the outer jacket of the cable.

3.

Unravel each of the coaxial shields and twist each, individually, to make
3 wires.

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).

6.

Secure the faceplate to the junction box using the screws provided (see
the figures at right).

7.

Connect the VGA input, audio input, or both.
