WPC 220 A Series • Installation Guide

WPC 220 A MK

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 modication 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 gure to
the right:

z The WPC 220 A EU (left) mounts onto

80mm one-gang European EU junction
boxes. The plate is 3.1 inches x 3.1 inches
(81mm x 81mm).

z The WPC 220 A MK (right) mounts onto

MKtype one-gang UK electric junction
boxes. The plate is 3.35 inches 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:

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 gures at right).

7. Connect the VGA input, audio input, or both.

*Cut these wires 1 inch shorter. See the table at left.

NOTE: VGA pin 9 may be used to detect DDC

availability. Check the manual for your
display to see if this feature is required for
DDC communication. If you are unsure, do
not use the pin.

DDC and ID Bit DIP Switch Settings

The table at left below shows the function of the DIP switches. The table at right below shows how the switches
affect the monitors supported and some of the more common ID bit settings. Check the manual supplied with your
display to see if ID bit termination is required by your AV system. If you are unsure, set all switches to off.

NOTE: If DDC is to be used, switches 1 and 3 must be set to on and switches 2 and 4 must be set to off.

HDMI Connections

1. Run a HDMI cable from the HDMI display to the junction box.

2. Connect the cable to the rear panel HDMI connector. The rear panel HDMI connector is on a 6 inch (15.24 cm) pigtail, which

provides extra exibility to make the connection in the limited space of the junction box.

3. Connect a HDMI source to the front panel HDMI connector.
