QSControl.net™ Wall Control Plate Accessories
I. INTRODUCTION
The WCP-1 and WCP-2 are wall control plate accessories for QSControl.net
network audio system components, such as Basis, RAVE, and DSP
products. They allow an installer to create simple, non-computer user
interfaces for these products in sound systems. As a result, end users
don’t need to learn the QSControl.net software or anything technical about
the system to adjust volume, select audio sources, choose presets or
snapshots, or other control functions.
The WCP accessories connect to one or more of the unit’s OmniPort
inputs, which accept both analog control input via variable DC voltage or
variable resistance and digital control input via TTL-type logic.
The WCP accessories provide two ways to connect to the QSControl.net
unit: an RJ-45 jack, for use with Cat 5 or Cat 6 network cable, or a screw
terminal strip for use with individual wires.
Note: You must assign any
functions to their respective OmniPort inputs in the QSControl.net
VenueManager application.
Mounting
The WCP accessories mount in the type of plastic A/V wall box
commonly used in North America. They fit any Decora™-style trim plate.
The front panels have spaces for labeling functions, names, etc. Each
accessory comes with a sheet of labels printed with commonly used terms.
If you mount a WCP accessory in a metal electrical box, you may have
difficulty plugging a cable into the RJ-45 jack on the back of the
accessory.

The control element of the WCP-1 is a 10 kΩlinear taper potentiometer
with 11 detents marked 0 (fully counterclockwise) to 10 (clockwise). It
connects to any OmniPort on the QSControl.net unit and can be wired so
that maximum resistance is at full clockwise
or at full counterclockwise.
Figures 1–4 depict how to connect the WCP-1 to an OmniPort.

The WCP-2 uses a six-position binary-coded decimal rotary switch. It
connects to two (up to four usable positions) or three (up to six usable
positions) OmniPorts on the QSControl.net unit. The OmniPorts must be
configured for binary use in the VenueManager application. It is ideal for
such functions as selecting signal sources, selecting presets, and routing
signals. The truth table is at right. For reliability of interfacing with the
OmniPorts, there is no “0” position where all outputs are open.
Figures 7 and 8 depict the connection of a WCP-2 to an OmniPort.

Non-QSControl.net applications
The WCP-1 can be used for non-QSControl.net analog applications, such
as variable passive signal attenuation or a variable voltage divider (see
Figure 5). The WCP-1 has two circuit board locations where you can
mount resistors to adjust the full clockwise and/or counterclockwise
values of the resistances and thereby change the range of attenuation or
voltage variation from minimum to maximum. A resistor in position R1
will add that amount of resistance to the fully counterclockwise position,
while a resistor at R2 will add resistance to the fully clockwise position.
To mount a resistor in R1 or R2, first cut the printed circuit board trace at
the desired location (see Figure 6). Then insert the resistor and solder it
into place, and trim any excess leads.
Connections
For typical control voltage and signal attenuation applications, the CW
terminal would serve as the input; the wiper terminal, as the output; and
the
CCW terminal, as the common.
