RCWPB4

Wallplate Control Interface for DM Series

TECHNICAL DATA

The RCWPB4 is a control interface for Lectrosonics DM
Series processors to provide a variety of remote control
operations. The unit is connected to the 25-pin D-sub
connector on the rear panel of a DM Series processor. As
each button is pressed, an operation is triggered on the
processor and the LED on the wallplate illuminates.

The most common use is to make changes in the setup of
a DM Series processor by launching macros and recalling
presets. When the button is pressed the associated LED
lights up and stays lit until another button is pressed so
that the LED indicates the current state of the processor.
Applications such as room combining are easily accom­plished with preset recalls from a single button press.

Basic Operation

Pressing buttons B1 thru B4 will send a pulse to the cor­responding connector terminal and light the associated
LED (L1 thru L4 respectively) and turn off all other LEDs.
If the same button is repeatedly pressed, a pulse will
be sent to the DM system at each press, and the cor­responding LED will remain lit; it does not toggle. For this
reason, the RCWPB4 is intended to be used as a “State
Indicator” showing the user which state was last executed.
Space has been provided next to each LED for labeling.

External LED Control

As an alternate configuration, you can use connector pins
6 and 7 to allow a DM processor to control LED’s 1 & 3
instead of button presses on the RCWPB4 itself. This will
allow the LEDs to indicate events that occur in the DM
processor. To configure the unit for this mode, remove the
corresponding jumper EXT 1 (for LED 1) or EXT 2 (for
LED 3) and wire the connector pin 6 or 7 to the appropri­ate Programmable Output Pin on the DM processor. Then
configure the Programmable Output Pin with the DM pro­cessor control panel. The programmable output will latch
to ground, allowing the LED to light when the associated
event takes place.

Basic Room Combining

A typical application for the RCWPB4 is wiring each of
the its outputs (pins 2 – 5) to programmable inputs on the
DM, and using the button press pulses to recall presets
such as those used for room combining. Each button
would correspond to a specific room setup, and the LEDs
would indicate the current room combination.

Triggering Macros and
Indicating DM Processor Events

Another application consists of wiring the RCWPB4’s
outputs (pins 2 – 5) to programmable inputs on a DM pro­cessor to launch macros, but allowing the DM to control
LED’s 1 & 3 in response to certain events. Both EXT 1
& EXT 2 jumpers should be removed and connector pins
6 & 7 wired to DM’s programmable outputs as described
above.
