24 DR66 & DR128 Installer User Guide
Remote Switch Examples The first shows the DR128 wired to two switches providing a remote
wall plate volume up/down function. The second shows the same wall plate duplicated so that the
volume can be controlled from two or more positions. Simply wire the switches in parallel.
Remote Outputs
The DR66 provides 4 opto-isolated output control lines. None are available on the DR128. These
are typically used to provide remote indication such as active patch, source or channel mute, or to
trigger remote equipment such as room dividers or lighting systems.
The function of these outputs is assigned in a similar way to the front panel soft LEDs using the
WinDR editing software running on a PC. Refer to the Help file provided within WinDR for details.
Functions available include:
• Static indicator (patch change)
• Input or output channel mute
Wiring Remote Outputs Use shielded cable with the output wires protected from interference by
an outer shield. Use a 25-pin male D-type connector. Note that the remote switch inputs and
back-up battery input are also on this connector. Connect its shell to the cable shield. Wire the
output to drive the external indicator, relay or other equipment as shown. Observe the correct
polarity. Ensure the remote equipment does not draw more than 10mA maximum.
