Position 'A' allows all shows to run as per their
schedules.
While interactive is active, any show not associated
with a trigger will run as scheduled, these may be
interrupted by shows 1-6 being triggered.
Triggered shows do not follow scheduled times.
They run when triggered. A triggered show does
follow the rules for run once or run continuously. If
you set a triggered show to run continuously, then
you will not be able to stop it without resetting the
DC-MP3 once it has been triggered.
Position 'F' is used to manually set the clock. See
the section Setting the DC-MP3's Clock.
Positions '0,' 'B, ' 'C,' 'D' and 'E' are not currently
used and are treated the same as position 'A.'
Interactive Inputs
The 'INPUTS' header at the top center of the circuit
board can be used to trigger shows with momentary
contact switches or motion detectors. Both +10 volts
DC and +5 volts DC are provided at this connector
to power external sensors (like motion detectors.)
The following diagram shows the input header pin
assignments:

To use these pins to trigger show(s), the selector
switch must be set to 'B.' See the Selector Switch
section for more information on how triggered shows
behave.
The input pins ('1' through '6') are pulled to +5v with
a on-board resistor. One or more of these input pins
is connected to the GRND pin through your trigger
switches.
These inputs can be configured by the Hardware
Utility for normally open switches (NO,) meaning that
the switch closes the circuit when activated or
normally closed switches (NC,) meaning the switch
opens the circuit when activated. Most motion
detectors contain NC switches.
Pin 'A' is for future use and should not be connected
to anything.
RJ45 Network Connections
Use either of these connectors to connect to your
controllers and/or a Windows PC through an RS485
adapter.
