1. Connect the DMX-512 shield to the Br-miniBrick8 power supply ʻgroundʼ. This sig-
nal is normally found on pin #1 of a standard DMX-512 XLR-5 connector.
2. Connect the DMX-512 negative data to the DMX-512 ʻ-ʼ input. This signal is normally
found on pin #2 of a standard DMX-512 XLR-5 connector.
3. Connect the DMX-512 positive data to the DMX-512 ʻ+ʼ input. This signal is normally
found on pin #3 of a standard DMX-512 XLR-5 connector.
The Br-miniBrick8 uses a maximum of three data channels from the DMX-512. The
first channel is used for the eight digital outputs. The next consecutive DMX-512 chan-
nel is used for the first ServoMotor output. The next consecutive output is used for the
second ServoMotor output. The base address used for the DMX-512 and serial Real-
Time data is set using the configuration menu, or by sending an AutoDownload file to
the Br-miniBrick8 with the desired base address offset.
When receiving DMX-512 data, the Br-miniBrick8 no longer needs the two trigger
inputs or their indicator LEDs. They are used as follows:
a. The ʻAʼ inputʼs LED is borrowed to toggle on each frame received. If receiving
DMX-512 data at 30 FPS, the LED will be flashing at 15 Hz.
b. The ʻBʼ inputʼs LED is borrowed to flash each time there is an error in the re-
ceived DMX-512 or Serial RealTime data. If you see this flashing any more
than occasionally, check your DMX-512 wiring. You may need to terminate
the DMX-512 data lines with a 120Ω resistor.
If the Br-MiniBrick8 receives a DMX-512 signal on this input, or even spurious noise
that sounds to it a lot like DMX-512, it will stop running any animation sequence and
stop to listen for valid DMX-512 data. If no DMX-512 is received, then the animation se-
quence can be restarted by whatever means it has been configured to use (trigger or
power-up).
ʻAʼ & ʻBʼ Trigger Inputs:
The trigger inputs can be used to start, stop, pause or
select specific show sequences to play from any switch.
This can be a pushbutton, motion detector, IR beam, step
mat, or anything else that will give you a ʻswitch closureʼ.
The trigger input is non-polarized and optoisolated. You
must feed a voltage in to trigger it. You can ʻborrowʼ power
that is running the Br-MiniBrick8. The green LED lights
when a trigger input is active.
Any event can be triggered on either the
ʻclosingʼ or ʻopeningʼ edge of either input. A
ʻclosingʼ is when you apply a voltage to an in-
put. An ʻopeningʼ is when that voltage is re-
moved. The inputs can be triggered on any
voltage from 9 to 24 VDC. If you donʼt have an
