Gilderfluke&Co 'Smart' Brick Animation Control System - Manual (Page 152)

The only indicator on the MiniBrain is the Heartbeat LED that
shows that it is alive. It flashes at twice the normal rate when run-
ning a show. A Heads Up Display can be used if you need to see
to see the location in the show. This will display the current time
into the show.
There are four opto-isolated inputs on each MiniBrain. Any
input can be triggered by applying a DC voltage between
twelve and twenty-four volts to these screw terminals. The first
three of these inputs are dedicated for starting, stopping, and re-
setting the MiniBrain. The fourth input can be used for either
clocking the MiniBrain externally or selecting between two shows.
The dipswitches determine the function of this input.
The inputs can be used in various combinations. If you want
to always start the show from the beginning, you can wire the
Start and Reset inputs in parallel. In this way the MiniBrain will al-
ways start at the beginning. If you want the MiniBrain to reset
when a show is stopped, then you wire the Stop and Reset inputs
together.
If you need to stop or reset a show at a time before the end of
the memory is reached, then you can program one or more dig-
ital bits on a Smart Brick and feed these output(s) into the appro-
priate MiniBrain input(s). In this way you can divide the memory
into as many small ‘sub-shows’ as you wish, or you can set a
loop point at at any point in the memory. If dividing the memory
into multiple shows, the shows are accessed sequentially. When
one show plays it ends at the start of the memory used by the
next show. The MiniBrain then sits and waits for the next Start input
before playing the next show. Note that the Smart Brick used to
feed bits into the MiniBrain must not be configured to disable its
outputs when stopped. The bit which stopped and/or reset the
MiniBrain will go active again as soon as the next show is started
and immediately re-stop/reset the MiniBrain.
If the inputs are to be enabled or disabled at different times
