Т9У Countdown End:
Each Rack Smart Brick Brain has two opto-isolated external inputs, one push button input on the
front, and one 1/4 J6 Port input (8 optoisolated inputs). Additionally, the Brick Brain treats the end of a
countdown just like it would treat any of the other inputs. These commands are used to select what ac-
tions will take place on each edge of each of these inputs. Note that both rising and falling edge actions
are available to you. This allows you to to do things like start a show on a closing edge and then stop it
on the opening edge of the same input. This would make it into a Ôrun whileÕ input.
The closing edge on the 'GREEN', 'BLUE, and 'PB' inputs are considered to be when a normally open
push button or switch is closed. The opening edge is when that same switch or push button is opened. A
closing edge on the 1/4 J6 Port is considered to be any of the eight inputs closing if the DIRECT SELECT
option is 'on', or any change in the input (except going to all inputs open) if the DIRECT SELECT option is
off. A opening edge on the 1/4 J6 Port is when all eight of the inputs go to an open condition.
The hardware for the 'GREEN', and 'BLUE', inputs need an external power source for the opto isolators
to run. The 1/4 J-6 input can be jumpered on the Rack Smart Brick Card to use an external power supply
or the internal power supply. Connections for these are shown elsewhere in this manual.
If you want the Smart Brick System to start playing shows as soon as it is powered up, you can set a
ÔSTARTÕ or ÔSTART LOOPINGÕ command on the opening edge of any of the inputs. On power-up, the Brick
Brain will check all of the inputs and find that the one you are using has just opened. It will then act
upon any commands you have set for this edge. This would normally be a ÔSTARTÕ command if you only
want the Smart Brick System to play a single show, or a ÔSTART LOOPINGÕ command if you want it to con-
tinue playing shows until it is told to stop. We normally use the ÔPB openingÕ edge to start shows on power-
up (you can use any of the ÔopeningÕ edges) and then put in a ÔSTOPÕ or ÔSTOP AT ENDÕ command on the
ÔPB closingÕ command so that we can stop the shows once they have started.
If multiple inputs to the system arrive simultaneously, they have the following priorities:
1) '1/4 J6 PortÒ INPUTS
2) 'GREEN' input
3) 'BLUE' INPUT
4) 'PB' INPUT
This will probably happen only on power-up.
The commands have the following effects:
Pause/Return to Zero (RTZ):
a) If running an Internally, Smpte or LaserDisk clocked show: This command causes the
currently running show to be paused at the current frame. If the show is LaserDisk
clocked, the string ÔEÕ will be sent when the show is paused. This string is typically config-
ured to pause the LaserDisk. A pause will be cleared if a new show is started, or the
Continue command is used.
b) If running an Externally clocked show: When running an internally clocked show, this
command causes the frame counters to be reset back to the start of the show. During
countdowns, this command causes a new countdown delay to be started based on the
current thumbwheel switch settings.
Continue/Increment:
a) If running an Internally, Smpte or LaserDisk clocked show: This command clears a
pause in the currently running show which was set by the Pause command. If a show
