ÒkÓ Select from J6:
If more than one show is stored on a single Smart Brick System, each one can be accessed individu-
ally and played back. Up to 255 of these shows can be stored on a single Smart Brick System. These re-
quests can be made through the serial port or through the 1/4 J6 Port.
This toggle enables the 1/4 J6 Port for requesting the shows on this Smart Brick System. There are two
methods of selecting shows from this port. Which one is used is selected by the DIRECT SELECT com-
mand.

ÒlÓ Direct Select:
This command is used to switch the 1/4 J6 Port over to selecting 1 of 8 shows directly, instead of
using binary inputs for requesting up to 255 different shows. The DIRECT SELECT is useful when you have
eight or less shows which need to be called up through the 1/4 J6 Port. The 1/4 J6 Port can be wired di-
rectly to up to eight different pushbuttons. When any of these buttons are pressed it will select the ap-
propriate show. The first button pushed will be played at the next START or START LOOPING command,
unless it is overridden by another show request from the serial ports. (The Brain can also be told to start
playing the newly requested show immediately if you tell the Brick Brain to START or START LOOPING on
the input to the 1/4 J-6 port.)
If this mode is off, then up to 255 different shows can be selected through the 1/4 J6 Port. The 1/4
J6 Port can be connected directly to the output of a computer or Animation Control System. If you need
to connect it to pushbuttons, you will need to use diodes or a keyboard with an encoder (available from
Gilderfluke & Company) to encode a binary number to be sent to the 1/4 J6 Port.
As with changes in inputs on the A, B, or PB input, changes on the 1/4 J6 Port can be used to START,
stop, or whatever a Brick Brain. If the DIRECT SELECT option is 'on', then a rising edge is on any new ar-
rival of a new closure, and a falling edge is when all input lines are opened. If the DIRECT SELECTION is
'off', then a rising edge is on any change in the 1/4 J6 Port except for when all of the inputs go open,
which is considered to be a falling edge.

ÒnÓ Debounce:
This command is used to set the number of times the software in the Brick Brain will check the Blue,
Green or 1/4 J6 inputs before actually believing them. Valid entries are from 0 to 255 (00H to FFH). A
zero entry gives a 256 count loop for the longest possible response, 01 gives the fastest possible respon-
se. Too small of an entry for the DEBOUNCE can cause problems with the inputs if they are noisy or tend
to bounce. Too large a value will cause a delay before the Brick Brain responds to these inputs. The de-
fault value is eight.

ÒpÓ Running Delay:
The running delay is the number of heartbeats after which the Smart Bricks stop advancing frames
until it turns off the ÔAdvancing FramesÕ LED on the Heads Up Display and disables any Smart Brick outputs
which have been configured to be Ôdisabled when stoppedÕ.
