- Brick Brain Connections -
There are 8 connections which can be made to the Smart Brick Brain. These are:
1) Power: This is a small 12 VDC wall mounted transformer which just needs to be plugged in to
117 VAC.
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
2) SMPTE Input: This is a female RCA jack which should be attached to the source of SMPTE time
code being used (if any). This input has a 10 Kohm input impedance, and expects to see a
SMPTE signal level of about 0 VU.
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
3) Tape Deck Control: This input is normally used to control any tape decks attached to the Brick
Brain. The connections are as follows:
1) Ground
2) +5 VDC
3) Foil A: This is a non-optoisolated 5 volt logic level version of the BLUE input on the J-8
input. There is a 4.7 Kohm pullup resistor to 5 VDC on this input.
4) Foil B: This is a non-optoisolated 5 volt logic level version of the GREEN input on the J-8
input. There is a 4.7 Kohm pullup resistor to 5 VDC on this input.
5 & 6) Rewind Output: These are the relay outputs which close when a ÔRewindÕ command
is encountered in a string being sent at the start or end of any show.
7 & 8) Play Output: These are the relay outputs which close when a ÔPlayÕ command is en-
countered in a string being sent at the start or end of any show.
9 & 10) Stop Output: These are the relay outputs which close when a ÔSTOPÕ command is
encountered in a string being sent at the start or end of any show.

4) 1/4 J-6 input: This is a standard optically isolated 1/4 J-6 input which can be used to randomly
access shows in the Smart Brick System. This input can be configured to operate in one of two
ways. The first of these is a Ôone-of-eightÕ, in which each of the inputs can be used to select
any of the first eight shows in the system (bit 0 selects show #1, bit 1 selects show #2, etc.).
The second operation mode is used when you need to randomly access more than the first
eight shows. In this mode you send the port a binary number to select any of the 63 possible
shows stored in the system. The pin out for the 1/4 J-6 is as follows:
+
PIN #1
PIN #2
PIN #3
PIN #4
PIN #5
PIN #6
PIN #7
PIN #8
PIN #9
