- Rack Smart Brick Brain Connections -
The only connection on the front is the the RS-422 serial port, which is also wired to the backplane.
This serial port is used to send commands to the Smart Brick System or to connect LaserDisk players to
the Rack Smart Brick Brain. It must be connected to a terminal or computer running a modem or termi-
nal emulation program for configuring the Rack Smart Brick Brain. This is the same style of connector and
pin out as is used on the AB-100 Digital Audio Repeaters, and can be attached to both Brick Brains and
Digital Audio Repeaters simultaneously, just so long as their addresses donÕt conflict. Facing the end of
the cable with the release latch upwards, its pin out is as follows:
pin # COLOR SIGNAL NAME:
(left) 1 WHITE signal ground
2 BLACK - serial data out from Brick Brains
3 RED + serial data out from Brick Brains
4 GREEN - serial data in to Brick Brains
5 YELLOW + serial data in to Brick Brains
(right) 6 BLUE signal ground
To cross wire the RS-422 / RS-485 signals from the Rack Smart Brick Brain to the RS-232 serial port of
an IBM compatible or Pioneer LaserDisk player, cross connect the signals as follows:
IBM IBM Pioneer LaserDisk
DB-25 DE-9 DB-15 SIGNAL SIGNAL FROM/TO BRICK BRAIN
2 3 2 DATA OUT - serial data in to Brick Brain (GREEN)
3 2 3 DATA IN - serial data out from Brick Brain (BLACK)
7 5 1, 11 or 15 GROUND signal ground (BLUE or WHITE)
Apple Macintosh computers have true RS-422 serial ports built in. To connect to the Smart Brick
System, the pin out is as follows for a Macintosh mini-DIN-8:
to + serial data in to card (#5 yellow)
to - serial data in to card (#4 green)
1 2
3 4 5
6 7 8
from - serial data out from card (#2 black)
from + serial data out from card (#3 red)
signal ground (#1 blue or #6 white)
The Rack Smart Brick Brain can sequentially control up to seven LaserDisk Players using the LaserDisk
multiplexer (BS-LDMUX15 for Pioneer/Panasonic players or BS-LDMUX25 for Sony). This attaches to the
Rack Smart Brick Brain through its relay outputs and RS-422 serial port as shown in the following drawing.
The BS-LDMUX also converts the RS-422 ports on the Rack Smart Brick Brain to the RS-232 needed by the
LaserDisk players. Indicator LEDs show serial data being sent to and received from the different
LaserDisks. The serial ports on the LaserDisk Multiplexer are at RS-232 levels. Standard 15 (Pioneer or
Panasonic) or 25 pin (Sony) cables can be used to attach the LaserDisks to it. A Ê small 12 VAC power
supply runs the LaserDisk Multiplexer. The Rack Smart Brick BrainÕs relay outputs can not be used for any
other purpose when running multiple LaserDisk players.
The majority of Backplane Connections are typically made through the 40 pin IDS connector on a
Brick card cage:
