Gilderfluke&Co DMX-512 Output MultiShow Brick - Manual (Page 7)

On the Front of the BR-MultiShow Bricks:
A) RS-422 Serial Port: This is used to configure the BR-MultiShow Bricks. It is compatible with all
the RS-422 Serial Ports used on Gilderfluke & Company products. This serial port connection is
also connected to the backplane of the BR-MultiShow.
The serial data signals from the BR-MultiShow Bricks are brought out on a six position RJ-11
(modular telephone style connector). Facing the end of the cable with the release latch up-
wards, its pin out is as follows:
COLOR SIGNAL NAME:
LEFT #1 white Signal Ground
#2 black - Serial data out from card
#3 red + Serial data out from card
#4 green - Serial data in to card
#5 yellow + Serial data in to card
RIGHT #6 blue Signal Ground
PC and Compatible Connections: To cross wire the RS-422 / RS-485 signals from the BR-
MultiShow Bricks to the RS-232 serial port of an IBM compatible, cross connect the signals as
follows:
DB-25 DE-9 Signal Signal from/to BR-MultiShow Bricks
2 3 DATA OUT - Serial data into card (#4 green)
3 2 DATA IN - Serial data out from card (#2 black)
7 5 GROUND Signal Ground (#1 white or #6 blue)
Apple Macintosh Connections: Apple Macintosh computers have true RS-422 serial ports
built in. To connect to the BR-MultiShow Bricks, the pin out is as follows (view is of male con-
nector facing the end of the cable):
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 BR-MultiShow Bricks expect to see the serial data in the following format:
ONE START BIT
EIGHT DATA BITS
ONE STOP BIT
The BR-MultiShow Bricks respond only to the commands to enter the configuration mode,
download/upload configuration and status enquiries. It will ignore all other commands. This al-
lows it to share the same RS-422 serial line with additional BS-ANAs, Digital Audio Repeaters,
Smart Brick Brains and other serially controlled devices. The only requirement is that each unit
be addressed to a different location.
B) Board Error LED: This LED will flash when:
1) BR-MultiShow Brick just booted
2) An error is found in the DMX-512 data checksum (if receiving DMX-512 data). If this
and the DMX-512 LEDs donÕt turn off, then you are probably sending a DMX-512
stream to the card that doesnÕt have a checksum in it.
C) DMX-512 LED: This LED will be lit when the BR-MultiShow Bricks is receiving DMX-512 data.
D) Ease In/Brick Heart: This LED will flash at 15 Hz when one or more analogs are performing an
Ease-In.
E) Heartbeat: This LED Flashes continuously while the CPU is running. If it ever stops for more than
a fraction of a second, the 'Deadman' circuit in the BR-MultiShow Bricks will automatically reset
