Gilderfluke&Co DMX-512, Serial, and MIDI Output Smart Bricks - Manual (Page 9)

On the Front of the BS-DMX-Tx or BS-Serial Smart Bricks:
A) RS-422 Serial Port: This is used to configure the BS-DMX-Tx or BS-Serial Smart Bricks. It is com-
patible with all of the RS-422 Serial Ports used on Gilderfluke & Company products.
The serial data signals from the BS-DMX-Tx or BS-Serial Smart Bricks are brought out on a six
position RJ-11 (modular telephone style connector). Facing the end of the cable with the re-
lease latch upwards, 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 Ground to force into configuration
PC and Compatible Connections: To cross wire the RS-422 / RS-485 signals from the BS-
DMX-Tx or BS-Serial Smart 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 BS-DMX-Tx/BS-Serial 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 BS-DMX-Tx or BS-Serial Smart Bricks, the pin out is as follows (view is of
male connector facing the end of the cable):
The BS-DMX-Tx or BS-Serial Smart Bricks expect to see the serial data in the following format:
ONE START BIT
EIGHT DATA BITS
ONE STOP BIT
Unlike many of the products manufactured by Gilderfluke & Company, the BS-DMX-Tx or
BS-Serial Smart Bricks will enter configuration immediately upon when the sixth wire is ground-
ed. The serial port connection on the front of the BS-DMX-Tx or BS-Serial are not connected to
the standard serial port buss used on the backplanes by BS-ANA, BS-BRN and other Gilderfluke
Cards. Configuration is always done at 9600 baud, no parity, 8 bits, one stop bit.
B) Board Error LED: This LED will flash when:
1) BS-DMX-Tx or BS-Serial Smart 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.
3) An error is found in the Smart Brick Network checksum (if receiving Smart Brick Network
data)
C) DMX-512 LED: This LED will be lit when the BS-DMX-Tx or BS-Serial Smart Bricks is receiving DMX-
512 data.
D) Brick Heart: The heartbeat from the Smart Brick Brain is transmitted throughout the system
over the Smart Brick Network. The presence of a healthy heartbeat means that the data on
the Smart Brick Network is getting through cleanly. If it ever stutters or flashes erratically (or not
at all), then there is a problem with the Smart Brick Brain, the Smart Brick Network, or the BS-
DMX-Tx or BS-Serial Smart Bricks. As the DMX-512 takes precedence over the Smart Brick
Network, this LED will go dark whenever a DMX-512 signal is present.
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 BS-DMX-Tx or BS-Serial Smart Bricks will au-
