Gilderfluke&Co BR-MultiBrick32 - Manual (Page 13)

BR-MultiBrick32 Connections
RS-422 Serial Port (Revision 1.nn Cards Only): This is used to config-
ure the BR-MultiBrick32. It is compatible with all of the RS-422 Seri-
al Ports used on Gilderfluke & Company products.
As a convenience, the four active lines on this connector are
bussed to the backplane of the card cage. This allows you to
communicate to a whole card cage full of BR-MultiBrick32, BS-
ANAs, 'Smart' Brick Brains, Electronic FeedBack (EFB) 'Smart' Bricks
and other cards through the connector on any single card. They
just need to be set to different addresses. If desired, permanent
connections can be made on the back of a card cage.
Revision 2.00 and later BR-MultiBrick32 cards have only the
backplane serial port connections.
The serial data signals from the 1.nn revision BR-MultiBrick32s
are brought out on a six position RJ-12 (six position, six conductor
modular telephone style connector). Facing the end of the cable
with the release 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 Signal Ground
PC and Compatible Connections: If you are only talking to a
single BR-MultiBrick32 and your wire length is short, you may be
able to simply cross wire the RS-232 serial port on your PC to talk
to the BR-MultiBrick32. This does not work on all PCs, as some
don’t swing their RS-232 outputs as far as they should. If it does
not work with your PC, you may need to get a RS-232 to RS-422
converter (like our 232conv-09) to talk to the BR-MultiBrick32. To
cross wire the RS-422 / RS-485 signals from the BR-MultiBrick32 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-MultiBrick32
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)
