Gilderfluke&Co BR-MultiBrick32 - Manual (Page 11)

a) When operating as a 'Smart' Brick: This LED will display the
'Smart' Brick Brain’s heartbeat. This is transmitted from the 'S-
mart' Brick Brain through the 'Smart' Brick Network that inter-
connects all of the 'Smart' Bricks. If this LED is not flashing,
then you need to check your 'Smart' Brick Network connec-
tions or your 'Smart' Brick Brain.
b) When operating as a 'Dumb' Brick: This LED will be ON
whenever a show is running. It will be off when no shows are
running. This output is also sent out the ‘Yellow’ status output
on the ‘J8’ connection on the backplane.
c) When receiving data download for permanent storage in
Flash memory (Revision 1.nn Cards Only): This LED will
flash to show that data is being received.
3) DMX-512: This LED will light to show you that the BR-MultiBrick32 is
receiving realtime updates through either the DMX-512 or RS-422
serial ports.
4) Board Error: This LED will flash to show you that the BR-MultiBrick32
has sensed one of the following errors:
a) Just booted: Lights for a short period each time the BR-
MultiBrick32’s microcontroller starts up.
b) 'Smart' Brick Network Error: Flashes if an error is received
in a 'Smart' Brick Network packet from the 'Smart' Brick Brain.
c) Realtime DMX-512 Update Error: The optional checksum in
the DMX-512 realtime update didn’t agree with the data re-
ceived.
d) Realtime Serial Update Error: The checksum in the RS-422
serial port realtime update didn’t agree with the data re-
ceived.
e) Download Error: There was an error in the data being
downloaded to the BR-MultiBrick32.
f) Download Timeout: If the data being downloaded to the
BR-MultiBrick32 stops mid-stream, this LED will flash as the BR-
MultiBrick32 returns itself to normal operating mode.
g) Data Verification Failure: If you ask the BR-MultiBrick32 to
verify the data in its flash memory, and it finds an error, it
will flash this LED as well as displaying an error message on
your computer screen.
h) Memory locked: If you try to clear the flash memory or
