Gilderfluke&Co old Smart Brick Manual - Manual (Page 127)

The decimal points on the ÔMinutes/Seconds/FramesÕ display are used to show a variety of conditions
in the Smart Brick System:
Data Error: This light will flash when the Heads Up Display receives a bad packet of data from the
Smart Brick Brain. You should almost never see this one flash. If you do, it means that there is
something wrong with the connection between the Smart Brick Brain and the Heads Up
Display, and by implication, that the data getting to the Smart Bricks is also suspect.
Display Update: This flashes every time the Smart Brick Brain updates the entire system. If it is not
flashing, then there is definitely something wrong with the connection between the Smart
Brick Brain and the Heads Up Display, and by implication, that the data getting to the Smart
Bricks is also suspect.
Heartbeat: This should flash in exact synchronization with the ÔHeartÕ on the front of the Smart Brick
Brain. If it doesnÕt, or if it flashes irregularly, then there is probably something wrong with the
connection between the Smart Brick Brain and the Heads Up Display, and by implication, that
the data getting to the Smart Bricks is also suspect.
Advancing Frames: This is lit whenever the Smart Brick System is advancing frames. If any of the
Smart Bricks in the system are configured to Ôdisable the outputs when stoppedÕ, they will only
have their outputs enabled when this LED is lit. The number of ÔheartbeatsÕ that this LED will
stay on after the system stops running a show can be set when configuring the Smart Brick
Brain to anywhere from 1 to 256 beats.
Global Record: This LED is lit only when Dipswitch #6 in the Brick Brain is ÔONÕ to enable recording
on the Smart Bricks and the system is advancing frames. When this LED is off, it shows you that
the reason the record LEDs on the Smart Bricks wonÕt turn on is that you havenÕt enabled them
in the Brick Brain.
Time Code Error: This LED will flash whenever the Brick Brain is correcting an error in the incoming
time code. If it flashes too often, then there is a problem with the connection to the SMPTE
source, or the level of the SMPTE getting to the Brick Brain is either too high or too low.
Occasional errors in SMPTE time code arenÕt all that unusual, so donÕt be alarmed it this LED
flashes occasionally. This indicates that the Brick Brain is doing itÕs job, and has detected and
corrected an error. Generally these errors represent a glitch in the time code as it is recorded
on the tape (or whatever medium is being used as the source for the SMPTE time code), and
so will occur at the exact same instant in the show every time it is played.
