User Manual

General error and status conditions are displayed in the ÔHoursÕ display in the front of the Heads Up
Display. The meanings of these Error Messages are as follows:
E1: Brick Overflow: This indicates that the frame number requested is beyond the end of the
memory installed in the Smart Bricks attached to the system. Dipswitch number 5 must have
been set to tell the Brick Brain how big the Smart Bricks are for this function to work properly.
E2: SMPTE Time Code Error: This is displayed when the Brick Brain has started listening for a SMPTE
time code, and the ÔSMPTE HourÕ byte of the incoming time code identified a show which
wasnÕt a SMPTE time code show.
E3: End Of Show: This is not really an error condition, it just shows that the end of the show being
played has been found
E4: String Error: This error condition is displayed when the string being sent requested a specific
ASCII character to be returned by whatever is connected to the serial port, and a different
character was returned.
E5: Invalid Frame Rate: This error condition is displayed when the frame rate set in the system is
not valid for the time code of the show which is being started. An example of this would be if
the frame rate were set to 16 frames per second and a SMPTE time code is being used. As this
is not a valid frame rate for a SMPTE show, an ÔE5Õ would be displayed.
E6: LaserStart Error: This is displayed when an attempt is made to start a LaserDisk show by send-
ing it a Ôsearch for frame number commandÕ. After a number of tries (which can be set from 1
to 256 in the configuration of the Brick Brain), the Brick Brain will then try to start up the
LaserDisk player (see ÔF2Õ below).
E7: LaserLoop Error: This is displayed when an error is made in the response received from a
LaserDisk player while it is running a LaserDisk show.
E8: Start Error: The only time this error is displayed is when the time code is asking for a show
frame number which is actually before the first frame of the show being played. About the
only way of getting the system into this condition is to use the manual controls on the front of
the LaserDisk player to manually ÔrewindÕ the show to a frame number before the start of the
show.
E9: Response Error: This error is displayed when a string being sent at the start or end of a show
has requested a character to be returned by whatever is attached to the serial port, and
nothing has been returned within about 45 seconds. About the only time you will see this error
is when the LaserDisk player is actually turned off when an attempt is made to start a LaserDisk
clocked show.
EA: Call Home: If this error message ever appears in the ÔhourÕ display, you should call the vendor
who installed your show.
F1: Sending String: This code indicates that a string is being sent at the start or end of a show.
When this code is displayed, the ÔMinutesÕ will be showing the string number being sent out,
the ÔSecondsÕ showing the entry number in the string which is being sent out, and the ÔFramesÕ
showing what the entry is which is being sent. Normally this flashes by so fast that you canÕt
read it, but is useful when there is a holdup of some sort in the string. Typical of these is if the
LaserDisk doesn'tÕ respond to a command as expected, or when you have put an entry in the
string which causes the Brick Brain to wait for a switch closure to come in on one of itÕs inputs.
F2: Starting LaserDisk: After the Brick Brain has tried telling the LaserDisk player to search for the
starting frame of the show for the number of times set in the configuration (an ÔE6Õ is displayed
while it is doing this), the Brick Brain will send a Ôstart-upÕ sequence of commands to try to tell
the LaserDisk player to close the door and spin up the disk.
