Gilderfluke&Co 'Smart' Brick Animation Control System User Manual

Notice that after the LaserSearch command we have to then
tell the LaserDisk to start playing, and that we tell the Smart Brick
Brain to wait until it gets all of the echoed characters back from
the LaserDisk player so we know that the command has been
accepted. After this we have a ‘00’ to tell the Smart Brick Brain
that it has found the end of the string.
A typical end string for a Panasonic LaserDisk show is:
Lead-in Pause Lead-out (ACK) (Lead-in) (Pause) (Lead-
out) end-o-string
Translated into HEX ASCII, this string becomes (this is what you
would enter):
02h 4Fh 50h 41h 03h 86h 82h CFh D0h C1h 83h 00h
and it would be displayed on the String Setup Menu as:
02 4F 50 41 03 (06) (02) (4F) (50) (41) (03) 00
The format of this string is pretty much like that of the startup
string, except that there is no need to send the LaserSearch string
as was done at the beginning of the show, and the Play com-
mand has been replaced by a Pause command for the
LaserDisk player. This freezes the image to whatever the last
image on the video disk was. Other commands are available for
blanking out the video, ejecting the disk, or a variety of other
things. You can even build up a string which will tell the LaserDisk
player to search for another frame on the disk and freeze or start
playing from that frame. If no command is given to the LaserDisk
player at the end of a LaserDisk show, then the player will contin-
ue playing along until the end of the disk is reached or another
command is received.
