01 50 4C 0D (52) (0D) 00
Notice that after the LaserSearch command we have to then tell the LaserDisk to start playing, and
that this command is followed by one <carriage return> character to be sent out. Following this we tell
the Brick Brain to wait until it gets first an ÔRÕ, and then a <CR> back from the LaserDisk player. After this
we have a Ф00Х to tell the Brick Brain that it has found the end of the string.
A typical end string for a LaserDisk show is:
ST <CR> (R) (<CR>) end-o-string
Translated into HEX ASCII, this string becomes (this is what you would enter):
53 54 0D D2 8D 00
and it would be displayed on the String Setup Menu as:
53 54 0D (52) (0D) 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send the LaserSearch string as was done at the beginning of the show, and the PL command has been
replaced by a ST (still frame) command for the LaserDisk player.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 continue playing along until
the end of the disk is reached or another command is received.
As an example of how you combine more than a single LaserDisk command in the same string, we
will now show a sample of a string which sends two commands at the same time to the LaserDisk player.
A typical combined start string for a LaserDisk show is:
LaserSearch PL 1KP <CR> (R) (<CR>) end-o-string
Translated into HEX ASCII, this string becomes (this is what you would enter):
01 50 4C 30 4B 4C 0D D2 8D 00
and it would be displayed on the String Setup Menu as:
01 50 4C 30 4B 4C 0D (52) (0D) 00
This string is just like the start string shown above, except that it sends a command to disable the
front panel keypad on the LaserDisk player after it sends the command to start the show playing, but be-
fore it sends the <carriage return> that tells the LaserDisk player to start acting upon all the commands
it has just received.
The following is a partial listing of the commands supported by Pioneer LaserDisk players. It is by no
means a complete list of all of the commands available to you, but includes those common commands
which you may actually need. Remember that you only need to send the <carriage return> (0D)
(shown as the last character of all the commands) only if you arenÕt following the current command with
any other command. The <carriage return> tells the LaserDisk player to start working on all of the com-
mands it has received since the last <carriage return> was received.
