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.
The REWIND string is the most complex one when operating a LaserDisk or CD player. This is because
this is the string which is used to spin up and locate the disk to the start of all of the shows. An example of
a typical REWIND string would be:
SA 12345 SE <CR> (R) (<CR>) end-o-string
Translated into HEX ASCII, this string becomes (this is what you would enter):
53 41 31 32 33 34 35 53 45 0D D2 8D 00
The ‘SA’ in this string is the ‘spin up’ command for a Pioneer LaserDisk player. This is followed by a five
digit frame number to search for, and the search command ‘SE’. The rest of the string consists of a <CR>
that tells the LaserDisk player to start working on these commands, and acknowledgment that the LaserDisk
will return at the end of the successful completion of the commands.
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:
PL 1KP <CR> (R) (<CR>) end-o-string
Translated into HEX ASCII, this string becomes (this is what you would enter):
50 4C 30 4B 4C 0D D2 8D 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 before 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 aren’t following the current command with any
other command. The <carriage return> tells the LaserDisk player to start working on all of the commands
it has received since the last <carriage return> was received.
