Pioneer LaserDisk/DVD DB-15 Female

The ground connections to pins #11 and #15 may need to be disconnected when

used with Pioneer DVD players. The usage of these pins are different from those of their
LaserDisk counterparts.

In general, you send a command to a Pioneer LaserDisk/DVD player as two ASCII

characters (with occasional variables), followed by a character (0Dh).
The LaserDisk/DVD player will then respond when it has completed the task with an up-
per case ʻRʼ followed by a character (0Dh). A number of different
commands can be stacked together and then followed by a single
character (0Dh) to get them all rolling. The LaserDisk/DVD player will go through all of
these commands in the order they were entered and then return an ʻRʼ followed by a
character (0Dh) when it has finished the last command. This can save
a lot of string space if you are sending complicated strings to the LaserDisk/DVD player.

The majority of commands which you might need to use are all pretty simple two or

three character ones. The one complicated ʻsearchʼ command is handled transparently
to you when you insert a LaserSearch character in the string being sent to the
LaserDisk/DVD player (the Br-SDC must first be told it is running a Pioneer player). This
string only performs a search for the starting frame of the show on the LaserDisk/DVD
player. For this reason it is normally followed by a ʻPLʼ (play) command in the same
string.

A typical start string for a LaserDisk/DVD show is:

!

LaserSearch ʻPʼ ʻLʼ (ʻRʼ) () end-o-string

Translated into HEX ASCII, this string would be displayed on the String Setup Menu

as:

!

serch 50h 4Ch 0Dh (52h) (0Dh)

Notice that after the LaserSearch command we have to then tell the LaserDisk/DVD

to start playing, and that this command is followed by one character to
