Gilderfluke&Co 'Smart' Brick Animation Control System - Manual (Page 172)

PC•MACs and the LaserDisk (or DVD) player are long, then you
may want to add a RS-232 to RS-422 converter to the LaserDisk
(or DVD) player.
In general, you send a command to the LaserDisk (or DVD)
player as two ASCII characters (with occasional variables), fol-
lowed by a character (0D). The LaserDisk (or
DVD) player will then respond when it has completed the task
with a upper case ‘R’ followed by a character
(0D). A number of different commands can be stacked together
and then followed by a single character (0D)
to get them all rolling. The LaserDisk (or DVD) player will go
through all of these commands in the order they were entered
and then return a ‘R’ followed by a character
(0D) when it has finished the last command. This can save a lot
of string space if you are sending complicated strings to the
LaserDisk (or DVD) player.
The majority of commands which you might need to use are
all pretty simple two or three character ones. The one complicat-
ed ‘search’ command is handled transparently to you when you
insert a LaserSearch (01) character in the string being sent to the
LaserDisk (or DVD) player (the Smart Brick Brain must be told it is
running a Pioneer player in the configuration screen). This string
only performs a search for the starting frame of the show on the
LaserDisk (or DVD) player. For this reason it is normally followed by
a ‘PL’ (play) command in the same string.
A typical start string for a LaserDisk (or DVD) show is:
LaserSearch PL (R) () end-o-string
Translated into HEX ASCII, this string becomes (this is what you
would enter)
01 50 4C 0D D2 8D 00
and it would be displayed on the String Setup Menu as:
01 50 4C 0D (52) (0D) 00
