The laserdisc player can be controlled mainly
by an external computer with an RS-232C interface. The player are designed to
play Analogue soundtrack Laservision discs only and are not compatible
with NTSC or PAL Laserdiscs and CD Videos with digital PCM soundtracks. If in
doubt look out for discs with a CX noise reduction logo as this is only
used on analogue soundtracks.
|This is an NTSC laser
disc player that was not used in any laser disc games from the factory.
This player can be used as a direct replacement for any of the games that
are listed in the LDP-1450 section, except Dragon's Lair II.
(if you want to use this player in a Dragon's Lair II,
Using the Laser Ace
Conversion Card, this player can be used in many other laser disc games.
For more information on which games it will work with, see the
Laser Ace home page.
The LD player must be set to 9600 baud
rate for proper communication with the PCB. The dip switch settings for
the Sony LDP-2000 are: 1-up, 2-up, 3-up, 4-down. For info on the
Command Set, check the
Sony Command Set
In addition to computer control the
LDP-2000 (and probably others in the series) can be controlled with the optional
RM-2001 remote control unit.
The factory preset data format is as
Due to my lack of programming skills I
simply created batch files which sent the requisite character to the serial
- Asynchronous mode
- 8 bits character length
- 1200 bps baud rate (adjustable via
selector on back of unit between 1200, 2400, 4800, 9600 bps)
- No parity check
- Least significant bit first (1 bit
For example: play.bat ==> echo ":" >com2
