Pioneer DVD-V7200 Industrial DVD Player RS-232C - Manual (Page 41)

Command Descriptions
- 33 -
Format : Integer KL
Explanation : The command enables/disables the remote control, the external switch
including power control functin, mouse and accessing to the front panel buttons. The
default value is 0 (OFF) thus the player is unlocked.
If the key lock switch is set to 1, all buttons (front panel including power and remote
control) external switch control including power control and mouse control are
disabled. Use this setting for a PC-controlled player to lessen interference from
outside sources such as remote control units.
If the key lock switch is set to 2, only the tray open button/key is disabled and the OP
command no longer controls the tray. Thus, after powering off the player, the locked
tray protects the disc from unauthorized personnel.
