PC Control of the TV• When a programme is set, the TV can be controlled
from the PC using the RS-232C terminal.
The input signal (PC/video) can be selected, the
volume can be adjusted and various other adjustments
and settings can be made, enabling automatic
programmed playing.
• Attach an RS-232C cable cross-type (commercially
available) to the Din/D-sub RS-232C for the
connections.
NOTE
• This operation system should be used by a person who is
accustomed to using PCs.
