RS-232C port specifications
PC Control of the TV
•
When a programm 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 a 9 pin D-sub/MINI-DIN (optional: AN-A1RS) for the
connections.
NOTE
•
This operation system should be used by a person who is
accustomed to using PCs.
