Connecting a PC
PC control of the TV
• When a programme is set, the TV can be controlled
from the PC using the RS-232C .
The input signal ( TV/video ) can be selected,
the volume can be adjusted and various other
adjustments and settings can be made, enabling
automatic programmed playing.
• Use an RS-232C cable cross-type (commercially
available), for the connections.
NOTE
• This operation system should be used by a person who is
accustomed to using PCs.
Communication conditions for RS-232C
Set the RS-232C communications settings on the PC
to match the communications conditions of the TV.
The communications settings of the TV are as follows:
Baud rate:
Data length:
Parity bit:
Stop bit:
Flow control:
Communication procedure
Send the control commands from the PC via the RS-
232C connector. The TV operates according to the
received command and sends a response message to
the PC.
Do not send multiple commands at the same time.
Wait until the PC receives the OK response before
sending the next command.
