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.
Communication conditions
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:
9,600 bps
Data length:
8 bits
Parity bit:
None
Stop bit:
1 bit
Flow control:
None
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.
