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

Communication procedure
Send the control commands from the PC via the
RS-232C connector.
The TV operates according to the received

Wait until the PC receives the OK response before
sending the next command.
