RS-232C port specifications
PC Control of the TV
When a program 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.
Communication conditions
Set the RS-232C communications settings on the PC to match
the TV’s communications conditions. The TV’s communications
settings are as follows:
RS-232C serial control cable
(cross type, commercially available)
9 pin D-sub/MINI-DIN
conversion cable
(optional: AN-A1RS)
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.
