Appendix
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
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.
