HOW TO CONTROL TV BY PERSONAL COMPUTER - SHARP LC-32GA8 – LC-32BV8 – LC-37GA8 – LC-37BV8 - LCD TV



PC CONTROL OF 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: A person who is accustomed to using PCs should use this operation system.
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:
  • 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.
