Connecting a PC

PC control of the TV

When a programme is set, the TV can be controlled from the PC using the RS-232C or IP. 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.

Use an RS-232C serial control cable (cross type), ETHERNET cable (commercially available) or wireless LAN USB adapter for the connections.

NOTE

This PC control should be used by a person who is accustomed to using PCs.
