    Equipment damage may result. RANSLATION The data translation capability of the S768DAV series is unique in the industry. It enables translation from one data format to another and eliminates the need for external translation devices. The translation is in the physical layer only; it cannot interpret specific protocols or translate commands.

    ATTERN ENERATOR The S768DAV links support both NTSC and PAL video standards without adjustment. DIP switch SW8 on the S768DAVT transmitter and S768DAVR receiver audio/data cards enable the test pattern generator and select the video format. To enable the test pattern generator and set the video format, see Figure 2 and Figure 5 and perform the following.
