Analog Video Input:

0.7 V

RGB or YP

(1.0 V

including sync.)

• PROGRESSIVE SCAN DVD Players

• 480i, 480p, 576i, 576p, 720p, 1080i, 1080p/60 video sources

• VGA - UXGA VESA video sources

3 Jumper Instructions

JP1:— SD/HD Selection. (This should be left un-jumpered, when in Auto Mode, which is typically

recommended.)

JP2:— Input Source Select

JP3:— Auto/Manual Mode Select

JP4:— Power Save Mode

JP5:— Horizontal Sync Output Polarity

JP6:— Vertical Sync Output Polarity

• Power save mode is enabled when “HIGH” and disabled when “LOW”

• Auto mode is selected when JP3 is “HIGH”, and manual mode is selected when JP3 is “LOW”

• Input source 1 (PC/VGA) is selected when JP2 is “LOW”, and input source 2 (YP

) is selected when

JP2 is “HIGH”

• IF manual mode is selected, SD (480p) corresponds to JP1 being “LOW” and HD (720p and 1080i)

corresponds to being “HIGH.” IF auto mode is selected, JP1 must be left un-jumpered, and TP14 will

measure “LOW” or “HIGH” depending on whether the input is SD or HD, respectively.
