The jumpers perform the following functions:

Negative Follow

Wide Short

5.

J20: Sync polarity jumper — This jumper adjusts the output sync polarity. Horizontal (H) and vertical

(V)sync output can either follow input sync polarity, or be forced to negative.

•If the jumper is placed on pins 1 and 2, output H and V sync polarities will be forced to negative.

•If the jumper is placed on pins 2 and 3, output sync polarity will follow input sync polarity: the output sync signal’s polarity will be the same as the input polarity. This is the default setting.

J40: Vertical sync width jumper — This jumper adjusts the vertical sync pulse width. Some digital display devices have very specific requirements for incoming sync pulse width. If no picture displays, the picture cuts in and out, or the picture is scrambled, try adjusting the vertical sync pulse width or switching from ADSP™ to DDSP™.

•If the jumper is placed on pins 1 and 2, the output vertical sync pulse will be wide.

•If the jumper is placed on pins 2 and 3, the output vertical sync pulse will be short (narrow). This is the default setting.

Replace and fasten the enclosure cover, reversing step 2.
