CHAPTER 3: Configuring the ACS235A

3.2.1 THE VGA/RGB JUMPERS (JP6, JP10, AND JP11)

If you’ll be using a VGA monitor in your Extender system, leave these jumpers set as they are (in their factory-default positions). But if you need to use an RGB monitor instead, take these steps (refer to Figure 3-2):

•Install a jumper on JP6 if you want the Extender to add the HSYNC (horizontal sync) polarity signal to the red color signal.

•Install a jumper on JP10 if you want the Extender to add the VSYNC (vertical sync) polarity signal to the red color signal.

•JP11 is the main VGA vs. RGB control. To select RGB on the local side (if your computer is transmitting RGB video), move the jumper from the left-hand posts to the right-hand posts, as shown below.
