CHAPTER 3: Configuring the ACS235A

3. Configuring the ACS235A

This chapter describes how to configure the PC model of the ServSwitch™ Brand Fiber KVM Extender (ACS235A). If your Extender is the Sun model (ACS236A), see Chapter 4.

3.1 Configuring for RGB Video

In normal configuration at delivery time, the Extender units are configured to carry video from a VGA source to a VGA monitor. But if you’d like to attach RGB equipment (either an RGB source or an RGB monitor or both) to your Extender system, this section discusses how you might need to set the units’ configuration jumpers. (See Table 3-1 on page 15 for a full layout of this.) Of course, RGB video can come in a variety of signal forms and combinations. If after reading the rest of this section you’re not sure how to get your RGB application working (or even whether it can be done), call Black Box for technical support.

NOTE

In any application involving RGB video, if the picture on your monitor looks OK with AGC ON, leave the Local Module’s JP3 jumper and the Remote Module’s JP8 jumpers in their factory settings. Otherwise, remove JP3 at the Local Module and move JP8 at the Remote Module to turn AGC OFF. You will then have to adjust the gain of the Extenders’ video signal manually. See Sections 3.2.3 and 3.3.2.

3.1.1VGA VS. RGB SIGNALING

VGA uses two video-synchronization signals, HSYNC (horizontal sync) and VSYNC (vertical sync). In its factory-default settings, the Extender’s Local Module receives these signals from the CPU and overlays them on the color signals for transmission to the Remote Module: HSYNC on green, VSYNC on blue, and SYNCPOL (the combined HSYNC and VSYNC polarity information) on red. But most RGB applications use a single CSYNC (composite sync) signal overlaid on the green color signal instead, so for such applications you’ll need to have the Local Module substitute this signal for HSYNC, as well as create its own SYNCPOL information for use by the Remote Module. Then you might have to set the Remote Module to process these signals properly at the other end.

3.1.2VGA VIDEO CARD TO RGB MONITOR (VGA TO RGB CONVERSION)

To connect a CPU that outputs VGA video to an RGB monitor, remove the Local Module’s JP2 jumper (so that it generates the CSYNC signal needed by the RGB monitor), but leave the JP6, JP10, and JP11 jumpers in their factory-default settings (see Sections 3.2.1 and 3.2.2). At the Remote Module, install jumpers at
