SERVSWITCH™ BRAND FIBER KVM EXTENDERS

3.3.1THE SYNC-ON-COLOR JUMPERS (JP1, JP2, AND JP3)

The Local Module of the ServSwitch Brand Fiber KVM Extender adds synchronization signals to the color signals for transmission across the fiber link. If you are using a VGA monitor (which is probably not equipped to handle sync on color), you will want the Remote Module to use its decoupling diodes to strip this sync information from the color signals, so you will leave the jumper posts at locations JP1, JP2, and JP3 empty (the default setting) so that these diodes will be active. But if you are using an RGB monitor (which is probably designed to receive sync on color), you will want the Remote Module to leave the sync signals combined with the color signals, so you should install jumpers at JP1, JP2, and JP3 to deactivate the decoupling diodes, as shown in Figure 3-7.

CAUTION!

The on-screen image might be displayed at a different size or screen location at the remote site than it is when the monitor is attached directly to the PC’s CPU. This difference can be fixed or at least minimized by using the monitor’s display-size and -placement controls. Screen images that appear normal except for their size or placement can not be made “right” by installing these jumpers!
