SERVSWITCH™ BRAND FIBER KVM EXTENDERS
3.2 Setting the Jumpers in the Local Module (Optional)
There are six user-settable jumpers inside the Local Module of the ServSwitch
Brand Fiber KVM Extender. They control these options:
• Whether the Local Module transmits VGA (default) or RGB video signals to
the Remote Module, and if RGB, which signals and how (jumpers JP6, JP10,
and JP11).
• Whether the Local Module transmits HSYNC (default) or CSYNC to the
Remote Module (jumper JP2).
• Whether the Local Module uses automatic (default) or manual gain control
(jumper JP3).
• Whether the Local Module expects to transmit into 62.5/125-µm (default) or
50/125-µm fiber (jumper JP5).
If you need to set the unit for a non-default option, open the Local Module—being
sure to take all reasonable precautions against static electricity—by unscrewing the
upper part of its casing. (The jumper locations on the motherboard are shown in
Figure 3-1.) Then set your desired jumpers as described in Sections 3.2.1, 3.2.2,
3.2.3
, and/or 3.2.4, and then close the unit back up.
