For most applications you should leave this jumper installed. However, if you are
using the Extender to connect a VGA video card or other VGA source to an RGB
monitor, remove this jumper as shown in Figure 3-3. (This causes the Local
Module to generate a CSYNC signal for transmission to the Remote Module.)

If you’ll be using automatic gain control (AGC) in your Extender system, leave the
jumper ON the JP3 jumper posts. (We recommend this factory-default setting.)
But if you’ll be controlling the gain manually (see Section 5.2), remove the jumper
from these posts as shown in Figure 3-4. (Whichever way you set this jumper, make
sure that jumper JP8 in the Remote Module is set the same way.)

If you’ll be using fiberoptic cable with a 62.5/125-µm diameter in your Extender
system, leave the JP5 jumper posts empty. (This is the factory-default setting.) But
if you’ll be using 50/125-µm-diameter cable, install a jumper on these posts as
shown in Figure 3-5. The Extender does not work with fiber cables of any other
diameter.
