4.1.2LOCAL GAIN-CONTROL JUMPER JP3

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 4-3. (Whichever way you set this jumper, make sure that jumper JP8 in the Remote Module is set the same way.)

4.1.3CORE-DIAMETER JUMPER JP5

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 4-4. The Extender does not work with fiber cables of any other diameter.
