Setting Up Front
Modules
Front module setup consists of setting the jumpers for the DA-6804+D series
modules. Three jumpers that need to be set: J1 and J2 are used for reclockers, and
J3 is designed for channel configuration and enabling remote control.
Figure 2-4 shows the location of the J1, J2, and J3 jumpers.
