Connection Ports and Station Ground
The DIA distribution board provides most of the internal connection
between the repeater units, and to external ports. Connectors involved in
the installation are also located on the DIA board. These connectors are
described below. A complete DIA board connector list is found in the
Board and Unit Descriptions section in Chapter 5.
Station ground is detailed below as well.
Station Ground
There is a ground screw (M8) in the repeater that is intended for station
ground (see Figure 3-8). This screw must be used only for station
grounding.
