2.2.1 Data Interfaces
Note: Refer to Chapter 1 for description of the available data interfaces.
CAUTION
To avoid damaging the demodulator, always disconnect the power
before removing or installing a data interface.
The data interface is a removable, plug-in module that provides a terrestrial connection to
the demodulator. An interface consists of a Printed Circuit Board (PCB) attached to a
faceplate. The faceplate contains connectors appropriate for the interface type, and two
captive mounting screws.
Figure 2-2 is an example of a typical data interface.
