3.4 Side Panel - Left Side
On the side panel (Figure 3-1) to the left are the two Receive IF ports, ‘A’ and ‘B’, which
are both BNC female. Connection is made to the pair of Modems using Comtech EF Data
P/N CA/BNC 75 OHM ( 75
Ωapplications) or Comtech EF Data P/N CA/BNC 50 OHM
( 50 Ω applications).
Additionally, a small opening near the rear of the unit provides access to two switches,
which determine the conditions dictating an automatic switchover. This is described in
detail in Chapter 7.
