The Drive Chain screen is basically an exciter control and monitoring screen. It has
a power reading for each exciter output and allows the operator to select AUTO or
MANUAL switching mode for the drive chain when the optional dual drive system
is installed. Specifically it includes:
a. The operational and on-air status of 1 or 2 exciters (the second exciter is
optional) as well as the status of the ASI input to each exciter.
NOTE:
The standard V-XCAST exciter comes with only 1 ASI input. A second ASI
input with switching capability is optional.
b.
The DCU or Drive Control Unit status and power output to the PA modules.
The DCU is an exciter switcher and a directional coupler to monitor exciter
power. For multiple cabinet system, the DCU also contains a splitter to drive
the second cabinet.
c.
A Dual Drive Chain Control box (located at the bottom of the screen). This
section will be grayed out for single exciter systems. For dual exciter systems
