4.2 DESCRIPTION

The Solid State Power Block Up-Converter unit is self-contained and is intended for mounting near
the hub of the antenna.. Each Up-Converter unit incorporates a DC main power supply and forced
air cooling system, see

Product Outline at page 16. Each unit features a serial RS-485

interface that provides full remote monitor and control capabilities via a computer interface as well
as serial RS-232 interface (that may be used in Terminal mode) and a discrete interface (Relay) for
local or remote monitoring and control of selected functions. A functional block diagram of a
single unit is shown in
