The Kansas City Tracker/Tuner is an
8-bit PC board which will operate
in an open ISA slot, in IBM-
compatible computers, ranging from
XT's to
Pentium systems. It does not use
any hardware interrupts, parallel
ports or serial ports. The card
occupies 4 consecutive I/O
addresses,
starting at the address specified
on the board's DIP switches. It has
its own DB25-type port, which is
used to connect to both a rotor
controller, and either a dual band
radio or two single band radios.

The KCT interfaces with a rotor
controller in two ways.

First, it requires input from the
Elevation and Azimuth
potentiometers
to determine their position. This
must be in the form of DC voltages
that vary from 0V to about 5V, as
the antenna moves from one end of
travel to the other. It then uses
an A/D converter to generate a
voltage/position table. It can then
send the antenna array to any
specified position.

Second, the KCT has 5 outputs which
can activate the controller's
up/down, left/right, and brake-
release inputs. These lines can
pull the
desired input to ground, and cause
antenna motion in the corresponding
direction. Manual control through
the controllers switches is still
possible.
