Product Description
The CTI-540 Control System can be used to precisely
control a wide variety of devices including heavy-duty pan/tilt heads,
tracking pedestals, satellite antennas, and other positioners. The CTI-540 is customizable to accommodate a large range of
motor output voltages, position sensor types, and user interfaces.
Two parts comprise the CTI-540 System - the Antenna
Control Unit (ACU), and the Graphical User Interface (GUI).
Antenna Control Unit (ACU)
The heart of the CTI-540 Antenna
Control System is the rack mounted ACU.
The ACU has an embedded microprocessor to allow control of the
positioner via front panel pushbuttons, a remote hand-held controller,
and/or by remote commands through a serial or Ethernet port (from the
GUI or other device). The
ACU can drive motors on up to four axes, and monitor limit switches and
position sensors to track motion.

Graphical User Interface (GUI)
A Graphical User Interface (GUI) connects
to the CTI-540 ACU’s remote port via a serial or Ethernet
connection. This
GUI can consist of a Touch-Panel, or a Windows application.
Alternatively, message protocols can be provided so
third-party software may be written to control the ACU.
The user interface typically provides the
following functions: Manual
control of all axes, real-time position information for the az
and el axes, automated moves to preset positions, and
configuration & setup of the system.
Many application specific features can be included in the
GUI such as scanning routines and inclined orbit tracking
algorithms.
The CTI-540 Graphical User Interface can be
completely customized to fit many different applications.
