1.1.1 Applications
When used in conjunction with EFData modems, the CST-5000 is ideal for:
• Single digit carriers up to 2.048 Mbit/s
• Multiple carrier operation over a 36 MHz bandwidth
Because the CST-5000 has a 70 MHz IF, it can also be used for other analog and digital
applications.
Small to medium size earth stations are easily constructed and commissioned with the
CST-5000.
When used with a high-gain antenna, the CST-5000 can also be used as the Radio
Frequency (RF) electronics of a central hub in point-to-multipoint applications, as well as
serving as the terminal for the end points of a network.
1.1.2 Monitor and Control (M&C)
An on-board microcomputer monitors and controls all operational parameters and system
status of the CST-5000. This powerful M&C system enables the user to control functions,
locally or remotely, such as:
• Output power
• Transmit/receive channel frequencies
The system also reports terminal configuration status, as well as fault status of all
CST-5000 components.
The CST-5000 can be initially configured using the:
• Connection of a common ASCII/EIA-232-C terminal connected to the serial port.
A simple command set then allows total configuration control and retrieval of
status information.
• Optional keyboard/LCD (Liquid Crystal Display) controller within the enclosure.
If the indoor unit is a more sophisticated station M&C computer, the serial port can be set
to EIA-485 for bus operation.
For more information on the M&C board, refer to Chapter 5.
