Satellite Terminal System
Revision 2
Operation
MN/KST2000L.IOM
Note:
Ensure that the termination selected for the HPA output is sized to handle the HPA output
power.
1. Apply power to the KST-2000L. After a few seconds ensure that the green TX
ON LED is flashing, and the fault LED is extinguished. Refer to Section 4 if this
is not the case.
2. Using a KP-10 or PC equipped with a terminal or Windows
based M&C pro-
gram, ensure that you can communicate to the system M&C, via J2, remote con-
nector. (Refer to M&C software manual, part number MN/M&CWIN.IOM)

Data length 7 bits
If the communication parameters for the system are not known, the Windows
based M&C system has a facility that will search all combinations of address,
baud rate, and parity until communication is established with the system.
Using the KP-10 or terminal program, send a miscellaneous command such as
EQUIPMENT TYPE (see appendix B.8) and confirm a response is displayed.
The Windows
based status screen will turn from red to gray when communica-
tion with the KST-2000L is established.
4.1.1 Uplink
Setup
1. Apply a 70 MHz (140 MHz) signal at a known level between –25 and
–45 dBm to the IF IN (J3) connector of the KST-2000L.
Note:
This assumes that the AGC function is selected as ON. The AGC will
not function below a – 45 dBm input level. If the AGC function is selected
as OFF, lower input levels can be used limited only by noise. See section
3.12 for more information on the AGC function.
2. Set the up converter to the desired RF transmit frequency using the appropriate
commands from the KP10 terminal, or Windows
M&C. See the up converter
frequency select command (Appendix B.3). If an error message is received, see
Appendix B.2.3 to determine the cause.
3. Before proceeding, ensure that the HPA is properly terminated. If a directional
coupler and termination is used or an attenuator is used, note the value.
4. Enable external faults, execute the appropriate HPA Power commands. See sec-
tion B.4 HPA commands.
