KST-12000 Ku-Band Satellite Terminal Revision 4
Operation MN/KST12000.IOM
REF ADJ Allows adjustment of the 10.000 MHz reference frequency to account
for long term drift. DAC setting varies from 0 to 256.
XFLT ENABLE Enables or disables the external fault input. For use with external
Traveling Wave Tubes (TWTs).
On entry, the currently selected parameter will appear. Use the arrow
keys to select ON or OFF. Press [ENTER] to execute the change.
When ON is selected, all of the uplink external faults will appear in the
front panel monitoring menus and fault menus. When OFF is selected,
all of the uplink external faults will be masked in the front panel
monitoring menus and fault menus.
RSW MODE Used in redundant systems only. “INDEP” means uplink and downlink
switch independently. “DEP” means a fault in either UL or DL, and both
will switch over.
LOCK MODE If the system is placed in the Lock mode, none of the above parameters
can be changed. This is to prevent accidental changes of the operation
conditions by unauthorized personnel. The mode must be changed to
Enable in order to change the existing configuration.
