KST-12025 Ku-Band Satellite Terminal

4–8

Rev. 1

DC FREQ

Programs the down converter frequency in 2.5 MHz steps.

On entry, the current down converter frequency is displayed with the flashing
cursor on the first character. Press [

] or [

] to move the flashing cursor.

Press [

] or [

] to increment or decrement the digit at the flashing cursor.

Press [ENTER] to execute the change.

U/C ATTN

Programs the up converter output power attenuation from 0 to 25 dB, in 0.5
dB steps.

On entry, the current up converter attenuation is displayed with the flashing
cursor on the first character. Press [

] or [

] to increase or decrease the output

power attenuation in 0.5 dBm steps. Press [ENTER] to execute the change.

D/C ATTN

Programs the down converter input power attenuation from 0 to 31 dB, in 0.5
dB steps.

On entry, the current down converter attenuation is displayed with the flashing
cursor on the first character. Press [

] or [

] to increase or decrease the output

power attenuation in 0.5 dBm steps. Press [ENTER] to execute the change.

PROGRAM

Programs or clears the current frequency and attenuator settings as one of three
“preset” selections.

On entry, 1*, 2*, or 3* will appear in the window. Press [

] or [

] to move

the cursor from left to right. When the flashing cursor is on any of the “*”s,
press [

] or [

] to turn the “*” ON or OFF. When the “*” is ON, press

[ENTER] to clear stored parameters in the preset location to the left of the “*”.
When the “*” is OFF, press [ENTER] to store the current frequency and
attenuation parameters in the preset location at the cursor. To recall any of the
present selections, use the SELECT menu, and select 1, 2, or 3. Press
[ENTER].

BAUD

Programs the baud rate of the terminal.

On entry, the currently selected baud rate of the terminal will be displayed with
the flashing cursor on the first digit on the second line of the display. To
change the baud rate, press [

] or [

] to select a baud rate from 300 to 9600

bit/s. Press [ENTER] to execute the changes.

ADDRESS

Programs the terminal remote address.

On entry, the currently selected address of the terminal is displayed with the
flashing cursor on the first character. Press [

] or [

] to select the desired

address of the terminal from 1 to 255. Press [ENTER] to execute the change.

PARITY

Programs the parity bit to Even (the default), Odd, or None (for 8-bit).

On entry, the currently selected parity is displayed. Use the Arrow keys to
select Even or Odd. Press [ENTER] to execute the change.

LNA PWR

“ON” means LNA power will be available on the center conductor of the coax
cable. “OFF” means DC power will be removed from the coax cable.

LNA FLT

“ON” means the system will declare an LNA fault when applicable. “OFF”
means all LNA faults will be ignored by the system.

CALIB.

Enables the user to calibrate the LNA. If [ENTER] is pressed, the M&C will
perform an analog-to-digital conversion of the LNA current, and store the
value in the Electrically-Erasable Programmable Read-Only Memory
(EEPROM). During the normal operation, the M&C will monitor the recent
LNA current, and compare it to the stored value. If the LNA deviates by ±
30%, a fault will be declared.

REF ADJ

Allows adjustment of the 10.000 MHz reference frequency to account for long
term drift. DAC setting varies from 0 to 256.
