CDM-600/600L Open Network Satellite Modem Revision 3
Appendix E MN/CDM600L.IOM
E–17
CONFIGURATION
Æ TX-PARAM
TX:OFF FREQ=13955 MHz ATT=23 dB
AGC=OFF
Select the parameter to edit – TX, FREQ, ATT, or AGC – using the [
←][→] arrow keys, then use
the [
↑][↓] arrow keys to modify that parameter setting. Press [ENT] when done. Observe the
following:
TX (Tx State) Select ON or OFF.
FREQ
(Frequency) Edit the Tx frequency by first selecting the digit to be edited using
the [
←][→] arrow keys, then change the value of the digit using the [↑][↓] arrow
keys. Press [ENT] when done.
Note: The frequency limits of the KST-2000A are known and the frequency
values are constrained accordingly.
ATT
(Attenuation) Edit the attenuation value by first selecting the digit to be edited
using the [
←][→] arrow keys, then change the value of the digit using the [↑][↓]
arrow keys. Press [ENT] when done.
AGC (Automatic Gain Control) Select ON or OFF.
CONFIGURATION
Æ RX-PARAM
(Displayed only when the ODU is a KST-2000A unit)
RX:OFF FREQ=11950 MHz ATT=20 dB
REF=087
(Displayed only when the ODU is a KST-2000B unit)
RX: FREQ=11950 MHz ATT=20 dB REF=087
BAND=B
Select the parameter to edit – RX (KST-2000A only), FREQ, ATT, REF, or BAND (KST-2000B
only) – using the [
←][→] arrow keys, then use the [↑][↓] arrow keys to modify that parameter setting.
Press [ENT] when done. Observe the following:
RX (Rx State, KST-2000A only) Select ON or OFF.
FREQ
(Frequency) Edit the Rx frequency by first selecting the digit to be edited using
the [
←][→] arrow keys, then change the value of the digit using the [↑][↓] arrow
keys. Press [ENT] Press [ENT] when done.
Note: The frequency limits of the KST-2000A are known and the frequency
values are constrained accordingly.
ATT
(Attenuation) Edit the attenuation value by first selecting the digit to be edited
using the [
←][→] arrow keys, then change the value of the digit using the [↑][↓]
arrow keys. Press [ENT] when done.
REF
(Reference) Edit the Internal 10 MHz Reference value by using the [
↑][↓] arrow
keys – the value will scroll between 000 and 255. Press [ENT] when done.
NOTE: The Internal Reference is adjusted in the factory to be very accurate
with the default setting of 087. This parameter is made available to
compensate for the long-term frequency drift of the oscillator.
BAND=? (LNB Rx Frequency Band, KST-2000B only) See next item for further details.
