Config | LNB

The 'Config | LNB' page (Figure 4-7) is used to configure Low-Noise Block Downconverter
parameters, and display the LNB status for L-Band operation.
LNB Config
•
LNB Current Source: Using the drop-down menu, select this feature as either Enabled or
Disabled.
•
LNB Current Window: Using the drop-down menu, select this feature as either Enabled
or Disabled.
•
LNB Current Window (%): This field defines the size of the LNB Current Window, and
determines the fault thresholds for the LNB current draw.
Any LNB current reading that is outside the window may generate an alarm, a fault, or may
be masked entirely depending on the state of the user configured fault mask (see the MSK
command syntax in Appendix B. REMOTE CONTROL for more information).
For example: If the LNB draws 100mA, and the LNB current fault window is set to the
default value of 30(%), then the allowable current draw for the LNB will be from 70 mA
minimum to 130 mA maximum because the window is +/- 30% centered on the calibrated
LNB current draw.
•
Switch Bias Tee: Using the drop-down menu, select either Through State (unmute LNB)
or Off State (mute LNB).
•
Remote LNB Control
menu, select the control features of the LNB: 22kHz disabled, 13V; 22kHz enabled, 13V;
22kHz disabled, 18V; or 22kHz enabled, 18V.
Once the desired configuration settings have been made in this section, the user should then click
[Submit] to save these changes.
To update the page appearance to the current operating configuration, click [Refresh].
