LNB Config
Use the drop-down list to select Disable or 18V, tone off, band 3.
These are the only valid selections when using LPOD
LNB bias functionality with standard single-band LNBs.
Use the drop-down list to select Through State (unmute LNB) or Off State
(mute LNB).
Use the drop-down list to select this feature as either Enabled or Disabled.
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 Chapter 5. SERIAL INTERFACE OPERATION 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.
Click [Submit] to save.
Calibrate LNB Current
Calibrate the LNB only when it is running at nominal operating conditions.
The value provided here (in mA) is intended as a reference point. The alarm upper and lower
thresholds are determined by this value and the LNB current window setting.
Click [Calibrate] to perform an LNB calibration and display the updated read-only value.
