6.1.9. Configuring the 22KHz Tone

A 22KHz tone may be combined with the LNB voltage for universal LNB local oscillator control. The
22KHz tone can be enabled or disabled via the 22KT selection menu. To select the 22KHz tone, select
the CTRL menu item in the first menu level, then use the toggle switch to display the 22KT option and
press the pushbutton to select it.

6.1.10. Setting the LNB Current Threshold Level

The 7807LT-2 monitors the amount of current being drawn by the LNB. Upper and lower thresholds may
be set, which when exceeded will trigger an SNMP alarm. This function may be used to provide an early
warning of impending LNB failure. To set the LNB current threshold, select the CTRL menu item in the first
menu level, then use the toggle switch to display the LNTH option and press the pushbutton to select it.

6.1.11. Default Card-Edge Display

This allows configuration of which operating condition will be displayed as the top-level item on the dot-
matrix display. The default is NORM, which displays "OK" or "LASER FAULT" in the event of a problem
with the laser. To choose an alternate parameter, select the CTRL menu item in the first menu level, then
use the toggle switch to display the DEFD option and press the pushbutton to select it.
