B.1 Description

1. Modulator output is turned off before reprogramming modulator functions that may alter
the output spectrum through the front panel, and the user is required to enter "Yes" to re-
enable output after the change. When using the terminal, the modulator is turned off
while re-programming modulator functions that may alter the output spectrum, and the
user is required to manually turn on the output after the reprogramming.
2. Modulator output is turned off before reprogramming modulator functions that may alter
the output spectrum through the front panel, but the output is automatically turned on after
the change. When using the terminal, the modulator is turned off while re-programming
modulator functions that may alter the output spectrum, and but the output is
automatically turned on after the change.
3. Modulator output is turned off before reprogramming modulator functions that may alter
the output spectrum through the front panel, and the user is required to enter "Yes" to re-
enable output after the change. When using the terminal, the modulator is turned off
while re-programming modulator functions that may alter the output spectrum, and the
user is required to manually turn on the output after the reprogramming (same as "Carrier
On"). Additionally "VSat" mode disables the modulators output is the modems
demodulator does not have signal lock. When signal lock returns to the demodulator, the
modems modulator turns the carrier back on.
4. Modulator output is turned off before reprogramming modulator functions that may alter
the output spectrum through the front panel, and the user is required to enter "Yes" to re-
enable output after the change. When using the terminal, the modulator is turned off
while re-programming modulator functions that may alter the output spectrum, and the
user is required to manually turn on the output after the reprogramming (same as "Carrier
On"). Additionally "RTS" (Request To Send) mode enables the modulator's output based
on the RTS lead of the data interface. When RTS is enabled on the data interface, the
modulator turns on the carrier, when the RTS is disabled the modulator turns off the
carrier.
