 +The Monitor F-Type output of the AVP is connected directly to the RF input of the RX1 (RX4 is on the left). There is no up-convertor or attenuator in use.

 +==== RX1 Input Settings ====
 +See Below for the RX1 Demodulation settings.

 +LNB Frequency         5150
 +LNB Voltage           (voltage off) this is because we don't actually have an LNB in our system.

 +Tuner
 +Frequency             4080 (5150-4080=1070. 1070 is the L-Band Freq we set in the AVP)
 +Symbol Rate           31.25
 +Search Range          10000
 +C/N margin alarm      2.0
 +
 +Everything else off.

 +==== RX1 Input Status ====
 +\\ 
 +On the same page as you entered the RX1 demodulation settings, once you have started the receiver service, you should see the following input status.
