7710 Controller Power Output Range Option Capabilities:
13, 14, 18, 19 V @ 500mA (max)
If the user chooses to power the LNB from the controller, he/she should verify the power/voltage
range requirements of the LNB in use and configure the iNetVu
®
7710 Controller according to
those power/voltage requirements.
LNB_LO
This drop-down menu allows the user to change the LNB frequency settings to relock back onto
satellite signal. The Normal operation setting is 10.75 and the controller default setting will
reflect this; users should use the default setting at all times with carriers from table list or a
carrier can be manually entered. If required to change LNB LO, then DVB frequency will also
change as per the following equation: DVB tuner==IF fre (10.75-LO), where LO = the
selected LO from the menu, IF Frequency is the selected/entered Frequency from menu (or
Satparam database table).

There are Six (6) Transponder values in the 7710 Controller for each satellite.
Transponder (0-2) maybe used as horizontal receive
Transponder (3-5) maybe used as vertical receive.
The user may override the default values saved in the controller with his/her transponder
information (frequency, symbol rate, FEC rate).
DVB Type
This drop-down menu allows for the configuration of the DVB carrier to search for. There are
currently two options DVB-S1 and DVB-S2 ACM.
Frequency (KHz), Symbol Rate (sps) FEC Rate
The frequencies listed are in Ku-band.
The user may select from the six (6) available transponders saved in the 7710 Controller, which
are specific to each satellite, or he/she may also enter valid transponder data manually.
DVB will base satellite acquisition on three satellite transponder parameters, them being:
