It seems like 119? But isn't that Circular? I would have to plug the coax into the (C Port) correct?
I would start there, but it's a very powerful Sat - too easy to find when setting up a motor. Yes, you would connect to the LNBs "C" port.
In the Receiver's setup menu:
LNB Type: Standard / Single
LNB L.O. / Freq: 11250
I would not even connect the cables to the Motor, connect directly to the LNB.
These are the 3 things you need to set for the Dish / Motor:
Motor Latitude Scale: 34.1
Azimuth (mag.): 167.1° using Compass (leave the bolt loose enough to twist on the pole)
Dish Elevation: 39 or best signal
After you get the 119 Sat, power down the receiver, connect the motor, connect to the LNBs "L" port, and try for try for Satmex 5 @ 116.7.
In the receiver's setup menu find Satmex 5, enter LNB info:
LNB Type: Standard / Single
LNB Freq: 10750
Motor: USALS and enter your Location, Lat "North" and Long "West"

Have the Receiver drive to the Sat, try to get signal.
