Step 3: The following options are found in the “Configuration” Screen.
 For DVB Search Method, the Satellite Configuration must be exact as provided by your NOC or
service provider.
Satellite Transmit Polarization Offset:
• In North America and not limited to the rest of the world 1201/1200/1800/1500/Flyaway
Horizontal Receive (Offset = 0), Vertical Receive (Offset = 90)
• 980/740 - Offset = 0 (OMT is adjusted manually)
• If your configuration is correct then you may have a line of sight or coverage issue. For testing
purposes you may try another satellite and DVB carrier. Our controller has many preconfigured
satellites and transponders you may try. C-COM does not guaranty the reliability of these
Frequencies.
• Locate a satellite that covers your GEO location and enter this into the Longitude field. If the
satellite is preconfigured it will auto populate all fields. If 999999 is auto populated this indicates no
working frequencies haven been preconfigured for that satellite and transponder.
• You may also choose to use websites as
http://www.lyngsat.com/ or http://www.tracksat.com/ to
find working DVB transponders. (Frequencies must be converted and entered in L-Band) see next
page for sample.
Conversion Rule:
o Given that: Ku-Band Frequency = 12144 MHz and LNB LO = 10750 MHz (10.75GHz)
o 12144 MHz - 10750 = 1394 MHz = L-Band of 1394000 KHz
****Note: The L-Band Frequency must be in the range of 950,000(KHz) – 2,150,000(KHz)****
