8.1.5 - Tuner

The antenna ODU has an onboard DVB receiver to lock onto a satellite but the preferred

method for lock, identification and fine tuning under normal operation is to use

information queried and returned from the modem itself.

If the system is set to generic mode, the antenna’s lock and fine tuning is completed

using the onboard DVB receiver. This second method requires no modem

communication to the controller but it still requires a modem to be present in order to

power the LNB. Winegard technical support will in times use this mode to troubleshoot

issues, but it is not recommended for normal operation.

8.1.6 - Software

There are several safety features built into the antenna system. These features

automatically stow the antenna if certain criteria are met. These include loss of receive

signal lock, detected motion (pitch, roll, velocity) as well as turning the power off to the

system by pressing the power button on the IDU.
