Nuvo/T2	N/A	Serial

Description:

This driver controls the Nuvo T2 Tuner. This driver supports all variations of the tuner, for both the regular Concerto and Grand, and for all bands XM/AM/FM/WX. The user will be prompted on installation of the type of Tuner used so that the appropriate fields are generated.

Quirks and Limitations:

None.

Connection Details

The parameters are 9,600 baud, 8 bits, one stop bit, no parity. Both regular polling and asynchronous responses are handled by the driver to synchronize fields.
The connection is a standard straight through cable and a 3 wire should be fine.

The installation of the driver also requires the user to indicate which tuner is installed.

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...

The ? symbol in the fields represent the tuner A or B, so there will be versions of that field with the tuner ID A or B
