SIGNAL TYPE AND
NAME DESCRIPTION
Output: <WX_LED-F>
Indicates the state of the WX LED on the C2N-
TAMWX. This LED is active when the C2N-
TAMWX is set to the weather band.
High/1 = Active (WX LED on);
Low/0 = Not active (WX LED off)
Inputs: <AutoAntCfg>
Sets the AM tuner to auto-configure mode when
the input is high.
In this mode, the tuner will automatically
configure the internal A and B loop antennas
and select the A or B loop depending on which
signal is stronger.

to the AM band; it is not supported in the
weather band.
Users can scan for AM stations by pressing the
Up and Down buttons on the C2N-TFM when
the unit is in SCAN mode; or from remote
buttons defined on a touchpanel or other
interface. (The C2N-TAMWX does not provide
Scan buttons.)
The tuner will scan up (+) or down (-) to an AM
station, pause for five seconds, and then
continue scanning to the next station. Pressing
the scan button again stops the Scan operation.
The Scan operation also stops when it wraps
around to the original station.
High/1 (rising edge) = Scan up or down (AM
only); Low/0 = No effect
Output: <AM_Scanning>
Indicates that the AM tuner is busy scanning AM
Stations. The output will be high for as long as
the tuner remains scanning.
High/1 = Scanning; Low/0 = Not scanning

when the unit is in VOL mode; or from remote
buttons defined on a touchpanel or other
interface.
