SIGNAL TYPE AND
NAME DESCRIPTION
Output: < WX_LED-F > Indicates the state of the WX LED on the AMWX
Tuner. This LED is active when the AM Tuner is
set to the weather band.
High/1 = Active (WX LED on);
Low/0 = Not active (WX LED off)
Input: < AM_AutoAntCfg > Sets the AMWX Tuner to auto-configure mode
when the input is high.
In this mode the AMWX Tuner will automatically
select between the internal A and B loop

Inputs: < >,
< AM _ Scan- >
Scans through each AM station on the rising
edge of the input. The scan function only applies
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 TV/FM Tuner when
the unit is in SCAN mode; or from remote
buttons defined on a touchpanel or other
interface. (The AMWX Tuner 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:
1) the local BAND or MODE buttons are
pressed; or
2) a remote band or search button is pressed;
or
3) it wraps around to the original station, if that
station is scannable; or
4) after a maximum number of repeats; or
5) a station is directly entered; or
6) a remote scan +/- or s/- button
defined on a touchpanel or other interface is
pressed.
High/1 (rising edge) = Scan up or down (AM
only); Low/0 = No effect
Output: < AM_Scanning >
Indicates that the AMWX 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
