Sets the AMWX Tuner's squelch level, from 0% to
100%. The default squelch level is about 55%.
Output:
<
AM_SigStrength >
Indicates the AM signal strength.
The analog values will range from 0 (for no signal) to
65535 (maximum signal strength).
Input: < AM_SignalSrc > Sets the AMWX antenna signal source. Valid analog
values are as follows:
0 = Internal Loop A
1 = Internal Loop B
2 = External Plus Loop A
3 = External Plus Loop B
No other values are valid.
Output: < AM_SigSrc-F >
Indicates the current AMWX antenna signal source.
The analog values will range from 0 to 3.
Input: < AM_Presets >
Selects an AM station preset to Recall or Save.
When the <
AM/WX_Save_Preset > input is high, the
tuner saves the selected preset. When
<

selected preset.
Valid analog values range from 0d (for Preset 1) to
4d (for Preset 5). No other values are valid.
Outputs: < AM_Preset1 >
through
<
AM_Preset10 >
Indicates the frequency of the corresponding preset.
For example, if Preset 4 is AM station 820, then
<
AM_Preset4 > will equal 820d.
Outputs: < WX_Preset1 >
through < WX_Preset5 >
Indicates the weather station channel number of the
corresponding preset. Analog values range from 1 to
7.
Example Program
The example program for the TV/FM Tuner also demonstrates the various features
of the AMWX Tuner. Download the example program from the Crestron FTP site,
ftp://ftp.crestron.com/Examples , (search for C2N-TTVFM.Basic Example.zip).
Uploading and Upgrading
Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects after their
development to the system and network devices. However, there are times when the
files for the program and projects are compiled and not uploaded. Instead, compiled
files may be distributed from programmers to installers, from Crestron to dealers,
etc. Even firmware upgrades are available from the Crestron website as new features
