Vega ASV-1 Operating Manual
Test Alt Encoder:
This is a handy function to test the ASV-1 transponder interface once the installation has been completed. The serial out-
put will output specific altitudes which can then can be used to test the serial RS232 output and the parallel gillham output
if using a CNV-ALT converter. The ASV-1 will resume the normal output of the indicated altitude upon exiting the test func-
tion.
The following codes are outputted:
Altitude
-1000ft
-900ft
-700ft
-400ft
-200ft
800ft
2800ft
6800ft
14800ft
30800ft
Each altitude reporting code line must be tested for integrity of connection if at any time the aircraft connections to the
transponder or altitude data source have been removed and reconnected. Integrity of the connections may be verified by
performing a test of mode C function of the transponder system.
Warning: Do not use this function while in flight as incorrect altitude information will be sent to
the transponder.
