Test Alt Encoder:

This is a handy function to test the ASV-2 transponder interface once the installation has been completed. The serial 
output 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-2 will resume the normal output of the indicated altitude upon exiting the 
test function. 

The following codes are outputted:

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.
