The SL70R can use altitude data from either a standard gray code altitude input or from
the host system.
If using the gray code altitude input, connections can be made directly from the SL70R to
the altitude source. Isolation diodes are included within the SL70R. Make sure a common
ground connection exists, or connect a ground wire between the source and the SL70R.
The altitude source must be accurate to within ±125 feet, 95% probability, and have a
resolution of 100 feet (the host input resolution may be better than 100 feet).

The SL70R includes a self test that is executed every time the unit is turned on that
checks the receiver and transmitter operation as well as other internal functions.
The host system should verify that the SL70R does not report a failure indication when
turned on.
NOTE: The system status message reports the failures.
