1.  Introduction

The ADTS

 

405 Altimeter Encoder Option allows the output from encoder altimeters to be 

displayed on either the hand-held terminal or display and key-pad of the unit. The displayed data 

includes the bit pattern and the equivalent altitude decoded from the bit pattern. The unit supplies 

24

 

VDC to power the altimeter encoder electronics circuit and the altimeter vibrator circuit.
