STEPP II HARDWARE DESCRIPTION VERSION 
1.01 
The FALCOM STEPP II comprises also two audio interfaces available on the 
provided connectors: 
 
Two analog audio interfaces, each with a balanced analog microphone 
input and a balanced analog earpiece output. Both analog interfaces 
provide supply circuits to feed active microphones.
 
 
This means you can connect up to two audio devices in any combination. An 
audio interface allows the direct connection of a headset. An example of a 
possible installation is shown in the Appendix of this manual. The voice 
channel of STEPP II allows you to conduct a normal telephone conversation. 
For this, STEPP II operates in free-speech mode. Requirements are to connect 
a loud speaker (pins 13 and 15) and a free-speech microphone (pins 14 and 16) 
on the 16-pin connector interface of the STEPP II. 
After that the terminal is connected to the aforementioned power supply, its 
actual status is displayed by three LED’s on the front side of terminal. The 
red LED indicator will flash during the internal initialization of STEPP II 
terminal. If ambient temperature and the voltage of external connected 
battery are correct the red LED indicator will switch off.
