RESET_nIN 

Input 

Controls HW_SHUTDOWN input on Telit X910 
modem, tie low for 800mS to activate.  
Internally pulled up to VCC with 57k resistor.  
Drive with open collector output.  Assert only 
in an emergency as the module will not 
gracefully exit the cellular network when 
asserted.

No Connection 

ON_OFF 

Input 

Modem On/Off signal.  Assert low for at least 1 
second and then release to activate start 
sequence.  Drive with open collector output.  
Internally pulled up to internal I/O rail with 
200k pull up. Do not use any external pull ups.
