t the rear of the unit are two DB-9, 
subminiature, female connectors.  These are 
provided for communications links to a 
computer or sophisticated monitoring device. 

SIGNAL PORT DB-9 provides open collector type 
closures that typically signal Utility Interrupt, Low 
Battery and Inverter Active conditions.  A system 
shutdown feature is also available on this port.  
Applying a +5-12V signal across the appropriate 
pins will cause the system to shutdown in battery
