AST RESEARCH, INC.        TECHNICAL BULLETIN # 1618          11/05/96 
 
 
 
TITLE:  Ascentia P or J Port Replicator
 
 
ISSUE 
 
   Port replicators are specifically designed as a convenient 
   one-step connection to multiple desktop devices, and do not 
   initiate a docking event within Windows 95. Our Port replicators 
   meet specifications as outlined by Microsoft.
   
   This issue applies to all Ascentia J and P systems.    

 
BACKGROUND 
 
   The port replicator signals to the system that it is attached by 
   changing the active low replicator (pin 31) from a HIGH to LOW 
   condition, when an optical sensor on the replicator is activated 
   by locking the replicator in place. 
   
   The DKING and DKINTR signals are not used by the replicator and 
   will have no bearing on this configuration. 
   
   The function of the replicator pin is to inform the power 
   management circuit within the system, to take its supply from the 
   replicator input. This pin also allows the circuit to switch the 
   supply voltages to the replicator, once the unit has been locked 
   into place.    

 
ACTION 
 
   None required. The system is operating as designed.
