DKS Enterprises PC Compatible Multi-Door Access Controller 1838 User Manual

 

 

 

 

The access controller is shipped with two memory chips packaged in a separate box inside the 
shipping container.  The memory chips must be installed for the system to operate. 

 

CAUTION!!  Do not install the memory chips with power to the system turned on.  Attempting 
to install the memory chips with power on will irrevocably damage the chips.  Memory chips 
are a static sensitive component.  Discharge any static electricity from your hands by 
touching a proper ground device before removing the control board.  Handle the memory 
chips with care. 

 

1.  The large memory chip socket is colored black and is located in the center of the circuit 

board.  Be sure that the handle is in the un-locked position (pointing up).  Be sure that 
power to the telephone entry system is off. 

2.  Carefully insert the memory chip into the socket.  The small half circular indentation on 

the chip must be to the right.  CAUTION:  Installing the memory chip backwards will 
cause permanent damage to the chip.  Be sure that the memory chip is seated correctly 
in the socket, then move the lever to the locked position. 

3.  Install the small memory chip in the socket located at the bottom of the circuit board.  The 

small circular indentation on the chip must be to the right.  CAUTION:  Installing the 
memory chip backwards will cause permanent damage to the chip.  Be sure that the 
memory chip is seated correctly in the socket.
