The KeyKing connection line is configured in the ACFA Intellect Software System on the KeyKing Connection Line object's settings pane. This object is created based on a KeyKing ACS object on the Hardware tab of the System Settings dialog.

To configure a KeyKing connection line, do the following:

1. Go to the KeyKing Connection Line object's settings pane.
   
2. Use the up/down buttons to enter the COM-port polling interval in seconds in the Delay, ms field (1).
3. Select the connection method for the KeyKing connection line from the Line type dropdown list: COM port, TCP server, or TCP client (2).
4. If COM port is selected, use the up/down buttons to enter the KeyKing connection line's port number in the Port field (3).
5. If either TCP server or TCP client is selected, then do the following:
   1. Specify the connection line's IP address using the IP address field (1).
      
   2. Use the up/down buttons to enter the connection line's TCP-connection port in the Port field (2).

   A controller connected as a TCP server uses the connection line to listen for messages from devices. A controller connected as a TCP client uses the connection line to send messages about its presence

6. Click the Apply button.

This completes the configuration of the KeyKing connection line.
