Type A Cable Termination
If the PanelView is the last device on a physical network, it must be
terminated. The recommended connectors (page 6) have integral
terminating resistors. Terminate the cable by moving the termination
switch on the connector to the ON (Terminate) position.
If you are using a connector that does not have terminating resistors,
terminate the cable as shown below.
