The nodes at each end of the network must be terminated. Install a jumper
wire between terminals 5 and 6 to enable the impedance built into the
module.
One (not both) of the nodes at the end of the network must have an earth
ground connection for the communication cable shield. For the node
at one end of the network, whether it is the KF3 or some other device,
connect the shield to ground by installing a jumper wire between terminals
1 and 2 of the terminal block.
CAUTION: Be sure no other node on the network has its shield
connected to ground.
Figure 2.3 illustrates proper jumper connections for end nodes.
