Drop line use:
When CANR-DF is used in a drop line line (the Network A side is toward the main trunk), the
Network A connection is not terminated. The user must remove the built-in terminator by clipping it out of
the circuit.
Some specifications for the terminating resistor are:

Important: Per the DeviceNet and SDS specs -- do not terminate devices on drop lines.
