When the F372A/F377A is a unit at both ends, terminator resistance must be
installed. (Confirm with the CC-Link specifications.) At this time, when the DA and
DB signal lines and resistance are to be connected to the connector, be aware
that poor contact may result if the nipping conditions differ between the leg of the
resistance and signal lines. There is a possibility of abnormal operation.
