The maximum recommended cable length between the
KFC15/KFCD15 module and the parallel host is 3 m (10 ft).

The cable between the KFC15/KFCD15 module and the parallel
host must be shielded.
For detailed cabling and pinout information see Appendix B,
Cabling and Pinouts. For a discussion of data transfer modes and
other communication issues, see Chapter 5, Communicating with the

Planning for an RS-232C Serial Port
Serial port communication can take place in either full- or
half-duplex mode. If a single KFC15/KFCD15 module per serial
host is used, either half-duplex or full-duplex communication can
take place.
