COAX
The coax cable is connected to the host which communicates in
accordance with the 3270 protocol.
PARALLEL OUT
The parallel output port is connected to the parallel/Centronics in put port
on the target printer (standard parallel out cable supplied with printer
should be used).
PARALLEL IN
The parallel input port can be  connected to the parallel/Centronics out put
on a PC or similar source able to share the printer with the host. For this
connection you need a spare part cable ending in a 25-pole D-Sub
