''Return'' denotes the twisted-pair return, to be connected at
signal ground level. For interface wiring, be sure to use a
twisted-pair cable for each signal, and to complete the
connection on the return side. These cables should be
shielded and connected to the chassis of the host computer
and the scanner.
All interface conditions are based on TTL level.
