Notes to the Table
Direction refers to the direction of signal flow as viewed from the
printer.
Return denotes “twisted-pair return” and is to be connected at
signal-ground level. When wiring the interface, be sure to use a
twisted-pair cable for each signal and never fail to complete con-
nection on the return side. To prevent noise effectively, these
cables should be shielded and connected to the chassis of the
system unit and printer, respectively.
