4. Connect suitable interface cable (must

be purchased separately) to printer con-
nector and to serial port of your com-
puter. Be sure to tighten screws on both
ends of cable to keep it in place.

  Make  sure  that  you  do  not

have  a  parallel  cable  connected  to  the
printer when you’re using the serial inter-
face. You can switch to the parallel inter-
face without removing the serial board, but
only one cable can be attached at a time.

When the serial interface is installed, the
“Serial I/F” portion of the Menu will be-
come active (see page 73).
