3.By inserting board to the far end, it is locked by the lock piece inside.
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.
Important! 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 71).
