5. Secure the board to the three supports using the screws provided.
6. Connect the frame ground wire to the FG terminal tag on the
interface board, as shown in Figure E-6.
7. Reassemble the printer, reversing the procedure described in the
previous section.
Serial Interface Settings
If you are using an optional serial interface, you may need to change
the communications protocol of the printer or the computer for them
to communicate properly. The protocol used by the printer is decided
by one or two groups of DIP switches located on the serial interface
board; the protocol used by the computer can probably be altered by a
software command. It is essential that the printer and computer use
compatible protocols.
