Protocol
Warning: Before you make any connection be sure that the power
to the printer and the computer is off.
Serial Interface Installation Serial interface installation is a
straightforward process. First lift the cover away from the IC card
compartment. Then take your serial interface unit, and holding it
facing out, plug the connector end into the connector socket in
the compartment, making sure that at the same time the sup-
porting bars slip through the slots. With a cross-point screw-
driver you complete the installation process by screwing the bars
to the printer.
Serial Interface Protocols The serial interface is configured through the DIP switches on the
interface. The serial interface offers two communication protocols: data ready and XON/XOFF.
The first is a hardware protocol and the second is a software protocol. These protocols help to
ensure that your computer doesn't send information to the printer faster than it can print it.
To select a protocol you need to look at the manuals for the programs that you will be using with
your printer. They will tell you which serial protocol they use, select the same protocol for your
printer.
