Also, because this interface can be damaged by static electricity, you should prepare the interface card for installation according to the procedure below:

1.While the interface is still in its anti-static bag, place it next to your printer.

2.Place the twin-axial cable from the host computer on top of the anti-static bag; make sure the metal connector on the cable is in contact with the bag.

3.Remove the interface card from the bag and place it on top of the bag next to the twin-axial cable.

4.Set the jumpers on the interface card according to the instructions in the following section.

SETTING THE JUMPERS

A jumper is a small, square plastic object that fits over two terminals (prongs) on the interface card. To connect a jumper, place the jumper over both terminals. To disconnect a jumper, place it over one terminal only. All jumpers are connected when shipped from the factory.

The C82315* interface card has three jumpers, labeled as J2, J5, and J6. The settings for J5 and J6 are different for the different emulations. After deciding on an emulation, set the jumpers according to the tables below.
