Chapter 3 Hardware Installation
3.2.1 How to Set Jumpers
You configure your card to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch. It consists of two metal pins and a small
metal clip (often protected by a plastic cover) that slides over the pins to connect
them. To "close" a jumper you connect the pins with the clip. To "open" a jumper you
remove the clip.
Figure 3.3 How to Set Jumpers
3.2.2 Terminator Resistor Setup
You can set the terminator resistor if necessary to match impedance. Each port has a
separate resistor.

1. Turn off the computer.
2. Turn the power off to any peripheral devices (such as printers and monitors).

Note! Make sure you have installed the driver before installing the card. We
strongly recommend that you install the software driver before installing
the hardware into your system, since this will guarantee a smooth and
trouble-free installation process.
Warning! Turn off your PC's power supply whenever you install or remove the PCI
communication card or its cables. Static electricity can easily damage
computer equipment. Ground yourself by touching the chassis of the
computer (metal) before you touch any boards.
