2.2.1 Setting Jumpers
You can configure your BRAV-7302 to match the needs of your application by setting the jumpers. A
jumper is the simplest kind of electrical 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”. Sometimes a jumper will have three
pins, labeled 1, 2, and 3. In this case, you would connect either pins 1 and 2 or pins 2 and 3.
Figure 2.1
The jumper settings are schematically depicted in this manual as follows:

Figure 2.2
A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the
best hardware configuration for your application, contact your local distributor or sales representative
before you make any changes.
2.3 Jumper Location
The BRAV-7302 high-performance Box Computer has a number of jumpers inside the chassis that allows
you to configure your system to suit your application. The table below shows the function of each of the
board’s jumpers:

If you encounter the followings
a) CMOS data becomes corrupted.
b) You forget the supervisor or user password.
you can reconfigure the system with the default values stored in the ROM BIOS.
To load the default values stored in the ROM BIOS, please follow the steps below.
1. Power-off the system and unplug the power cord.
2. Set CMOS pins 2 and 3 to On. Wait for a few seconds and set CMOS back to its default setting,
pins 1 and 2 On.
3. Now plug the power cord and power-on the system.
