2.1 Introduction
The following sections show the internal switch settings and the external connectors and pin assignments
for applications.
2.2 Switches
The SIGM-3250 box computer has a number of switches 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 switches:

2.2.1 CLEAR/COMS -Clear CMOS Data
Picture 2.1: CLEAR/COMS
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. Dial the dip switch to CLEAR mode, stay for 5~6 seconds, and then revert to CMOS mode;
4. Power-On the computer, press the Del key to enter the BIOS setting and reload the optimal default value;
5. Save and exit the Settings.

2.2.2AT/ATX Power on mode selection
Picture 2.2: AT/ATX
The SIGM-3250 provides an AT/ATX SW, which users can set Power-on mode by it. When you dial it at
AT, it means power on byAC Power; When you dial it at ATX, it means power on by Power button.
2.2.3 ACC/Family Mode selector switch
Picture 2.3: ACC/Family
The SIGM-3250 provides ACC/Familyswitch, and users can set the on-off mode of the machine by pushing
the switch with tweezers. When you put it to ACC mode, it means that power on or power off will delay,
until the voltage is stable; When dialed to Family, the machine is on and off normally.
