Pin 1 DTR# SIN 2 1 DCD# SOUT DSR# CTS# RTS# RI# GND 50 MX4LS B a t t e r y - l e s s a n d L o n g Li f e D e s i g n Online Manual This Motherboard implements Flash ROM and a special circuit that allows you to save your current CPU and CMOS Setup configurations without the need of a battery. The RTC (real time clock) can also keep running as long as the power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system will recover as usual. ATX Stand-by Power Battery Auto Switch RTC (Real Time Clock) 00:00:00 Auto switching to ATX standby power as long as AC power line is plugged. This smart design increases battery life if you still plug battery on motherboard. Flash ROM CMOS Backup by EEPROM 51 MX4LS C P U O v e r - c ur r e n t P r o t e c t i o n Online Manual Over Current Protection has been popularly implemented on ATX 3. 3V/5V/12V switching power supply for a while. However, new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2. 0V). This motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3. 3V/5V/12V power supply for providing full line over-current protection. 5V (Protected by power supply) ATX Switching Power Supply 3. 3V (Protected by power supply) 12V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason. AOpen cannot guaranty the protection circuit will always work perfectly. 52 MX4LS H a r d w a r e M o ni t o r i n g Online Manual This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will continue to monitor your system's working voltage, fan status and CPU temperature. If any of these systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if existed) to warn the user. Fan Fan Speed CPU CPU Temperature CPU Voltage Detection Circuit AOpen H/W Monitoring Utility Power System Voltage 53 MX4LS R e s e t a bl e F u s e Online Manual Traditional motherboard has fuse for Keyboard and USB port to prevent over-current or shortage. These fuses are soldered onboard that when it is broken (function as protecting the motherboard), user still cannot replace it and the motherboard is still malfunctioning. With expensive Resettable Fuse, the motherboard can be resumed back to normal function after the fuse had done its protection job. Resettable Fuse 54 MX4LS 3 3 0 0 F L o w E S R C a p a c i t or Online Manual The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, MX4LS implements 3300F capacitors, which is much larger than normal capacitor (1000 and 1500F) and it provides better stability for CPU power. 55 MX4LS E nl a r g e d Al u m i n u m H e a t s i n k Online Manual Cool down CPU and Chipset is important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over clocking the CPU. 56 MX4LS O p e n J u ke B o x P l ay er Online Manual Here we are pleased to provide you a brand-new powerful interface--Open JukeBox.
