Chapter 1 Introducing the FX5612 System  

Overview 

The FX5612 is an embedded system with low-power CPU module inside. This user’s 

manual provides information on the physical features, installation, and BIOS setup 
of the FX5612. 

Built to unleash the total potential of the Celeron-M or Pentium-M Processor, Able 

to support 600MHz ~ 1.4GHz CPUs, this system supports two 10/100/1000M Base –TX 
LAN ports, 256MB SDRAM on board, mini PCI socket for wireless LAN, Four USB2.0 

ports, and a VGA controller. 

Each FX5612 has one port for I/O communications. Two RS-232C ports are available.    

The FX5612 is perfect for ATM machines, KIOSK, point-of-sales/point-of- information, 

gaming and infotainment, measurement technology, lotteries, banking and Thin 

Client and small Embedded Control. The unit is only 178.0mm (D) X249.0mm (W) 
X72mm (H).
