1. INTRODUCTION
The AR-B1641 Series is a half-size tualatin Pentium®III/Celeron PIC Single Board Computer. Targeting on the rapid
growing networking, and telecommunication markets, the AR-B1641 Series are designed with Intel Dynamic Video
memory technology, and One-10/100M Base-TX Ethernet chips. This makes the AR-B1641 Series a perfect
solution for not only popular Networking Applications like Firewall, Gateway, and e-Server, but also for CTI
(Computer Telephony Integration) equipments such as PBX, Digital Logger, etc.
It accommodates up to 512MB SDRAM for demanding applications. Its 6-layer printed circuit board combining with
noise-tolerant and low power consumption CMOS technology enables the AR-B1641 Series to withstand any harsh
industrial environments very well.
The AR-B1641 Series SBC comes with hardware monitoring that monitors system and CPU temperature, system
voltages, fans Speed and CPU and chassis fan speeds to prevent unexpected system failures by warning the user
of adverse conditions. The power management feature provides power savings by slowing down the CPU clock,
turning off the monitor screen and stopping the HDD spindle motor to conserve energy. If the system stays idle for
certain period of time
Other standard specification include two serial ports (one RS-232 and one RS-232/422/485 selectable), one
multi-mode (ECP/EPP/SPP) parallel port, one floppy drive controller, and one PS/2 keyboard / mouse interface.
The built-in PCI Enhanced IDE controller supports up to four IDE devices and Ultra ATA / 100/66/33 bus master
modes.
For other more simple application, there is B version with one LAN.
