® NS Geode Flex ATX SBC POS-7551 for POS Applications On-board 16 MB DRAM 1 x DIMM Digital I/O (optional) SDRAM CompactFlash™ socket ATX power (backside) connector IrDA port ™ NS Geode GX1- 233 embedded CPU ISA bus expansion 2 EIDE (40 pin & 44 pin) PCI expansion bus 44 pin LCD connector 2 USB/RJ-45 PS/2 keyboard/mouse RS-232/parallel/CRT port AC97 Audio (optional) Introduction Features The POS-7551 is a flex ATX, low cost, fanless Geode ™  NS Geode™ GX1-233 processor on board GX1-233 MHz CPU board specially designed for POS and  Fanless operation other related applications that require many I/O connections on a rugged and affordable platform. This  VGA/LCD controller with Universal Memory Architecture board is perfect for uses such as supermarkets, retail  Supports 18 bit TFT display stores, hotels and restaurants, public transit systems,  10/100 Mbps PCI ethernet interface with wake-on-LAN entertainment appliances and medical equipment to name support a few.  4 COM ports with power line support The POS-7551 is made with industrial grade construction that can better withstand 24 hour a day use, high  Digital I/O (2 in & 2 out) vibration, shock, exposure to humidity, moisture and heat.  2 parallel ports The GX1-233 processor allows for fanless operation that  2 x USB virtually eliminates heat buildup problems that has traditionally been the number one cause of failure in  4 Mbps FIR enclosed chassis POS systems.  Socket for CompactFlash™ The POS-7551 has one ISA and one PCI expansion slot  AC97 audio interface and four digital I/Os plus four on-board serial ports each  16 MB onboard DRAM with +5 V/+12 V power. Supported peripherals range from bar code scanners, card readers, printers, cash drawers  ATX power connector etc. The POS-7551 uses a standardized layout based on the Flex ATX form factor. It is 100 % PC compatible and is ready for use with any existing PC software or hardware. Other on-board industrial features not found on conventional motherboards include a watchdog timer for dependability during unmanned operations, and CMOS backup to Flash ROM. An on-board ComactFlash™ socket can support up to 256 MB. www.advantech.com/epc POS-7551 Specifications Standard SBC Functions Ethernet Interface  CPU: Embedded low power NS Geode GX1-233  Chipset: RTL 8139C  BIOS: 2 Mbit Flash BIOS, supports Plug & Play,  Ethernet interface: PCI 10/100 Mbps Ethernet.
