A Taiwanese embedded-computer vendor has announced a rugged, Linux-based computer equipped with a router and switch. The Korenix JetBox 9300 is based on an ARM9-based Atmel 180MHz RISC processor, and includes a five-port Ethernet router and a lightweight managed switch.

Korenix dubs the JetBox 9300 an “industrial communications computer” and suggests it would be suited to remote, autonomous applications such as a vending machine computer. The JetBox 9300 can self-monitor vending-machine operations, including temperature and power status, says Korenix, and notify a remote computer when supplies or repair attention is required.

Based on Linux 2.6.21, the JetBox 9300 offers 64MB SDRAM, two USB 2.0 ports, two RS-232 ports, two RS-232/422/485 ports, four digital inputs, four digital outputs, one SD card slot, and a watchdog timer. The fanless, 2.6 x 5.9 x 4.7-inch, 1.5-pound computer is housed in a rugged, aluminum alloy chassis, says Korenix. The computer is said to offer anti-vibration and shock resistant protection, as well as IP30 protection against physical intrusion.

The JetBox 9300's router offers a combination of WAN and LAN connections, and supports advanced features like static routing, NAT (network-address translation), DMZ (de-militarized zoning), and firewalling. The switch is said to support management via SNMP (simple network management protocol) v1/ v2c/ v3, and to offer QoS (quality-of-service) and 802.1Q, port-based VLAN capabilities.

Specifications provided by Korenix include:

  • Processor — 180MHz Atmel ARM9-based RISC
  • Memory — 64MB SDRAM (expandable to 128MB); 1 x SD card slot
  • LAN — 5 x 10/100 base TX Ethernet (RJ-45 connectors)
  • USB — 2 x USB 2.0 (host)
  • Serial port — 2 x RS-232; 2 x RS-232/422/485 (RJ45 connector)
  • Power supply — DC-input 12 to 48 VDC (-48VDC)
  • Dimensions — 2.6 x 5.9 x 4.7 inches (66 x 149 x 121 mm)
  • Weight — 1.54 pounds (700g)
  • Operating temperature — -20 to 70 deg. C (-4 to 158 deg. F), at 5 to 95% relative humidity
  • OS — based on a Linux 2.6.21 kernel

JetBox 8220
Korenix sells three other Linux-based JetBox industrial computers:

  • 8210, based on a 416MHz Intel XScale PXA270 processor
  • 8220 (pictured), based on a 500MHz AMD Geode LX800
  • 8100, also based on a 500MHz AMD Geode LX800

The company also sells a variety of “Jet” media converters, Ethernet switches, and other networking equipment.

Availability

The JetBox 9300 appears to be available now, at an undisclosed price.
