Linux-based device server sprouts USB interface

Aug 10, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive — 4 views

SSV is shipping a version of its Linux-based industrial device server with a USB interface. The IGW/920 (Industrial Gateway 920) comes with Linux 2.6 preinstalled, and can be used to remotely control or monitor devices with serial or USB interfaces, SSV says.

Alternatively, the IGW/920's USB interface could be used for long-term data storage on a USB stick, SSV notes.

The IGW/920 is based on SSV's DIL/NetPC DNP/9200 CPU module. The module, in turn, is based on an Atmel AT91RM9200 SoC (system-on-chip) clocked at 180MHz. The module and device have 16MB of flash and 32MB of SDRAM memory.

The IGW/920's interfaces include:

  • 1 x RS232
  • 1 x RS232/422/485
  • 1 x USB host interface
  • 1 x 10/100 Mbps Ethernet LAN

All interfaces are on screw terminals, except the LAN port, which has an RJ-45 jack. The device has an LED indicating “engaged input voltage,” along with three user-programmable LEDs.

The IGW/920 accepts standard industrial power from 12-24VDC, and operates from 0 to 108 degrees Fahrenheit (0 – 60 degrees Celsius). It measures 4.6 x 3.5 x 0.9 inches (118 x 90 x 22.5mm), and can be mounted on DIN rails.

On the software side, the DNP/920 includes httpd, ssh, and sftp servers. It can also be configured with telnet and ftp servers for low-security applications.


The IGW/920 appears to be available now.

SSV's Industrial Gateway line also includes IGW/800 and IGW/900 models. A CAN bus driver is available for the IGW/900.
