Houston, TX – March 31, 2010 — Enhancing its extensive USB software suite, Quadros Systems, Inc., a leading provider of real-time operating systems (RTOS) and embedded software, today announced a Remote NDIS (Network Driver Interface Standard) driver for the company’s USB software solution. RNDIS gives embedded developers an easy way to connect a Windows® based laptop or PC to an embedded system. One popular application is to give technicians and field personnel access to deployed systems using a laptop and USB cable.

RNDIS is a standard in the Microsoft Windows operating system and is designed for use with plug-and-play buses like Universal Serial Bus (USB). Embedded systems need a special library to connect to a Windows-based computer using this standard. When a PC is connected to the embedded system the RNDIS interface enables a standard TCP/IP connection over USB. The web browser on the laptop can then view dynamic web pages served up by the HTTP server in the embedded system. Such pages could include device status, maintenance schedules, system logs, and other important information.

Quadros Systems provides all of the software components to support an RNDIS interface including USB device stack, RNDIS driver and the RTXC Quadnet TCP/IP software and web server which makes possible the exchange of Ethernet-like communications. The RTXCusb RNDIS driver is a standard implementation for USB connectivity to a PC or laptop and does not require any custom Windows drivers.

RTXCusb is a suite of stacks, class drivers and controller drivers for host, device and OTG implementations in embedded devices. It supports USB 1.1 and 2.0. This development solution was specifically developed to support the growing number of embedded developers who want to integrate USB plug-and-play functionality into their products. RTXCusb and the RNDIS driver can be used with many real-time operating systems.

“USB has become the dominant communications interface for embedded devices,” said Stephen Martin, vice president, sales and marketing for Quadros Systems. “With the availability of USB controllers on many microcontrollers, OEMs are finding new ways to improve their products, including better ways to support and maintain their deployed products. USB connectivity has almost completely replaced RS232 and other serial interfaces for connecting PCs to embedded systems.”

The RTXCusb host software supports OHCI, UHCI and EHCI standards side and offers class drivers for mass storage, human interface (HID) and printer. Device side drivers include mass storage, serial emulation and now, RNDIS. The RTXCusb class driver structure is readily extensible to support other classes and applications.

Availability

RNDIS for the RTXCusb suite is available immediately in source code as an add-on to the RTXCusb device software. The price for the RNDIS driver license starts at $2900.
