The power and flexibility of the 400 series is derived from the industry's best processor, a PowerPC® from Freescale™ (formerly Motorola® Semiconductor). This processor is part of a world-class architecture that offers the lowest latency available anywhere. In addition, the auto-sensing 10/100 Ethernet interface, and Quatech's proven high-speed, 921k-baud serial technology offer the best performance in the industry and ensure that your critical business applications won't be harmed by data throughput issues.

The new 400 Series models introduce a new software-selectable, RS-232 / 422 / 485 multi-electrical interface (MEI) to the ThinQ product line. They are currently available in one and two port units, but higher port counts will be released in 2005. Unlike many competing two-port models on the market, the DSE-400D has MEI on both ports. Already the performance leader, the DSE-400D is now the flexibility leader as well.

An intuitive Installation Wizard gets ThinQ up and running in just minutes, automatically searching local and remote subnets for the correct model attached. Network settings automatically assigned by DHCP networks are displayed for confirmation, or change to a static IP address easily using the Installation Wizard - no Telnet sessions, MAC address data entry or special cables are needed. ThinQ can be managed through the Windows® Device Manager interface or a Web browser, for continued ease of configuration and maintenance long after the initial installation is completed.

Do you have two serial devices that communicate directly with each other and you wish to replace the short serial cable using the distances made possible with Ethernet technology? The serial tunneling feature now available on every ThinQ model can do this much easier than you imagine. Set up one ThinQ unit as the master, tell it the IP address of the remote ThinQ unit, and plug them both in. The master will locate and configure the remote unit for you, right out of the box! The two serial devices will then communicate as if connected by a short serial cable; the Ethernet portion will be invisible to the devices.

For remote service and monitoring applications, try our new AutoTCP feature. The serial port can be set up to act as a TCP Client, requesting a connection whenever the serial device is attached and powered on or, if you prefer, whenever serial data is ready for upload to the host computer. You can leave the connection on, or disconnect from the host after a specified period. But when a service request from a remote monitoring PC (with a specified IP address) arrives, ThinQ will act as a TCP server, allow access to the serial device to the monitoring PC, and go back to Client mode when the Server session is finished. This is perfect for remote troubleshooting, support and report generation!

Quatech's "virtual" COM drivers and the Installation Wizard are available for Windows NT4/2000/XP and Linux. ThinQ can be deployed successfully in almost any OS environment however, including Unix and Solaris, via Raw TCP (socket) mode or Quatech's exclusive IntelliSock™ mode. IntelliSock is a flexible and powerful TCP socket service for custom applications that provides capabilities beyond that of Raw TCP mode, such as re-configuring the serial port in the packet header sent with each data transfer. A free Software Developer's Kit (SDK) explains more about this unique feature.

The 400 Series ports can be configured for RS-232 or for RS-422 or RS-485 asynchronous communication in either full-duplex or half-duplex mode. ThinQ units are housed in a solid metal case suited for rugged industrial environments, and DIN rail mounting kit and surge suppression options are available.
