Quatech's ThinQ serial device servers are engineered to Motorola® digital dna™ standards featuring a PowerPC® core with an on-board RISC communications processor. This Dual-CPU design, 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 or latency issues.

Easy to set up and install, ThinQ serial device servers are up and running on your network in 10 minutes or less. A unique Installation Wizard automatically searches for and identifies any ThinQ unit attached to the network, even searching remote subnets if needed. No client software is installed on your PC, just a small set of drivers that configures each ThinQ serial port as a new COM port on the PC. This allows software applications to access the attached serial device as they are designed to, with no custom programming needed. Simply point your software application to the new, "virtual" COM port and you're all set!

Do you have two serial devices that communicate directly with each other and you wish to replace the short serial cable using the distances 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.

ThinQ RS-232 serial device servers are available in single port and multi-port (two, four and eight port) versions for asynchronous serial devices. Multi-port models are available with DB-9 or 10-pin RJ-45 serial connectors, but custom 10-pin adapters are available for converting ports on the "D" models to RJ-45 for added cabling flexibility and better support for a mixture of serial devices.

ThinQ units are housed in a solid metal case suited for rugged industrial environments and a surge suppression option is available, as are DIN rail mounting for individual units, and rack mount kits for multi-port models.
