Quatech Inc.â€™s two Device Server models, the QSE-400D and ESE-400D, offer high data transfer rates and low latency and are ideal for industrial and commercial applications. The QSE model is equipped with four serial ports and the ESE has eight serial ports that can be software-configured for RS-232, 422 or 485 operation on each available port. Multi-color LEDs let users know at a glance which interface is being used on each port, and radio buttons in the browser interface allow users to configure the ports in seconds. The 400D series processor allows integrators to easily network-enable even the most timing-sensitive applications and equipment. Industrial sensors, CNC machines, automated meter readers, biometric equipment and other serial devices can operate flawlessly over a network, as the 400D series provides the absolute minimum data transfer time possible.
