The tDS-724i/734i is a Serial-to-Ethernet device server that is designed to add Ethernet and Internet connectivity to any RS-232/485 device, and to eliminate the cable length limitation of legacy serial communication. It can be easily used for remote controlling of your serial devices through Ethernet network.

By using the VxComm Driver/Utility, the built-in COM port of the tDS-724i/734i can be virtualized to a standard PC COM port in Windows. Most serial devices don't have network ports; tDS-724i/734i turns those devices being able to be connected to the network. Therefore, users can transparently access or monitor serial devices over the Internet/Ethernet without software modification.

The tDS-724i/734i also adds 3000 VDC isolation and +/-4 kV ESD protection component that diverts the potentially damaging charge away from sensitive circuit to protect the modules and equipment from the sudden and momentary electric current.

The VxComm Driver/Utility supports the most popular operating system in the world, including 32-bit and 64-bit Windows 10/8/7/2008/2003/XP. The virtual COM works transparently and is protocol independent, enabling perfect integration with your current central computer. The utility provides an easy configuration interface that can be used to quickly create and map virtual COM ports to one or several tDS-700 series modules. In addition, the utility contains a built-in terminal program, so users can send/receive command/data via the terminal program for basic testing.
 

The tDS-700 series offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functionality using a standard category 5 Ethernet cable to receive power from a PoE switch such as the NS-205PSE. Besides that, the tDS-700 series also accept power input from a DC adapter. The tDS-700 series is designed for ultra-low power consumption, therefore it can reduce the hidden costs from increasing fuel and electricity prices, especially when you have a huge amount of device servers installed. Reducing the power consumption by choosing tDS-700 series will have a positive contribution to environment.

The tDS-700 features a powerful 32-bit MCU to enable efficient handling of network traffic. It also has a built-in web server that provides an intuitive web management interface to allow users to modify the settings of the module, including DHCP/Static IP, gateway/mask and serial ports.

Under normal operating conditions, the TVS diode presents high impedance (appears as an open circuit) to the protected component. When the voltage comes over the limits, the TVS diode avalanches and provides a low impedance path for the transient current. As a result, the transient current is diverted away from the protected components and shunted through the TVS diode. The device returns to a high impedance state after the transient threat passes.
