Tiny Serial-to-Ethernet Device Server1. IntroductionThe tDS-700 is a series of Serial-to-Ethernet device servers that aredesigned to add Ethernet and Internet connectivity to any RS-232and RS-422/485 device, and to eliminate the cable length limitationof legacy serial communications. By using the VxCommDriver/Utility, the built-in COM Port of the tDS-700 series can bevirtualized to a standard PC COM Port in Windows. Therefore,users can transparently access or monitor serial devices over theInternet/Ethernet without the need for software modification.tDS-700 device servers can be used to create a pair-connection application (as well as serial-bridgeor serial-tunnel), and then route data between two serial devices via TCP/IP. This is useful whenconnecting mainframe computers, servers or other serial devices that do not themselves haveEthernet capability. By virtue of its protocol independence and flexibility, the tDS-700 meets thedemands of virtually any network-enabled application.Copyright 2018 ICP DAS CO., Ltd. All Rights Reserved.-6 -

Tiny Serial-to-Ethernet Device ServerIn harsh industrial environments, the tDS-700 series (for i version) also adds 3000 VDC and /- 4 kVESD protection component that diverts the potentially damaging charge away from sensitive circuitto protects the module and equipment from the sudden and momentary electric current.To achieve maximum space savings, the tDS-700 is offered in an amazingly small form-factor thatenables it to be easily installed anywhere, even directly attached to a serial device or embeddedinto a machine. The tDS-700 features a powerful 32-bit MCU that allows it to efficiently handlenetwork traffic. The tDS-700 offers true IEEE 802.3af-compliant (classification, Class 1) Power-overEthernet (PoE) functionality using a standard category 5 Ethernet cable that allows it to receivepower from a PoE switch such as the NS-205PSE. If there is no PoE switch available on site, the tDS700 can accepts power input from a DC adapter.Comparison of Device Servers:SeriesPPDSPDSDStDStGWVirtual COM -Programmable ---PoE -- Modbus Gateway --- 1 Sockets/Port10 ve,Entry-levelFeaturesMulti-clientRemarksAbout 20 SocketsProfessionalPowerfulIsolation forDS-715Copyright 2018 ICP DAS CO., Ltd.

Tiny Serial-to-Ethernet Device Server1.2 VxComm TechnologyIn general, writing a TCP/IP program is more difficult than writing a COM Port program. Anotherissue is that perhaps the existing the COM Port communication system was built many years agoand is now outdated.As a result, a new technology, VxComm was developed to virtualize the COM Ports of the tDS-700to allow up to 256 COM Ports to be used on a central computer. The VxComm driver saves timewhen accessing serial devices through the Ethernet without the need for reprogramming the COMPort software on the PC.Copyright 2018 ICP DAS CO., Ltd. All Rights Reserved.-9 -

Tiny Serial-to-Ethernet Device ServerThe VxComm driver controls all the details of the Ethernet TCP/IP programming technique,meaning that, with the assistance of tDS-700 and VxComm technology, your COM Port program willbe able to access your serial devices through the Ethernet in the same way as through a COM Port.Copyright 2018 ICP DAS CO., Ltd.

Tiny Serial-to-Ethernet Device Server1.3 Web Server TechnologyWeb server technology enables the tDS-700 to be configured via a standard web browser interface,e.g. Google Chrome, Internet Explorer, or Firefox, etc. This means that it is easy to check theconfiguration of thetDS-700 via an Ethernet network without needing to install any other softwaretools, thereby reducing the learning curve required for maintaining the device.Copyright 2018 ICP DAS CO., Ltd.
