Tiny Serial-to-Ethernet Device Server
1. Introduction
The tDS-700 is a series of Serial-to-Ethernet device servers that are designed to add Ethernet and Internet connectivity to any RS-232 and RS-422/485 device, and to eliminate the cable length limitation of legacy serial communications. By using the VxComm Driver/Utility, the built-in COM Port of the tDS-700 series can be virtualized to a standard PC COM Port in Windows. Therefore, users can transparently access or monitor serial devices over the Internet/Ethernet without the need for software modification.
tDS-700 device servers can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel), and then route data between two serial devices via TCP/IP. This is useful when connecting mainframe computers, servers or other serial devices that do not themselves have Ethernet capability. By virtue of its protocol independence and flexibility, the tDS-700 meets the demands of virtually any network-enabled application.

Tiny Serial-to-Ethernet Device Server
In harsh industrial environments, the tDS-700 series (for i version) also adds 3000 VDC and +/- 4 kV ESD protection component that diverts the potentially damaging charge away from sensitive circuit to 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 that enables it to be easily installed anywhere, even directly attached to a serial device or embedded into a machine. The tDS-700 features a powerful 32-bit MCU that allows it to efficiently handle network traffic. The tDS-700 offers true IEEE 802.3af-compliant (classification, Class 1) Power-over- Ethernet (PoE) functionality using a standard category 5 Ethernet cable that allows it to receive power 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.

1.1 Ethernet Solutions
Nowadays, the Ethernet protocol has become the foremost standard for local area networks. Connectivity via the Internet snow common in many of the latest applications from home appliances, to vending machines, to testing equipment, to UPS, etc. An Ethernet network can link office automation and industrial control networks, access remote systems and share data and information between machines from multiple vendors, and also provides a cost-effective solution for industrial control networks.

1.2 VxComm Technology
In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another issue is that perhaps the existing the COM Port communication system was built many years ago and is now outdated.
As a result, a new technology, VxComm was developed to virtualize the COM Ports of the tDS-700 to allow up to 256 COM Ports to be used on a central computer. The VxComm driver saves time when accessing serial devices through the Ethernet without the need for reprogramming the COM Port software on the PC.

-9 - |
Tiny Serial-to-Ethernet Device Server
The 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 will be able to access your serial devices through the Ethernet in the same way as through a COM Port.

Tiny Serial-to-Ethernet Device Server
1.3 Web Server Technology
Web 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 the configuration of thetDS-700 via an Ethernet network without needing to install any other software tools, thereby reducing the learning curve required for maintaining the device.

PoE and Ethernet RJ-45 Jack
The tDS-700 series module is equipped with an RJ-45 jack that is used as the 10/100 Base-TX Ethernet port and features networking capabilities. When an Ethernet link is detected and an Ethernet packet is received, the Link/Act LED (Orange) indicator will be illuminated. When power is supplied via PoE (Power-over-Ethernet), the PoE LED (Green) indicator will be illuminated.
+12 to +48 VDC Jack
The tDS-700 series is equipped with a +12VDC to +48 VDC jack that can be used to connect a power supply. If no PoE switch is available on site, a DC adapter can be used to power the tDS-700 series module.

Operating Mode Switch
Run Mode: Firmware operation |
Init Mode: Configuration mode |
For tDS-700 series modules, the operating mode switch is set to the Run position by default. In order to update the firmware for the tDS-700 series module, the switch must be moved from the Run position to the Init position. The switch must be returned to the Run position after the update is complete.
LED Indicator
Once power is supplied to the tDS-700 series module, the system LED (S1) indicator will illuminate. An overview of the S1 LED functions is given below:

Serial COM Ports
The number of serial COM Ports available depends on the type of tDS-700 series module. For more detailed information regarding the pin assignments for the Serial COM ports, refer to Section 2.5 “Pin Assignments”.
DIN-Rail Mounting
The tDS-700 series modules include simple rail clips on the bottom of the chassis that allow them to be reliably mounted on a DIN-Rail or a wall. For more detailed information regarding DIN-Rail Mounting, refer to the illustration in figure below.

RS-422 Wiring
RS-485 Wiring
Notes:
1.Usually, you have to connect all signal grounds of RS-422/485 devices together to reduce common-mode voltage between devices.
2.Twisted-pair cable must be used for the DATA+/- wires.
3.Both two ends of the cable may require a termination resistor connected across the two wires (DATA+ and DATA-). Typically 120 Ω resisters are used.
4.The Data+ and B pins are positive-voltage pins, and Dataand A pins are negative-voltage pins in the above figure. The B/A pinsmay be defined in anotherway depending on devices, please check it first.
