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 2500 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 tDS-
700 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 is now 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.

Tiny Serial-to-Ethernet Device Server
Copyright © 2016 ICP DAS CO., Ltd. All Rights Reserved. -9 -
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.

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 the tDS-700 via an Ethernet network without needing to install any other software
tools, thereby reducing the learning curve required for maintaining the device.

Run Mode: Firmware operation 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.

+12 to +48 VDC Jack:
The tDS-700 is equipped with a +12 VDC 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 module.
6.
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-
