1. Introduction
The tDS-700/DS-2200 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/DS-2200 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/DS-2200 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/DS-2200 meets the demands of virtually any network-enabled application.

In harsh industrial environments, the tDS-700/DS-2200 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/DS-2200 features a powerful 32-bit MCU that allows it to efficiently
handle network traffic. The tDS-700/DS-2200 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/DS-2200 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/
DS-2200 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 © 2020 ICP DAS CO., Ltd. All Rights Reserved. -11 -
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,
meaning that, with the assistance of tDS-700/DS-2200 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/DS-2200 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/DS-2200 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, supports PoE power supply. The DS-2200 series
module is equipped with two RJ-45 jacks that are used as the 10/100 Base-TX Ethernet port and
features networking capabilities, only ETH1 supports PoE power supply. 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. The DS-2200 series is equipped with a +12VDC to +48 VDC terminal 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/DS-2200 series module.
Operating Mode Switch
Run Mode: Firmware operation Init Mode: Configuration mode
For tDS-700/DS-2200 series modules, the operating mode switch is set to the Run position by
default. In order to update the firmware for the tDS-700/DS-2200 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.
