Introduction
The tDS-700 is a series of Serial-to-Ethernet device servers 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 communication. 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 software modification.

The VxComm Driver/Utility supports the most popular operating
system in the world, including 32-bit and 64-bit Windows
7/Vista/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 modules. In addition, the utility
contains a built-in terminal program, so users can send/receive
command/data via the terminal program for easy testing.
The tDS-700 device servers can be used to create a
pair-connection application (as well as serial-bridge or
serial-tunnel), and can then route data over TCP/IP between two
serial devices, which 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.
DHCP minimizes configuration errors caused by manual IP address
configuration, such as address conflicts caused by the assignment
of an IP address to more than one computer or device at the same
time. The tDS-700 supports the DHCP client function, which allows
the tDS-700 to easily obtain the necessary TCP/IP configuration
information from a DHCP server. The tDS-700 also contains a
UDP responder that transmits its IP address information in
response to a UDP search from the VxComm Utility, making local
management more efficient.
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.
Based on an amazing tiny form-factor, the tDS-700 achieves the maximum space savings that allows it to be easily installed anywhere,
even directly attached to a serial device or embedded into a machine.
The tDS-700 series also contains a built-in CPU watchdog, which automatically resets the CPU if the built-in firmware is operating
abnormally, or if there is no communication between the tDS-700 and the host for a predefined period of time (system timeout). This
is an important feature that ensures the tDS-700 operates continuously, even in harsh environments.

Introduction
Modbus has become a de facto standard industrial communication protocol, and is now the most commonly available means of
connecting industrial electronic devices. Modbus allows for communication between many devices connected to the same RS-485
network, for example, a system that measures temperature and humidity and communicates the results to a computer. Modbus is
often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA)
systems.

The tGW-700 module is a Modbus TCP to RTU/ASCII gateway that enables a Modbus/TCP host to communicate with serial Modbus
RTU/ASCII devices through an Ethernet network, and eliminates the cable length limitation of legacy serial communication devices.
The module can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel application), and can then
route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting mainframe computers,
servers or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability.
DHCP minimizes configuration errors caused by manual IP
address configuration, such as address conflicts caused by the
assignment of an IP address to more than one computer or
device at the same time. The tGW-700 module supports the
DHCP client function, which allows it to easily obtain the
necessary TCP/IP configuration information from a DHCP server.
The module also contains a UDP responder that transmits its IP
address information in response to a UDP search from the
eSearch utility, making local management more efficient.
The tGW-700 module features a powerful 32-bit MCU to enable
efficient handling of network traffic, and also has a built-in web
server that provides an intuitive web management interface
that allows users to modify the configuration of the module,
including the DHCP/Static IP, the gateway/mask settings and
the serial port settings.
The module contains a dual watchdog, including a CPU watchdog (for hardware functions) and a host watchdog (for software
functions). The CPU watchdog automatically resets the CPU if the built-in firmware is operating abnormally, while the host watchdog
automatically resets the CPU if there is no communication between the module and the host (PC or PLC) for a predefined period of
time (system timeout). The dual watchdog is an important feature that ensures the module operates continuously, even in harsh
environments.
