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

Features

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 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 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.

Tiny Serial-to-Ethernet Device Server

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

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.

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 Data- and A pins are negative-voltage pins in the

above figure. The B/A pins may be defined in another way depending on devices, please check it ﬁrst.

5. Typical Applications

This chapter provides some examples of typical scenarios for the tDS-700 module, including

applications focused on the Virtual COM, Direct Socket Connection, Ethernet I/O, Pair-connection

and TCP Client Mode, etc...

Tiny Serial-to-Ethernet Device Server

5.1 Virtual COM Application

The tDS-700 series is designed to link RS-232/422/485 devices to an Ethernet network. The

VxComm utility allows the built-in tDS-700 COM Port to be virtualized to a standard COM Port of a

host PC, as shown below:

In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC. Therefore, a

program originally designed for the MS-COMM standard can access the meter without the need for

any modification.

Tiny Serial-to-Ethernet Device Server

5.2 Direct Socket Connection Applications

tDS-700 series module can accept the TCP connection (include raw data) directly, it also can

communicate with TCP client and Serial Device in this way.

5.3 Ethernet I/O Applications

Linking to I-7000 series modules

The I-7000 series provides a variety of I/O operations, such as D/I, D/O, A/D, D/A, Counter and Frequency Measurement, etc. The I-7000 series was originally designed to be used with RS-485 networks, so the RS-485 of COM on the tDS-700 can be used to link to I-7000 series modules.

By using VxComm technology, programs that support serial devices on the host PC can be upgraded

from an RS-485 network to an Ethernet network without requiring any modifications to the

program.

Configurable Etherne t Da t a Logger

Using the VxComm driver, the tDS-700 +7000 modules can be virtualized

to become COM Port+7000 modules located on the host PC, and then the

Data Logger in the DCON Utility can be used to access data related to the

I-7000 from the Ethernet. Signal data originating from the I-7000 modules

can be analyzed using MS Excel without the need to write any custom

programs.

1: The DCON utility includes a log function, as show below:

Tiny Serial-to-Ethernet Device Server

2: Configure the system connection as shown below and click the “Start” button to begin logging

data.

3: Open the log file in MS Excel to view the log data as shown in the example below:

By using the I-7000 DCON utility and MS Excel in conjunction with VxComm technology, the signal

data originating from I-7000 modules via the Ethernet network can be analyzed without the need

to write custom programs. For more information about the log function, refer to the online help

feature (English and Traditional Chinese) of the DCON utility.

Tiny Serial-to-Ethernet Device Server

5.4 Pair-connection Applications

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, which is useful when

connecting mainframe computers, servers or other serial devices that do not themselves have

Ethernet capability.

Appendix A: Troubleshooting

A1. How do I restore the web password for the module to the factory default password?

The instructions below outline the procedure for resetting the web password to the factory default

value. Note: Be aware that ALL settings will be restored to the factory default values after the module is reset.

Step 1 Locate the Init/Run switch that can be found on

the right-hand side of the tDS-700 module and set it to

the "Init" position. Reboot the module to load factory

default settings including default web password.

Step 2 Execute either the VxComm Utility or the eSearch Utility to search for any tDS-700 modules

connected to the network. Verify that the tDS-700 has been reset to the original factory default

settings. For example, the module should be shown as having the default IP address, which is

192.168.255.1.

Tiny Serial-to-Ethernet Device Server

Step 3 Double-click the name of the module to open the Configure Server (UDP) dialog box, and

modify the basic settings as necessary, e.g., the IP, Mask and Gateway addresses, and then click the

"OK" button to save the new settings.

Step 4 Reset the Init/Run switch on the tDS-700 module to the

"Run" position and reboot the device.

Step 5 Log in to the web configuration pages for the tDS-700 module, using the default web

password, "admin".

Appendix B: Glossary

1. ARP (Address Re s olution Protocol)

The Address Resolution Protocol (ARP) is a telecommunication protocol that is used to convert an

IP address to a physical address, such as an Ethernet address.

Consider two machines A and B that share the same physical network. Each has an assigned IP

address IPA and IPB, and a MAC address, MACA and MACB. The goal is to devise a low-level software

application that hides the MAC addresses and allows higher-level programs to work only with the IP

addresses. Ultimately, however, communication must be carried out by the physical networks using

whatever MAC address scheme the hardware supplies.

Suppose machine a wants to send a packet to machine B across a physical network to which they

are both attached, but an only has the Internet address for B, IPB. The question arises: how does A

map that address to the MAC address for B, MACB?

ARP provides a method of dynamically mapping 32-bit IP address to the corresponding 48-bit MAC

address. The term dynamic is used since the mapping is performed automatically and is normally

not a concern for either the application user or the system administrator.

2. Clients and Servers

The client-server paradigm uses the direction of initiation to categorize whether a program is a

client or server. In general, an application that initiates peer-to-peer communication is called a

client. End users usually invoke client programs when they use network services.

By comparison, a server is any program that waits for incoming requests from a client program. The

server receives a request from a client, performs the necessary action sand returns the result to the

client.

Tiny Serial-to-Ethernet Device Server

3. Ethernet

The term Ethernet generally refers to a standard published in 1982 by Digital Equipment Corp., Intel

Corp. and Xerox Corp. Ethernet is the most popular physical layer Local Area Network (LAN)

technology in use today.

4. Firmware

Firmware is an embedded software program or set of instructions programmed on a device that

provides the necessary instructions for how the device communicated with other computer

hardware, and is located or stored in a semi-permanent storage area, e.g., ROM, EEPROM, or Flash

memory. Firmware can often be updated by downloading a file from the manufacturer’s web site

or FTP.

5. Gateway

Computers that interconnect two networks and pass packets from one to the other are called

Internet Gateways or Internet Routers. Gateways route packets that are based on the destination

network, rather than the destination host.

6. ICMP (Inte rnet Control Message Protocol)

ICMP provides a method of communicating between the Internet Protocol software on one

machine and the corresponding software on another. It allows a gateway to send error or control

messages to other gateways, or allows a host to diagnose problems with the network

communication.

7. Internet

Physically, the Internet is a collection of packet switching networks interconnected by gateways

that together with the TCP/IP protocol, allows them to perform logically as a single, large and

virtual network. The Internet recognizes hosts using 32-bit IP address.

Tiny Serial-to-Ethernet Device Server

8. IP (Int erne t Pr ot ocol ) Address

Each interface on the Internet must have a unique IP address (also called an Internet address).

These addresses are 32-bit numbers, and are normally written as four decimal numbers, one for

each byte of the address for example “192.168.41.1”. This is called dotted-decimal notation.

9. MAC (Media Access Control) Address

To allow a computer to determine which packets are meant for it, each device attached to an

Ethernet network is assigned a 48-bit integer known as its MAC address (also called the Ethernet

address, the hardware address or the physical address). A MAC address is normally written as eight

hexadecimal numbers, for example “00:71:88:af:12:3e:0f:01”. Ethernet hardware manufacturers

purchase blocks of MAC addresses and assign them in sequence as they manufacture Ethernet

interface hardware. Thus, no two hardware interfaces can have the same MAC address.

10. Packet

A packet is the unit of data sent across a physical network. It consists of a series of bits containing

data and control information, including the source and the destination node (host) address, and is

formatted for transmission from one node to another.

11. Ping

Ping is a network administration utility used to test the whether a host on an Internet network is

active, and to measure the round-trip time for messages sent from the originating host to a

destination computer. Ping operates by sending an ICMP echo request message to a host, expecting

an ICMP echo reply to be returned. Normally, if a host cannot be pinged, Telnet or FTP cannot be

used to connect to the host. Conversely, if Telnet or FTP cannot be used to connect to a host, Ping

is often the starting point to determine the nature of the problem.

12. RARP (Reverse Address Resolution Protocol)

RARP provides a method of dynamically mapping 48-bit MAC

address to the corresponding 32-bit IP address. RARP has now

been replaced by the Bootstrap Protocol (BOOTP) and the modern

Dynamic Host Configuration Protocol (DHCP).

Tiny Serial-to-Ethernet Device Server

13. Socket

Each TCP segment contains a source and destination port number that can be used to identify the

sending and receiving application. These two values, along with the source and destination IP

addresses in the IP header, uniquely identify each connection. The combination of an IP address

and a port number is called a socket.

14. Subnet Mask

A Subnet mask, often simply called the “Mask”, is a 32-bit number that masks and IP address, and

divides the IP address into the network address and the host address. Given its own IP address and

its subnet mask, a host can determine whether a TCP/IP packet is destined for a host that is (1) on

its own subnet, or (2) on a different network. If (1), the packet will be delivered directly; otherwise

it, will be delivered via a gateway or a router.

15. TCP (Tr a ns m iss ion Control Protocol)

TCP is a set of rules used in combination with the Internet Protocol to send data in the form of

message units between computers over the Internet. TCP provides a reliable flow of data between

two hosts and is associated with tasks such as dividing the data passed to it from an application into

appropriately sized chunks for the network layer below, acknowledging received packets, setting

timeouts to make certain that the other end acknowledges packets that are sent, and so on.

16. TCP/IP

The Transmission Control Protocol (TCP) and the Internet Protocol (IP) is standard network

protocols that are almost always implemented and used together in a formation are known as

TCP/IP. TCP/IP can be used to communicate across any set of interconnected networks.

17. UDP (Use r Da t a gra m Prot oc ol)

UDP is an internet protocol that provides a much simpler service to the application layer as it only

sends packets of data from one host to another, but there is no guarantee that the packets will

reach the destination host. UDP is suitable for purposes where error checking and correction is

either not necessary or is performed in the application.
