1. Introduction

SE5001, the Ethernet Serial device server is a gateway between Ethernet (TCP/UDP) and RS-232/RS-422/RS-485 communications. The information transmitted by SE5001 is transparent to both host computers (Ethernet) and serial devices (RS-232/RS-422/RS-485). Data coming from the Ethernet is sent to the designated RS-232/RS-422/RS-485 port and data received from RS-232/RS-422/RS-485 port is sent to the Ethernet transparently allowing bidirectional communication.

In the computer-aided manufacturing or industrial automation areas, SE5001 is used by field devices to directly connect to an Ethernet network. The user can then use a network application or use the Virtual COM software to simulate a virtual com port in the PC to fetch serial data from SE5001 remotely over the Ethernet.

With SE5001, it is possible to communicate with a remote serial device in the LAN or even in the Internet, which increases the communication distance and scalability dramatically.

1.3 Application Connectivity

TCP Server Mode：SE5001 can be configured as a TCP server in TCP/IP Network to listen for an incoming

TCP client connection to the serial device. After the connection is established between the serial device server and the host computer, data can be transmitted in both directions. This also applies to Virtual COM running in the server mode.

Figure 1.1 TCP Server Mode

TCP Client Mode：SE5001 can be configured as a TCP client in TCP/IP Network to establish a connection with

a TCP server in the host computer. After the connection is established, data can be transmitted between serial device and host computer in both directions. This also applies to Virtual COM running in the client mode.

User Manual Version 1.7 SE5001 Serial Device Server

Figure 1.2 TCP Client Mode

UDP Mode：UDP is a faster but connectionless network protocol. It does not guarantee the delivery of network

datagrams. SE5001 can be configured to transfer data using unicast or multicast UDP from the serial device to one or multiple host computers. Data can be transmitted between serial device and host computer in both directions.

2. Press the reset button on SE5001 to reset the settings back to the default value

Figure 2.1 SE5001 Interfaces

2.1 Installation Procedure

Step 1: Connect SE5001 to a power source using its 5V DC Jack or its 9-30V DC Terminal Block. Note that

the DC Jack is 5V only and should be used with a power adaptor.

Note：SE5001 provides two power inputs that can be connected simultaneously to different DC power sources. If any of the power inputs fail, the other power source can act as a backup

to support the power needs automatically. The redundant dual DC power inputs give one extra assurance of non-stop operation.

Step 2: Connect SE5001 to the Ethernet network. Use a standard straight-through Ethernet cable when

connecting to a hub/switch. To simply the setup, a cross-over Ethernet cable can be used to connect the serial device server to a PC directly. Please make sure that the PC is in the same network subnet as SE5001.

Step 3: Connect SE5001’s serial port to a serial device. Step 4: Placement options: Mount SE5001 to a wall/panel (Mounting screws included) or Din-Rail rack

(optional Din-Rail-Kit DK-25).

24

emptied. If this option is disabled, SE5001 will keep old serial data when the connection is broken (Figure 3.16).

3.2.12. Setting Packet Delimiter

Packet delimiter is a way of packaging serial data. It can prevent serial data from being truncated by packing them in the same Ethernet packet. SE5001 provides two kinds of packet delimiter: Timer and Character. The default timer is 2 ms (0ms to disable this function). This means that if SE5001 does not receive new serial data within 2ms, it will send out all the serial data in buffer in one packet over Ethernet. The way to change the delimiter timer is shown in the following figure (Figure 3.17):

Figure 3.17 Setting packet delimiter timer

Another kind is character delimiter. If the character delimiter is set to 0x0d, this means SE5001 will send out all the serial data in buffer in one packet over Ethernet only if it reads 0x0d. The following figure shows how to configure character delimiter: (Figure 3.18)

This backup function could recover settings from the Flash to the EEPROM if the settings in the EEPROM are lost. If SE5001 detects that there is an EEPROM backup in the flash. It will compare the backup values in the Flash and EEPROM. If the values do not match, it will write the backup settings in the Flash to the EEPROM. To enable this function, follow Figure 3.24 in the Security Settings.

 Click on Backup EEPROM to back up the settings from the EEPROM to the Flash. SE5001 would then

show Have Backup.

 Click on Erase Backup to erase the settings stored in the Flash. SE5001 would then show No Backup.

3.3.5. Link Mode Configuration

User Manual Version 1.7 SE5001 Serial Device Server

31

SE5001 supports different Link Modes, which are TCP Server, TCP Client, and UDP (Figure 3.25). Under the three Link Modes, TCP Server can support Virtual COM, Pair Connection, or Reverse Telnet applications. TCP Client can support Virtual COM or Pair Connection application. If none of the application is enabled, the SE5001 will run in RAW mode. In the upcoming sections, we will discuss how to setup different Link Modes properly.

Figure 3.25 Link Modes

3.3.6. Link Mode: Configure SE5001 as a TCP Server

SE5001 defaults in TCP Server mode, there are additional connection settings that can be configured (Figure 3.26). By selecting the TCP Server mode, a TCP Client program should be prepared to connect to SE5001.

 Click on the “COM1” link on the left hand side.  Select TCP Server. TCP Server is the default link mode.  Enter the Local Listening Port. This is the port specified in the TCP Client program connecting to the

serial device server. The default local port is 4660.

 IP Filter: Only the designated IP address will be able to access the COM port if this option is enabled. This

option is disabled by default.

 TCP Keep-Alive: Specify the interval in the “Idle Time Before Sending TCP Alive Packet” to force

SE5001 to send TCP Keep-Alive packets in the set interval to prevent disconnection from the client. Note that this field has a multiplier of 10, so the default value 4 means to send Keep-Alive packets every 40 seconds.

 TCP Inactivity Timeout: Specify the value in “TCP Inactivity Time Before Disconnect” to force SE5001

actively close a TCP connection after some specific inactivity time (no packets). The default value is 0, which means the SE5001 would never close an established connection.

 Scroll to the bottom of the page and click on “Save Configuration” button to save the changes.  Go to the Application Configuration section starting from 3.3.9 to apply Virtual COM, Pair Connection, or

Reverse Telnet application if applicable. Otherwise go to the COM Configuration (section 3.3.19) for serial settings directly.

Figure 3.26 TCP Server Setup Note: LINK1 is associated with COM1; LINK2 is associated with COM2, and so on.

3.3.7. LINK Mode: Configure SE5001 as a TCP Client

By selecting the TCP Client mode, it means that a TCP Server program should be prepared to connect to SE5001. Figure 3.27 shows all the settings provided for the TCP Client.

 Click on the “COM1” link on the left hand side.  Select TCP Client.  Enter the preferred Destination IP and Port. This should match the IP settings of the TCP Server

program.

 Connect Rule: Decide how SE5001 should connect to the TCP Server here. If SE5001 should always

keep the connection, select TCP Connect on Power-on. This means SE5001 would connect to the TCP Server program when SE5001 is powered on. By default, TCP Connect on Any Serial Character is selected. This means that SE5001 would only connect to the TCP Server program when it receives data from its serial interface. If TCP Connect on Any Serial Character is selected, there are two additional options to change, which are Serial Inactivity Time Before Disconnect and Waiting Time Between Re-connect Attempts. Serial Inactivity Time Before Disconnect determines how long SE5001 should wait before closing a TCP connection if there is no incoming serial data. The default value is 40 seconds. Waiting Time Between Re-connect Attempts determines the time SE5001 should wait before it tries to establish a connection with a TCP Server again if it fails to connect to the TCP Server. The default value is

User Manual Version 1.7 SE5001 Serial Device Server

33

1 minute.

 TCP Keep-Alive: Specify the interval in the “Idle Time Before Sending TCP Alive Packet” to force

SE5001 to send TCP Keep-Alive packets in the set interval to prevent disconnection from the client. Note that this field has a multiplier of 10, so the default value 4 means to send Keep-Alive packets every 40 seconds.

 TCP Inactivity Timeout: Specify the value in “TCP Inactivity Time Before Disconnect” to force SE5001

actively close a TCP connection after some specific inactivity time (no packets). The default value is 0, which means the SE5001 would never close an established connection.

3.3.8. Link Mode: Configure SE5001 in UDP

SE5001 also supports connectionless UDP protocol compared to the connection-oriented TCP protocol. Please be aware that even though UDP provides better efficiency in terms of response time and resource usage, it does not guarantee data delivery. It is recommended to utilize UDP only with cyclic polling protocols where each request is repeated and independent, such as Modbus Protocol. Figure 3.28 shows the UDP settings.

 Click on the “COM1” link on the left hand side.  Select UDP.  Destination IP and Port: Specify the Begin and End IP here. Four groups of range IPs are allowed. This

is the IP address of the UDP program and the Port it is listening to. Note that the maximum number of UDP nodes that SE5001 can handle would highly depend on the traffic load. We have tested that SE5001 can handle up to 32 UDP nodes (baud rate 9600 bps, request interval 100ms, and data length 30bytes).

 Enter the Local Listening Port. This is the port that SE5001 should listen to. Match this setting in the UDP

program (usually called destination port in the UDP program).

 Scroll to the bottom of the page and click on “Save Configuration” button to save the changes.  Go to the section 3.3.16 to apply Pair Connection application if applicable. Otherwise go to the COM

Configuration (section 3.3.19) for serial settings directly.

Figure 3.28 UDP Setup

3.3.9. TCP Server Application: Enable Virtual COM

SE5001 will encapsulate control packets on top of the real data when Virtual COM is enabled. This will allow the Virtual COM port in the Windows/Linux system to access SE5001’s COM ports. The benefit of using Virtual COM is that rewriting an existing COM program to read IP packets is unnecessary. In other words, it is possible to use an ordinary serial (COM) program. The conversion/virtualization of IP to COM is all done in the system driver transparently. Figure 3.29 shows SE5001 in TCP Server mode with Virtual COM enabled.

 Follow section 3.2.5 to configure SE5001 in TCP Server mode properly.  Check Enable VirtualCOM for Serial/IP to enabled Virtual COM application in SE5001.  Check Enable VirtualCOM Authentication (Note: An empty password will fail to authenticate) to lock

up Virtual COM access with SE5001’s login password.

 Scroll to the bottom of the page and click on “Save Configuration” button to save the changes.  Configure Virtual COM in the Operating System. For Windows, refer to 4. Using Virtual COM. Remember

SE5001’s IP address and the Local Listening Port here in order to enter this information in Serial/IP Virtual COM’s Control Panel later.

3.3.10. TCP Server Application: Enable RFC 2217

The underlying protocol of Virtual COM is based on RFC 2217, the Telnet COM Control Option. Therefore, it is possible to use RFC 2217 with SE5001 in the TCP Server mode. To do so, refer to section 3.3.9 to enable Virtual COM, so that SE5001 becomes aware of the commands. Note that there is no need to configure Virtual COM on the Operating System because Virtual COM ports would not be used.

3.3.11. TCP Client Application: Enable Virtual COM

It is also possible to run Virtual COM in TCP Client mode (Figure 3.30). It is usually easier to use Virtual COM in the Client mode if SE5001 uses dynamic IP (DHCP) because setting a static IP address in Virtual COM’s Control Panel

User Manual Version 1.7 SE5001 Serial Device Server

36

is not possible.

3.3.13. TCP Server Application: Configure SE5001 as a Pair Connection Master

Pair Connection is useful when pairing up two serial devices over the Ethernet or when it is impossible to install Virtual COM in the serial device. Pair connection does require two SE5001s to work in pair, one would be the Pair Connection Master (Error! Reference source not found.) and the other would be the Pair Connection Slave.

Figure 3.31 TCP Server with Pair Connection Enabled

 Follow section 3.2.5 to configure SE5001 in TCP Server mode properly.  Check Enable Pair Connection to enabled Pair Connection application in SE5001.  Scroll to the bottom of the page and click on “Save Configuration” button to save the changes.

 Go to the Pair Connection Slave Setup below (section 3.3.14). Remember SE5001’s IP address and the

Local Listening Port here in order to enter this information in the Pair Connection Slave later.

3.3.14. TCP Client Application: Configure SE5001 as a Pair Connection Slave

A Pair Connection Slave (Figure 3.32) needs to pair up with a Pair Connection Master. Please setup a Pair Connection Master first before proceeding.

 Match the Destination IP and Port here with the settings of Pair Connection Master’s IP and Listening

Port setup previously.

3.3.15. TCP Server Application: Enable Reverse Telnet

Reverse Telnet application is useful if a telnet program is used to connect to SE5001 and the serial interface of the SE5001 is connected to a Terminal Server. Telnet programs in Windows / Linux usually require special handshaking to get the outputs and formatting show properly. SE5001 will interact with those special commands (CR/LF commands) if Reverse Telnet is enabled.

User Manual Version 1.7 SE5001 Serial Device Server

3.3.16. UDP Application: Multi-Point Pair Connection

It is also possible to setup pair connection in UDP mode to have more than one Pair Connection Master or Slave to communicate to each other. For example, it is possible to setup one Modbus Master and six Modbus Slaves in UDP (Figure 3.34). Note again that UDP does not guarantee data delivery and only data would be transmitted over Ethernet; other serial pings are not transmitted. If RS-232 along with flow control, it is recommended to use Multi-Point Pair Connection in TCP (section 3.3.18).

 Note that the Destination IP and Port of the Slaves need to be equal to the Master’s IP and Port. Local

Listening Port of the Slaves needs to be equal to the Master’s Destination Port.

3.3.17. TCP Server Application: Multiple TCP Connections

To have more than one TCP Client connecting to SE5001 in TCP Server mode, contact Atop Technical Support to obtain a special multi-connection version firmware. After the firmware is uploaded to SE5001, the WebUI will have one additional option called “Multiple_Connections” (Figure 3.35). The Multi-Connection option will allow up to a maximum of four TCP Client connections. SE5001 will broadcast serial data to all connected TCP Clients. Note that it is also possible to use this multi-connection feature in conjunction with other TCP Server applications, such as Virtual COM, Pair Connection, and Reverse Telnet. For example, enabling multi-connection along with Pair connection will result in Multi-Point Pair Connection in TCP mode (section 3.3.18).

User Manual Version 1.7 SE5001 Serial Device Server

41

Figure 3.35 TCP Server with Multiple Connections Enabled

3.3.18. TCP Server Application: Multi-Point TCP Pair Connections

The difference between Multi-Point TCP Pair Connection and Multi-Point UDP Pair Connection is that the TCP implementation would also exchange flow controls pins of RS-232. However, the TCP Server is limited to a maximum of four connections. If there are than four serial devices and does not use flow control pins with RS-232 or RS-485, it is possible to setup pair connection in UDP mode (section 3.3.16). After multi-connection is enabled in the WebUI, refer to the following table to setup Pair Connection as in Figure 3.36.

Flow Control:

User Manual Version 1.7 SE5001 Serial Device Server

43

Choose between No Flow Control, RTS/CTS (Hardware Flow Control), DTR/DSR, Xon/Xoff (Software Flow Control). If Xon/Xoff is selected, Xon and Xoff characters are changeable. Defaults are 0x11 for Xon and 0x13 for Xoff. If the serial device uses Xon/Xoff in conjunction with DTR/DSR, enable Controlling DTR to simulate

receiving Xon/Xoff and reading DSR to get Xon/Xoff currently.

Empty Serial Buffer When TCP Connection is Established:

By default, SE5001 will empty its serial buffer when a new TCP connection is established. This means that the TCP application will not receive buffered serial data during a TCP link breakage. To keep the serial data when there is no TCP connection and send out the buffered serial data immediately after a TCP connection is established, set this option to No.

Data Packet Delimiter:

Packet delimiter is a way of packing data in the serial communication. It is designed to keep packets in track. SE5001 provides two types of delimiter: Time Delimiter and Character Delimiter.

 Time Delimiter: SE5001 will transmit the serial data in its buffer when the specified time interval has

reached and no more serial data comes in. The default time is 2ms, which means SE5001 will push out its serial buffer if it does not receive any serial data with in 2ms.

 Character Delimiter: SE5001 will transmit the serial data in its buffer when it sees the specified character.

The default character delimiter is 0x0d, which means SE5001 will push out its serial buffer if it sees 0x0d (carriage return) in the serial data.

COM Type Selection:

Select between RS-232, RS-422, and RS-485. Note that RS-485 refers to 2-Wire RS-485 and RS-422 is compatible with 4-Wire RS-485.

5. Writing a TCP Program

Before working on the sample TCP program, please make sure the serial device server is properly configured to the TCP server mode. The sample program is a TCP Client that connects to the serial device server.

5.1 Running the Sample Program

Sample programs written in Microsoft Visual Basic 6 and Visual C++ 6 are included in the CD with their source codes. Find them inside \sample\vb_ap\ and \sample\vc_ap respectively.

5.1.1 TCPTEST in Microsoft Visual Basic 6

This sample program is written in Visual Basic 6.0 with Winsock Controls. It demonstrates how to send and receive data from a PC to SE5001 via Ethernet using two TCP sockets.

Open the project file by double clicking tcptest.vbp or open it in Visual Basic (Figure 5.1). Press the Start button to launch TCPtest in debug mode.

Figure 5.1 TCP Test Sample Program in Visual Basic

It is also possible to launch the precompiled program (Figure 5.2) without installing Visual Basic, double click on Tcptest.exe to launch. Make sure Visual Basic 6 Runtime is installed.

Service Pack 6 for Visual Basic 6.0: Run-Time Redistribution Pack from Microsoft:

6. Diagnostics

There are several ways to can check the status and availability of the serial device server.

6.1 Use Standard Ping Command

From the Windows Start menu, select Run and type in “ping <TCP Server IP address>”. If the serial device server can receive ping requests sent from the host, it will reply to the ping message (Figure

6.1). If the ping request cannot reach the serial device server, timed out message will show (Figure 6.2).

Figure 6.1 Successful Ping Reply

Figure 6.2 Ping Command Failed

User Manual Version 1.7 SE5001 Serial Device Server

68

6.2 Use Device Management Utility

Use Device Management configuration utility that comes with the product CD or download from Atop website to check on the status of the serial device server. The status and version can be read from the tool. For example, ‘S’ means that COM1 is in TCP Server mode and is not connected to a TCP Client (Figure 6.3). ‘A’ means that COM1 is in server mode and is connected to a TCP Client.

Figure 6.3 Device Management Utility

6.3 Use TCPTEST.exe or TCPTEST2.exe Sample Program

Use sample programs TCPTEST.exe and TCPTEST2.exe that comes with the product CD to check the status of the serial device server. Please refer to chapter 5. Writing a TCP Program.
