2 Introduction

2.1 Product Overview

Many industrial and Commercial devices equipped with slow serial communication ports—RS-232, RS-485, and RS-422—are limited by transmission distance of 15 m. Examples of these devices are PLC controllers, card readers, display signs, security controls, CNC controller, etc. ATOP Technologies has overcome this limit with our new family of SE5416A Series Serial Device Servers. SE5416A Series is designed to transmit data between one-or-more serial devices and one-or-more TCP/IP devices through Ethernet or the optional modem, and hence enhance the accessibility of the serial device through the ubiquitous TCP/IP based Ethernet.

2.2 Features

Dual 10/100Mbps Fast Ethernet for redundancy with full duplex auto negotiation Support RAW TCP Server/ TCP Client / UDP / Virtual COM / Tunneling Modes Configuration: Built-in Web Server /Serial Console/ Telnet / Windows-based Utility Monitor, manage and control industrial field devices remotely
Caution
Beginning from here there will be extreme caution exercised.
Never install or work on electrical or cabling during periods of lighting activity. Never

5.1 Administrator Login

As soon as the device is connected on the LAN, the user can proceed to navigate through its configuration using Serial Manager© (utility that comes in the CD); as noted in Figure 5.1 below, important information such as the IP, MAC address, etc. is going to be displayed.
To access the device’s Web UI click on the Config by browser icon, the web browser will open and prompt you to enter username and password (see Factory Default Settings for more information), proceed then to click “OK” or press Enter. Alternatively, enter the IP address of the device in the URL bar of the browser.
Note: Be sure your PC Is located in the same network sub-net as SE5416A Series.

5.3 Network Configuration

Figure 5.7
Click on the “Network” link to open network settings.
LAN / Bridge Settings, when the bridge function is enabled, LAN1 and LAN2 will use
the same IP address for redundancy. Therefore, LAN1 Settings will become Bridge Settings and LAN2 Settings will be disabled. When the bridge function is disabled, you can LAN1 and LAN2 can be in different subnets. Fill in Bridge / LAN settings accordingly. Alternatively, you may activate DHCP (Dynamic Host Configuration Protocol) client
function by checking on “Obtain an IP automatically” field to obtain IP address, gateway
and subnet mask, and DNS from a DHCP server automatically.
28
Figure 5.8
DNS Settings, Fill in DNS (Domain Name System) information in order to have an
external DNS server resolve domain name into IP address. This is crucial if the NTP and SMTP services use domain names instead of IP addresses. A DNS server will be retrieved from the DHCP server automatically if DHCP is enabled.
Figure 5.9
29
SNMP Settings, The SNMP function is disabled by default. To enable this function check
on “Enable SNMP” option. Basic SNMP configurations such as Read/Write Community,
SysName (System Name), SysLocation (System Location), and SysContact (System Contact) are supported. In addition, you can send SNMP Trap events to a SNMP Trap server by entering its IP address. The changes will become effective immediately after a successful save.
Figure 5.10
ERPS Settings, A typical ring topology provides multipoint connectivity economically, but
the network traffic will loop inside the ring without a proper protection mechanism. Ethernet Ring Protection Switching (ERPS) is a protocol for Ethernet layer ring networks. ERPS provides highly reliable and stable protection in the ring topology while not forming network loops that could potentially affect the network operation. In a the Ring topology, each Ring Node is connected to an adjacent Ring Node participating in the same Ring using two independent links (i.e. two ways). Loops can be avoided by guaranteeing that traffic may flow on all but one of the ring links at any given time. This particular link is called Ring Protection Link (RPL). A control message called R-APS coordinates the activities of switching on/off the RPL. Under normal conditions, this link is blocked by the Owner Node, which is referred as the blocking state. In case of a network failure, the RPL Owner node will be responsible to unblock the RPL to allow it to be used for forwarding, hence called the protection state. Therefore, the RPL becomes the backup link when a link failure occurs. The following table describes the functions of different ERPS settings.

Description
Spanning Tree
Choose whether to enable or disable Spanning tree.
Force Version
Select STP or RSTP.
Priority
Configures the bridge priority in the range of 0 ~ 61440. The switch with lower bridge priority has more chance to become a root bridge.
Maximum Age
If a device is not the root and it does not receive a hello message in within the “Maximum Age”, it will reconfigure itself as a root, ranges from 6 to 40 seconds.
Hello Time
The amount of time that the root should wait before sending hello messages again, ranges from 1 to 10 seconds.
Forward Delay
Configures the amount of time the device should wait before checking to see if it should change from the learning state to the forwarding state. Lesser delay time means that the state will change more quickly, ranges from 4 to 30 seconds.
Port Path Cost
Configures the port path cost in the range of 1~200000000. This value will affect the combination path cost. The lowest combination path cost will be the best path to the Root Bridge
Port Priority
Configures the port priority in the range of 0~240. The port with the lowest priority value has the best route to the root bridge.
Port P2P
Selects P2P (point to point) connection type:
Force No: Force Port P2P link false.  Force Yes: Force Port P2P link to true. Auto: Set Port P2P link to auto detection.

Choose whether the port is an edge connection.
by bridges/switches to every port, the bridges/switches will repeatedly rebroadcast the broadcast messages, and this can flood the network. STP creates a spanning tree and disables those redundant links that are on the same level of the tree, which leaves only a single active path between any two nodes. This function avoids flooding and increases network efficiency. RSTP (Rapid Spanning Tree Protocol) are also supported. It is an evolution of the STP. It has a slightly changed topology, which helps to provide a much faster spanning tree convergence. The following table explains each STP option’s usage.

TCP
TCP Timeout, Specify the value in “TCP Timeout” to force SE5416A Series actively
close a TCP connection after some specific inactivity time (no packets). The default value for it is 3600 seconds. Disabling this option means SE5416A Series would never actively close an established connection.
Delimiters
Serial to Network Packet Delimiter, Packet delimiter is a way of packing data in the
serial communication. It is designed to keep packets in track. SE5416A Series provides three types of delimiter: Time Delimiter, Maximum Bytes and Character Delimiter. Note that the following delimiters (Interval, Max Byte and Character) are programmed in the OR logic. Meaning that if any of the three conditions were met, SE5416A Series would
37
Attention
Interval Timeout Manual Calculation
The optimal “Interval timeout” depends on the application, but it must be at least larger
than one character interval within the specified baud rate. For example, assuming that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is (10 (bits)/1200 (bits/s))*1000 (ms/s) = 8.3 ms.
Therefore, you should set the “Interval timeout” to be larger than 8.3 ms. Rounding 8.3
ms to the next integer would get you 9 ms.
transmit the serial data in its buffer over the network.
Interval timeout, SE5416A Series will transmit the serial data in its buffer when the
specified time interval has reached and no more serial data comes in. The default value is calculated automatically based on the baud rate. If the automatic value results in chopped data, the timeout could be increased manually by switching to
“Manual setting” and specifying a larger value. If the bytes do not reach certain
length condition, the bytes could be discard to avoid devices connect on the TCP side running into issues. To do this, enable “Discard Byte”, then select the condition (>, <, =, !=) you want and the length desired.
Max Byte, SE5416A Series will transmit the serial data in its buffer when the
specified length has reached. Enable this option if you would like SE5416A Series to queue the data until it reaches a specific length. This option is disabled by default.
Character, SE5416A Series will transmit the serial data in its buffer when it sees
the incoming data include the specified character (in HEX format). This field allows one or two characters. If character delimiter is set to 0x0d, SE5416A Series will push out its serial buffer when it sees 0x0d (carriage return) in the serial data. This option is disabled by default.
Network to Serial Packet Delimiter, Same as the delimiters above, but controls data
flow in the opposite direction. It will store data from the network interface in the queue and send it over to the serial interface until one of the delimiter conditions is met.
Character Send Interval, This option specifies the time gap between each character.
When set to two seconds, SE5416A Series will split the data in the queue and only transmit one character (byte) every two seconds; this option is disabled by default.
Response Interval Timeout, This option only affects the Request & Response Mode
38
and has no effect on the Transparent Mode. When TCP data is received (request) and passed to Serial side, the device will wait for the set time before transferring another TCP data if the Serial side did not receive any data (response).
Serial
Serial FIFO, By default, SE5416A Series has its FIFO function enabled to optimize its
serial performance. In some applications (particularly when the flow control is enabled), it may deem necessary to disable the FIFO function to minimize the amount of data that is transmitted through the serial interface after a flow off event is triggered to reduce the possibility of overloading the buffer inside the serial device. Please note that disabling this option on baud rates higher than 115200bps would reduce the data integrity noticeably.
Serial Buffer, By default, SE5416A Series 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, disable this option.

5.5 Alert Settings

Click on the “Alert” link to open its submenu and E-mail settings.
Figure 5.17

5.5.1 Email Settings

In case the device raises an alert and/or warning message, it will send an email to the administrator’s mailbox. Email Settings allows you to set up the device to be able to send an email. To set up the email sending, you need to put a “Sender” email address which will be the “From” on the email. Then, you fill in “Receiver” email address to which the email is sent. You can send the email to several recipients using Semicolon (;) to separate each email address. Next step is to set the Email Server. First, you fill in the IP address of a Mail Server in your local network. If the Mail Server needs a user authentication, you need to enable “SMTP server authentication required”, and fill in Username and Password. Please contact your network administrator for Mail Server IP address and the Username and
Password,
Note: You can click on the “Send test Mail” button to verify your mail settings.

7 Link Modes and Applications

7.1 Link Mode Configuration

SE5416A Series supports different Link Modes, which are TCP Server, TCP Client, and UDP. Under the three Link Modes, TCP Server can support RAW, Virtual COM, or Reverse Telnet applications. TCP Client can support Virtual COM application. In the upcoming sections, we will discuss how to setup different Link Modes properly.
71

7.1.1 TCP Server Mode

SE5416A Series can be configured as a TCP server in a TCP/IP Network to listen for an incoming TCP client connection to a 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 whenever the VCOM is running on server mode. Please be reminded that this is the device’s default link mode.
Figure 7.1
SE5416A Series defaults in TCP Server mode, there are additional connection settings that can be configured, Figure 7.2. By selecting the TCP Server mode, a TCP Client program should be prepared to connect to SE5416A Series.
72
Figure 7.2
For setting as a TCP Server, please follow these steps.
Click on the COMX link under Serial on the left hand side.  Select TCP Server in the Link Modes; TCP Server is the default link mode. Also in this
section you will find the following options.
Mode, there are 3 different communication modes here:
RAW, there is no protocol on this mode, meaning the data is passed
transparently.
Virtual COM, the Virtual COM protocol is enabled on the device to
communicate with a virtualized port from the client. It is possible to create a Virtual COM port on Windows/Linux in order to communicate with the device as a Client.
Reverse Telnet, used to connect the device and another serial device
(usually a Terminal Server) with a Telnet program. Telnet programs in Windows / Linux usually require special handshaking to get the outputs and formatting show properly. The SE5416A Series will interact with those special commands (CR/LF commands) once Reverse Telnet is enabled.
Enter the Local Port, this option specifies the port number that the server should listen to;
it is used by the client to connect to the server. Default local port is 4660.
Go to Response Behavior for more information on this setting. For serial settings, go to
73
Sec. 5.4.1. For Advanced settings, go to Sec. 5.4.2.
Scroll to the bottom of the page and click on “Save Configuration” button to save the
changes.
Other important variables to consider are: IP Filter, enables the Source IP option below to block an IP address from accessing the
COM port.
Source IP, specifies the device’s Source IP which will be transmitting data to our Server.
In other words, our Server will only allow data from this IP to flow (hence its own name implies Source IP); only one source is allowed.
Maximum Connection, the number of devices/clients (max. of 4 clients), to be served is
set in this section.
Response Behavior, in which we will have as options:
Request & Response Mode, it determines how the device will proceed when it
receives requests from connected hosts. Under this mode, the port will hold requests from all other connected hosts until the serial device replies or the Response Interval timeout takes into effect to discard it; however, unrequested data sent from the serial device would be forwarded to all connected hosts.
Reply to requester only, the port will reply to the connected host who
requested the data only.
Reply to all, a reply is sent to all connected hosts.
Transparent mode, the port will forward requests from all connected hosts to the
serial device immediately and reply to all connected hosts once it receives data from the serial device.
Note: LINK1 is associated with COM1; LINK2 is associated with COM2, and so on.
74

7.1.2 TCP Client Mode

SE5416A Series 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 a serial device and a host computer in both directions; this also applies to Virtual COM running in the client mode.
Figure 7.3
By selecting the TCP Client mode, it means that a TCP Server program should be prepared to connect to SE5416A Series; Figure 7.4 shows all the settings provided for the TCP Client.
75
Figure 7.4
For setting as a TCP Client, please follow these steps.
Click on the COMX port under Serial on the left hand side.  Select TCP Client in the Link modes.  Only two communication modes are available here: RAW and Virtual COM which
definitions are the same as above in Mode.
Enter the preferred Destination IP and Port. This should match the IP settings of the
TCP Server program.
Enable and enter Destination IP 2 and Port 2 if necessary. Two different servers can be
set here (for redundancy), the second server has to be enabled by ticking the box.
Go to Response Behavior for more information on this setting. For serial settings, go to
Sec. 5.4.1. For Advanced settings, go to Sec. 5.4.2.
Scroll to the bottom and click on “Save Configuration” button to save the changes.
76

7.1.3 UDP Mode

UDP is a faster but connectionless network protocol; it does not guarantee the delivery of network datagram. The SE5416A Series 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. There is no server or client concept on this protocol, they are called peers or nodes. So here you only need to specify the Local Port that we should listen to and specify the Destination IPs of the remote UDP nodes.
Figure 7.5
SE5416A Series 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 7.6 shows the UDP settings.
77
Figure 7.6
Click on the COMX port under Serial on the left hand side.  Select UDP in the Link modes.  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 SE5416A Series can handle would highly depend on the traffic load. We have tested that SE5416A Series can handle up to 100 UDP nodes (baud rate 9600 bps, request interval 100ms, and data length 30bytes).
Enter the Local Listening Port. This is the port that SE5416A Series should listen to.
Match this setting in the UDP program (usually called destination port in the UDP program).
For serial settings, go to Sec. 5.4.1. For Advanced settings, go to Sec. 5.4.2.  Scroll to the bottom of the page and click on “Save Configuration” button to save the
changes.
78

7.2 Link Mode Applications

7.2.1 TCP Server Application: Enable Virtual COM

SE5416A Series 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 SE5416A Series’ 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 7.7 shows SE5416A Series in TCP Server mode with Virtual COM enabled.
Figure 7.7
Follow Sec 7.1.1 to configure SE5416A Series in TCP Server mode properly.  Click on the dropdown box of the Mode option and switch to “Virtual COM” to enabled
Virtual COM application in SE5416A Series.
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 Chapter 8. For
Linux, refer to a separate manual included in the Linux driver zip file. Remember SE5416A Series’ IP address and Local Port here in order to enter this information in
79
Serial/IP Virtual COM’s Control Panel later.

7.2.2 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 SE5416A Series in the TCP Server mode. To do so, refer to Sec 7.2.1 to enable Virtual COM, so that SE5416A Series 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.

7.2.3 TCP Client Application: Enable Virtual COM

It is also possible to run VCOM in TCP Client mode. It is usually easier to use Virtual COM in the Client mode if SE5416A Series uses dynamic IP (DHCP) because setting a static IP address in Virtual COM’s Control Panel in the Operating System is not possible.
Figure 7.8
Follow Sec. 7.1.2 to configure SE5416A Series in TCP Client mode properly.  Click on the dropdown box of the Mode option and switch to “Virtual COM” to enabled
80
Virtual COM application in SE5416A Series.
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 Chapter 8. For
Linux, refer to a separate manual included in the Linux driver zip file. Remember the
Destination Port here in order to enter this information in Serial/IP Virtual COM’s Control
Panel later.

7.2.4 TCP Client 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 SE5416A Series in the TCP Client mode. To do so, refer to Sec. 7.2.3 to enable Virtual COM, so that SE5416A Series 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.

7.2.5 TCP Server Application: Configure SE5416A Series 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 SE5416A Series to work in pair, one would be the Pair Connection Master and the other would be the Pair Connection Slave.
81
Figure 7.9
Follow Sec. 7.2.1 to configure SE5416A Series in TCP Server mode properly.  Click on the dropdown box of the Mode option and switch to “Virtual COM” to enabled
Virtual COM application in SE5416A Series.
Scroll to the bottom of the page and click on “Save Configuration” button to save the
changes.
Remember Pair Connection Master’s IP address here in order to enter this information in
the Slave later.
Proceed to the Sec. 7.2.6 to configure a Slave to connect to this Master.

7.2.6 TCP Client Application: Configure SE5416A Series as a Pair Connection Slave

A Pair Connection Slave, is shown in Figure 7.10; it is necessary to pair up with a Pair Connection Master. Please setup a Pair Connection Master first before proceeding.
82
Figure 7.10
Follow Sec. 7.1.2 to configure SE5416A Series in TCP Client mode properly.  Click on the dropdown box of the Mode option and switch to “Virtual COM” to enabled
Virtual COM application in SE5416A Series.
Match the Destination IP with the settings of Pair Connection Master’s IP that was setup
previously.
Scroll to the bottom of the page and click on “Save Configuration” button to save the
changes.

7.2.7 TCP Server Application: Enable Reverse Telnet

Reverse Telnet is useful if a telnet program is used to connect to SE5416A Series and the serial interface of the SE5416A Series is connected to a Terminal Server. Telnet programs in Windows/Linux require special handshaking to get the outputs and formatting show properly. SE5416A Series will interact with those special commands (CR/LF commands) if Reverse Telnet is enabled.
83
Figure 7.11
Follow Sec. 7.2.1 to configure SE5416A Series in TCP Server mode properly.  Click on the dropdown box of the Mode option and switch to “Reverse Telnet” to enabled
Reverse Telnet application in SE5416A Series.
Scroll to the bottom of the page and click on “Save Configuration” button to save the
changes.

7.2.8 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 7.12. 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, see Sec. 7.2.10.
Note: the destination IP and Port of the Slaves need to be equal to the Master’s IP and Port.
Local Listening Port for the Slaves need to be equal to the Master’s Destination Port, see table
below for an example.

7.2.9 TCP Server Application: Multiple TCP Connections

The Multi-Connection option will allow up to a maximum of four TCP Client connections. 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 (Sec. 7.2.10). For more information on Response behaviors please go to (Response Behavior).

7.2.10 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 control pins for RS-232. However, the TCP Server is limited to a maximum of four connections. If there are four serial devices and they don’t use flow control pins with RS-232 or RS-485, it is possible to setup pair connection in UDP mode, Sec. 7.2.8. After multi-connection is enabled in the WebUI, refer to the following table to setup Pair Connection as in Figure 7.14.
Figure 7.14

8 VCOM Installation & Troubleshooting

8.1 Enabling VCOM

SE5416A Series 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 SE5416A Series’ COM ports. Remember that VCOM can only be enabled on TCP Server Mode or TCP Client, Figure 8.1.
Figure 8.1
88
Figure 8.2
Virtual COM allows remote access of serial devices over TCP/IP networks through Serial/IP Virtual COM ports that work like local native COM ports; Figure 8.3 is a Virtual COM connection diagram.
89
Figure 8.3

8.1.1 VCOM driver setup

System Requirements
Windows 7/2008/Vista/2003/XP/2000/NT4/9x (32-bit or 64-bit version automatically
installs)
Native and virtual platforms, including Virtual Server and VMware  Linux, also available but first you might need to download a separate package called
Virtual COM driver for Linux (TTYredirector) available for download on Atop website or in the product CD. The zipped package includes a binary file for installation and a manual for Linux systems.

8.1.2 Limitations

The Virtual COM driver allows up to 256 Virtual COM ports in a single PC. Selecting in the range from COM1 to COM4096 is allowed. Note that COM ports already occupied by the system or other devices will not be available.
90

8.1.3 Installation

Run the Virtual COM setup file included in the CD or download a copy from our website to install the Virtual COM driver for the operating system. Turn off your anti-virus software and try again if installation fails. At the end of the installation, please select at least one Virtual COM port from the Serial/IP Control Panel.

8.1.4 Uninstalling

From Windows Start Menu select Control Panel, Add/Remove Programs.  Select Serial/IP Version x.x.x in the list of installed software.  Click the Remove button to remove the program.

8.2 Enabling Virtual COM

8.2.1 Enable VCOM in Serial device servers

Enable Virtual COM in our serial device servers by logging into our WebUI. It is located under COM configuration. Figure 8.4 show how to enable Virtual COM in SE5416A Series. For a detailed Link Mode configuration with Virtual COM, please refer to Sec. 7.2.1.
Figure 8.4

8.2.2 Running Serial/IP in Windows

Find Serial/IP Control Panel from:
Start → All Programs → Serial/IP → Control Panel In the Windows Control Panel, open the Serial/IP applet. In the Windows notification area, Figure 8.5; right click in the Serial/IP tray icon and
click on Configure to open the Control Panel.
Figure 8.5
If no Virtual COM port is selected, a dialog will pop up and asks to select at least one port as the Virtual COM port before proceeding, Figure 8.6.
92
Figure 8.6
After at least one Virtual COM port is selected, the Control Panel will show, Figure 8.7.
93
Figure 8.7
The left hand side of the Control Panel shows the list of selected Virtual COM ports. Click on Select Ports to add or remove Virtual COM ports from the list. The right hand side of the Control Panel shows the configurations of the selected Virtual COM port marked in blue. Each Virtual COM port can have its own settings.
Note: The changes to Virtual COM ports apply immediately, so there is no need to save the settings manually. However, if the Virtual COM port is already in use, it is necessary to close the Virtual COM port and open it after the TCP connection closes completely in order for the changes to take effect.
94

8.2.3 Configuring VCOM Ports

If the serial device server is running in TCP Server mode (recommended), a Serial/IP
should be the TCP Client connecting to the serial device server. Enable Connect to Server and enter the IP Address of the serial device server with the Port Number specified. The Port Number here is the Local Listening Port for the serial device server.
If the serial device server is running in TCP Client mode, Serial/IP should be the TCP
Server waiting for a serial device server to connect it. Enable Accept Connections and enter the Port Number. The Port Number here is the Destination Port of the serial device server. Do not enable Connect to Server and Accept Connections together.
Figure 8.8
Enable Restore Failed Connections to force Virtual COM to automatically restore failed
connections with the serial device server in the case of unstable network connections.
To test the Virtual COM connection, click the Configuration Wizard button and then click
Start button in the pop up window, Figure 8.9. If the test passes, all checks should be in green. To apply the changes in the Configuration Wizard window to the Control Panel,
