A serial to Ethernet technology is an electronic appliance that is capable of converting data packets received over the TCP/IP network into serial data signals and back. The hardware redirects a serial device across the network, thus eliminating the need for its physical connection to a computer. Since there is no need to install additional serial communication line, with RS-485 to Ethernet device you can rely on the existing structure of your LAN.

Best Serial to Ethernet solution

A great alternative to hardware would be Serial to Ethernet Connector. A dedicated software can provide your machine with remote access to any COM port peripheral over Ethernet, WAN, WLAN, VPN, or the Internet. The software lets you create an unlimited number of virtual COM ports in a system. No additional hardware, cables, or wires are required to connect to any remote serial device with this software tool.

Steps to connect Serial port to Ethernet network

Serial to Ethernet Connector eliminates the need for physical connections when accessing serial devices from your computer. This dedicated software application supports remote communication over the Ethernet using serial protocols including RS232, RS422, and RS485. Without the need of additional cabling, you can manage and control serial devices over the network with the same functionality enjoyed by a direct physical connection.

Here is an overview of the steps required to use RS232 to Ethernet software on your machine.

Download and install the application on the computer that will share a serial port as well as the machine that will access it remotely.
 Download Serial to Ethernet Connector
Start Serial to Ethernet Connector on the host computer which will share the serial interface. Select the ‘Server’ option in the program and customize the connection settings if desired. When customization is complete, click the ‘Create connection’ to make the port available for sharing.
 Start the app on the host computer
Launch Serial to Ethernet app on the computer that will access the serial port remotely and choose the ‘Client’ option to create the connection. Verify that you are using the same hostname and port number defined when you created the connection in the previous step and then click ‘Connect’.
 Create the connection

With these simple steps you have achieved a connection that provides complete access to the remote device which can be used as if it were directly attached to the client computer.

What is the use of the serial to Ethernet hardware?

The main purpose of this tool is to provide communication between serial devices and a computer via its COM ports that recognize the signals sent by a serial port over Ethernet. In practice, this means that using RS-232 to Ethernet hardware, you can access any serial device located within Ethernet (LAN) network from your machine, or manage a remote COM port peripheral over the Internet in case you use a Virtual Personal Network (VPN) or DNS.

The use of an RS-485 to Ethernet connector can simplify the work of both a regular customer and the whole enterprise. The device can be applied in dispatching systems, commercial or technological automated metering systems, serial to IP communications and many other areas.

How does a serial to Ethernet technology work?

  1. First of all, when you buy RS-232 Ethernet device, together with the hardware you get a driver software that needs to be installed on your PC. The program serves for creating virtual COM ports in the system when the hardware is connected to your machine.

  2. All virtual serial ports created with the help of the device’s software appear in your computer’s Device Manager as local ones.

  3. This way, any COM port embedded in a serial to Ethernet hardware can be displayed in a remote computer as though it was its own physical port.

  4. Now, any time you attach a serial device to a COM port of your RS-232 Ethernet connector, the peripheral is redirected to the virtual serial port of your computer and recognized by your PC as a local device.

Frequently asked questions about
Serial over Ethernet software

No. You can create an unlimited number of virtual serial ports and connections with both the trial version and the fully licensed versions of the software.
Yes. This COM to Ethernet software runs in the background as a Windows service which brings with it several advantages. The first is that all of your virtual serial to Ethernet connections are reconfigured automatically when you reboot the system and before users can log in. Additionally, the GUI can be closed once you have the connections configured and the service will keep them operational.
Server and client connections are treated the same way by this RS232 to Ethernet software application. Multiple entities can operate as clients with a single server or as servers to a lone client. Usually, the software is used with the servers sharing ports and the client for creating connections to remote machines.

The client-server architecture of Serial to Ethernet Connector usually involves installing the appropriate component on both sides of a connection. If the remote host is communicating via an application that can initialize outgoing TCP connections, there is no need to install the software on that machine.
The safety of the data you send with serial port to Ethernet connectivity is dependent on the way you configure the software. Serial to Ethernet Connector by Electronic Team, Inc. offers advanced data encryption that keeps your data safe from being intercepted by unauthorized users. When this option is active, all established connections are secure.
The data transfer rate is measured by bits per second (bps) in serial communication. There are standards rates that are usually employed for serial data transfer including:

110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 56000, 57600, 115200, 128000 and 256000 bps.

These speeds do not take into account the start, stop, and parity service bits but are only concerned with the effective rate of transmission. The advanced technology employed by manufacturers of motherboard chipsets has raised the possible data transfer speeds to over 1 Mbps. Data transfer speeds are impacted by the cable length used to establish connectivity and its relation to power supply lines.
