After the invention of the USB protocol,
we can hardly see any serial devices these days. For this reason of modern
transfer systems, most manufacturers no longer add a serial port on a laptop,
desktop computers, or modern devices.
Therefore, devices like serial printer,
scale, barcode scanners, serial consumer/ industrial devices, GPS, surveillance
cameras all have one thing in general and that is they all use serial cable
connections such as RS232, RS422, or RS485 to interact with a computer.
Establishing remote access to this set of
a device from a remote computer is the trouble that I thought to describe to
you how you can get rid of it. Don't worry, a serial-to-Ethernet converter
enables you to connect most serial devices to an Ethernet port which you can
directly use on your computer or switch or a network router and control that
device.
Definition of Serial to Ethernet converter
A serial to Ethernet converter is a small
size device that is sometimes known as a serial device server, a serial over
TCP/IP server, or simply a terminal server. However, all these names are just
different names for the same kind of device that fundamentally converts serial
(RS232, RS422, or RS485) data to Ethernet packets and Ethernet packets to
serial (RS232, RS422, or RS485) data bi-directionally.
It can be utilized as a wireless
converter also if the IP/TCP data packets are transmitted over the IEEE
802.11a/b/g network link. The converter redirects a serial device over the
network. Hence it eliminates the necessity for its physical connection to a
computer. The serial to Ethernet converter has its unique IP address. That is
the reason, it is often referred to as a server.
Working process of serial to Ethernet converters
First of all, when you purchase a serial to
ethernet converters, together with the hardware you perceive a
driver software that requires to be installed on your computer. The program
works for creating virtual COM ports on the computer as soon as the hardware is
connected.
All the virtual serial ports are created
with the assistant of the device's software arrive in your computer's Device
Manager as local items.
This approach, any COM port implanted in
a serial to Ethernet hardware can be displayed in a remote computer as if it
was its own physical port.
Now, every time you connect a serial
device to a COM port of your serial to Ethernet converter, the peripheral is
redirected to the virtual serial port of your computer. Now it gets recognized
by your computer as a local device.
Setting up a Serial to Ethernet converter
Install
the driver
Most serial to ethernet converter systems
come with virtual COM port drivers added. You have to install it on your
computer before you can begin using the converter. Once the installation
process is finished, the virtual COM software will immediately be capable to
create a virtual COM port in your computer's Device Manager at the time the
hardware is connected to the computer.
Set
up the hardware
To set up a serial to Ethernet converter,
simply connect the Ethernet cable, the serial cable, and the power supply
adapter.
Configuring
the settings
After finishing all the steps said
earlier, you can begin configuring the converter. Almost all the converters
however serve directly out of the box because it will automatically detect the
serial interface you are using with all other settings.
If you, however, need to configure the
default settings then you can log in to the converters administration panel. You
can sometimes log in to the units admin panel by accessing the virtual COM
software, nevertheless mostly it is quicker and simpler to use a web browser.
Just enter the default IP address of that
converter in your browser address bar and you will see to your serial to
ethernet converter's admin login page. Now you will be able to configure your
converter based on your preferences. You can find more information on https://www.pusr.com.
