DB9 to Ethernet Connector Software - Serial to Ethernet

How does one access DB9 over network?

You can provide shared access to your local device for your network computers. First of all, download Serial to Ethernet Connector and install the software to all computers in your network (LAN/WAN or Internet), which will use the required DB9 port. After that access your DB9 port on remote computer, as if it was on your local PC.

With the help of installed DB9 to Ethernet Connector you will be able to:

Share serial port for incoming connections (Server)

Server connection shares local ports – virtual or real – over Ethernet. Incoming client connections can transfer data to their local port while Serial to Ethernet Connector joins these data streams on server.

Connect serial port to remote host (Client)

Client connection allows redirecting data from a local port to the remote server over TCP/IP protocol. Once you specify the remote server’s IP address and TCP port to connect to, the connection is established and data sent from the remote end gets delivered to a local port.

Broadcast over UDP

Data from serial ports can be transported over UDP/IP protocols. Thus all your serial data can be broadcast over your local network.

The software supports Windows and Linux operating systems; the current Linux version is a command-line product.

What is DB9?

DB9 serial port is typically used for connecting peripheral devices to a computer (keyboards, mice, printers, etc.). DB9 connectors are also utilized in DB9 cable assemblies for data connectivity.

Nowadays USB, PS/2, Firewire and other modern interfaces are replacing the RS232 DB9 standard, and modern computers are rarely equipped with RS232 DE 9 ports. However, some devices still require such port to connect to a PC.

What do you do if you have to access such a device if there is no DB9 port in your system? Some apps still require an existing serial port to start work and receive data. Find a computer that has one, insert the device into it and access it over network with the help of DB9 software.

DB9 Pinout - RS232 Pinout

Below you can find the pinout of a standard male 9-pin RS232 connector (known alternatively as a DB9 connector).

A serial port that resides on your PC is usually a male port (DTE), see below. A female interface (DCE) is usually found on serial devices that can be connected to the computer’s port.

The pin numbers with signal names and the signal direction are shown in table below.
