Industrial DIN rail converters used to cost a lot in the old days, fortunately things has changed. Cutting edge technology and streamlined production lines has made industrial grade converters cheaper without sacrificing quality. With this in mind we here present our new DIN rail mountable Serial RS232 to Ethernet converter. Perfect for building into electrical control cabinets, racks and enclosures of any kind which has a DIN rail.
ARM® Cortex™-M Processor
This RS232 serial to Ethernet converter is designed around a
32-bit microcontroller (STM32F0) from STMicroelectronics containing a ARM® Cortex®-M processor, which makes this converter a modern high performance, reliable solution with all basic functions and several expanded/advanced functions. Ideal for most industrial and commercial applications and environments.
Basic Features
All basic functions of a standard serial RS232 to Ethernet converter are supported, which includes the following:
- DHCP and Static IP address.
By default the converter is set to have a static IP address, this can be changed to DHCP so your network or computer automatically assigns an IP to the converter.
- Serial port settings.
All standard port settings such as baud rate, parity, data bits and stop bits can be set within the standard range.
- Parameter configuration via web-browser.
All parameters can easily be changed by logging into the converter using a standard web-browser such as Chrome, Firefox or Internet Explorer. This can be done on a local network, or from a remote location using a 3rd party DNS service.
- Network modes.
The converter can be set to the most commonly used network modes which includes: TCP Client, UDP Client, TCP Server, UDP Server or HTTPD Client mode.
- Virtual COM port software.
To create a virtual COM port with any serial to Ethernet converter you will need a virtual COM port software. With this converter it is a full function free downloadable software. No extra cost.
Expanded functions
Since this serial to Ethernet converter has been designed with the ARM® Cortex® STM32 microcontroller mentioned earlier it has been possible to incorporate a few expanded/advanced functions, usually not seen in this range of converter, here are some of the functions (please refer to the datasheet for all details):
- Number of connected clients.
This function lets you manually select how many clients (max 8) you will allow to connect to the converter simultaneously. Very useful for control and security of the connected devices.
- Heartbeat packet function.
A heartbeat packet can be sent to either the TCP port or the serial port to keep the connection open.
- Registration packet function.
A registration packet can be sent to
the server to identify the data source device or to obtain a password for the server authorization. The package can be sent to establish the connection, when carrying data or both. It can be created by MAC register or self defined register.
- Impersistent connection.
If there is no data reception in the serial port or network port within the set time, the connection will be automatically disconnected. Mainly used to save server resources.
- Reset, Link and Index.
These are additional functions which manually can be enabled or disabled in the converters administration panel:
Reset: if enabled the converter will automatically reset itself if the TCP connection has not been successfully built after a number of tries.
Link: TCP connection status, connected or not connected. A pin on the PCB goes low if the connection is successful and high when unsuccessful. This function is only available on the PCB.
Index: This function can be used to identify the server and client of the sent data if there are multiple servers and clients on the network.
- Other (lesser used) expanded functions:
- TCP kick-off old connection
- Buffer data before connected
- UART set parameter
- Reset timeout
- Synchronous baud rate RFC2217
Please see datasheet and user manual for more details.
Besides the features mentioned above this converter is also fully capable of handling more complex setups such as Serial Tunneling mode, communication without virtual COM software, access over Internet and more.
