This serial to Ethernet converter is our most advanced and solid converter available of the two-port type. Not only does it have RS232 ports but it also has individual RS485 and RS422 ports. The RS232 ports are standard DB9 connector ports and the RS485 / RS422 ports has screw terminal headers for easy connection of single wires.
It supports communication protocols for most applications such as CNC machines, weighing scales, laboratory equipment, printers, factory automation and most other industrial applications.
The processor in this serial to Etherneet converter is a Wport-W20 procesor from Ralink which provides reliable and solid performance with most applications. The embedded, high performance CPU can easily manage advanced applications such as Ethernet data processing without overloading the host processor. The eCos operating system provides a strong platform supporting TCP/IP, Telnet and Modbus TCP Protocols.
Besides supporting all standard basic functions such as baud rates between 300 and 230400bps, RS232, RS485 and RS422 interfaces, DHCP support and AES security, it also supports more advanced functions. Here are some of the advanced functions (please refer to the datasheet for all details):
- Two Ethernet ports - LAN/WLAN
This converter can be accessed and communicate either over LAN or WLAN. Two differnt communication protocols in the same converter.
- Modbus compatible.
Industrial applications often use the Modbus protocol to communicate with serial devices. This converter is fully compatible with the ModBus TCP and RTU protocols.
Using standard Telnetd the converter can be accessed and communicate over a Telnet connection. Many network administrators prefer this
method instead of web-access.
- Multiple TCP Sockets support
This converter can support up to 5 TCP sockets. Each socket can communicate individually over TCP/UDP in Server or Client mode. Multi Socket simultaneous communication of data stream is as following.
- Multiple Clients Support.
Each serial port supports up to 8 simultaneous clients in TCP mode, meaning that 8 computers can connect to the converter at the same time. This is a nice feature to have if you have a large network with many clients.
- Configuration over serial (CLI)
The converter's parameters can be configured through the serial RS232 port using CLI commands. Useful if configuration through Wi-Fi or Ethernet is not an option.
- Other Special Functions:
Just to mention a few of the minor features:
- Wide power range 5 - 36VDC
- Adjustable number of simultaneous clients acceptable (max 32)
- HTTP support
- Route Configuration. The data received from Socket channel can be set to another socket channel
- NTP function
- Adjustable TCP socket Keep Alive
- Adjustable TCP socket Timeout
- Hardware flow control RTS/CTS
- Software flow control XON/XOFF
- Adjustable buffer size and gap time
- MAC address
- Adjustable timeout counter
Please see the 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.
