This 4-port panel mount Serial to Ethernet Converter with RS232, RS485 and RS422 interfaces is identical to part USC520 except that it has 4 serial ports instead of only 2 ports.
Each serial port can be used simultaneously or individually for either RS232, RS485 or RS422.
The serial ports are DB9 connectors which make it easy to connect standard RS232 cables; included are four DB9 / screw terminal headers which makes it easy to connect single wires for RS485 or RS422.
This converter is a strong industrial grade converter with several advanced features.
It is ideal for most applications and environments including commercial, industrial applications such as factory automation, warehouse installations and also consumer, office and laboratory applications.
This serial to Ethernet converter is designed around the ARM Cortex-M7 processor from Texas Instruments which makes this it a very reliable and high performance converter with several advanced functions. The Cortex-M7 processor incorporates multiple fail-safe and error detection features which ultimately results in less problems and more uptime.
As mentioned earlier this converter has several advanced features usually not seen in this range of converter, here are some of the features (please refer to the datasheet for all 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.
