Description

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 two 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.

ARM® Cortex™-M4 Processor

This serial to Ethernet converter is designed around the ARM Cortex-M4 processor from Texas Instruments which makes this it a very reliable and high performance converter with several advanced functions. The Cortex-M4 processor incorporates multiple fail-safe and error detection features which ultimately results in less problems and more uptime.

Advanced Features

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):

  • 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.

  • Both serial ports can be used individually at the same time.
    Both serial ports can be used wither as RS232, RS485 or RS422. The ports can be used as individual COM ports and transfer two separate data streams at the same time. After installing the included Virtual COM Software two separate COM ports will be created in your computer's Device Manager.

  • 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.

  • Web to Serial Mode.
    You can login to the converter with a web browser over a network and read the serial data processed by the converter.

  • Remote Reboot over TCP.
    If the converter for some reason should require a reboot because of a lock-up, for example due to a power outage or similar, it can be rebooted remotely over TCP by sending a HEX code to the converter. This is a very convenient feature if the converter is located far away.

  • Other Special Functions:
    Just to mention a few of the minor features:
    • Non-standard custom baud rates from 600 to 230.400bps
    • Two TCP sockets can receive data from serial port simultaneously
    • Hardware flow control RTS/CTS
    • Software flow control XON/XOFF
    • User defined MAC address
    • UART and Ethernet Heartbeat packet function
    • Two Ethernet sockets available

    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.
