      The EKI-1200 series Modbus gateways are bi-directional gateways for integrating new and existing Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based devices. The EKI-1221/1222/1224 feature two independent Ethernet ports and MAC addresses to provide a redundant networking mechanism to guarantee Ethernet networking reliability. They provide a simple and cost-effective way to bring the advantage of remote management and data accessibility to thousand of devices that can not connect to a network. The EKI-1221/1222/1224 provide a feature that can allow users to select master or slave operation mode for each serial port. They not only allow an Ethernet master to control serial slaves, but also allow serial masters to control Ethernet slaves.

  • USB Device Server

    Advantech’s USB serial device server allows PC users to connect serial devices via a LAN to systems that use USB interfaces such as USB monitors, printer, and scanners. USB-to-LAN serial device servers enhance user-intuitiveness and efficiency while cutting hardware requirements and other costs, and they enable the immediate conversion of connected devices, thus allow access from anywhere on your network. With hot swap and bus-powered support, our USB-to-LAN serial device servers avoid delays and problems from having to restart complex equipment, and there is no need for an external power supply. Our hot-swappable USB device servers come with bundled software, thus requiring no further card slots or IRQ addresses to be setup, a simple way to extend and share your USB device over long distances, for multiple users connected to your Ethernet network maintaining a virtual environment.

    • USB-4604B

      USB-4604 series allows PC users to connect a serial device to a system that use a USB interface. To attach the USB-4604B/4604BM to a PC, you don’t need to open the chassis or power down your PC. Instantly get extra high-speed RS-232/422/485 ports. The power is derived from the USB port, so there are no power adapters to deal with. This makes the USB-4604B/4604BM especially suitable for modems, printers, POS systems and industrial control devices. Supporting USB2.0 high speed, USB-4604B/4604BM features several powerful functions such as high-speed 921.6 kbps transmission, support for various operating systems, independent RS-232/422/485 ports and more. By simply plugging in a USB hub, USB-4604B and USB-4604BM eliminates the configuration issues associated with high-priced, older card solutions. You only have to install the drivers, no need to set cards slots, IRQ addresses, DMA channels, or device addresses. This reduces programming effort
