The Advantech EKI-1524I-BE is a Serial Device Server with four serial interfaces, designed for data transmission between serial devices and an Ethernet network. The device enables the integration of legacy systems communicating via RS-232, RS-422, or RS-485 into modern IP-based networks. It is specifically designed for applications requiring high availability and reliability, such as industrial environments or remote device maintenance. The model designation 'I' indicates a wide operating temperature, making the device suitable for use in harsh environments.

Applications

The EKI-1524I-BE is typically used in industrial applications where serial devices such as sensors, measuring instruments, machine controls, or printers need to be accessed over a network. It is particularly suitable for installations operated outdoors, in production halls, or in environments with significant temperature fluctuations. Support for LAN redundancy via two Ethernet ports increases system availability, as a second path is available in case of a network failure. The COM port redirection function (Virtual COM) allows serial devices to be accessed over the network as if they were local COM ports, simplifying integration into existing software solutions.

Functions and Features in Detail

The device offers four serial interfaces, which can be configured as RS-232, RS-422, or RS-485 as needed. The maximum transmission rate is 921.6 kbps, with any baud rate configurable to ensure compatibility with various devices. Support for TCP and UDP modes enables flexible network connections. Up to five hosts can simultaneously access a single serial port, while in TCP client mode, up to 16 hosts can be addressed. This configuration is useful in scenarios where multiple clients need to access the same serial resource, for example, in remote monitoring or control.

Technology Explained Simply

The EKI-1524I-BE features integrated protection functions that enhance reliability. A 15 kV ESD protection function safeguards all serial signals against electrostatic discharges that may occur during handling or operation. Additionally, the device offers 4 kV overvoltage protection between lines and 8 kV overvoltage protection between line and ground, making it robust against transient voltage spikes. Automatic data flow control for RS-485 enables efficient communication without additional hardware. Configuration is possible via various methods: a Windows utility, a Telnet console interface, or a web browser, facilitating adaptation to different working environments.

Compatibility and Accessories

The device is compatible with a wide range of operating systems, including 32- and 64-bit versions of Windows 2000 to Windows 8.1, Windows Server 2003 to 2012, Windows CE 5.0, and Linux. This broad support enables integration into heterogeneous IT environments. The 'I' series is designed for a wide operating temperature, making it suitable for industrial applications where ambient temperature can vary significantly. The 'CI' models offer additional isolation, but this is not included in the EKI-1524I-BE variant.

Mounting and Installation

Installation is performed using the provided configuration methods. The devices can be integrated into rack systems or operated as standalone units. Network connection is made via the two 10/100 Mbps Ethernet ports, designed for LAN redundancy. The serial connections are implemented via DB9 connectors, standard for RS-232/422/485. Configuration is done via the mentioned interfaces, with the web browser option providing a graphical user interface that clearly displays the settings.

Operational Advantages

The EKI-1524I-BE provides a reliable and flexible solution for integrating serial devices into IP networks. Support for LAN redundancy increases system availability, while integrated protection functions ensure robustness against electrical disturbances. The ability to allow multiple hosts to access a single port, along with support for various operating systems, increases usage flexibility. The wide operating temperature makes the device suitable for use in harsh environments without requiring additional cooling or heating systems.
