Advantech offers cost-effective and comprehensive industrial communication solutions.
Industrial Ethernet Switches & Media Converters
Advantech's EKI series Industrial Ethernet solutions offer a wide range of transmission media options, including: copper, glass fiber and "wireless." Data transmission rates can range from 10 Mbps, 100 Mbps to 1000 Mbps (or 1 Gbps), making the process of manufacturing data not just available at the field level, but also seamlessly integrated into higher-level data acquisition systems. Advantech’s EKI series X-Ring technology offers the fastest redundant ring recovery time (< 10ms) to secure data communication and reliability. Further, the robust design together with DIN-rail mounting and +12~48 VDC redundant power input make EKI suitable for rugged industrial applications.
Serial Device Servers
As the world becomes more and more network enabled, it becomes more critical to have the ability to remotely manage and connect devices. Advantech’s Serial Device Servers make it possible to quickly connect RS-232/422/485 serial devices with PC hosts over Ethernet networks or 802.11b wireless LAN networks. No extra programming effort is required on the host computer.
Serial Converters and Repeaters
Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422/485 standards overcome these limitations by using differential voltage lines for data and control signals. The Serial Media Converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as wireless and fiber optic signals.
RS-232/422/485 Communication Cards
The PCI Local Bus is a high-performance bus that provides a processor-independent data path between the CPU and high-speed peripherals. PCI is a robust interconnection mechanism designed specifically to accommodate multiple high performance peripherals for serial communication, SCSI, LAN, etc. The RS-232/422/485 serial communication cards leverage the "Plug and Play" capability defined in the PCI 2.1 bus specification, and are available with up to 8 ports depending upon the user's applications.
PC/104 & PCI/104+ Communication Modules
Advantech PC/104 Industrial Communication boards, featured with Ethernet, RS-232 or RS-422/485 ports, are designed for communication applications that requires good reliability and ease-of-use. These boards can be applied into embedded multiport applications, POS systems, ATMs, and small Internet Servers.
Overview
In an Industrial Ethernet environment, redundancy is always the primary consideration. To ensure the environment is reliable and always running, fast network recovery time is essential. Advantech’s EKI switches support standard and proprietary redundancy protocols, guaranteeing a stable and
reliable industrial environment.

Couple Ring/Dual Ring
|
|
X-Ring
|
|
In some industrial environments, it may not be convenient to connect all devices within a network. Advantech’s Couple Ring and Dual Ring are flexible topologies which can connect several distributed rings together and provide multiple paths.Communication between the rings can still operate even if one path fails.
|
|
EKI Managed switches support the X-Ring redundant architecture, allowing one switch in the ring to be the Primary Ring. One path of the Ring Master is the forwarding path, the other is the backup path. If one of the links fails, the Primary Ring automatically activates the backup path within 10ms. With the redundant ring mechanism, EKI managed switches provide highly solid and reliable communication for your system.

RSTP
|
|
Dual Homing
|
|
The Rapid Spanning Tree Protocol (RSTP) is an evolution of the STP and provides for faster spanning tree convergence after a topology change. The system also supports STP and the system will auto detect the connected device that is running STP or RSTP protocols.
|
|
EKI managed switches support Dual Homing for connecting with another network which runs RSTP or other ring protocols. Users can connect 2 paths to the same or different upper switches. This is a convenient way for the network planner to expand the network without replacing existed devices.
