1.1Introduction
Advantech's EKI series of Industrial Device Servers are a robust, feature-rich, and cost effective way to network-enable equipment in an industrial automation environ- ment. The EKI-1351/1352 provides one or two serial ports, 802.11b/g wireless LAN interface to connect any RS-232/422/485 devices to wireless LAN. These wireless serial device servers provide serial-to-wireless network connectivity as an alternative to wired Ethernet connectivity and enable virtually any serial device or equipment to be remotely accessed, controlled, monitored, or shared on an 802.11b/g wireless network.
By encapsulating serial data and transporting it over Ethernet, the EKI-1351/1352 allows virtual serial links over Ethernet and IP (TCP/IP, UDP/IP networks. After Advantech Serial Device Server Configuration Utility installation, standard serial operation calls are transparently redirected to the serial device servers, guaranteeing compatibility with legacy serial devices and enabling backward compatibility with existing software. EKI-1351/1352 also supports serial tunneling, allowing two native serial devices to communicate over a network without any hosts and programming.
As a result, you can extend limited distance, point-to-point, direct serial connections within the plant, throughout the factory, the facility, the office building, or across the global enterprise.
The EKI-135/1352 provides an impressive list of features and functions enabling mul- tiple industrial devices to be connected, controlled, configured, managed, and updated over a network. With serial ports and 802.11b/g wireless LAN, the EKI-1351/ 1352 can easily connects multiple serial devices to a network.
The transmission speed of the EKI-1351/1352 is up to 1.2M bps totally outstripping the competition to meet the demand for high-speed exchange. Functionally transpar- ent and efficient, the EKI-1351/1352 is especially designed for remotely controlling and monitoring devices via the Internet.
Type of supported devices:
Human Machine Interface (HMI)
Programmable Controller (PLC)
Flow meters
Temperature / pressure monitoring equipment
Gas leak detection device
Scales
Power monitoring equipment
Data Acquisition Modules
EKI-1351/1352 provides various TCP/UDP operations: COM port redirection (Virtual COM port), TCP server/ client and UDP mode. Serial devices can be connected
by means of multi-access modes.
