Advantech Launches Advanced Wireless Serial Device Servers

Advantech has introduced two new wireless serial device servers, the EKI-1351 and EKI-1352. These WLAN enabled devices combine 1 or 2 RS-232/422/485 ports with support for the new 802.11b, and 802.11g protocols. Furthermore, each COM port features high-speed throughput (up to 1.2Mbps) with 921K-baud technology. EKI-1351 and 1352 also have built-in dual-power inputs (12~48VDC) with 1 power fail relay to detect operation status and ensure the device works normally. Advantech claims that these features make the EKI-1351and EKI-1352 the most flexible and powerful wireless serial device servers currently available to the industrial market.

For example, TCP server/client and UDP mode allow simultaneous connection with up to 5 hosts through the RS-232/422/485 serial ports for advanced data transmission and communication, such as broadcast and polling operations. In broadcast mode, EKI Serial Device Servers handle a command from one application and reply to the data from the serial port to all applications connected to this serialport. In polling mode; EKI Serial Device Servers handle the commands from one application and reply to this application only. Query from other applications must be queued and wait for current process completion.
