Serial server connects four devices

December 2009 Fieldbus & Industrial Networking

Advantech’s, EKI-1524 serial device server allows up to four RS232/422/485 serial devices to be remotely monitored, managed and controlled over Ethernet and Internet Protocol (IP) networks. Equipped with dual 10/100Base-TX Ethernet ports and dual media access controllers, this innovative device ensures data transmission even in the event of a network link failure.

With redundant Ethernet connections, communication is not interrupted in the event of a network problem. With one connection automatically assigned as primary and the other as backup, loss of the primary connection initiates an immediate and automatic switch-over to the backup, ensuring data integrity and peace of mind.

EKI-1524 offers a number of conventional operating modes that allow connections to be initiated by either attached serial devices or remote Ethernet hosts using both UDP/IP and TCP/IP protocols. For applications beyond simple point-to-point connections, two new multi-access modes allow one-to-many and many-to-one communications. The first allows up to five Ethernet hosts to access a single serial device and the second allows a single serial device to simultaneously send data to as many as 16 Ethernet connected hosts. In addition, serial transmission speeds have been increased to 921 Kbit/s, allowing a much broader range of serial devices to be network enabled.

EKI-1524 devices are ruggedised for demanding industrial applications with 4 kV Ethernet ESD protection, dual 12–48 V DC power inputs power line surge (EFT) protection and an operating temperature range of 0–60°C.
