The Industrial Automation Group of Advantech introduces the EKI-1351 (1-port) and EKI-1352 (2-port) 802.11b/g Device Servers. These new models allow most any RS-232/422/485 serial device to be remotely monitored, managed, and controlled wirelessly, eliminating the need for hardwired cable connections.
Device Servers are a drop-in solution to add network connectivity to non-networked devices and equipment. With one connection for the network, and the other for attached RS-232/422/485 serial devices, Device Servers encapsulate serial data for transport over Internet Protocol (IP) networks. Used together in pairs as an extension cable for serial devices, or separately with a host computer or PC, Device Servers are an ideal solution to overcome the inherent distance limitations and point-to-point nature of serial devices.
Transparent Access to Serial Devices
For easy integration with COM-port based Windows applications, included COM-port redirection software allows virtual COM-port access to remote serial devices, just as if they were onboard COM-ports. With this tool, integration with PC-based systems takes just a few minutes, and it’s transparent to the host application software and connected equipment.
In addition to Virtual COM-port operation, the EKI-1351 and EKI-1352 support TCP/IP and UDP/IP aware applications like OPC Servers and HMI systems that support serial encapsulation. For simple applications, these units can be used in a peer-to-peer manner, where there‚â€™s no need for wireless infrastructure or access points. For more advanced applications, both client and server modes are supported, in support of serial device initiated or host initiated communications.
Advanced Operating Modes, and Multi-Access
Where one-to-many or many-to-one connections are required, Multi-Access mode allows a single RS-232/422/485 serial device to send or receive data to multiple remote hosts. This is particularly important in applications where multiple PC-based system need access to a single serial device for shared access, or where replacing systems that rely on a hardwired serial bus-type architecture.
Ruggedized for Industrial Applications
Like other EKI Industrial Ethernet family products, these 802.11b/g Wireless Device Servers are packaged in a compact and thin, DIN-rail mount chassis. Ruggedized for demanding industrial applications, these units offer 4,000 VDC Ethernet ESD protection, dual 12 to 48 VDC power inputs to maximize uptime, and power line surge (EFT) protection of 3,000 VDC.
