EtherLink/2 Ethernet Networking Device

EtherLink/2 datasheet (PDF; 180 KB)

High-performance Ethernet-to-serial router for ASI systems

Switch-selectable support for either RS-232 or RS-485

Built-in webserver provides simple, quick configuration interface

Provides both a TCP/IP and a UDP connection on one IP port

SNTP for time synchronization and timekeeping functionality

Flash memory upgradeable via built-in FTP server

Small footprint, measures approximately 5" x 1 1/2 " x 1"

Intelligent buffering and relay of alarms and events

The EtherLink/2 is a simple device to add Ethernet connectivity to an ASI controller or network, providing a cost effective solution for connecting ASI controllers to a new or existing TCP/IP network.

The EtherLink connects directly to the RS-232 modem port of a SINC/3-3000 Multiport System Interface. Using the optional null modem cable, an EtherLink/2 can be connected directly to the RS-232 Port of a single ASIC/2-7040 or ASIC/2-8040 controller.

The ASI Etherlink/2 offers advanced data buffering functionality. In situations where the remote server cannot be reached, whether it be due to network outages or other issues, the EtherLink/2 will buffer trend and alarm/event data and periodically attempt to deliver the data to it's destination. The intelligent data buffering capability helps control systems incorporating the EtherLink/2 to avoid 2 common problems: "holes" in the trend data, and missed alarms or event notifications.

The EtherLink/2 is configured with an IP address and setup parameters either directly through the built-in web server configuration interface, or by means of a dumb terminal program (e.g. HyperTerminal) connected to the RS-232 port.

The ASI WebLink graphical interface communicates via LinkOPC (OPC Server) to a remote ASI Controls device or network to provide full access to all devices on the remote network. The EtherLink/2 annunciates alarm and event notifications, with delivery to email or cellphone using WebLink remote monitoring and control software.

The EtherLink/2 is small and easy to configure, it can be installed and fully operational in minutes. A power supply is included.
