Emerson SiteLink-4 User Manual

Specification for SiteLink-4

DESCRIPTION: The SiteLink-4 is a 32 bit microprocessor-based communications device that provides an interface for up to four Liebert Unit Controllers (IGM’s). The SiteLink-4 communicates to either the SiteScan Monitoring System, or a third party software program utilizing a designated open standard protocol (i.e. Modbus or BACnet). This device communicates to the SiteScan Monitoring System via a twisted pair called the ARC156 network through an EIA-485 port at either 156K / 9600 or 38.4kbps baud. It communicates to the third party software monitoring system via a 9-pin DTE male EIA-232 connector (Portal Interface) or at the 5 pin EIA485 port communicating at either 9600bps or 38.4kbps baud. Four EIA-422 ports are provided to connect Liebert Information Gathering Modules.
