Introduction
The SiteGate-232 is part of the Liebert SiteScan gateway family and provides communications between
a workstation and a control module network (CMnet) consisting of fewer than 50 modules. The
SiteGate-232 provides two EIA-232 Console Ports for connecting a workstation and/or a modem. The
console ports are switch selectable for baud rates up to 38.4k bps.
Communication between the SiteGate-232 and the CMnet is provided through a EIA-485 port. The
SiteGate-232 does not have a Direct Network (DN) connection.
NOTE: You must use FB Link v2.7 or later in order to transfer to any module containing Exec 6.0 or
later.
