Liebert 232 user manual Introduction, Specifications

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.

Specifications
