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

Power: 24 VAC ±10%, 50-60 Hz, 7.2 VA.

Console Ports: (2) EIA-232 serial ports (D-sub 9-pin connector, and 5-pin pluggable screw terminal block) switch selectable for 9600 or 38.4k bps.

CMnet Port: EIA-485, twisted pair, 9600/38.4k bps, optically isolated. (156k bps to be supported by a future version of the module driver).

Status Indication: Visual (LED) status of EIA-232 communication, CMnet communication, running, errors, and power.
