MiniCSU-3
Remote Communication Interface
• Embedded modem option (standard or PPP versions)
– capable of dialling out to 3 phone numbers until
connection is made to report alarms or daily reports
• Isolated RS-232 or RS-485 options for connection to
central monitoring room
• TCP/IP option for ethernet connection
• WebCSU option for Ethernet, SNMP or HTTP connection
Note: All remote communications options operate with the WinCSU
monitoring and control PC software. The WebCSU unit provides the
additional Web-browser and Network Management System (NMS)
capabilities.
