Advanced remote terminal features

  • Terminal server functionality: An RTU with reach-through serial ports gives convenient LAN remote access to control and configure switches, routers, and PBXs
  • Automatic control echoing: RTUs that can automatically issue control relay commands in response to alarm inputs. Switch on generators, open doors, cycle power, and many other applications
  • Nuisance alarm filtering: RTUs with timed alarm qualifications filter out momentary alarms and oscillating conditions, eliminating tiresome distractions
  • Alternate dial-up path reporting: Support for both LAN and dial-up connections gives RTUs an alternate reporting path in case of network failures, or you can gradually migrate your remote site monitoring from dial-up to LAN connection

View and acknowledge alarms on your remote terminal ... no master needed

  • Pager alarm notifications: Pager alarm notifications direct from your RTU let field techs respond to alarms in the field, speeding repairs and reducing windshield time. Pager-capable RTUs are perfect for after-hours monitoring
  • E-mail alarm notifications: E-mail alarm notifications direct from your remote telemetry unit create an automatic alarm history record, and keep supervisors informed of remote site problems
  • Web browser interface: Access your remote telemetry unit from any computer at any location. You don't need a master to view and acknowledge alarms, and everyone knows how to use a web browser without specialized training
