Product Overview

BASview2 is a stand-alone, embedded, web-based graphical interface for building automation and process automation systems. It can be accessed from any web browser — providing client functionality to any BACnet/IP or Modbus TCP system. By using Contemporary Controls BASrouter or BASgateway products, additional protocols such as BACnet MS/TP and Modbus RTU are supported.

The BASview2 is simple to install and use. A 10/100 Mbps Ethernet connection is all that is needed. Client features include animated graphic screens, scheduling, historical trending, runtime accumulation and alarm monitoring. BASview2 will automatically toggle outputs and change setpoints on schedule, collect runtime and trend data, and monitor alarm conditions. As an embedded device, BASview2 uses Flash memory for internal storage instead of a hard disk to maintain its ruggedness. The BASview2 is totally self-contained, requiring no external PC or application for its use. Any number of web browser users can access the device.

The BASview2 is ideal for small to medium buildings or processes that require a simple-to-use graphical interface with no licensing requirements.


  • HTML5 – no Flash required
  • Animated graphics
  • Internally maintained schedules with sunrise/sunset and stagger offsets
  • Trend collection, display and export
  • Runtime accumulation with email notification
  • Alarm condition monitoring with email notification
  • Calculated point values (average, min, max, etc)
  • Python programming language for controlling equipment
  • Database of up to 32 users and 32 user groups
  • Multiple simultaneous users
  • Activity log for tracking important user actions
  • Template system for quickly cloning points, graphics, devices or entire networks
  • Calculations may be performed on data points
  • Support for up to 2,000 tree nodes which can be any combination of points, graphics, trends, etc.
  • No software licensing requirements

The BASview2 is housed in a compact metal enclosure that is DIN-rail mounted. It requires a 5 VDC voltage source and is shipped with a universal mains input power supply. Internally powered by a 1.2GHz quad core ARM CPU, it has 1GB RAM and 8GB of Flash memory for data storage. The device has a battery-backed real-time clock. Simply connect the device to a BACnet/IP or Modbus TCP Ethernet network to access both BACnet and Modbus compliant equipment. For non-Ethernet based equipment, BACnet MS/TP to BACnet/IP routers or Modbus serial to Modbus TCP routers can be used. By using Modbus serial to BACnet/IP gateways, the complete system can be treated as a BACnet system.
