Spinwave Systems, Inc.

BMS Protocol Interface, SWRF-MODBUS-TCP & SWRF-MODBUS-RTU

Type:  Network Gateway
Description:  Spinwave Systems' BMS interface easily connects Spinwave's wireless sensors to open-protocol building automation systems. The wireless BMS interface consists of an RF receiver module and an open protocol (TCP) interface. Up to 31 separate wireless devices (sensors and/or repeaters) are supported per BMS interface. Sensor data points are mapped to BMS network variables and are presented to the Building Management System as Modbus registers.
Connectivity:  Modbus, Modbus TCP
Features:  Flexible mounting options to accommodate a broad range of installation requirements; multiple interface options-easily integrates with virtually any building automation option; RF receiver module and Modbus TCP interface (SWRF-MODBUS-TCP) or Modbus RTU interface (SWRF-MODBUS-RTU)
Specifications:  Radio Characteristics: 2.4GHz, IEEE 802.15.4, Receiver Sensitivity -95dBm, Receiver Adjacent Channel Rejection +/-5MHz, 46/39 dB, Receiver Alternate Channel Rejection +/-10MHz, 58/55 dB; Open field Range: Receiver/Router: up to 3500 ft. (1 km), Receiver/Sensor: up to 700 ft. (230 m) In-building Range per hop (Sensor to Repeater or Repeater to Repeater) 120 ft. (40 m) in typical commercial office building; Power: 24VAC (+/-20%), 30 VA
