Model 831-INT Docking Station Model 831-INT Docking Station Compact Interface for All Accessories in a Noise Monitoring Station Highlights I I I I I I I 831-INT-ET adds Ethernet network connection for broadband communication Weather sensor interface Powered USB hub for communication, weather and GPS AC, battery or solar powered Battery charge management including solar power Power for Model 831, outdoor microphone weather sensor, and communication Fully supported by 831 SDK for system integrators Cabling made easy Live audio streaming Permanent Noise Monitoring Temporary Noise Monitoring Model 831-INT seamlessly integrates the Model 831 with it’s wide range of accessories The Model 831-INT provides the 426A12 outdoor microphone with both electrical power and control commands for its electrostatic actuator, temperature and humidity readout. The Vaisala WXT520 (SEN031) weather sensor is connected to the Model 831-INT for wind speed and direction, temperature and humidity, barometic pressure, rain and hail. The Model 831-INT further simplifies cabling by providing a USB hub where the GPS, analog modem or wireless gateway connect. The AC power unit also controls the intelligent charging of the Sealed Lead Acid (SLA) backup batteries. The DC power input is available for solar powered installation. The enhanced 831-INT-ET version extends the reach of the Noise Monitoring Station (NMS) with TCP/IP based broadband connection, even allowing live audio streaming. It is fully supported by the 831 SDK making it an ideal solution for system integrators. Finally, the Model 831-INT hosts the Model 831 sound level meter as the heart of a permanent NMS.
