MEMORY

vanwalt DataHub: the heart of our Data Collection System vanwalt DataHub is a self-powered, flexible system of electronics, conveniently packaged in an IP rated, heavy duty aluminum enclosure which performs as a hub to collect data from environmental and other sensors. It organises the data for distribution or sharing through on-board memory, radio frequency, GPRS or satellite portals. Modbus, SDI-12, Analog and digital Inputs / Outputs are provided to connect sensors singly or in daisy-chain. vanwaltDataHub instructs, powers, interrogates and collects data from the sensors. Data is stored on non-volatile memory and backed up for redundancy and for convenience by an industrial grade SD card. Data can be downloaded by cable, by radio frequency transceiver, by GPRS, by satellite transmission or simply by the removal of the SD card. vanwalt DataHub is supplied as standard with on-board non-volatile logging memory, industrial SD Card memory, 2G or 3G/4G connectivity and batteries. Optionally it can be supplied with a Radio Frequency or Satellite Transceiver (Iridium) and solar panel. vanwalt DataHub can perform as a powerful and flexible standalone, power-independent datalogger but it can also interface seamlessly with our proven and highly flexible vanwaltCONNECT data acquisition and data Features • FTP Data Forwarding
