Description
The logger can transfer the data directly on a monitoring computer by radio frequencies (monitoring mode) or can store the data in its memory (recording mode).
Up to 500 loggers can communicate with one RF-USB stick connected to the computer. It is also possible to connect the PC to an Ethernet gateway. Recorders communicate with the gateway (collector) that sends data to a central data base.
