Introduction to Tinytag Connect

Tinytag Connect is a central data management feature for Radio and LAN loggers giving users on a network remote access to data being recorded. Data is presented in the Tinytag Explorer Connect software: a viewing pane presents a global view of the monitoring application: information from multiple points can be easily accessed by any permitted user on a LAN, or over the internet by setting up VPN access to the computer running the system.

Connect functionality enables multiple loggers to be configured and downloaded simultaneously, and they record locally in the event of communications problems ensuring no data is lost. Alarm warnings, either audible or sent via email enable corrective action to be initiated.
