The connection key is the key that enables communication between the display unit and either the GP-Pro EX Transfer Tool or GP-Viewer EX.
The connection key is set on each display unit.
When a connection key is set up, authentication of the key is required before sending or receiving project data or viewing the display unit screen on your computer.
