If the VNS104 was not congured during installation, or changes to the controller,
the PC, or the network have occured and the VNS104 is unable to contact the
controller, the controller is not properly licensed, or the VNS104 shares the same ID or
checksum with an existing VNS104, then the application displays “Unable to contact
controller” on the splash screen (see gure 16, below).

same network as the VNS104.
