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).
• Check the Enterprise controller IP address and port number settings in the network
configuration of the VNS104 (see VNS104 Configuration on page8).
• If the values are correct, ensure that the controller is powered and connected to the
same network as the VNS104.
