AirGate connection to the PC
This connection type is used for connection to controller (s), that are connected to the Internet, however they
do not have public and static IP address. The controllers connect by InternetBridge-NT module to the
AirGate server and cyclically ask whether there is a connection request from a client or not. On the other
side the clients (only ComAp PC applications - DriveConfig, DriveMonitor InteliMonitor and WebSupervisor)
connect to the AirGate server instead of connecting directly to the controller. The server then creates a
"tunnel" between the client and the controller.
Hint:
InternetBridge-NT (IB-NT) connection into Internet network can be done via Ethernet or Cellular connection.
The Ethernet connection can be realized by direct access using fixed and public IP address as well as by
private network access using dynamic non-public IP address (behind Firewall, NAT, DHCP server etc. –
situation illustrated in the picture above).
Hint:
AirGate ID needed as parameter for connection creation is assigned to InternetBridge-NT (IB-NT) module.
Second parameter for connection to a particular controller is controller’s address (there can be connected up
to 8 ID-DCU Marine controllers via CAN2 bus to one IB-NT module).
