NOTE:
The IP addresses of the controllers must be accessible from the remote computer. If the remote
computer is connected into another LAN segment than the gen-sets are, there must be a gateway(s)
that enable direct traffic between the segments. If the remote computer is connected via Internet, then
the internet gateway of the LAN where gen-sets are connected must have public IP address, must
allow incoming traffic and must provide port forwarding from the external public IP to the different
internal gen-set IPs according to the port used.
INTERNET GATEWAY CONFIGURATION EXAMPLE (PORT FORWARDING)
Equipment
Ethernet cable to LAN, for point to point connection
between PC and controller use cross-wired cable
Direct PC connection to Multiple gen-sets
