Using a router
For a network connection using a router, the router automatically provides
the functionality of a DHCP server in most cases.
Information
If the IP addresses are assigned externally (for example, by routers with ac-
tivated DHCP server), the IP addresses must not be in the following range:
192.168.25.xxx
This address range is reserved for charging stations where the IP address
is set manually via DIP switches.
Using a switch
With a network connection via switch, the DHCP server of the KeContact
M20 (master) must be enabled via the web interface (configuration); it is dis-
abled in the delivery state. IP addresses are then assigned by the KeContact
M20.
2.2.2
Ports for communication in the charging network
For the correct communication in the charging network, the ports below must
be enabled network-internally.
Information
If necessary, contact your network administrator to enable the ports.
