2.9 Network and communication (x-series)
This chapter answers specific questions about networking and communica-
tion with the P30 x-series.
2.9.1 Network
Why do some charging stations have two Ethernet connections?
The Ethernet1 connector [X4] (LSA+) is intended for hardwired Ethernet
communication.
The Ethernet2 connector [X3] (RJ45) is for debugging purposes only.
Information
The Ethernet1 connection [X4] and Ethernet2 connection [X3] are con-
nected in parallel on the circuit board and cannot be used at the same time!
The connection that is not used must be unplugged.
Can the charging station be integrated into a network with DHCP server?
Yes, you have to deactivate the local DHCP server of the P30 x-series via
the configuration. The P30 is then assigned an IP address by an external
DHCP server.
How do I activate the local DHCP server?
With a P30 x-series, the internal DHCP server can be activated via a config-
uration file with the parameter "localDHCPserver = true" or in the web inter-
face.
After restarting the system, all slaves are re-assigned the same IP address
with the network ID 192.168.42.xx.
What are the options for an OCPP backend connection?
● External router (LAN/WLAN) with DHCP
● Mobile network (GSM 3G)
Which IP addresses may be assigned to the charging station?
The IP address range of an external DHCP server is not permitted to be
192.168.25.xxx as the charging station uses the internal IP address
192.168.25.1 and there would be an IP conflict.
