System connectivity
The charger is equipped with three types of connection interfaces:
•
the WiFi interface: used for configuration purpose (when set to AP mode) and used for
network-based maintenance/management (when set to CLIENT mode)
•
the RS-485 interface: used to connect to an external meter in order to manage the
maximum available power for charging
•
the CAN Bus interface: used to interconnect a pool of chargers and perform the load
balancing between all of them
8.1
WiFi interface
There are two possible WiFi modes:
•
WiFi AP (Access Point)
•
WiFi CLIENT mode
The WiFi AP mode is the default one. The dedicated button on the front black display area,
under the black frontal cover, must be pushed for more than 3 sec. to switch between the two
WiFi modes (see the picture below where the switch mode button is highlighted by the red
circle).
8.1.1
WiFi AP mode
The WiFi
AP (Access Point) mode (also referred as “Hot Spot”) is mainly used for configuration
and monitoring purposes.
In this mode, the charger creates a WiFi network with a specified SSID and the user can connect
to that network, based on a point-to-point approach, to apply all the necessary configurations
or to monitor the charger parameters.
