16 Introduction to the Wallbox eM4Single
Communication between a Controller and a backend via WLAN
x The Controller can communicate with an Internet-connected network via its WLAN interface.
x Communication via WLAN must be set up in the ABL Configuration App (see page35 onwards).
x Figure: The Wallbox eM4Single Controller1 is connected
wirelessly to a WLAN network2, which establishes commu-
nication with the selected backend4 via the Internet3.

Communication between a Controller and a backend via LAN
x The Controller can communicate with an Internet-connected network via its LAN interface.
x The connection is made via one Ethernet cable (Cat5 or better) per wallbox, which is routed into the wallbox via the supply cable
area.
x Communication via LAN must be set up in the ABL Configuration App (see page35 onwards).
x Figure: The Wallbox eM4Single Controller1 is connected
by cable to a LAN network2, which establishes communi-
cation with the selected backend4 via the Internet3.

Communication between a Controller and a backend via LTE
x Each Controller wallbox comes with an LTE USB stick that can be fitted with the SIM card of a backend operator and used in the
wallbox. This process is described starting on page32.
x In the reevready variants, the SIM card for communication with the reev backend is already pre-installed in the LTE USB stick in
the Controller.
x LTE communication with the backend must be set up in the ABL Configuration App (see page35 onwards).
x Figure: The Wallbox eM4Single Controller1 communicates
via the LTE USB stick with an LTE receiver2, which estab-
lishes the connection to the selected backend3.
