ACU-Network – GPRS configuration
The ACU has a built-in modem and can communicate with
the backend of the charging network operator via GPRS.
Fig. 15: ACU-Network – GPRS configuration
To avoid unnecessary costs, the SIM card should have a
flat rate for data volume.
Depending on the backend used, further requirements
on the SIM card may exist that are not covered in this
documentation.
Requirements:
 The ACU uses a valid SIM card.
 The ACU is not connected to a backend via the LAN
interface.
 You have valid login details (access point name, user
name and password) of your mobile service provider.
