Note: For meter of the type T550 firmware ≥ 5.17.
For meter of the type T550 firmware ≥ 5.23 new functions are
availed (C1 mode, OMS 4.1.2 with security profile B).
The radio module 868 MHz enables the meter to communicate with a center
(receiver) using 868 MHz radio frequency. The module supports OMS
compliant data transmission with radio mode T1 or C1 and with or without en-
cryption (see chapter 16, 17).
A data transmission to an OMS radio concentrator (Smart Meter Gateway) or
the L+G mobile radio readout system Q4 is possible.
