Optical communication head OKK-485
LMN communication adapter for base meters (eHZ) with RS485 interface
The new generation of the OKK-485 is an LMN (local metrological network) communication adapter developed by DIINNO for base meters (Basiszähler) of the eHZ type. Both design and performance have been significantly improved.
It provides the optical LMN interface (RS485) for meters without an integrated wired LMN connection.
