19.1 Communication interfaces
Different interfaces like optical or electrical interfaces (RS485) are available for reading or
configuring the meter. Using one of these interfaces the meter can be readout by a handheld
unit or PC in combination with an optical probe or by connection the meter to a modem for AMR
purposes.
The data protocol is implemented according the DLMS/COSEM protocol. The data model is
compliant to IDIS package 2 and 3
19.1.1 Optical interface
The characteristics of the optical interface are listed below:
• Electrical characteristics: as per EN 62056-21
• Protocol: as per DLMS/COSEM
• Baud rate: max. 9.600 / 19.200 baud
19.1.2 Wired M-Bus interface
The characteristics of the wired M-Bus interface are listed below:
• Electrical characteristics: as per EN13757-3
• Protocol: as per EN13757-2 physical and link layer
• Baud rate: 2.400 baud
