### eBZ DD3 (OBIS)
### eBZ DD3 (OBIS/SML)

The eBZ DD3 by eBZ GmbH is a three-phase model energy meter, which is sold in a number of different configurations. The D0 port is read-only with a fixed time interval of one second.

There are two communication interfaces:
* The INFO interface on the front, with a metal backplate. Pushes a reduces OBIS ASCI datagram every second.
* The MSB interface on the top, no metal backplate. Pushes a full OBIS ASCI datagram every second.
* The INFO interface on the front, with a metal backplate. Pushes a reduced OBIS ASCI/SML binary datagram every second.
* The MSB interface on the top, no metal backplate. Pushes a full OBIS ASCI/SML binary datagram every second.

There are two types available using different communication settings:
* OD-type: 7 data bits, even parity, one stop bit, 9600 baud (9600 7E1)
* SM-type: 8 data bits, no parity, one stop bit, 9600 baud (9600 8N1)
* OD-type: 7 data bits, even parity, one stop bit, 9600 baud (9600 7E1) - OBIS ASCI protocol
* SM-type: 8 data bits, no parity, one stop bit, 9600 baud (9600 8N1) - SML binary protcol

Tested with an eBZ DD3 2R06 ODZ1 (two-direction model for e. g. solar power metering).
