The iEM3000 series meters provide a large amount of information on basic MBus, including streams and power in each phase. Enter settings To enter the settings, press and hold the OK and ESC buttons for a few seconds. The factory password is 0010. Scroll to each digit with the arrow key and confirm with OK. Setting the gear ratio of the measuring transformers Use the arrow button to scroll to CT&VT Ratio, press OK to set.

Cold and hot water meters from the Italian manufacturer Gioanola use their own system of pulse outputs. The read head with a reed contact always senses a dial that is markedly marked and different from the others. Therefore, if, as in the following figure, a target measuring one thousandth of m3 (0.001 m3) is measured, the weight of one pulse is one hundredth of m3 (0.01 m3).

Concentrator installation The physical installation of the MBv master Elvaco CMe2100 is very simple connect the MBus to the terminals marked MBus master insert a SIM card connect the antenna to the SMA connector and place it in the place with the best signal - ideally outside of the rack connect 230V power supply to L a N terminals - standardly connected via 2A - (B), 10kA circuit breaker if the red LED is lit, either you have a short circuit on the bus or too many meters connected List of SMS …

Connecting the module to the computer with a cable The USB-CMOS cable supplied by the manufacturer is connected to a free USB port on the computer. Then in the Device Manager window we find the assigned COM port number, eg COM7. Module configuration using PUTTY We make configuration using any serial line communication program, we recommend PUTTY program, which is free to download on the Internet. Launch PUTTY On the Session tab set:

The converter can connect up to 250 M-Bus meters to a RS-485 physical concentrator. Communication still runs on the M-Bus protocol, so it can only be used on devices that enable this combination, such as SmartCom 485. The converter itself does not need to be set. Converter Connection 1, 2 - M-Bus with meters 3, 4, 5 - RS-485 (+, -, GND) 6, 7, 8 - power supply 230V ~ (PE, N, L)

Concentrator wiring The wiring of the MBus master Elvaco CMe3100 is as follows: Connect the power supply to terminals L and N - standard via a 10A circuit breaker - type C characteristics. Connect the MBus to the terminals marked M-Bus master. Finally, connect a network cable with RJ45 Cat5e or later generation terminals to the port marked Ethernet - if properly connected to the network, the yellow LED marked LAN will light up and the red LED marked ERR will light up when the IP address of the …
