Page 6: Description Of The M-Bus Level Converter
GmbH, Stettiner Str. 38, D-33106 Paderborn 2 Description of the M-Bus Level Converter Functionality: The RS232C and RS485 interface signals are directly connected to the M-Bus all the time besides during the operation via keyboard, the remote access using the command menu and the automatic readout. - Page 7 GmbH, Stettiner Str. 38, D-33106 Paderborn Planning M-Bus networks: Two effects must be taken into consideration before projecting M-Bus networks: 1. The signals must not be distorted to much by the influence of the capacitance of the cable. The capacitance of the network depends on the length of the network, this means the total sum of cable length.

Page 8: Description Of The M-Bus Display
GmbH, Stettiner Str. 38, D-33106 Paderborn 3 Description of the M-Bus Display Functionality The M-Bus Display allows reading the meters using the keyboard and viewing the consumption values on the LCD. The reading personell is then able to get the data of many meters from one central location without the need to enter all the flats and without further technical equipment (laptop..). -

GmbH, Stettiner Str. 38, D-33106 Paderborn Access by ID: The M-Bus Display support a different setup of the passcode mode from the menu „Display config. – Passcode mode“. If this mode is activated, the user (tenant) can make a readout limited to his own meter(s). After first key-press the tenant is requested to type in the ID (identification no.) of the required slave. - Page 10 GmbH, Stettiner Str. 38, D-33106 Paderborn Displayed data: The device only displays the most important data for reasons of easy interpretation and not to confuse the reading personell. Some meters offer actual and historical values, different tariffs and additional devices like pulse counters in a heat meter. The first row always shows the primary address and ID for a clear association of the data to the respective meter.
