Communication forms:

Stnadart communication interface is MBUS module, otptionally plugged afret opening upper case with screw with montage seal. Power source 3V Li battery. Communication connector is current protected, that's why it's impossible obtain current biger that 5 mA from meter's battery..
Komunikačný protokol je štandartný MBUS protokol. Communication protocol is standart MBUS protocol. Meter react only on its own address, which can be setted after plugin communication module. After plugin communication module is automatically called set-up of MBUS address, baud rate, in case of pulse registering weight and base offset of pulses too. It is possible set address 254. Setup is provided by button and displey.

Namely this characteristics of meter CF50 caused development of micro-programable language for definition of communication with meters. Normally is not here possibility, how can UniMeterRadio module know, which address meter has, only 'manual' setings of communication parameters. If we want do it, from universality we destroy very big part. Altough noted possibility here is for future by the form of download specified configuration of EEPROM, we decide not retreat and go by hard way - construct MBUS scanner directly to UniMeterRadio module. This scanner try communicate with meter at all possible baud rates and through the all possible addreses, so sonn or later meter must answer (if it is physically correct conected) and UniMeterRadio module can set-up and remember actual communication parameters. "Last success" communication parameters serve to any future communication with meter (without needing of again scann) CF50, or any other meter with the same MBUS characteristics.
