MBUS USER MANUAL
1.2 Differencies between RC11xx and RC17xx series
This User Manual describes the embedded protocol of the Wireless M-Bus modules from Radiocrafts. The MBUS
firmware is available as different feature sets targeting specific applications. The hardware has the same size and
pin-out for all frequency versions, and the different feature sets available are listed in the table below. The feature
sets and the embedded functions are independent of the frequency, so this User Manual is valid for all versions
RC11xx(HP)-MBUS3 and RC1701HP-MBUS4. Detailed information on how to use the different feature sets is
found in this User Manual. Additional information about the Wireless M-Bus packet structure for NTA 8130
compliance is described in Application Note 011 and is available on request.
