    In most cases a simple quarter wavelength wire or a PCB track will do. Connect a piece of wire to the RF pin with length corresponding to the quarter of a wavelength. For space limited products, contact Radiocrafts and we will recommend the best antenna solution for your application.

    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.

    TXD line. When the host MCU wants to transmit a Wireless M-Bus packet over the RF, it must send the packet through the UART interface on the RXD line. Figure 2 – Wireless M-Bus Link Page 7 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

    Slaves. In the standard the Master is referred to as “Other”. The Radiocrafts Wireless M-Bus family of modules can be configured to have a role as either Master or Slave. The Slave contains a unique address, and when sending a meter reading this address is added to the wireless message.

    The destination address (or module address) can also be changed using the ‘T’ command. Using the ‘T’ command, the address is not stored in non-volatile memory. To do a permanent change, use the ‘M’ command. Page 14 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

  • Page 21: Power Management

    What determines the battery lifetime is how much time the module spends in the modes where current consumption is “high”. The Radiocrafts modules offers several configuration options to allow the module to be “off” for an extensive part of the time: Manual SLEEP function (‘Z’-command from config mode)

  • Page 22: Power Cycling

    It is not recommended to turn off the module as an alternative to using SLEEP mode. The combination of very low SLEEP current and fast startup gives a lower overall current consumption. Page 21 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

  • Page 23: Installation And Binding

    Host MCU has control over which installation addresses that are available and decides on which Installation address to install the slave. The host MCU sends a Bind command (‘B’) to Radiocrafts module with installation address and slave address. The host MCU sets INSTALL_MODE = 0x00 (Filter on).

  • Page 26: Encryption And Decryption

    If both Link Layer encryption and Transport Layer Encryption is defined – LinkLayer encryption will be used. The ELL encryption mode 1, uses the counter mode (AES-128-CTR) and does not need any padding of data. Page 25 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

  • Page 27: Transport Layer Encryption

    The ‘E’ command can be used to encrypt a message in the Mailbox before it is sent. This is done to save time and needs to be done in T2-mode if the message to be sent back via the mailbox is more than one block. Page 26 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

    There are up to 15 mailboxes that can be used to store “pre-cooked” messages. Each mailbox is 64 bytes, except mailbox number 15 which is 128 bytes. Mailboxes can be combined to support messages up to 255 bytes (less the Page 32 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)

  • Page 35: Automatically Reply With Message From A Mailbox

    The N2 timing includes a response time of 100 ms (fast) or 1100/2100 ms (slow) after the Slave message is received. This timing is handled by the Master module. Also, a sleeping Slave will wake up and listen after this response time. Page 34 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)
  • Page 36 If a message is sent to the module during the response time cycle that does not match the last incoming message address, the response time cycle is terminated and the message is sent as a normal message without further time delay.

    In MBUS3 it is possible to choose to filter messages to be repeated by manufacturer identification code (MAN_ID). This is done by setting the configuration parameter REPEATER_MAN_ID[2:1]. The filtering function is off by default (REPEATER_MAN_ID[2:1] = 0x00 0x00). Page 39 of 60 ©2019 Radiocrafts AS MBUS User Manual (ver 2.01)
