USER MANUAL RC1701HP-MPC1
1 Introduction
1.1 Quick Start
The MPC module is intended to be used as a Wireless M-Bus slave node, transmitting data from any meter (like
gas-, water-, heat- or electricity meter), transmitting messages that can be received by any standard Wireless M-
Bus receiver, like the Radiocrafts RC11x0-MBUS3 and RC17xx–MBUS4, acting as Master in the system. The
meter(s) needs to be connected to the MPC module’s PULSE1 or PULSE 2 (or both) inputs. The module is
normally in sleep mode with ultra-low power consumption, only counting and accumulating pulse inputs when the
PULSE1/PULSE2 inputs goes low or high. At a configurable interval, the module wakes up and makes an RF
transmission of the accumulated value. The module can also be used without pulses to the pulse counter input and
will then act as a general ID- and status transmitter.
How do I configure the MPC1 module?
The module has a UART interface which is used for initial setup of the module. For available commands and
configuration parameters –please see Appendix A and Appendix B.
As part of the initial setup, you can enable Over The Air (OTA123) configuration. This is described further in
chapter 8.
What about the antenna?
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.
Radiocrafts also offer an application note on tuning a 169 MHz antenna in AN025, found here:
https://radiocrafts.com/resources/application-notes/
Examples
The Appendix D of this user manual contains examples of how to perform various configurations.
1.2 Comparing MPC1 and MBUS3/MBUS4 modules
The RC1180-MPC1 and RC1701HP-MPC1 modules are buildt on the RC1180-MBUS3 and RC1701HP-MBUS4
modules respectively. However –they are enhanced to work as autonomous slave units without the need for an
external MCU.

2 Wireless M-Bus Embedded Protocol
During the RF transmission, the module transmits a data frame according to EN13757-3/4. At the MBUS receiver,
the format of the payload will look like this:
Figure 1 –Wireless M-Bus Packet
L
Added automatically. Does not include itself, nor START/STOP bytes.
C
Configured in module. Added automatically.
HEADER
Configured in module. Added automatically.
CI
Configured in module. Added automatically.
APPL_DATA
Application data including packet counter, tamper info and pulse counting values for
the two inputs (4 bytes for each pulse input). Added automatically.
The MPC1 module will transmit the data points using the M-Bus application protocol (EN 13757-3). The type and
number of data points included in the message depends on the configuration of the module (one or two pulse
inputs). The DIF and the VIF are the descriptors used.
A “short header” (transport layer) is used for status and encryption information. The STATUS byte contains the
battery alarm bit (0x04) and tamper bit (0x20). The tamper monitoring is enabled through the module configuration.
To fully understand the protocol and details like packet format, configuration, sleep modes and so on for a
complete Wireless M-Bus setup, please refer to the Data Sheet and the User Manual for RC1xx0-MBUSx found on
the Radiocrafts website www.radiocrafts.com.

Connect to the UART interface with these settings:
•Baud rate: 19200
•Data bit: 8
•Stop bit: 1
•Parity control: None
•Flow control: None
3.1 Set the MPC1 module in CONFIG mode
The MPC1 module is in sleep mode between each transmission, so to enter CONFIG mode you need to first send
0xFF to wake it up, then send 0x00 to enter config mode.

4 Set up and use the pulse inputs
The meter pulse inputs (PULSE1/PULSE2) of the module is between GND and Pin 27/28. These are the same
input as Push Button S5/6 on the Development Board for the module. MPC_IO can enable one or two pulse inputs.
The pulse is counted on negative or positive edge. This is configurable by the configuration parameter
MPC_POLARITY.
The input has configurable pull-up internally to avoid leakage current during pulse (input = 0V). This means the
external circuitry must keep the pin high to ensure no leakage. In case the pulse is generated by an open / short to
ground circuitry, a pullup to VCC is needed. You can choose between adding an external 1MOhm (mega-ohm)
resistor or enabling an internal pullup set by configuration parameter MPC_PULLUP. Adding the external pullup will
give a lower current consumption.
Figure 2 –Pulse Pin connection
C1 together with R1 can be used to filter the pulse input, but do not use too much filtering as this will reduce the
rise/fall time of the pulse.
If the UART is not connected to any circuitry during operation, make sure to include a pull-up resistor to RXD. Data
to this pin will wake up the module from sleep.
R1 ~0-10k ohm

5 Set up and use the Installation pin
INSTALL can be enabled by setting configuration parameter MPC_IO, and the polarity of INSTALL is set by
configuration parameter MPC_POLARITY. You can also enable an internal pullup for INSTALL in the same way as
it can be done for other inputs. This is enabled by configuration parameter MPC_PULLUP.
When INSTALL is enabled as described above, and it is activated - the MPC will start the transmission of
installation request messages (SND-IR) with CI = 0x7A, no application data. The module will send a new SND-IR
message every 30-60s until installation mode is exited (see below) or it reaches it’s maximum number of
retransmissions (totally 90 messages).
If INSTALL is activated again, the module exits installation mode, terminates the SND-IR transmissions and return
to sleep mode (normal operation).
The module does not expect, or listen for, an Installation confirmation (CNF-IR)
The installation request message will be:

6 Set up and use the Tamper pin
The Tamper pin can be enabled by setting configuration parameter MPC_IO, and the polarity of the tamper
function is set by configuration parameter MPC_POLARITY. You can also enable an internal pullup for the Tamper
pin in the same way as it can be done for other inputs. This is enabled by configuration parameter MPC_PULLUP.
When the Tamper pin is enabled as mentioned above, and the Tamper pin is activated the MPC module will set the
alarm bit in the STATUS byte of the next message. The STATUS byte is found in the transport layer header.

7 Set up and use encryption
The module supports security mode 5, using AES-128-CBC encryption.
The ENCRYPT_FLAG and DECRYPT_FLAG parameters are used to set the flags to enable / disable the
encryption when transmitting and receiving messages.
The 16 byte encryption key is set as part of the configuration memory and can be configured either by UART or
OTA123.
Example 1 –Set encryption key via UART

8 Set up and use OTA (Over The Air) Configuration
If the configuration parameter MPC_IO enables the CONFIG pin, an interrupt is used to send the current
configuration data in an SND-NR (C=0x44) message, and listen for a configuration message. The configuration
message from the gateway to the MPC can be either SND-UD (C=0x43) or SND-NR. The length of the listening
window can be configured by the configuration parameter PACKET_TIMEOUT.
Every time you pull the CONFIG pin low, the MPC1 module goes through the below process automatically:
Figure 3 –OTA123 flow
For a normal OTA123 update-cycle you will go through the above flowchart 3 (or 4) times:
Step 1: When CONFIG is activated the current configuration memory is sent from the MPC in an SND-NR
message using CI = 0xAA. Application data is the full dump of the configuration memory. The MPC1 is listening for
an SND-UD message, but will time out and go back to sleep.
Step 2: The MPC will also this time send an SND-NR message with the configuration memory. The gateway must
now be set up to respond to this message with an SND-UD message (SND-NR also accepted). The SND-UD
message can be formatted in two ways, leading to different actions on the MPC:
1. CI = 0xAB. The application data must contain the updated configuration parameters. You can send only the
bytes changed or the full configuration memory. When the MPC receives this message it will update
configuration memory accordingly.
2. CI = 0xAC. The application data is not read by the MPC. Module will reset.
Step 2 must be ran twice if the configuration parameters updated needs a reset to take effect, first with CI=0xAB,
then with CI=0xAC.
Step 3: This step is optional, but since the MPC sends the configuration memory in an SND-NR message when the
CONFIG pin is activated, then this can be used to read back the configuration after the update to confirm that the
result is as expected.
Warning!: If some of the configurations are changed un-intentionally to illegal values, it can set the module
into a not recoverable, nonworking condition. Currently there is no filter on permitted values.
Note! The module does not support encrypted messages for the OTA123 update procedure.
