Quick Product Introduction How do I transmit data? Send your data to the RXD pin on the module. Use the UART format with settings (19200, 8, 1, N, no flow control). Up to 1018 of payload bytes are buffered in the module (total 1024 including header bytes). The module will transmit the data when

the max packet length is reached
the unique end character is sent
the modem timeout limit is reached The packet length, end character and timeout limit are configurable in-circuit. How do I receive data? Any received data packet with correct address and check sum will be sent on the TXD pin using the same UART format as for transmit. 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. How do I change the RF channel or any other parameter? To change configurable parameters, assert the CONFIG pin, and send the command string using the same serial interface as for transmitting data. Parameters can be changed permanently and stored in non-volatile memory in the module.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 6 of 28 Radiocrafts Embedded Wireless Solutions Block Diagram Circuit Description The module contains a communication controller with embedded RC232™ protocol software, a high performance RF transceiver with an internal voltage regulator and a Power Amplifier. The communication controller handles the radio packet protocol, the UART interface and controls the RF transceiver. Data to be sent by the host is received at the RXD pin and buffered in the communication controller. The data packet is then assembled with preamble, start-of-frame delimiter (SOF), address information and CRC check sum before it is transmitted on RF. The preamble and SOF is always used. The address and CRC are optional. The RF transceiver modulates the data to be transmitted on RF frequency, and demodulates data that are received. Received data are checked for correct address and CRC by the communication controller. If the address matches the modules own address, and no CRC errors were detected, the data packet is sent to the host on the TXD line after removing the header. The asynchronous UART interface consists of RXD and TXD. Optionally CTS, RTS can be used for hardware handshake flow control. RXTX can be used to control the direction of an RS485 driver circuit. When the CONFIG pin is asserted the communication controller interprets data received on the RXD pin as configuration commands. There are commands to change the radio channel, the output power, the destination address etc. Permanent changes of the configuration is also possible and are then stored in internal non-volatile memory. The RF protocol and the configuration commands are described in detail in the RC232™ User Manual. The supply voltage is connected to the VCC pin. The module contains an internal voltage regulator for the transceiver.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 7 of 28 Radiocrafts Embedded Wireless Solutions RC232™ Embedded Protocol The module offers a buffered packet radio in the RC232™ embedded protocol. Using the buffered packet radio mode, all data to be sent is stored in the module before they are transmitted by the RF circuitry. Likewise, when data is received they are stored in the module before they are sent to the host. This allows the communication controller to add address information and to do error check of the data. In buffered mode the UART interface is used to communicate with the host. The embedded protocol, configuration commands and configuration memory is described in the RC232™ User Manual. This protocol is used in a wide range of RF modules available from Radiocrafts. Please refer to the latest revision available on Radiocrafts web-site. Power Management The module can be set in SLEEP mode in order to reduce the power consumption. The low power SLEEP mode is entered by using the SLEEP command ‘Z’ after the module is set in configuration mode, or by pulling RTS/SLEEP pin low. The SLEEP pin is default off and must be enabled in configuration memory before use. In sleep mode the module will not receive or detect incoming data, neither from the host (UART port) nor from the RF transceiver. The module is awakened from the SLEEP mode by a positive edge on the CONFIG pins if the module was set in SLEEP mode using the ‘Z’ command. The module is awakened by a positive edge on the RTS/SLEEP pin if this pin were used to enter SLEEP mode. CONFIG must be high when awakening the module to avoid setting the module directly in configuration mode. UART data on RXD to the module should be avoided in sleep mode. All configuration settings and RAM values are retained during Sleep. The pull-ups on RTS/SLEEP and CONFIG pin are disabled during sleep mode in order to minimise the sleep current consumption. If the module is shut completely off, all configuration settings in non-volatile memory is restored, but values in RAM are overwritten with default settings.

The IDLE state is the normal state where the module search for preamble on the air and wait for a character to be received on the UART. RXD is the state when receiving characters from the host filling up the internal buffer. TX state is when the data is transmitted on the air. RX state is when data is received from the air after preamble detection. TXD is the state where the received data is sent to the host on the UART. CONFIG is the state entered by asserting the CONFIG pin and used during parameter configuration, while MEMORY CONFIG is the sub-state entered by the ‘M’ command where the configuration memory is being programmed. Note the limitation on maximum number of write cycles using the ‘M’ command, see Electrical Specifications.

For channel 17 and 18 the maximum RF data rate is 1.2 kbit/s and +25 dBm output power due to limitations in modulation bandwidth at the 869.4-869.65 MHz band- edges. RF channel and output power level can be set using the configuration commands ‘C’ and ‘P’ respectively. The data rate can only be changed in configuration memory by using the ‘M’ command setting RF_DATA_RATE. The default RF channel and output power level can be set in the configuration memory by using the ‘M’ command setting RF_CHANNEL and RF_POWER. The default values are used after power ON and RESET. The default factory settings are shown in bold in the table above. For more details on changing the RF channel, output power or data rate, refer to the description of the configuration commands. The use of RF frequencies, maximum allowed RF power and duty-cycles are limited by national regulations. The RC1180HP-RC232 is complying with the applicable directives within the European Union when used within these limitations. The RC1170HP-RC232 is complying with the applicable directives in India when used within the local regulations for India. Multi-channel usage All modules from Radiocrafts embed a high performance transceiver which can transmit and receive on one out of several channels. It is clear that other transmitters present on the same channel at the same time can cause interference (from bit errors until no detection of the wanted signal) if they have a higher signal level from the non-friendly transmitter than the wanted signal present at the receiver. To avoid this, configure the radio to use the channel with least interference. At 868 MHz, radios are allowed to transmit only short bursts before leaving the channel free for other radios, thus the interference can be expected to be of short duration. Co-located radios Precautions have to be taken in a so-called co-location (also named collocation) operation of transceivers. This means reception and transmission at different channels at the same time with the intention that the two channels shall be able to operate without disturbing each other. As indicated in the figure above a module B is receiving a message from A on channel X while another module C is transmitting at the same time on another channel Y (a message intended for module D). As any radio device has a limited suppression of signals at any other channel, RX TX 27 dBm Ch. X Ch. Y TX 27 dBm RX Interference A B C D

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 12 of 28 Radiocrafts Embedded Wireless Solutions some power of the signal at the other frequency will enter into the receiver B. Normally, the suppression increases versus the frequency separation between the two channels. The phrase “adjacent” means the channel next to while the definition “alternate” means the channel(s) further apart. The ability of a receiver to reject any out-of-band interferer is named ACR, adjacent channel rejection. Friis formula and empirical adaptations of this predicts the path loss between a transmitter and a receiver. The path loss increases (1/R)n where R is the radius and n is between 2 and 5 and heavily depending on the surroundings. Knowing the TX output power, the path loss between A-B decides the amount of power entering the receiver B as well as the path loss between B-C decides the amount of interferer power entering the same receiver. If we assume there is identical antenna performance on A and C and they have identical output power it is clear that when the path loss A-B equals ACR then the interferer C can be placed in immediate proximity of B. As the path loss increases with from R2 to R5, C has to be moved further and further apart from B as the distance A-B increases (causing lowered received friendly signal power). At a distance when the signal power from A reaches the sensitivity level of B, C for all practical reasons has to be so far from B that simultaneous operation has very limited practical usage. Useful collocation operation is when we are well above the sensitivity level of B. Another important parameter for ACR is the selected RF data rate, as this parameter defines the receiver bandwidth and as such, the rejection of interference at a fixed frequency deviation. As the regulatory bandwidth for 500mW operation is limited, the channels have to be close in frequency, and it is not possible to have collocation combined with high data rate. Only data rate 1.2 kbps can be used in a collocated scenario, higher data rates must rely on a time-division channel usage and then on channel 13 only. The values for RC1180HP-RC232 are shown below. The RSSI value is read via the embedded detector and performance is measured with Radiocrafts Demo Boards equipped with quarter wave whip-antennas and inside an office building. Conditions: Data rate setting 1.2 kbps with GFSK modulation, operation on various channels and interferer continuously transmitting on another channel TX, 27 dBm Distance to interferer at given reception levels for friendly signal Channel 17 Channel 18 -60 dBm -80 dBm -100 dBm -60 dBm -80 dBm -100 dBm Ch. 13 3 m 20-25 m N/A 3 m 20-25 m N/A Ch. 17 X X X 1 m 10-12 m N/A Ch. 18 1 m 10-12 m N/A X X X General recommendations: Due to ACR versus channel bandwidth, collocation of equipment is not possible on other RF data rates than 1.2 kbps. Practical collocation can be done if the signal strength of the friendly channel is above -80 dBm.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 13 of 28 Radiocrafts Embedded Wireless Solutions RSSI Reading The module provides a digital Received Signal Strength Indicator (RSSI) through the ‘S’ command, or attached to received messages. The module returns an 8 bit character (one byte) indicating the current input signal strength (followed immediately by a second character which is the prompt (‘>’) when in command mode). The signal strength can be used as an indication of fading margin, or as a carrier sense signal to avoid collisions. The signal strength measure by the S command is the instantaneous value. The RSSI value appended to a received message (RSSI_MODE = 1) is the signal strength of that received packet. The RSSI value increases with increased input signal strength in 0.5 dB steps. Input signal strength is given by (typ.): P = - RSSI / 2 [dBm] Temperature Reading The module provides readings of an internal digital temperature monitoring sensor (TEMP) through the ‘U’ command. The module returns an 8 bit character (one byte) indicating the current temperature in degrees Celsius (°C) followed immediately by a second character which is the prompt (‘>’). The TEMP value increases with increased temperature in 1 °C steps and accuracy of +/- 2 °C. Temperature is given by: T = TEMP(dec) - 128 [°C] (example: TEMP=0x98 equals +24 °C) Power Supply voltage Reading The module provides readings of an internal power supply voltage monitoring sensor (VCC) through the ‘V’ command. The module returns an 8 bit character (one byte) indicating the current power supply voltage level followed immediately by a second character which is the prompt (‘>’). The command can be useful for battery power monitoring. The VCC value increases with increased power supply voltage in 30 mV steps. The power supply voltage is given by: V = VCC(dec)*0.030 [V] (example: TEMP=0x68 equals 3.12 V)

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 14 of 28 Radiocrafts Embedded Wireless Solutions Module Configuration The configuration of the module can be changed in-circuit from the host during operation, at the time of installation of the equipment, at the manufacturing test, or even as a standalone module. The configuration is changed sending commands on the UART interface after the module is set in configuration mode. The configuration mode is entered by asserting the CONFIG pin (set low). In command mode the module will respond by sending a ‘>’ prompt on the TXD pin. This indicates that the module is ready to receive commands. The CONFIG pin can then be de- asserted. Note that the CONFIG pin must be de-asserted before the Exit command (‘X’) is sent to the module in order to return to normal operation. After a command is executed, the module responds with the ‘>’ prompt character again indicating it is ready for a new command. Do not send a new command before the ‘>’ prompt is received. The time required to execute a command can vary depending on the command (see the Timing Information section). There is no ‘>’ prompt after the ‘X’ exit command. The parameters that are set by commands directly take immediate effect after returning to normal operation (IDLE), but will not be stored in non-volatile memory, and will be lost in case the supply power is turned off or if the module is reset. These parameters are for example the radio channel and output power. A list of commands is shown in the table below with typical values for RC1180HP-RC232. Parameter Command Argument in hex (decimal) Note Channel ‘C’ – 0x43 RC1170HP: 0x01-0x0F(1-15) RC1180HP: 0x01-0x12(1-18) RC1190HP: 0x01-0x32(1-51) Data is stored in volatile memory only. For variants not listed here, refer to the specific data sheet. Output power ‘P’ – 0x50 0x01-0x05 (1-5) Data is stored in volatile memory only. Signal Strength (RSSI) ‘S’ – 0x53 Returns one byte indicating the signal strength Destination address ‘T’ – 0x54 0x00 – 0xFF (0-255) Data is stored in volatile memory only. Note! If ADDRESS_MODE = 8, the T-command will take 4 address bytes as input. It will reply with the prompt character between each byte. Temperature monitoring ‘U’ – 0x55 Returns one byte indicating the temperature. See page 13 for details Battery monitoring ‘V’ – 0x56 Returns one byte indicating the power supply voltage. See page 13 for details Memory configuration ‘M’ – 0x4D (Address, Data): see list of parameters below. 0xFF exits memory configuration. Used to enter memory configuration menu. Parameters changed are stored in non-volatile memory. Memory Reset ‘@RC’ No arguments, but CONFIG must be asserted low during this command. Resets the configuration memory back to factory default values in the whole non-volatile memory.

A table of ASCII characters and their respective hex and decimal values are found in the Appendix. Note: Test mode 2 is used to achieve 100% duty cycle. Can be used for example for certification tests. Commands must be sent as ASCII characters or their corresponding binary value. All arguments must be sent as binary values to the module (not as ASCII representation for hex or decimal). Any invalid command will be ignored and the ‘>’ prompt will be re-sent. The CONFIG line must be de-asserted after the first ‘>’ prompt was received, but before the ‘X’ command. To make permanent changes to default values and other parameters, the Memory Configuration command ‘M’ is used. This command should be followed by pairs of byte being the memory address and the new value to be stored at that address. In order to exit the Memory Configuration mode command ‘X’ must be sent. Example: To select RF channel 3, send the follow sequence after asserting the CONFIG line and the ‘>’ prompt is received: Command Hex Response Comment/Note CONFIG asserted ‘>’ De-assert CONFIG after ‘>’ prompt ‘C’ 0x43 ‘>’ 3 0x03 ‘>’ Wait for ‘>’ prompt [A new command could be issued here] ‘X’ 0x58 (none) Module returns to IDLE state It is important to enter Test mode 3 before exiting the configuration mode (‘X’) if Test mode 1 or 2 has been used. This will ensure proper operation in normal mode.

Antenna Connection The antenna should be connected to the RF pin. The RF pin is matched to 50 Ohm. If the antenna connector is placed away from the module at the motherboard, the track between the RF pin and the connector should be a 50 Ohm transmission line. On a two layer board made of FR4 the width of a microstrip transmission line should be 1.8 times the thickness of the board, assuming a dielectric constant of 4.8. The line should be run at the top of the board, and the bottom side should be a ground plane. Example: For a 1.6 mm thick FR4 board, the width of the trace on the top side should be 1.8 x 1.6 mm = 2.88 mm.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 18 of 28 Radiocrafts Embedded Wireless Solutions The simplest antenna to use is the quarter wave whip antenna. A quarter wave whip antenna above a ground plane yields 37 Ohm impedance and a matching circuit for 50 Ohm are usually not required. A PCB antenna can be made as a copper track where the ground plane is removed on the back side. The rest of the PCB board should have a ground plane as large as possible, preferably as large as the antenna itself, to make it act as a counterweight to the antenna. If the track is shorter than a quarter of a wavelength, the antenna should be matched to 50 ohms. The lengths of a quarter wave antenna for different operational frequencies are given in the table below. Frequency [MHz] Length [cm] 865-868 8.2

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 19 of 28 Radiocrafts Embedded Wireless Solutions PCB Layout Recommendations The recommended layout pads for the module are shown in the figure below. All dimensions are in thousands of an inch (mil). The circle in upper left corner is an orientation mark only, and should not be a part of the copper pattern. A PCB with two or more layers and with a solid ground plane in one of the inner- or bottom layer(s) is recommended. All GND-pins of the module shall be connected to this ground plane with vias with shortest possible routing, one via per GND-pin. On the back side of the module there are several test pads. These test pads shall not be connected, and the area underneath the module should be covered with solder resist. If any routing or vias is required under the module, the routing and vias must be covered with solder resist to prevent short circuiting of the test pads. It is recommended that vias are tented. Reserved pins should be soldered to the pads but the pads must be left floating. Note that Radiocrafts technical support team is available for schematic and layout review of your design.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 21 of 28 Radiocrafts Embedded Wireless Solutions Soldering Profile Recommendation JEDEC standard IEC/JEDEC J-STD-020B (page 11 and 12), Pb-Free Assembly is recommended. The standard requires that the heat dissipated in the “surroundings” on the PCB is taken into account. The peak temperature should be adjusted so that it is within the window specified in the standard for the actual motherboard. Aperture for paste stencil is normally areal-reduced by 20-35%. A nominal stencil thickness of 0.1 – 0.12 mm is recommended. Consult your production facility for best experience aperture reduction. Cleaning and welding Recommendation Ultrasonic processes like ultrasonic cleaning and ultrasonic welding to assemble plastic enclosures can cause deterioration or destruction of components inside the module. Please avoid ultrasonic processes on products that include any of the RC11xxHP module variants in the design.

write cycles using the ‘M’ command is limited Regulatory Compliance Information The use of RF frequencies and maximum allowed RF power is limited by national regulations. The RC1180HP-RC232 has been designed to comply with the RED directive 2014/53/EU. According to RED directives, it is the responsibility of Radiocrafts’ customers (i.e. RC11XXHP- RC232 end user) to check that the host product (i.e. final product) is compliant with RED essential requirements. The use of a CE marked radio module can avoid re-certification of the final product, provided that the end user respects the recommendations given by Radiocrafts. A Declaration of Conformity is available from Radiocrafts on request. The relevant regulations are subject to change. Radiocrafts AS do not take responsibility for the validity and accuracy of the understanding of the regulations referred above. Radiocrafts only guarantee that this product meets the specifications in this document. Radiocrafts is exempt from any responsibilities related to regulatory compliance.

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 24 of 28 Radiocrafts Embedded Wireless Solutions Application circuit A typical application circuit is shown where a MCU is connected to the Radiocrafts module. In normal cases the UART (CTS/RTS is optional) and RESET line is connected to a host MCU running the application. CONFIG pin is needed to set the RC232 modules into configuration mode. Pin 29/30 are LED drivers and D1/D2 can be mounted (optional) for debugging (State information). MCU considerations Some additional external components is needed depending on MCU output driver properties connected to the Radiocrafts module. If the RESET is driven by a push-pull output, an additional 0 ohm series resistor (R4) shall be inserted as shown in the figure, to allow an external programmer used for firmware upgrade to assert Reset low. During firmware upgrade, R4 must in this case be removed. In noisy surroundings and where RESET is not driven by a push-pull output, it is recommended to add an external pull-up on RESET using a 5k6 resistor (R3). If the pull-up is stronger the external programmer used for firmware upgrade will not be able to assert RESET low. In noisy surroundings and where RXD is not driven by a push-pull output, it is recommended to add an external pull-up on RXD using a 5k6 resistor (R3).

©2019 Radiocrafts AS RC11XXHP-RC232 Data Sheet (rev. 1.1 1) Page 25 of 28 Radiocrafts Embedded Wireless Solutions Reset filter To minimize effect of noise on the Reset-line, the RESET pin on the module (pin 12) must be connected to an external circuitry via an RC-network. It is recommended to connect RESET to a microcontroller I/O-pin. The reset filter should be placed as close as possible to the RESET pin of the module. Power Supply Noisy external circuitry may under certain scenarios affect the transmitted signal on RX1180-RC232 and precaution should be taken for EU RED conformity. Example of circuits that can generate noise on the RC1180-RC232 transmitted spectrum may be DC/DC converters and some level converters like RS232 and RS485. To increase spectrum margin it is important to add an EMI filter bead (L1) on the VCC pin of the RC1180-RC232 module. Alternatively, the RC1180-RC232 may be powered (RC_VCC) from a separate voltage regulator. This will ensure that potential switching noise is filtered out from the power supply (RC_VCC) to the RC1180-RC232. Component Manufacturer Part number EMI filter bead (L1), 1500 mA Murata Ordering code BLM18SG331TN1 Programming Interface For future firmware updates and possible custom variants it is recommended to include a 2x5 pins programming connector to the module programming pins. The connector should be a 1.27 mm pitch pin-row (same pitch in both directions), SMD or through-hole version, with the connections shown below. RXD/TXD lines is not in use for firmware upgrade, but is included on spare pins on the connector for debugging purposes.
