## **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 of 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. 

## **RCTools**

## **Circuit Description** 

The module contains a communication controller with embedded RC232™ protocol software, a high performance RF transceiver and an internal voltage regulator. 

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 and can therefore operate over a wide supply voltage range.

## **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. 

When the SLEEP pin is not enabled (RF_SLEEP_MODE = 0x00) the module can be set in Sleep mode by activating CONFIG and sending a ‘Z’ command. The module is woken up when CONFIG is deactivated (goes high). Note: During Sleep the CONFIG pin does not have any internal pull-up, so the CONFIG pin must be driven high in order to wake the module. Any activity on the RXD pin will make the module wake up, but immediately return to Sleep as long as CONFIG is kept low. Such activity on the RXD pin should be avoided in order to reduce current consumption. 

When the SLEEP pin is enabled (RF_SLEEP_MODE = 0x02) the module can be set in Sleep mode by activating RTS/SLEEP (asserting low). The module is woken up when RTS/SLEEP is deactivated (goes high). Note: During Sleep the RTS/SLEEP pin does not have any internal pullup, so the RTS/SLEEP pin must be driven high in order to wake up the module. Any activity on the RXD or CONFIG pins will not make the module wake up. Activity on module pin 16 and 17 can wake the module and must be avoided (do not connect, as previously stated in this document). CONFIG must be high when awakening the module to avoid setting the module directly in configuration 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.

## **Timing Information** 

The figure and table below shows the timing information for the module when changing between different operating states. 

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.

_* Not recommended due to higher output power than the FCC limit._ 

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 channels 1, 6, 7, 12, 14 and 16 the maximum RF data rate is 19.2 kbit/s due to limitations in modulation bandwidth at the given sub band-edge. 

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 RC1180-RC232 and RC1140-RC232 is complying with the applicable directives within the European Union when used within these limitations. 

RC1190-RC232 is pending approval under FCC for use in the US and Canada. For more information see section “Regulatory Compliance Information”.

## **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] 

The dynamic range of the RSSI (P) goes from the Sensitivity level up to typical -30 dBm (RSSI saturation level). 

## **Temperature Reading** 

The module provides readings of a 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: VCC=0x68 equals 3.12 V)

## **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 deasserted. 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. 

|**Parameter **<br>~~e_~*7F~~|**Command**<br>~~e_~*7F~~|**Argument in hex (decimal)**<br>~~e_~*7F~~|**Note**<br>~~e_~*7F~~|

_Note:_ ASCII characters are written as ‘X’, hexadecimal numbers are written like 0x00, and decimal numbers are written like 10 throughout the text. A table of ASCII characters and their respective hex and decimal values are found in the Appendix. 

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.

_**Note:** Address location not listed should not be changed from the default value._ 

## **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.

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**<br>**[MHz]**|**Length**<br>**[cm]**|
|---|---|
|433|16.4|
|865-867|8.2|
|868|8.2|

## **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.

## **Regulatory Compliance Information** 

The use of RF frequencies and maximum allowed RF power is limited by national regulations. The RC1140-RC232 and RC1180-RC232 has been designed to comply with the R&TTE directive 1999/5/EC. According to R&TTE directives, it is the responsibility of Radiocrafts’ customers (i.e. RC11XX-RC232 end user) to check that the host product (i.e. final product) is compliant with R&TTE 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 RC1190-RC232 has been tested towards FCC regulations for license free operation under part 15. However, a final approval is required by FCC for the end product. 

The RC1170-RC232 has been tested towards G.S.R.564(E) and G.S.R.168(E) for license free use in India. The Gazettes are available from Radiocrafts on request.

## **Power Supply** 

Noisy external circuitry may under certain scenarios affect the transmitted signal on RC11XX-RC232 and precaution should be taken for EU R&TTE conformity. Example of circuits that can generate noise on the RC11XX-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 on the VCC pin of the RC11XX-RC232 module. Alternatively the RC11XX-RC232 may be powered form a separate voltage regulator. This will ensure that potential switching noise is filtered out from the power supply to the RC11XX-RC232. A block diagram of a typical PC serial port interface is illustrated below. 

Suggested part numbers: 

**Component Manufacturer Part number** EMI filter bead Murata BLM11A102S, ordering code ~~Se~~ BLM18xx102xN1D 

## **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 2.54 mm pitch pin-row (same pitch in both directions), SMD or through-hole version, with the connections shown below. 

## **Reset connection** 

To minimize effect of noise on the Reset-line, the Reset pin on the module (pin 12) must be connected to external circuitry via an RC-network. It is recommended to connect Reset to either a supervisory circuit or microcontroller I/O-pin. If the Reset is driven by a push-pull output, an additional series resistor of 5k6 shall be inserted as shown in the figure, to allow an external programmer used for firmware upgrade to assert Reset low. In noisy surroundings and where Reset is not driven by a pushpull output, it is recommended that the connection ‘A’ below is pulled to VCC via one or more resistors where the equivalent pull-up resistor is close to 5k6
