FreePad and Interface Module Description1/5 FreePad and Interface Module – Application General Circuit Description The FreePad RF Remote Control and the RF Interface Module are part of a complete Spa System. Spa Electronic Controller: This Spa System uses a Spa Electronic Controller which is a black box located under the skirt of a spa. The Spa Electronic Controller provides power to all the pumps, heaters, blower, temperature probe and the like of the spa system. To do so, the Spa Electronic Controller has microcontroller based control circuits for timer, temperature regulation, pump and other control functions. Spa System Freepad RF Remote Control RF Interface Module Spa Electronic Controller Supply dc I2C Link Pump #1 Pump #2 Other Accessories Spa system using the FreePad RF Remote Control and the RF Interface Module FreePad and Interface Module Description2/5 FreePad RF Remote Control: The FreePad RF Remote Control is the user interface that sends commands to the Spa Electronic Controller and that receives status information from the Spa Electronic Controller. It does so through RF Communication. The FreePad RF Remote Control electronic circuit is located inside a plastic housing. There is two separated Printed Circuit Boards (PCB) in this housing. The first PCB is the RF PCB. This is where all RF communication functions are located. The RF PCB is mounted over a second PCB, which is the Control Board. This control board comprises batteries, keypad, LCD and a μController. It is this Control Board that controls the power supply, the keypad, the LCD and that manages the input/output data exchange between the μController and RF PCB. These exchanges of input/output data are done through a 34 Kbaud, 8bits serial link. FreePad RF Remote Control Control Board Power Supply Batteries μController LCDKeypad 34 KBaud 8 Bits Serial RF PCB Transceiver Antenna FreePad and Interface Module Description3/5 The RF Interface Module: The RF Interface Module is the electronic circuitry that translates the RF communication data stream (from/to the FreePad RF Remote Control) to a low frequency digital data stream from/to the Spa Electronic Controller. The RF Interface Module is located inside a plastic box. This plastic box is connected to the Spa Electronic Controller through a 4 wire cable that provide a +5Vdc supply and the I 2 C serial communication link. There is two separated Printed Circuit Boards in this RF Interface Module housing. The first PCB is the RF PCB. This is where all RF communication functions are located. This is the exact same RF PCB as with the FreePad RF Remote Control. It has the same PCB, same layout, same components and same onboard antenna. As with the FreePad, the RF PCB is mounted over a second PCB, which is the Interface Module Control Board. This Interface Module Control Board has only one function. It communicates with the RF PCB through the 34 Kbaud, 8bits serial link and translates this data stream to the I 2 C serial communication link that connects to the Spa Electronic Controller. RF Interface Module 34 KBaud 8 Bits Serial RF PCB Transceiver Antenna Interface Module Control Board μController I2C Link Spa Electronic Controller FreePad and Interface Module Description4/5 The RF PCB: The RF PCB uses a transceiver. This transceiver is a monolithic integrated circuit used as a low cost FM transceiver. It is the RF2095 from RF Micro Devices, Inc. (Greensboro, NC27409). This device is provided in 7mmx7mm, 48-lead plastic LQFP packaging and is designed to provide a fully functional FM transceiver. The chip is intended for digital FSK applications in the North American 915MHz ISM band. The integrated VCO, dual modulus/dual divide 128 prescaler, and reference oscillator require only the addition of a external crystals to provide a complete phase-locked oscillator. The crystals that are used are 7.07549MHz, 7.15909 MHZ and 10.7MHz The RF PCB specification are as following: Voltage of Operation:5V dc Power Consumption:Rx mode: 8 mA typ. Tx mode: 25 mA typ. Frequency of operation : 916 MHz Typical Transmission power:1mW Transmission Type:25 to 100 ms digital packets. Encoding: Manchester Digital data rate: 34.7 K bauds Operating Temperature:0 to 70 °C (32 to 160 °F) This RF2905 has been implemented in a 15GHz silicon bipolar process technology that allows low-power transceiver operation in a variety of commercial wireless products. In its basic form, the RF2905 can implement a two-way half duplex FSK transceiver with the addition of some crystals, filters, and passive components. There are two reference crystals that allow for the transmit carrier and the receiver LO to be independently generated with a common PLL and VCO. The receiver IF section is optimized to interface with low cost 10.7MHz ceramic filters but has a -3 dB bandwidth of 25MHz and can still be used (with lower gain) at higher frequency with the other type of filters. The PA output and LNA input are available on separate pins and are designed to be connected together through a DC blocking capacitor. In the Transmit mode, the PA will have a 50Ω impedance and the LNA will be a high impedance. In Receive mode, the LNA will have a 50Ω interface and the PA will have a high impedance. This eliminates the need for a TX/RX switch and allows a single RF filter to be used in transmit and receive modes. Separate access to the PA and LNA allow the RF2905 to interface with external component such as higher power PA’s, lower NF LNA’s, up converters, and down converters for a variety of implementations. FreePad and Interface Module Description5/5 FSK SYSTEM The MOD IN pin drives an internal varactor for modulating the VCO. This pin is driven with a voltage level needed to generate the desired deviation. A resistor divider network referenced to Vcc divides down logic level signals to the appropriate level for the desired deviation in FSK systems. On the receiver demod, two outputs are available, an analog FM output and a digital FSK …

RR#5 Ottawa, Ontario K1V 1H2 Canada Obj:FCC Letter about FreePad and Interface Module Same Radio Circuit Dear Ruby: Both the FreePad Remote Control and the Interface Module use the exact same Radio Circuit. This Radio Circuit is built on a RF Printed Circuit Board (RF PCB) that uses the same RF components (including an onboard PCB soldered antenna) for all Radio transmission and reception purposes. In the FreePad remote control, the Radio Circuit PCB is screwed over a “power supply and LCD PCB” that regulates the voltage provided by a set of batteries. This FreePad’s power supply PCB also controls the LCD display and the keypad. In the Interface Module, the exact same Radio Circuit PCB is screwed over a “power supply PCB” that regulates the voltage provided by an external (wire connected) power supply. This external power supply is generated by the Spa Electronic Controller. In the Interface Module, the power supply PCB (on which the Radio Circuit PCB is screwed) does not provide LCD, nor keypad function. So, everything related to RF communication is done only by the Radio Circuit PCB. Both the FreePad Remote Control and the Interface Module use this Radio Circuit PCB. Best Regards, Louis Nollet, Eng.
