It is also available in the Indian licence free 865-867MHz band (General telemetry and RFID). Figure 1: FPX3-869-20 Features Conforms to ETSI EN 300 220-3 and EN 301 489-3 Conforms to Indian low power requirements for 865 - 867 MHz band High performance PLL synthesizer +26dBm RF power output Data rates up to 20 kbps for standard module Usable range over 3km Fully screened. Low profile Feature-rich interface (RSSI, analogue and digital baseband) Re-programmable via RS232 interface Applications Asset tracking systems Industrial telemetry and telecommand High performance security system Fire alarms ROV control applications High speed data modems Technical Summary Operating frequency: 868 – 870MHz (EU), 865 - 867MHz (India) Maximum of 8 channels (depends on band allocation and data rate) Transmit power: 400mW (+26dBm) nominal Supply range: +5V regulated Current consumption: 500mA (at 400mW output) transmit, 50mA receive Data bit rate: 20kbps max. (standard module) Receiver sensitivity: -115dBm for 12dB SINAD (20kbps variant) -117dBm for 12dB SINAD (10kbps variant) Size: 67 x 30 x 12mm Evaluation Platform: Narrow Band Evaluation Kit Radiometrix Ltd page 1 FPX3 Data Sheet Figure 2: FPX3 block diagram Radiometrix Ltd page 2 FPX3 Data Sheet Figure 3: FPX3 footprint (Top) view Pin Description Pins RF 1A 2A 3A Normal mode NO PIN RF in/out RF Gnd To the antenna RF ground 4A 5A 6A User 1 2 GND GND Vcc (TX) 0V 0V +5V regulated supply for TX 7 TXD TXE 3 4 5 6 7 8 9 10 11 GND Vcc P3 P2 P1 PGM in RSSI RXD AF out DC coupled input for 5v pp CMOS logic waveforms Transmit enable.

DC coupled, approx 0.8V bias NOTES: 1. No inversion occurs between TXD and RXD. 2. P1 - P3 (parallel channel selects) and N_TXE are active LOW and have internal 47K pullups to 4v 3. RXD is an open collector output, with a weak pullup to 4v (approx 50K) 4. This radio has no 'internal modem' functions in this version. 5. Programming port (P0) operates at 2400 baud. (Command set specific to this design). The unit is capable of operating in 'basic' parallel channel select only mode, or in serial controlled 'expanded' mode 6. The high current (500mA maximum) transmitter supply (5v regulated) is fed to a separate pin, on the RF out connector. The V supply (pin 4 on the user connector) also requires a 5v regulated supply, and draws up to 50mA Both pins must be supplied at all times (most users connect them to a common +5v supply) 7. 10% duty cycle: While the FPX3 is capable of transmitting continuously (the case temperature will rise noticeably) this will be in contravention of the sub-band restrictions. Units operating in the high power 869.4-869.65MHz sub-band are limited to 10% maximum transmit duty cycle. It is the responsibility of the user to ensure that this restriction is complied with. Alternatively, the user may wish to implement a listen-before-talk protocol (using the RSSI output). See EN300-220 for further details Radiometrix Ltd page 3 FPX3 Data Sheet Serial interface commands Serial data is sent to the unit on the programming input (PGM). To successfully program the unit, it must be powered Unlike earlier Radiometrix multichannel units, the FPX3 has separate N and R registers for each channel, on transmit and on receive. In other words, the frequency of each channel is individually programmed in every mode. Commands include: Commands GOCHAN a SETPAR SETSER <cr> / # Function serial select of channel a (ch0 to 7) channel selected by 3 bit parallel input channel selected by most recent 'gochan' operation process entry clear all buffers disable command mode Most users will not need to edit the table which relates channel frequency, channel number and synthesizer register programming values. The commands below are used to access the eeprom table containing this information. Users should be warned that, in order to get the optimum switching speed from the module, the standard channel setup uses a different reference frequency for each channel, and the absolute calculated channel frequency is allowed to deviate by up to +/-2KHz from the nominal LOADaa nnnnn (aa = 0 – 7) LOADaa rrrrr (aa = 8 – 15) LOADaa nnnnn (aa = 16 – 23) LOADaa rrrrr (aa = 24 – 31) load the N values for receive operation load the R values for receive operation load the N values for transmit operation load the R values for transmit operation Reference frequency (10MHz/R) must be in the range 210 to 300KHz (tx) or 175 to 300KHz (rx). As a rule of thumb, an R value greater than 45 (tx) or 55 (rx) should be viewed with suspicion. a = single digit channel number from 0 to 7 aa = eprom location number from 0 to 31 nnnnn = a synthesizer N register value, (up to 65535) rrrrr = the synthesizer R register value, (up to 16383) ALL COMMANDS MUST BE IN UPPER CASE. Notice that the synthesizer and VCO operate at half the output frequency, so for a frequency of 869.475MHz, the actual N/R values will be set for 434.7375MHz Further information TBA NOTE: A pause of at least 50ms must be allowed between command strings (EEPROM programming time) Radiometrix Ltd page 4 FPX3 Data Sheet Condensed specifications (All details are provisional) Frequency Frequency stability Channel spacing Number of channels Supply Receive Transmit: Operating temperature Spurious radiations 868 – 870MHz (EU) 865 - 867MHz (India) +/-5ppm (better than 5kHz) 100kHz (FPX3-86x-20) 50kHz (FPX3-86x-10) 8 maximum FPX3-869-20 for EU CH0: 869.475MHz, CH1-CH3: 869.565MHz CH4-CH7=869.50MHz for backward compatibility FPX3-869-10 for EU CH0:869.450MHz, CH1:869.500MHz, CH2:869.550MHz, CH3:869.600MHz, CH4-CH7=869.50MHz for backward compatibility FPX3-866-10 or FPX3-866-20 for India CH0 = 865.143 MHz CH1 = 865.294 MHz CH2 = 865.500 MHz CH3 = 865.789 MHz CH4 = 866.047 MHz CH5 = 866.383 MHz CH6 = 866.531 MHz CH7 = 866.829 MHz 5.0V regulated at 50mA 5.0V regulated at 500mA for 400mW output -20 to +70 οC (Storage -30 to +70 οC) Compliant with ETSI EN 300 220-2 and EN 301 489-3 (EU) Interface User RF and TX supply Recommended PCB hole size Size Transmitter Output power TX on switching time Modulation type TX modulation bandwidth Peak FM Deviation Adjacent channel TX power TX spurii Inputs Receiver Sensitivity image / spurious blocking adjacent channel Outputs 11 pin 0.1" pitch molex 5 pin 0.1" pitch molex 1.2mm (min.) 67 x 30 x 12mm 400mW (+26dBm) 5 ms FM, FSK (F1D, F3D) DC – 10kHz 16kHz nominal (FPX3-xxx-20) 8kHz nominal (FPX3-xxx-10) -37dBm <-36dBm 5V pk-pk CMOS data -117dBm for 12dB SINAD at 1KHz (FPX3-xxx-10) -115dBm for 12dB SINAD at 1KHz (FPX3-xxx-20) -107dBm for <0.1% data errors (20kbps NRZ) -55dB -80dB -60dB (Tested per.
