It is also available in the Indian licence free 865-867MHz band (General telemetry and RFID).

Radiometrix Ltd page 3 FPX3 Data Sheet Pin Description 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 pul lup to 4v (approx 50K) 4. This radio has no 'internal modem' functions in this version. 5. Programming port (P0) operates at 2400 baud. (Co mmand 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 sup ply (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 tra nsmitting 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).

Radiometrix Ltd page 4 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 Function GOCHAN a serial select of channel a (ch0 to 7) SETPAR channel selected by 3 bit parallel input SETSER channel selected by most recent 'gochan' operation <cr> 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) load the N values for receive operation LOADaa rrrrr (aa = 8 – 15) load the R values for receive operation LOADaa nnnnn (aa = 16 – 23) load the N values for transmit operation LOADaa rrrrr (aa = 24 – 31) 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: /square4 A pause of at least 50ms must be allowed between command strings (EEPROM programming time)
