This is the FrSKY (far sky) Futaba FASST compatible TFR4 8Channel PPM SUM full range receiver - this is ideal for PARIS AIR -> Futaba pilots where access to all 4 x Aux Channels is required - 8 Ch single wire . So normally PARIS AIR can only receive Aux 1 and aux 2 with a multi-cable Rx - However with this TFR4 Full Range Futbaba FASST compatible Rx the PARIS will receive Aux 1, Aux 2, Aux 3 and Aux 4. Can also be used with NAZA and Wookong M now under new firmware released recently (Sep 2012)
This is the code change in Arduino needed to use the PPM SUM output
Compatibility FASST 2.4G Air Systems (7CH Mode/Multi Mode): 14SG - or 6EX, 7C, TM-7, TM-8, T8FG, T10C, TM-10, T10CG, T12Z, T12FG, TM-14, T14MZ, etc. does not work with 8J FASST 2.4G Surface Systems (C1 Mode): 3PK, 4PK, etc.
Number of Channels: 4 Operating Voltage Range: 3.5V~10V
Operating Temperature Range: -10℃~80℃
Weight: 6.2g / 4g (naked)
1) Compatible with FASST 2.4G: Air Systems (7CH Mode/Multi Mode) & Surface Systems (C1 Mode); 2) CPPM and RSSI (PWM) output - If CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8, and CH2 will output RSSI (PWM); 3) Lighter weight and physically smaller; 4) Two selectable failsafe setting options.
in case you are not sure - TFR4 excludes futaba Sbus - CPPM is not the same as Sbus - both use 1 wire but are totally different types of signal- for PARIS AIR Hero•32 Naze Sbus with Futaba - use TFR3SB here
Turn on the transmitter, connect the battery to the receiver while pressing receiver’s F/S button. After the RED LED is off and GREEN LED is solid, the binding process is completed and the receiver is operating normally.
TFR4 support two selectable failsafe setting options, either use native failsafe position preset on the transmitter side, or set failsafe on TFR4.
Use native failsafe position preset on the transmitter side
If not disabling failsafe on the transmitter side, TFR4 will use native failsafe position preset on the transmitter side.
Set failsafe on TFR4 side
TFR4 supports failsafe function for all channels. Follow the steps below to set failsafe on TFR4: 1) Bind the receiver first, and disable failsafe on the transmitter side; 2) Set all transmitter controls to the desired failsafe position; 3) Press briefly the F/S button of the receiver, the GREEN LED of the receiver will flash twice, indicating the failsafe is set up successfully. If you do not need the failsafe function any more, just re-bind the receiver to set default failsafe mode.
Hint: If not disabling failsafe on the transmitter side, TFR4 will use native failsafe position preset on the transmitter side.
Waiting to be bound
3. How to get CPPM and RSSI from TFR4
If CH3 and CH4 are connected by a jumper, CH1 will output CPPM SUM for CH1~CH8, and CH2 will output RSSI (PWM).
Note: CPPM channel can not handle all eight channels at the same time with all throws are maxed out from 800-2200usec , as it does not have enough frame gap. It is recommended to set Ch limits as per normal for PARIS to 1095->1905 including Aux Ch 5,6,7,8 - then all is good
