2. EXAMPLE CONNECTIONS:


Motor (H1)

Led (P2)

Servo (P5)

Lipo booster (L)

'P' outputs are either 3.3v or 0v (ground). Leds need resistors to limit current to no more than 20mA. High brightness leds allow a lower current which is preferred (eg: 2-5mA). Google will reveal how to select resistor values but 220-470ohms will be safe starting values.

The 'L' pad monitors the voltage of a battery when used with a voltage booster. This allows the receiver/motor to be powered with a boosted voltage and benefit from the convenience of a smaller battery, typically a single lipo. The receiver will cut power to the motor when the battery voltage falls to the LVC voltage.



3. BINDING

Bind once:
1. Switch Rx on and wait ~20s until led flickers fast.
2. Switch Tx on in bind mode.
3. Rx led should flash slowly; wait for it to go solid.
Change distance between Tx/Rx if binding does not work.




4. LED:
Led On = perfect reception (real-time indicator).
1 flash = Scanning (~2sec between flashes; no signal or not bound if never stops).
2 flash = Model currently not selected (Selecta).
5 flash = LVC/Brownout (voltage went too low; check battery/motor load).

5. PAPERCLIP CHANGES:
The following changes can be made by simply shorting two pads together (eg: with a paperclip):
1. Perform a 'Hard reset' (factory reset).
2. Change motor control between 'low off' and 'center off'.
3. Enable/disable LVC (eg: when using Nicads, NiHMs, LiFe cells).
4. Enable/disable Selecta.
5. Enable/disable Cruise Control/Failsafe.
'Paperclip' changes

6. PROGRAMMING:
This receiver has many other options that are described on the features page.
These are changed using a technique called 'programming': v611.
