'H' outputs are intended for brushed motors. This receiver has two H outputs but must be connected in parallel and used as one (H1). One is on the main receiver and the other is on the daughter board. Together it has a 6A rating. This is a maximum 'worst case' value usually measured by connecting a fully charged battery direct to a stalled motor.

'P' outputs are either 3.5v 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.

'F' outputs are buffered with a fet. They are 0v (ground) when on and floating (disconnected) when off. Up to 2A is possible but lower currents are much better. Current-limiting resistors are required for leds. The load is normally connected to positive and the F output provides a path to ground to switch it on. F outputs are marked with letters on the receiver (A, B, C and D). The are programmed as P outputs (P13, P14, P15 and P5). eg: F1 = A = P13.

The 'L' pad monitors a single cell lipo when used with a voltage booster. This allows the motor to be powered with a boosted voltage and benefit from the convenience of a single lipo. The receiver will cut power to the motor when the voltage falls to 3v (LVC). The L pad is not intended for use when powering a receiver direct from a single lipo.



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).
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.
