DT Receiver - Rx41d-v502 - Instructions
1. DEFAULT SETUP
- Train with 1 Motor (reversable) and 1-3 relevant Lights.
- Car with 1 Motor (reversable), Steering (2-actuator or 2-muscle wire) and 3-6 Lights.
- Plane requires changes.
- This receiver has full stick Ch1 throttle control enabled ('low' stick is off and has separate 'direction' channel) (video).
- This is useful for trains in particular (greater 'stroke' for throttle control and no need to 'find' mid-stick for 'center off' systems).
- The Direction channel defaults to Ch3 to allow 4ch transmitters but is easier to use if changed to a switch (eg: Ch5).
- All outputs can be customised / re-configured.
|H1:||Motor 'full stick' control (low off)||Ch1||
Ch3 forward/reverse 'direction' change
(only considered and toggled when Ch1 is low)
|F1:||2-coil actuator / muscle wire / ADD1||Ch2 steering||Left stick gives Switch action (eg: light)|
|F2:||2-coil actuator / muscle wire / ADD1||Ch2 steering||Right stick gives Switch action (eg: light)|
|P1:||Driving lights Leds (Front & Rear)||Ch3 forward >2s toggle on/off|
|P2:||Left indicator Led||Ch4 left <1s on||Ch2 steering/auto cancel|
|P3:||Right indicator Led||Ch4 right <1s on||Ch2 steering/auto cancel|
|(P2/P3):||Hazards (Left+Right)||Ch4 left >2s toggle on/off|
|Arming/Activation:||Low-stick to enable||Ch1|
Low-stick to acknowledge
|LED2||External LED to show receiver activity||P1 (driving lights)|
2. EXAMPLE CONNECTIONS:
for extra H output
LEDs with 1S Lipo:
Led's driven from P outputs only require a current limiting resistor (8mA max).
Led's driven from F outputs only require a current limiting resistor (2A max).
LEDs with 5-6v:
'P' outputs are 3v when 'off' and 0v when 'on'. So when used with higher voltages, the leds driven from P outputs also need diodes to reduce the voltage. This is because 5 or 6v is high enough above the 3v output to make Leds conduct even when P outputs are 'off'. An example is shown in the Led (P1) diagram.
Led's driven from F outputs only require a current limiting resistor when operated off any voltage up to 6v.
GRAIN of RICE/WHEAT:
These bulbs usually draw >8mA so are not suitable for use with P outputs (unless buffered with a transistor).
These bulbs can be driven from F outputs. F outputs allow the intensity to be varied with stick movement or 'Travel Adjust'.
3. CHANGING OUTPUTS:
The Rx is not insulated.
The PCB is thin so do not bend it.
Led On = perfect reception (real-time indicator).
1 flash = Scanning (~2sec between flashes; wrong model if never stops).
2 flash = Brownout (receiver voltage went too low; check battery/servo load).
Outputs are not driven (do nothing) on startup and while scanning.
Outputs 'hold' on short signal losses (<1sec) and then do nothing (>1s).
1. Switch Rx on and wait ~20s until led flickers fast.
2. Switch Tx on in bind mode and Rx led should flash slowly and then go solid.
3. Change distance between Tx/Rx if binding does not work.
