Rx43d-2LS - Instructions (v511)

1. DEFAULT SETUP
- Reversable motor control with Limit Switches.
- 2x H outputs are enabled but can be changed (1H+8P or 2H+6P or 3H+4P or 4H+2P).
- 2x Limit Switches enabled but can be changed (all 'P' pads can be used with limit switches).
- All outputs can be customised / re-configured by the user.
- This receiver uses v511 software which does not have complex light options (eg: 'Indicators', 'Flasher').
2. LIMIT SWITCHES
- H outputs are 2-direction H-Bridges. The 2 'directions' are referred to as 'high' side and 'low' side.
- 'High' means the direction when the controlling channel is high. 'Low' is when the channel is low.
- P outputs can be configured as inputs for Limit Switches.
- One P controls one side of one H output.
- Any P can be used with any side of any H output.
- If the P is 'logic high', the side controlled is active (max voltage on P is 3.3v or current limited to 1mA).
- If the 'P' is low (0v) the side controlled is switched off.
- P3-P8 have internal pullups. P1-P2 require external pullups (eg: 10k to battery voltage).
- The limit switch should be 'open' (P floating or pulled high) to allow the H output to operate normally.
- The limit switch should be 'closed' (P pulled low to ground) to switch off one side of the H output.
| Output | Type | Channel | Other |
| H1: | Motor | Ch3 | |
| H2: | Motor | Ch2 | |
| F1: | 2-coil actuator / muscle wire / ADD1 | Ch4 | Left stick gives Switch action (eg: light) |
| F2: | 2-coil actuator / muscle wire / ADD1 | Ch4 | Right stick gives Switch action (eg: light) |
| P1: | Servo | Ch1 | |
| P2: | Servo | Ch4 | |
| P3: | Limit Switch for H2 Low side |
H2 Low side is active when P3 is floating (switch is open) H2 Low side disabled when P3 is 0v (switch is closed) |
|
| P4: | Limit Switch for H2 High side |
H2 High side is active when P4 is floating (switch is open) H2 High side disabled when P4 is 0v (switch is closed) |
|
| P5: | Servo | Ch5 | |
| P6: | Servo | Ch6 | |
| Arming/Activation: | Mid-stick to enable | Ch3 | |

Mid-stick to acknowledge |

| LED2 | External LED to show receiver activity | Disabled |

LIMIT SWITCH:
P1 - P2 need 10k resistor to pull high.
P3 - P8 do NOT need 10k resistor (they have internal pullups).
Use limit switch to pull P1 - P8 low to Ground to disable 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 WHEAT:
Grain of Wheat bulbs usually draw >8mA so are not suitable for use with P outputs (unless buffered with a transistor).
Grain of Wheat bulbs can be driven from F outputs. F outputs allow the intensity to be varied with stick movement or 'Travel Adjust'.
4. CHANGING OUTPUTS:
All outputs can be customised / re-configured:
PROGRAMMING
5. GENERAL:
The Rx is not insulated.
The PCB is thin so do not bend it.
6. LED:
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).
7. FAILSAFE:
Outputs are not driven (do nothing) on startup and while scanning.
Outputs 'hold' on short signal losses (<1sec) and then do nothing (>1s).
8. BINDING:
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.
