Rx45-22 Instructions (v511)


PRODUCT: Rx45
PROGRAMMING: v511


Outputs

Tx21

Tx22

1. DEFAULT SETUP

- Train with center off motor control intended for Tx21/Tx22.

- The 'direction' switch can control 4 lights or on/off functions and a servo.
- The 'bind' button can operate 2 lights and a servo.
- For the Rx to work the Selecta switch has to be in the position learned during binding.

- All settings can be customised / re-configured.

Output Type Channel Other
H1: Motor 'center off' control Ch1 'speed' knob 130Hz PWM frequency
0.5A max stall current

F1: On/Off light or buzzer Ch3 'direction' switch Tx21: Right=On
Tx22: Up=On
Led needs current limiting resistor

F2: On/Off light or buzzer Ch3 'direction' switch Tx21: Left=On
Tx22: Down=On
Led needs current limiting resistor

P1: On/Off light (front) Ch3 'direction' switch Tx21: Right=On
Tx22: Up=On
P1 is also set up as 'LED2'
Led needs current limiting resistor

P2: On/Off light (rear) Ch3 'direction' switch Tx21: Left=On
Tx22: Down=On
Led needs current limiting resistor

P3: Servo

Ch3 'direction' switch
P4: Servo Ch5 'bind' button

P5: On/Off light Ch5 'bind' button

Long press to toggle on/off (>2s)
Led needs current limiting resistor

P6: On/Off light Ch5 'bind' button

Short press to toggle on/off (<1s)
Led needs current limiting resistor

Selecta

Enabled

Ch2 Up to 12 locos can be associated with Selecta switch on Tx22
Outputs 'hold' their settings when deselected

Arming/Activation: Mid-stick to enable Ch1
LVC Mid-stick to acknowledge
Ch1 'LED2' 2-flash if triggered
LED2 External LED P1 Shows useful receiver activity


2. EXAMPLE CONNECTIONS:


2-way Motor (H1)

'Single' Actuator (H1)

F1 + F2 + ADD1
for extra H output

1-way Motor (F1)

Led (F2)

Led (P4)

Servo (P4)

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 (P4) 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'.



3. CHANGING OUTPUTS:

All outputs can be customised / re-configured:

PROGRAMMING




4. GENERAL:
The Rx is not insulated.
The PCB is thin so do not bend it.

5. 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).

6. FAILSAFE:
Outputs are not driven (do nothing) on startup and while scanning.
Outputs 'hold' on short signal losses (<1sec) and then do nothing (>1s).



7. 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.
