Switching module RC-SM-4 Safety notes Please read this operating manual carefully and keep it for future use! The integrated circuits on the switching module are sensitive to electrostatic charge. Therefore it is important that you don’t touch these components, before discharging yourself (e.g.
If the total current consumption of all connected loads exceeds the current of 1 A, the black cable of the RC-SM-4 must be connected to the negative pole of the battery. If only a few normal LEDs are connected, this is not necessary.
"top" and "bottom" can be swapped! If a proportional control element is not used to control the RC-SM-4, but a 3-position switch, only areas A, N and D can be reached with this switch (without special programming in the radio).
2. Switch on the radio and supply the receiver with voltage. 3. Now plug the servo cable of the RC-SM-4 into a receiver slot. Within the next 5 seconds, the transmitter control element must move quickly 3 times to full scale in area A (ie “up”...
Switching module RC-SM-4 If the transmitter control element is not operated for 30 seconds or the voltage of the RC-SM-4 is disconnected, the last setting selected is saved and the RC-SM-2 then works in the set mode. This set mode remains until the setup is restarted and the mode is changed.
Switching module RC-SM-4 Mode 1: 4-way memory short / long If the control element (switch) is moved to area A or D, the corresponding output switches on and remains activated until this area is activated again. The output changes (toggles) its state each time it is activated.
Switching module RC-SM-4 Mode 2: 2-way memory short / 2-way momentary long If the control element moved short (less than 1 second) to area A or D in this mode, the corresponding output switches on and remains activated until this area is short activated again.
Switching module RC-SM-4 Mode 3: 4-way memory via areas A, B, C, D A proportional control element is required on the radio for this mode, since the intermediate areas B and C are also evaluated here. If the control element is brought into an area (A, B, C or D), the corresponding output switches on and remains on until this area is activated again.
Switching module RC-SM-4 Mode 4: 4-way momentary via the areas A, B, C, D A proportional control element is required on the radio for this mode, since the intermediate areas B and C are also evaluated here. If the control element is brought into an area, the corresponding output switches on and remains on as long as the control element is in this area.
Areas B, C and D are not evaluated in this mode. Since this mode only needs a "half" RC channel (area A), a second RC-SM-4 could be connected to the same channel using a Y cable, which is set to mode 6 and evaluates area D.
Areas A, B and C are not evaluated in this mode. Since this mode only needs a "half" RC channel (area D), a second RC-SM-4 could be connected to the same channel using a Y cable, which is set to mode 5 and evaluates area A.
The outputs of the RC-SM-4 can also be combined by simple parallel connection, e.g. to generate an impulse, no matter in which direction or in which area the movement takes place.
Mode 8: 4-way light switch single (step switch) In this mode the RC-SM-4 works like a kind of step switch with 5 steps (step 0 - step In the area A, the state of the light switch is increased by one step. In area D, the state of the light switch is reduced by one step.
Mode 9: 4-way light switch combined In this mode the RC-SM-4 works like a kind of light switch with 5 steps (state 0 - state In the area A, the state of the light switch is increased by one step. In area D, the state of the light switch is reduced by one step.
Switching module RC-SM-4 Mode 10: Indicator (steering), hazard warning lights, light 1+2 In this mode the RC-SM-4 is connected to the receiver's steering channel with a Y- cable parallel to the steering servo. When steering around a curve, the indicators are automatically activated.
Switching module RC-SM-4 Mode 11: Indicator (memory), hazard warning lights, light 1+2 Here the indicators are not controlled via the steering, but via a separate channel with a 3-position switch. If the indicators are switched on via the switch, they remain on until the switch is activated again.
Switching module RC-SM-4 Mode 12: Indicator (automatic shutdown), hazard warning lights, light 1+2 Here the indicators are not controlled via the steering, but via a separate channel with a 3-position switch. In contrast to mode 11, however, the indicators are automatically switched off again after an adjustable number of flashes.
Switching module RC-SM-4 Mode 13: Indicator (memory), light 1, light 2 Here the indicators are not controlled via the steering, but via a separate channel with a 3-position switch. If the indicators are switched on via the switch, they remain on until the switch is activated again.
Switching module RC-SM-4 Mode 14: Brake light, light, reversing light In this mode the RC-SM-4 is connected to the throttle channel of the receiver with a Y-cable parallel to the speed controller. When driving the model, the brake light and reversing light are automatically activated.

Short in area D: Increase speed by 1 step As a special feature, the RC-SM-4 always remembers its state (on or off), the last selected variant and the last set speed in this mode. These states are restored each time the supply voltage is applied via the servo connector. After it has been appropriately set and switched on, the RC-SM-4 can also be used as a “standalone”...
