Download DSS1 - RC car lights switch system

ing lights are switched off and brake lights are switch on until the speed controller stick in not returned
to neutral position. If one-way controller with mechanical brake mode is chosen, so when stick is
moved from forward to backward position (i.e. mechanical brake brakes) reversing lights are permanently switched off and brake lights are switch on, until the speed controller stick is returned to neutral
position.
*** This setting is relevant only if the selected type of controller 1 or 2 (two-way controllers with brake).
Set time not to be longer than the passive stopping time of model from full speed. If the speed controller stick is in neutral for more than a specified time, the switch supposes that model is already standing, turn off brake lights and when the speed controller stick is moved to the back position again brake
lights are switched off and reversing lights are switched on (if model goes backward).

DSS1 - RC car lights switch system
Description:
RC cars lights switch system DSS1 is designed to control five lighting circuits (left and right blinkers,
reversing lights, brake lights and headlights) in RC car model. Switch is connected to the receiver parallel with steering servo and speed controller (controller in model may be two-way without brakes or
with brake/reverse for one or both directions or one-way with mechanical brake). These two signals
are used for switching of all five outputs. Turning of the blinkers is derived from steering servo deflection. Reversing lights are turned on, when model is moving backwards. The brake lights are activated,
if the model slows down (in the forward or backward direction). Headlights (siren, beacon) or all blinkers can be turned on (if model stands only) by short steering servo deviation from the neutral to the
left or to the right and back. Output for headlights connecting can also be switched into the mode of
sound generation of police siren, fire siren or flashing beacon. In the case RC signal for speed controller is lost switch turns on head, reversing and brake lights. If signal for steering servo is lost, all blinkers begin to flash. Current at each output can be set in range of 20 - 80 mA according to the number
of connected LEDs. Output current is stabilized, so the LEDs can be connected directly to the switch
without a serial resistor. The switch has a built-in connector for the speed controller and steering servo
connecting.
Notes, advices, experiences:
Connect at the outputs loads with adequate power only. When installing the switch into the model to
make sure that it is not heat insulated. LEDs can be connected in series or parallel. If receiver supply
voltage is not enough for the LED diodes, external power supply can be used. In this case supply voltage should not be more than 4 Volts higher than voltage of connected load to avoid switch overheating. Negative pole of external source must be connected to receiver’s supply minus. The positive pole
of the load is connected to positive pole of external source, negative pole of load is connected to the
pins on the switch label side. The transistors in the switch connect negative pole of load to minus. If
load is inductive (speaker, transducer, relay coil, small engine, etc.), it must be bridged by diode (e.g.
1N4148), cathode to plus. When as a speaker is used piezo siren, it is useful to connect it in parallel
with a capacitor of about 500 nF which filters out unwanted higher frequencies. If you want to connect
parallel LEDs with different voltage, current distribution must be ensured by serial resistors. Power
supply voltage of switch (receiver) must not be greater than 6 Volts, otherwise there is danger of
switch damaging. If supply voltage is below 4 Volts, blinkers will not blink. Input pulse amplitude must
be at least 60 % of supply voltage, otherwise the switch cannot detect them!

Connecting to the receiver, programming button and LEDs on the outputs:
Inputs: connect servo cable (GND, +5 V IN1/OUT1) to receiver to signal for steering servo and servo
cable (GND, +5 V IN2/OUT2) to signal for speed controller. Steering servo can be connected to three
pins (GND, +5 V IN1/OUT1) and speed controller to three pins (GND, +5 V IN2/OUT2). Minuses
(GND) of all servo cables are always toward to the edge of board.
Programming button: to set one of the four outputs (flashers - BLINKRY, head lights/sirens/beacon SVETLA, reversing lights - COUVANI and brake lights BRZDY) always connect button to the two
holes of programming female connector.
Outputs: connect LEDs to the pins marked Left blinker - BLINKRY VLEVO, Lights/beacon SVETLA/MAJACEK, Reversing lights – COUVACI SVETLA, Brake lights – BRZDOVA SVETLA and
Right blinker – BLINKRY VPRAVO. For each output there are two pairs of parallel pins. The pins on
the label side are negative (for LED cathode) and pins on the other side are positive (for LED anode).
Switch system setting:
Switch processor memory can store all parameters that are necessary to synchronize model activity
and lights switching. Type and number of adjusted parameters depend on what output is set.
If you want to adjust parameters, connect the switch to the receiver, connect output LEDs and programming button on the set input. Setting mode can be entered by connecting the power supply while
programming button connected to one of four inputs and it is pressed. When you release the button,
chosen output of the switch is in setting mode. Remaining outputs are disabled. Adjustment is done
with short (up to 2 seconds) press the button, saving to the memory is done with long (over 2 seconds) pressing the button. Short button pressing is indicated by shorter, long button pressing by
longer switching of all outputs. If it could damage connected loads, unplug them and plug such as a
LED. Parameters are adjusted step by step. Adjustment is necessary (and it is possible at any step) to
finish by power supply disconnecting. If the switch is in setting mode, follow these steps:
Headlights - Police Siren - Fire Siren - Beacon output:
1) Output current setting*: press button zero to three times short, set output current of 20 mA (0x)
40 mA (1x), 60 mA (2x) or 80 mA (3x). Then press and hold the button long, the choice is saved and
setting is moved to the next parameter.
2) Output mode setting: press button zero to three times short, you set mode head light (0x), police
siren (1x), fire siren (2x) or beacon (3x). Then press and hold the button long, the choice is saved and
setting is moved to the next parameter.
3) Limit length of steering servo signal for front lights (sirens or beacon) switching setting: set
the steering stick on the transmitter to such position in which you want head lights (sirens, beacon) to
be switched. Then press and hold button long, actual pulses will be saved. If the beacon is selected,
setting is moved to the next parameter. If selected function is not beacon, setting is finished.
4) Time of beacon shine increasing setting***: press the button short as many times as long beacon shine must be increased (minimum is 0 pressing, i.e. time is zero, maximum is 50 pressings, i.e.

setting is moved to the next parameter.
2) Grade of deceleration that evokes brake lights shining setting*: press the button short as many
times as sensitivity you want to set. The greatest sensitivity, i.e. it responses to a small deceleration is
for zero time button pressing, the lowest sensitivity, i.e. a reaction to a larger deceleration only is at
10 times button pressing. Then press and hold the button long, the choice is saved and setting is
moved to the next parameter.
3) Time of brake lights after-shine setting: press the button short as many times as long brake
lights must be turned on after last deceleration is detected (minimum is 0 pressing, i.e. time is zero,
maximum is 50 pressings, i.e. the time will be 50 x 0.1 s = 5 s). Then press and hold button long, the
choice is saved and setting is moved to the next parameter.
4) Brake lights in neutral position behavior setting: press the button zero time short if you don’t
want brake lights will always shine when signal is in neutral position (but brake lights after-shine is unchanged) only or press button short one time if you want brake lights will always shine when signal is
in neutral position. Then press and hold button long, the choice is saved and setting is finished.
5) Finally, disconnect the power switch and after the connection you can start using it.
* Current setting only affects the choice of head lights or beacon, sirens are not affected.
** Head lights (sirens or beacon) can be switched on and off only if the speed stick is in neutral position (standing model) and the steering stick is moved from neutral position over limit position and back
to neutral one.
*** Beacon intensity dividing into four phases brings more realistic blinking like real beacon lamp.
* Try optimal setting to avoid accidental switching of brake lights when there is too great sensitivity.
** Set time of brake lights after-shine not to be longer than the stopping time of model from full speed.
After-shine is interrupted when model is accelerating again.

on (minimum is 0 pressing, i.e. time is zero, maximum is 50 pressings, i.e. the time of this section will
be 50 x 0.1 s = 5 s). Then press and hold button long, the choice is saved and setting is moved to the
next parameter.

off (minimum is 0 pressing, i.e. time is zero (lights will be shine permanently), maximum is 50 pressings, i.e. the time of this section will be 50 x 0.1 s = 5 s). Then press and hold button long, the choice
is saved and setting of blinkers is finished ***.
9) Finally, disconnect supply power and after its reconnection you can start using the switch.
* All blinkers can be switched on only if the speed stick is in neutral position (standing model) and the
steering stick is moved from neutral position over limit position (it must be different to head lights
switching position) and back to neutral one. If steering signal is lost, all blinkers are activated too.
** The pulses must be in according to conditions that HIB1 > HIB2 > HIB4 > HIB3 or HIB1 < HIB2 <
HIB4 < HIB3. If these conditions are not respected, switch will not work correctly.
*** If set time zero, the blinker output is switched on permanently. Time of blinkers off plus time of
blinkers on is blinking period.

controller without brake (0x), with brake in the forward direction (1x), with brake in both directions (2x)
or one-way controller (3x, usually model with combustion engine and with a mechanical brake). Then
press and hold button long, actual pulses will be saved and setting is moved to the next parameter.
3) Limit length of speed controller signal (HIC1) when model starts to go forward*: set the
speed controlling stick on the transmitter to such position in which model starts to go forward. Then

speed*: set the speed controlling stick on the transmitter to such position in which model goes backward with maximal speed (or there is maximal brake). Then press and hold button long, actual pulses
will be saved and setting is moved to the next parameter.
7) Estimated time of model stopping setting***: press the button short as many times as long
brake lights must be turned on after speed controller stick is returned to neutral position (minimum is 0
pressing, i.e. time is 0.5 s, maximum is 9 pressings, i.e. the time will be 1+ 9 x 0.5 s = 5 s). Then
press and hold button long, the choice is saved and setting is finished.
8) Finally, disconnect the power switch and after the connection you can start using it.
* These limit pulses must be already set whenever they are used for calculations of other outputs
switching too. The pulses must be in according to conditions that HIC2> HIC1> HIC3> HIC4 or HIC2
<HIC1 <HIC3 <HIC4. If these conditions are not respected, switch will not work correctly.
** If two-way controller mode without brake is chosen, reversing lights are on when the speed controller stick is in back position. If two-way controller with brake in one direction mode is chosen, so when
stick is moved from forward to backward position (i.e. model doesn’t reverse, but brakes) reversing
lights are switched off and brake lights are switch on, until the speed controller stick in not returned to
neutral position. If two-way controller with brake in both directions mode is chosen, so when stick is
moved from forward to backward position or vice versa (i.e. model doesn’t reverse, but brake) revers-
