Terminology

Ultrasonic ESC is the ESC block which switch FET at ultrasonic speed, make motor rotation extreme  smooth and quite. start voltage of ESC can also be adjusted for different type of motor.

 

Carefree reversing: Unlike some other control board, there is no need for TK series board to delay before being commanded to reverse, can go from full forward immediately to full reverse or vice versa
 

EPM ( ESC/PWM module) is peripheral which can be switched to ESC or PWM mode, allows the user to drive brushed motor or servo motor, in ESC mode, ESC port is enabled, can be used to drive brushed motor, In PWM mode, PWM port is enabled to driver servo motor, sound effect stopped when servo motor reach end point, TK20A has 2 EPMs for gun elevation(EPM1) and turret rotation/gun traverses(EPM2),

 

EPM No.

RealRecoil allows you to recreate real gun barrel recoil movement with single & cheap servo motor

 

Recoil Solenoid allows you to recreate MG/Auto cannon barrel recoil movement with Solenoid

 

V2  Mixer turning is achieved by reducing track speed and also increase opposite track speed to achieve smoother turning.

Installation Guide

Set Upper Hull Functions (CN9) Mode to match your tank hardware configuration (HL AirSoft, TAMIYA Recoil or MG recoil),

Disconnect RX-18 and plug cables to the same connector on TK board,

Set Sound Volume to middle

Install a switch cable (for example, HL Smoke Unit Switch Cable) to SW connector( Switch Cable Port)  as power switch.

 

Because HL tank already have power switch on battery cable path, so additional switch is not required, just to use a jumper to short pins in SW Cable port or connect a switch cable and keep it switched on.

 

When high current track motors are used, such as 400/480 motor, power switch on battery cable path will not be able to handle, connect a switch cable (for example, HL Smoke Unit Switch Cable) to this port as power switch.

Connect a recoil servo to J2(Optional),

Rewire Air-soft unit if you want to elevate and depress gun directly, see "HL Gun Elevation and AirSoft Correction" section

Connect channel cables to receiver according to RC mode( See picture "TK series connector and pin assignments" ) . if you are not sure what mode you RC system is, just swap CH2 and CH3 and try again.

 

TK20A board has BEC( Battery eliminate circuit), can power receiver through channel cables, no additional battery is needed for receiver

 

Set CH1, 2 and 3 trimmer on transmitter to center position, Set CH4 trimmer on transmitter to most left or right  position,

Connect power adaptor( See FAQ )

Switch on TK board and transmitter, you should hear turret traverse sound. if not, please contact us.

gently move CH4(Multi function control signal 2) trimmer to center till turret traverse is gone.

gently move CH2(Throttle ) trimmer up and down if you hear motor hum sound.

Cannon firing sound should be generated and recoil servo should moves when move CH3 stick to most top position, if not, gently move CH3(Multi function control signal 2 ) trimmer up and down till it work correctly.

You are all set

Disconnect power adaptor and connect battery( make sure that battery is fully charged).

 Tank Personalization( Patent Pending)

Settings of TK series board can be changed by a IR configuration remote as IR command transmitter, and TAMIYA battle unit(TBU),  Heng-Leog battle unit(HBU), or our IR configuration line as IR command receiver.

 

Steps to change settings:

STEP 1: Turn power off, Turn power off, Turn power off,

STEP 2: Plug programming line/TBU/HBU through TBU/HBU base into CN2 Infrared Port ,  

STEP 2: Install a jumper to J2 as shown below, Turn power on,

STEP 4:Refer to function table listed below, point IR configuration remote to TBU/HBU/Programming line receiver, and press the button of setting that you want to change,  "*" sign in function table means the default setting that is programmed in factory

STEP 5: Indicator on TBU/HBU flashes according to new setting value.

STEP 6: turn power off, remove jumper on J2, then turn power on and TK board runs with new settings.

FAQ

 

Q: My TK board can not  register a hit from Tamiya tank.

A: To check "Receive Tamiya IR code" setting. TK board  won't response Tamiay IR code when this setting is disabled.

 

Q: The airsoft motor does not run until after the gun fire sound has played and the reload sound has happened. I want the airsoft motor to run while the gun sound plays. I also planned to make recoil work with the airsoft…but when I fire the gun, the recoil servo operates in time to the sound…but has returned to the normal position when the airsoft motor operates.
A: Just need to set Main Gun Function Mode to AirSoft mode, then cannon sound, servo recoil and airsoft unit will be synchronized.

 

Q: I already set Main Gun Function Mode to HL AirSoft MODE, but AirSoft motor does not run when I give fire cannon command.

A:To correct airsoft unit wiring as HL Gun Elevation and AirSoft Correction section mentioned.

 

Q: Airsoft unit fires continuously and have no cannon sound.

A: When main Main Gun Function Mode is configured to AirSoft Mode, TK board start to drive AirSoft motor (thought CN9 3rd &4th pin) when fire cannon command is received. when Airsoft just fired, Airsoft switch is closed , TK board knows it thought  CN3  Pin4 & Pin5. and then stop to drive Airsoft Motor and start to generate cannon. So in order to make it works properly,  AirSoft motor need to be connected to CN9 pin3 and pin4. AirSoft switch connector to CN3  Pin4 & Pin5.

You can simply test it by a tweezers, to short and release it will stop AirSoft motor.

 

Q: How to avoid damage that caused by short circuit to the board?
A: Damage can be prevented by using a current limited power adaptor as power source, first to find a ~6V, 400mAh power adaptor, 1K 1/4W ohm resistor, LED and a motor cable(from HL cable Set)

then connect + wire(with white strip) from adaptor to red wire of HL cable, - wire to black wire of HL cable, adn wire resistor and LED as the following to act as indicator.

Each time, when you did some modification on circuit or after installation, use this as power source fist. plug connect each by each, and LED will be dimmed immediately if any shortage in circuitry and not thing on TK board will be damaged because power can only supply low & limited current.

 

The board might be act very strange when it's power by this, such as motor can not moves will, cannon fired unexpectedly when turret rotation sound comes up, these are quite normal because current is not enough.

 

Q: How to interface TK board to 6W external sound booster(amplifier)
A: This picture shows the pin assignment of external 6W amplifier, in this example, Battery + & Battery - are power input pin, SIN+ and - is for audio signal input,  SPK+ and - is speaker port

First to disconnect black wire from HL Volume control board and isolate it with tape, wire a 2-P, 2.54mm pitch connector wire to Volume control board as shown below

Then to power amplifier by battery

Finally, connect power form TK board to Battery+ & Battery - pin, connect 2-P, 2.54mm pitch connector wire SIG+ and SIG-,and then connect sparker to SPK+ and SPK- pin.

 

Here is pin assignment of another type 6W AMP, just refer to the above and wire pins with same pin assignment.

 

Generally, higher the input power, higher the sound output power on speaker, so we can also use a DC-to-DC voltage booster to convert battery voltage into higher voltage, then to drive external audio amplifier to have more solid and powerful sound,

 

Because output ripple is much lower after DC-to-DC conversion, so this can also reduce  motor "humm" sound during motor start up and at low speed. another benefit of this configuration is that you can use 8-ohm speaker but still have good loudness. In the example below, we use an adjustable DC-to-DC voltage booster to convert battery voltage into 12V.

 

Step 1: first to connect AMP to TK board and battery as describe previous and make sure it sounds correctly,

Step 2: connect DC-to-DC voltage booster to battery only, measure the output voltage, if voltage is higher or less than 12V, adjust VR on it till output voltage is around 12V,
Step 3: disconnect AMP from battery power then connect to the output of
DC-to-DC voltage booster.

 

HINT: use VR pointed by black arrow in this diagram to adjust voltage to 12V before powering amplifier

Wiring diagram for 15W amplifier: Use VR on DC/DC converter to set output voltage to 15V

Q: When I move left stick backward, only the right track goes backward the left track does not move, It is possible I crossed the +positive and --negative terminals when connecting the new motors?
A: Yes, whe

We recommend that to use power adapter(7.2V, 400mAh) as power source after rewiring. then switch to battery when everything are tested OK.

 

Q: Tank hull recoil movement direction is not correct, moves forward and then backward while firing main gun.
A: Just need to swap motor cables, CN6 to Motor Right, CN7 to Motor Left, and turn on servo reverser function on throttle channel from radio transmitter.

 

Q: All function runs but just no sound!!

A: This can be the common issue on HL Volume Control board, just to short outer pins of CN4 with tweezers to verify it. if  sound comes out when doing this, the HL volume control board is broken.

Q: Do I need noise filtering capacitor on motor

A: Yes, it's needed to prevent back EMF to interference TK20 board. All HL stock tank already have it on motors

This type of capacitor is not good, DO NOT USE!

 

Q: What's the IR battle range of TK20

Q:Tank moves backward faster than forwards and does not turn. It only turn if firstly turn steering stick and secondly throttle stick.

A: To turn off mixer on transmitter and test again.

 

Q: Can get motor sounds, cannon sounds, turret sounds, but no motion on either drive motors or turret rotation gearbox

A:  Check if battery voltage is too low, auto cutoff function cuts motor off when battery voltage is too low.

 

Q: What is Mixer

A: A piece of software that converts Rudder and Throttle control signal to Left and Right track speed signal. All TK board has mixer on it, mixer function on RC transmitter need to be turned off.

 

Q: What is Safety shutoff:

A: Controller cuts motor off and waits signal come back.

 

Q: What is Auto cutoff:

A: The motor cutoff will occurred when battery input drops below minimum supply voltage of controller.

 

Q: Which RC system can works with TK board:

A: Basically, TK can work with all kind of aftermarket RC system as long as it's PWM system, here is a table list most popular one.

Q: Audio Amp thermal protection:

A: that turns off device when junction temperature over 150 degree C to prevent damage

 

Q: Is it possible to make additional settings using existing IR signals for example to make HL IR signal and 9 hits can take, originally 5 hits?  

A: yes,  IR code to receive, IR code to transmit, preset & battle data can be set independently.

 

Q: Is it possible to set setting with other device (not SONY IR code remote)?

A: Only Sony IR code remote can be used, you can also have universal remote and configure it to SONY mode.

 

Q: Any Other SONY remote, such as SONY Bravia unified IR Configuration Remote, can config TK20?
A: Can't sure, with more and more setting function are added, some code not common on every remote are used. so we suggest to use same remote as we use.

 

Q: What's BEC

A: BEC stands for battery elimination circuit. This circuit powers the receiver thought channel cable, no secondary battery source is required.

 

 Precaution

 Use dry battery or power supply as power source at testing to keep burn down anything if any error on modification. then use chargeable battery when every function working normally.

Read carefully and fully understand the instructions before commencing assembly.
