 Assembly Guide

Inspect metal portion on FETs and make sure they are not touched to each other after shipment

Set Main Gun Function Mode to match your tank hardware configuration (HL AirSoft, HL Recoil or TAMIYA 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.

 

When use F-4 Radio, connect receiver CH1~CH4 to TK20 CH1~CH4, Set transmitter control mode to mode 1, all reverser to REV position

 

 

TK20 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).

 

 

 HL Gun Elevation and AirSoft Correction

In HL original design, gun Elevation and AirSoft sharing same driving H/W, so the gun elevation can only be controlled  in one direction, if you missed the angle you want, you will need to wait a full cycle of gun elevation, to correct this problem, we add dedicate AirSoft control h/w to TK20 board. the following shows you how to correct HL tank and get two direction elevation.

 

The picture below is original wiring in HL tank:

Modify it as the following:

1. Disconnect red wire between safety switch and gun barrel elevation unit.

2. Change original 3P connector to 4P type, add additional wire from safety switch to 4P connector,

3. Add 4P connector HUL-8P PCB connector

4. AirSoft unit is now controlled by red-black pair, gun barrel unit is controlled by red-white pair. and you can connect 8P connector to CN9 on TK-18/20 with original cable.

5(Optinal). refer to wiring diagram, wire 2.2 ohm 1/2W (color code: red read gold gold) resistor to turret rotate, elevation and airsoft motor in serial to limit the current to protect FETs on TK22 in case you stall motor. you can find 2.2 ohm resistor on RX-18. Done!

 

 

 HL Tail Light Correction

Tail Light in HL tank is wire to MG light, so the Tail Light flashes when MG firing, this is very funny to us, to correct this problem and make tail light to be controlled with Headlight, please refer to the picture below and rewire it.

1. Remove 2 pin plug from PCB, twist angled pins to opposite side,

2. Connect Tail Light LED + pin(  Red wire of Tail Light cable) to CN9.3 pin( Yellow wire )

3. Connect a 200 Ohm resistor between 2-P connector pin and CN9.2 pin(Green), a SMD type resistor is used in this example to save space.

Gun Barrel Stabilizer(GBS) overview and installation

GSU is an optional module of TK22. When GSU is turned on, it detects the tank movement and compensate gun rotation and elevation to stabilize the gun automatically. When GBS is turned on, operator can still change gun elevation and direction under GBS compensation, GSU have the following features:

 

- 2-axis gun stabilization in turret rotation and gun elevation.

- Fully programmable gun elevation real angle calculator allows GBS to work with different elevation setup,

- Fully programmable turret motor controller allows GBS to work with different motor/gear box setup,

- Engine deck detection, gun raise automatically when gun travels above engine deck,

- Auto reload position, Gun barrel goes to to reload position after fire, and return to last position when reload when reload time expired,

- Adjustable Engine deck level,

- Adjustable auto reload position,

-  GBS unit dimensions: 20 x 16 x 3mm.

- Unified platform design, allows all existing TK20/TK22 can be shipped back to us to upgrade to TK22G2

Power on GBS calibration - When power on TK22G2, GSU starts a reset process and must be kept stationary.

The GBS LED blinks during GBS calibration and you must not to  move the tank during calibration. The GBS are very sensitive and you should not touch or vibrate the GSU during power on reset. The process will take a few seconds. The HEADLIGHT led will turn on when calibration completed.

An in-series 200-ohm resistor is needed for GBS LED

  

Mounting of GBS - The GBS unit must be mounted securely and horizontally on the turret, here is an example, first to use Tamiya 5mm square beam, cut into 5~6mm in length, make 1.6mm hole, then glue to turret floor by cement

Bolt GBS unit with the screws came with GBS unit, and plug connector to J6 port on TK22G2

For accurate motion detection, it must be kept within 5 degree with turret base plate. mounting directions is as shown in following picture. Servo for elevation is Futaba S3003 in this setup.

 

Turning GBS on/off - GBS can be turned on/off by move right stick to top, move left stick to right, you can also hear click sound when turn it on and off

Adjusting gun elevation angle - The gun elevation V gain setting is used to adjust the amount of gun elevation servo angle to meet different mechanical setup. adjusting procedures are

 

-First to put TK22G board in IR programming mode.

-Turn GBS on and moves the gun barrel to horizontal position.

-Tilt the tank for 15-20 degree.

-Use IR configure remote to adjust servo gain value until the gun is horizontal again.

-Power off TK22G board, remove jumper and turn power again to leave IR programming mode.

 

Adjusting gun elevation angle calculator gains - The angle calculator's fast gain and slow gain settings are used to adjust the angle calculation, adjusting procedures are

 

-First to put TK22G board in IR programming mode.

-Turn GSU on and moves the gun barrel to horizontal position.

-Tilt the tank for 10-20 degree.

-Rotate turret in various speed ( from low to full speed), if elevation speed is too slow, increase slow gain a bit, otherwise, reduce slow gain,

-rotate turret to 12 o'clock position, tilt the tank hull about 15-20 degree in various speed, if elevation speed is too slow, can not keep up tank hull tilt speed, increase fast gain a bit, if elevation moves faster the hull tile speed and over the position it should be (overshoot), decrease fast gain a bit

-Power off TK22G board, remove jumper and turn power again to leave IR programming mode.

 

Adjusting turret rotation motor control gains - The turret rotation motor P , I  and D gain are used to meet the characteristic of turret rotate motor and design on your tank. adjusting procedures are as the following.

 

-First to put TK22G board in IR programming mode.

-Turn GSU on

-Rotate tank hull from stationary to low speed, if turret motor does start well when tank rotation start, increase start gain a bit, if turret motor runs too fast (overshoot) , decrease start gain a bit.

-Rotate tank hull in various speed( low, middle and full) , if turret rotation speed is too slow, can't keep up hull rotation, increase speed gain, otherwise, reduce speed gain,

-Stop tank hull rotation from various speed, if turret stops too early, decrease stop gain, if turret stops too late increase stop  gain.

 FAQs

Q: Can I use GSU on TK22 or TK22.

A: No, GSU can only work with TK22G1 or TK22G2.  existing TK22 board can be returned to upgrade to TK22G1/G2 with upgrade fee.

 

Q: My Tk22 can not  register a hit from Tamiya tank.

A: To check "Receive Tamiya IR code" setting. TK22 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, TK22/20 start to drive AirSoft motor (thought CN9 3rd &4th pin) when fire cannon command is received. when Airsoft just fired, Airsoft switch is closed , Tk22 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: I accidentally shorted speaker wire and now had barely any sound, everything still works but hardly any sound.
A: A FB( pointed by red arrow) might be damaged because of over current, please remove it and short its two pads by solder or wire. Of course, It's the best if you can find a 200 ohm FB and replace the broken one.

 

2nd, the audio amplifier ( pointed by green arrow) goes very hot when operating, do not apply glue or double faced adhesive tape on it and left some space for it for heat dissipation.  

 

Q: How to interface TK22 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 or additional 11.4~12V battery pack, normally, higher the power voltage, higher the max. output power to speaker, just make sure ground of TK board & additional battery pack are connected firmly. In this case, we just get power from TK22 bottom side.

Finally, connect power form TK22 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 2nd type 6W AMP, just refer to the above and wire pins with same pin assignment.

 

 

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, when +positive and --negative terminals are crossed, one of terminal will burn out immediately, you can bend FETs a little bit to check these traces, one of them should be broken. you can reconnect it by soldering to fix the problem.

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: It is possible to change the sound?

A: No, to change sound on TK board required some equipment and technique, so you can not do it by yourself, but we can if you send us processed sound file(22KHz, 8-Bit format) that you want to program into, average lead time is 2 weeks, This service is free of charge with MOQ( Minimum order quantity) of 3 units. The following are the sound effect section you can change.

 

- Cannon

- Machine Gun

- Gun elevation

- Turret travels( 4 sections, start, loop1, loop2 & stop)

- Engine Start, engine step 1~8, engine stop.

 

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 TV 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.

Metal part on FET can not be touched with any metal when TK board is operating.
