PREPARING THE #TX-3v2
THESE INSTRUCTIONS REFER TO THE RCS TX-3v2 2.4 GHz 5 CHANNEL R/C.
LAYOUT OF THE TX-3 TRANSMITTER HAND PIECE.
The small valve gear knob is in the upper middle. The larger steam regulator knob sits just below.
Top left is the ON – OFF switch with LED. Top right is the Bind/Ch # 5 pushbutton. Use for servo whistle.
1. “BINDING”.
The 1st procedure is to “BIND” the receiver (RX) to the Transmitter (TX).
“BINDING” is accomplished by following a few simple steps below.
When binding we recommend removing the servos from the RX in case they are not correctly adjusted. Adjust servo
parameters after binding has taken place..
HOW TO “BIND” USING A DSM2 RX OR RCS #ALPHA-3 ESC.
MANUAL BINDING using a binding plug.
1.1 Insert the “BINDING” plug supplied with the DSM2 RX into the “BINDING” pins on the RX.
You can also use the # BINDER switch assembly if you do not wish to get inside the loco.
1.2. The RX LED will start blinking very rapidly to indicate it is ready to be bound.
AUTOMATIC BINDING = no binding plug.
1.3 Turn the Auto Bind RX ON and the RX LED will blink slowly looking for a TX. Wait 20 seconds for the RX to enter
bind mode. The RX LED (& slave front headlight if programmed to) will blink rapidly and is ready to be bound.
FUNCTIONS OF TX-3
BUTTONS TO HOLD DURING BINDING
CH # 5 SERVO FUNCTION OF TX-3
1.4 Press and hold the right pushbutton on the handpiece marked with a hexagonal symbol. You may need to keep
TX & RX about 1 x metre apart for binding to take place.
1.5 Then press and hold the ON – OFF button to ON. Hold both buttons until the RX LED stops flickering & starts
blinking slowly. Then let both TX buttons go. The TX button also blinks slowly & then goes to solid ON.
1.6 The LED on all RX’s will blink more slowly & then go solid ON when “BINDING” is complete.
N.B. “BINDING” plug MUST be removed BEFORE the SYSTEM is turned OFF. (AB RX’s have no binding plug)
1.7 The “BINDING” plug is removed & stored safely.
RCS offers an optional extra # BINDER cable and switch. When fitted this will enable any non RCS loco to be bound to
any TX without requiring access to the inside of the loco. This will enable any loco to be swapped between any other
DSM2 TX’s. You will be able to “hand off” speed matched locos for MU’ing into a consist. (Uneeded with #BASIC-3)

2. PREPARING FOR USE WITH LIVE STEAM LOCOS.
Make sure the RX is OFF. Then re-insert the servos into the correct RX sockets.
The regulator servo goes in Ch # 1 (Throttle) socket.
The valve gear servo goes in Ch # 3 (Elevator) socket.
N.B. There is no battery/bind terminal on the DSM2-EM(AB) Auto Bind Rx.
Be careful selecting the correct terminal. They are marked on the back of the RX.
HOW TO ADJUST SERVOS USING REGULAR DSM2 RX’s. (See the instructions with our AB Rx’s for how to do it).
When using for the first time make sure both knobs are centered.
VALVE GEAR SERVO 
1.1 Then turn on the Live Steam loco RX. The two servos should immediately snap to the neutral position.
1.2 Adjust the valve gear servo connecting rod to ensure the centre position of the valve gear matches the servo.
1.3 Turn the small knob slowly to the right Clockwise (CW) and check that the servo moves the valve gear to the
forward position.
If it goes the wrong way you will need to reverse the mechanical connection. 
If the small knob wants to make the servo move too far put the connecting rod into a servo arm hole closer to the
middle of the servo arm. If it does not move far enough move the rod into a hole further out.
N.B DO NOT FORCE THE SERVO AGAINST THE STOP. DOING SO WILL DAMAGE THE SERVO.
1.4 Turn the small knob slowly and carefully to the left Counter Clockwise (CCW). With regards to any possible
mechanical changes you made during 1.3 above, it should perform correctly.
STEAM REGULATOR SERVO. 
2.1 Turn the large knob to the left (CCW) the servo will rotate CCW and should close the steam regulator valve.
If it goes the wrong way you will need to reverse the mechanical connection. 
If the large knob wants to make the servo move too far, i.e. over shutting the regulator, put the connecting rod into a
servo arm hole closer to the middle of the servo arm. If it does not move far enough move the rod to a hole further out.
N.B DO NOT FORCE THE SERVO AGAINST THE STOP. DOING SO WILL DAMAGE THE SERVO.
2.2 Turn the large knob to the right to check the servo opens the steam regulator far enough.
 IF MECHANICALLY CHANGING THE SERVO CONNECTIONS IS NOT POSSIBLE, RCS NOW HAS AN
AUTOMATIC BINDING DSM2 RX THAT CAN REVERSE SERVOS & ADJUST END POINTS ON 3 X CHANNELS.
3. DRIVING LIVE STEAM LOCOS.
Make sure the TX is OFF and the big knob is fully CCW. This is the same as the throttle stick on a conventional stick R/C
being fully down. Make sure the small knob is in the middle. You can feel the détente when twisting the knob.
Turn ON the loco before the TX-3v2 hand piece.
Once steam has been raised select the direction of valve gear with the small knob.
Then turn the big knob CW. That is like raising the throttle stick on a conventional stick R/C.
Turn the big knob CCW to slow the loco. All the way CCW will bring the loco to a stop.
You can have a faster stop by centering the valve gear control knob. Then make sure the big knob is also fully CCW.
The Bind button doubles as a whistle control with a servo on Ch # 5. It starts off at one extreme and when pressed goes
fully the other way. It snaps back to the start point when released. Ideal for controlling a servo whistle.

4. USING THE TX-3 WITH AN RCS “LOW OFF” ESC’.
N.B The TX-3 handpiece cannot be used for programming the Rx65-2 & ALPHA-3 ESC’s.
The TX-3v2 can be used with RCS BASIC “LOW OFF” ESC’s such as the ALPHA-3.
This TX-3v2 hand piece is essentially a 3 channel stick R/C in a smaller case using only three channels.
Make sure the large throttle knob is fully CCW (OFF) and small knob is centered before you switch the system on.
Switch on the ESC first & then the TX-3v2.
1. The large knob controls channel # 1 the throttle. Make sure the knob is fully CCW before switching on. This is the
same as the Channel # 1 stick being fully down.
2. The small knob is the same as the Ch # 3 elevator stick.
Turning the small knob CW is the same as pushing the elevator stick forwards.
Turning the small knob CCW is the same as pulling the elevator stick backwards.
USING ESC’s WITH AN ALPHA-3 ESC.
From neutral, set the small knob to the direction you want and leave it there.
Throttle must be at OFF before changing direction. Pause at neutral for one second when changing direction.

WHEN USED FOR “LOW OFF” MODE.
SET THE FORWARDS DIRECTION.
SET THE REVERSE DIRECTION.
5. USING THE TX-3 WITH A “CENTRE OFF” ESC’.
The TX-3v2 can be used intuitively with most of the centre off ESC’s that are available.
The small knob uses Ch # 3 to control both the direction & speed. It is most important that this large knob is centered
at the built in détente before switching the TX-3v2 on. The dot on the knob should face forward.
The large knob for setting the live steam regulator has no function when used with Centre Off ESC’s.
We use the # ALPHA-3v2-CO as is with the TX-3v2. The Ch # 5 Bind button is programmed as a sound trigger.
Make sure both the large throttle knob and small knob are centered before you switch the system on.
Switch on the ESC first & then the TX-3v2. Most Centre Off ESC’s calibrate themselves when switched on.
Twist the knob gently left or right until the loco starts moving.
The TX-3 has been designed so that normally twisting the knob to the right (CW) is forwards direction and movement.
If the loco runs backwards we reverse the motor wiring to correct the direction and maintain the standard.
Turn the knob back to the left to slow down. You can feel the détente as you arrive at neutral.
Then, once in neutral wait 1 x second before you can twist the knob to the left (CCW) to go backwards.
The bind button also controls Ch # 5. You can add a servo for mechanical operation. EG a Kadee servo uncoupler.
If the directional lights are incorrect, swap over the wiring to them so they match the loco speed and direction.
#ALPHA-3 ESC’s have directional lights and two sound triggers.
If your ESC does not have directional lights, RCS has a small add on module # 2-M-F that reads the speed & direction
of the Channel # 1 output & switches lights accordingly. A standard servo “Y” cable is needed. Not supplied.
