PREPARING THE # DU-Tx5/7-PLUS HANDPIECES.
THESE INSTRUCTIONS REFER TO THE RCS # DU-Tx5/7-PLUS 2.4 GHz 5 CHANNEL R/C.
The procedures on pages 2, 3 & 4 apply to all DUAL USE handpieces.
Placing knobs on Tx handpiece case.
Normally, the small Reverser knob is on the Right. The Large Steam Regulator knob is on the Left.
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 unplugging the servos from the Rx in case they are not correctly adjusted. Adjust servo
parameters after binding has taken place. KEEP THE TX HANDPIECE AT LEAST ONE METRE FROM THE LOCO.
HOW TO “BIND” USING ALL RCS AUTO BINDING DSM2 Rx’s.
1.1 With transmitter switched OFF. Set all knobs in the middle idle position.
1.2.Turn the Rx ON. The servos will snap to pre-set positions depending whether Low OFF or Centre OFF.
Centre OFF = All servos go to neutral. After Binding Ch # 5 snaps to fully CCW.
Low OFF = Chan # 1 servo goes to fully CCW. After Binding Ch # 1 snaps to back to middle position idle.
The # CPU-LED will blink slowly during binding. The # RF-LED will be OFF. (See Rx instructions).
1.3. Wait 5 seconds and the RF-LED on Rx will start blinking very rapidly to indicate it is ready to be bound.
If you cannot see the RF-LED wait 10 seconds to start Binding.
ON OFF SWITCH PRESS & HOLD BIND THEN TURN ON.
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 effective binding to take place.
1.5 Then press and hold the ON –OFF button to ON. Hold both buttons until the RF-LED stops flickering & then
blinks a couple of times. Then let both Tx buttons go. The Tx button also blinks slowly & then goes to solid ON.
1.6 After 10 seconds the RF-LED on all Rx’s will blink twice. After about another 5 seconds both LED’s on the Rx will
come on solid and “BINDING” is complete. If using # AB-Rxv2-EM/TM rx’s, servos will snap to pre-set positions.
Refer to Manual Bind Rx instructions for how to bind etc. Remove Bind Plug before using Rx.
Directional Constant brightness lighting. RCS # AB-Rxv2-EM/TM Auto bind RX’s have lighting outputs.
# LM-0034E/T very Basic RX’s do not. For Live Steam you can use a “Y” cable to drive an R/C switch such as the #
MRW-SSLS on Ch # 3 as well as the Reverser servo. The Reverser knob can then control both functions.
# Ch # 5 Sound Trigger. This is available when using a Low OFF or Centre OFF ESC.
Or, you can use the small reverser knob & an R/C switch for two more sound triggers if using only a Centre OFF ESC.
See page # 8 for R/C sound trigger options.
Cruise Control. It is quite OK to turn the TX handpiece OFF and allow the loco to continue cruising at the set speed
until the Tx handpiece is turned on again.
Be aware that when turning the Tx handpiece back ON, relinking can take a few seconds.

2. PREPARING FOR USE WITH LIVE STEAM LOCOS.
The procedures on pages 2, 3 & 4 apply to all DUAL USE handpieces.
All knobs and pushbuttons will have 100% (90°) servo throw. This will suit most situations.
The # AB-Rxv2-EM/TM has adjustable servo default rotation and variable end points. See the # Rx instructions.
ADJUSTING SERVOS USING # AB-Rxv2-EM/TM Rx’s. (Requires the use of # PIN-8-PB cable assembly.).
Make sure the Rx is OFF. Then turn the handpiece ON. Then re-insert the servos into the correct Rx sockets.
Valve gear servo goes in Ch # 3 (Small knob) socket. The regulator servo is controlled by Channel # 1 (Big knob).
You can swap the knobs & servo connections to have Left or RH one handed operation.
Be careful selecting the correct terminal. They are marked on the back of the DSM2-AB Rx-v2’s.
When using for the first time make sure both knobs are centered. Both Tx knobs have a centre detent click.
VALVE GEAR REVERSER 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.
If it goes the wrong way you will need to reverse the mechanical connection. OR fit an inline servo reversing module.
1.3.Turn the reverser knob slowly to the right Clockwise (CW) and moves the valve gear to the forward position.
If it goes the wrong way you will need to reverse the mechanical connection. OR fit an inline servo reversing module.
If the reverser 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 servo arm hole further out.
Another way to adjust end points is to fit an # MRW-11 module.
N.B DO NOT FORCE THE SERVO AGAINST THE STOP. DOING SO WILL DAMAGE THE SERVO.
1.4.Turn the reverser 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 regulator 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, OR. See 1.3 above.
If the large knob wants to make the servo move too far, i.e. over closing the regulator, put the connecting rod into a
servo arm hole closer to the middle of the servo arm. Does not move far enough, move the rod to a hole further out.
2.2. Turn the large knob to the right to check the servo opens the steam regulator far enough.
3. DRIVING LIVE STEAM LOCOS.
Make sure the Tx & Rx are both OFF and the regulator knob is fully CCW. This is the same as the throttle stick on a
conventional stick R/C being fully down.
Ensure the reverser knob is in the middle. Turn ON the # DU-TX5-PLUS hand piece and then the loco.
Once steam has been raised, select the direction of valve gear with the CH # 3 reverser knob.
Then turn the regulator 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 reverser control knob. Then make sure regulator knob is fully CCW.
The Ch # 5 Bind button.
For Live Steam the Ch # 5 doubles as a whistle control with a servo. It starts at one extreme & when pressed goes
fully the other way. It snaps back to the start point when released. Controls a servo operated steam whistle. OR:
For Battery R/C. When the Ch # 5 button is combined with a suitable R/C switch, plugged into the Rx, the button
can be used as a sound trigger. EG, the latest MyLocosound features a diesel engine START –STOP feature.
Also suitable for controlling Kadee®servo uncoupler’s.May require a # SIG-REV as default direction is back to front.

4. USING THE # DU-Tx5-PLUS WITH A “CENTRE OFF” ESC.
The procedures on pages 2, 3 & 4 apply to all DUAL USE handpieces.
The # DU-TX5-PLUS is ideal for use with CENTRE OFF ESC’s such as the COBRA-260 & VIPER ESC’s.
Before you switch the system on, make sure the large throttle knob is in neutral. i.e. at the centre “click”.
For only one loco, the direction knob will not be used. It could be used for another Centre OFF ESC on Ch #3.
CENTRE OFF CONTROL.
FORWARDS - SPEEDING UP.
To select forwards direction, twist the knob from neutral slowly clockwise (CW) to the right.
SLOWING DOWN. Turn the knob back to the left (CCW) to set desired speed.
STOPPING.Completely stop the loco by bringing the knob back to neutral.
REVERSE - SPEEDING UP.
To select reverse direction, twist the knob slowly to the left (CCW).
SLOWING DOWN. Turn the small knob back to the right (CW) to set desired speed.
STOPPING. Completely stop the loco by bringing the small knob back to neutral.
SHUTTING DOWN. When you have finished operating, turn off the loco(s) before the TX.
NEUTRAL OFF POSITION OF THE TX-1
IN “CENTRE OFF” MODE.
SET THE DIRECTION
& SPEED CONTROL.
DU-TX5 SET UP FOR OPPOSITE
THUMB CONTROL.
If the loco runs backwards, we reverse the motor wiring to correct the direction and maintain the standard.
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.
5. USING THE # DU-Tx5-PLUS WITH AN RCS “LOW OFF” ESC.
The # DU-TX5-PLUS handpieces can be used with LOW OFF ESC’s.
Operation is essentially the same as for Live Steam control. See page # 3 for pics and text.
This # DU-TX5-PLUS hand piece is a 5 channel stick R/C in a smaller case.
Make sure the large throttle knob is fully CCW (OFF) and small knob is centered before you switch the system on.
Switch on the # DU-Tx5-PLUS first & then the ESC. (Unless binding)
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 a Ch # 3 elevator stick.
Turning the small knob to the right (CW) is the same as pushing the elevator stick forwards.
Turning the small knob to the left (CCW) is the same as pulling the elevator stick backwards.
3. From neutral, set the small knob to the direction you want. CW for forwards.
4. Twist the large throttle knob to the right (CW) to accelerate.
5. To slow down twist the large knob to the left (CCW) until desired speed is reached.
6. To stop loco turn the large knob fully to the left (CCW).
Throttle must be at OFF before changing direction. Twist the small knob CCW once to return loco to neutral.
7. To select reverse direction Then twist it again CCW.
To speed up, slow down & stop in reverse, repeat steps 4, 5, 6, & 7.

USING THE #DU-Tx5-PLUS
THESE INSTRUCTIONS REFER TO THE RCS DU-Tx5-PLUS 2.4 GHz 5 CHANNEL R/C.
LAYOUT OF THE # DU-Tx5-PLUS TRANSMITTER HAND PIECE.
These two knobs on top row control Ch # 2 on the Left and Ch # 4 on the right.
The # DU-Tx5-PLUS is mostly used with Live Steam locomotives. The two extra knobs provide two fully proportional
outputs on Ch # 2 & Ch # 4. All knobs do have a centre detent.
They each provide full servo movement for use with drain cocks, blowers, gas control, open/close firebox door etc.
The # DU-Tx5 is not generally used for battery R/C locos. However those two knobs can give two sound triggers per
channel, when combined with a suitable R/C trigger such as the # MRW-SSDS. This device will provide dual
electronic R/C triggers on electronic sound systems such as MyLocosound or Phoenix.
For three triggers use the # MRW-SSTS. Three individual triggers. One trigger on each channel
For four triggers use the # MRW-SSQS. Two lots of two triggers on each knob.
All servo channels have 100% (90°) throw. Specifically 1.05 ms - 1.50 ms - 1.95 ms
Swapping the knobs around does not increase or decrease servo throws for Live Steam models.
Replacing the large knob with the supplied smaller one, radically changes what you can do with the handpiece.
Users now have the opportunity to have FOUR centre OFF battery R/C locos on one handpiece.
OR. Two Low OFF ESC equipped locos from the one handpiece.
OR. Two Centre OFF ESC equipped locos each with two sound triggers using the top two knobs.

USING THE #DU-Tx7-PLUS
THESE INSTRUCTIONS REFER TO THE RCS # DU-Tx7-PLUS 2.4 GHz 4 CHANNEL R/C.
LAYOUT OF THE # DU-Tx7 TRANSMITTER HAND PIECE.
The case front is similar to the # DU-Tx5shown earlier.
There are two pushbuttons on each of Ch # 2 & Ch # 4.
The # DU-Tx7-PLUS is intended for use with battery R/C locos.
It suits both Centre OFF and Low OFF type ESC’s.
There are four dedicated sound trigger functions that mate up with an appropriate # MRW plug IN R/C Switch.
These are available separately anduse channels # 2 & 4.
For battery R/C locos, the two single function pushbuttons use either one # MRW-SSSS for channel # 5 plus a quad
trigger switch # MRW-SSQS for all F1 –F4 functions.
You could use two # MRW-SSDS triggers if you wanted to. See page # 8.
By replacing the large knob with the supplied small knob the handpiece becomes a DUPLEX type and can control 2 x
Centre OFF locos at the same time. Each with two sound triggers.
When used with Live steam locomotives the two pushbuttons provide snap actions for servos on Ch # 2 & Ch # 4.
********************************************************************************************************
CENTERING CH # 1 ON THE Tx HANDPIECE.
The following applies to all five DUAL USE handpieces.
The # DU-Tx battery will eventually go flat if left switched on. The operating program may be disrupted.
The Ch # 1 centering on the # TX-PLUS system will need to be reset;
1.) Centre the Ch # 1 knob.
2.) Press the ON –OFF button to turn the # DU-Tx ON. LED light will come ON.
3.) Within 60 seconds, press and hold the bind button for 20 seconds.
4.) After 20 seconds the # DU-Tx ON –OFF LED light will go off.
5.) Release Bind button.
6.) LED light will come back ON. Centre reset is complete.
ALWAYS COMPLETE THE ABOVE PROCEDURE WHEN REPLACING THE 9 VOLT BATTERY.
