Other instructions for use with battery R/C are found with the ESC. http://www.rcs-rc.com/pages/instructions Thank you for purchasing this DSM2 5 channel TX handpiece. Please note the name had to be changed from TX20-LS to TX-2s. THE PRIMARY PURPOSE OF THE TX-2s IS FOR CONTROLLING LIVE STEAM LOCOS. THE SECONDARY PURPOSE IS FOR USE WITH CENTRE OFF ESC s. WE DO NOT RECOMMEND USING THE TX-2s WITH RCS ESC s, BUT THEY CAN BE WITH COMPROMISES. INSTRUCTION MANUAL THESE INSTRUCTIONS REFER SPECIFICALLY TO THE DELTANG R/C BASED TX-2s HANDPIECE. They should be read in conjunction with the RCS ESC you are using. WHEN USED FOR LIVE STEAM A SMALL KNOB SETS THE VALVE GEAR. 300º KNOB CONTROL OF REGULATOR. 2 X ½ SERVO MOVEMENT FUNCTIONS. 1 X FULL MOVEMENT SERVO. REMOVE REAR OF TX-2S TO INSERT THE 9 VOLT BATTERY. WHEN USED AS A CENTRE OFF CONTROLLER THE LARGE KNOB IS USED FOR SETTING DIRECTION & SPEED. THERE ARE TWO PUSHBUTTONS FOR ACCESSORY FUNCTIONS. PRIMARY USE IS WITH LIVE STEAM LOCOS. CAN ALSO BE USED WITH ANY CENTRE OFF ESC. THE TX-2s IS GUARANTEED FOR ONE YEAR. When used for battery R/C you will supply a locomotive or trail car, the 14 20 volt traction batteries (depending on ESC), a fuse, ON-OFF switch and wires where necessary, to connect the ESC to the battery and motor(s). Where soldering is necessary, we recommend a low wattage soldering iron and resin core solder. TO AVOID CONFUSION WITH OTHER OPERATORS, WE SUGGEST YOU MARK THE TX TO SHOW WHICH LOCO IT IS OPERATING. CAUTION DO NOT ATTEMPT TO ALTER THE TUNING OF THE RADIO EQUIPMENT. DO NOT USE RADIO CONTROL EQUIPMENT IN THUNDERSTORMS. CHILDREN UNDER 12: ADULT SUPERVISION RECOMMENDED DURING USE.
2 PREPARING THE #TX-2s THESE INSTRUCTIONS REFER TO THE RCS TX-2s 2.4 GHz 5 CHANNEL R/C. LAYOUT OF THE TX-2s TRANSMITTER HAND PIECE. The valve gear knob is in the upper middle. The steam regulator knob sits just below. Top left is the ON OFF switch. Top right is the Bind/Ch # 5 pushbutton. The F1 function trigger pushbutton is on the left. The F2 function trigger pushbutton is on the right. 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. HOW TO BIND USING A DSM2 RX OR RCS #BASIC-3 ESC. 1.1 LIVE STEAM. 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. 1.1 #BASIC-3 ESC s See 1.2 below. Turn on the loco power >RX and wait 20 seconds for the RX to enter bind mode. RX LED will flash rapidly OR; 1.1 OTHER ESC s. See Live Steam above. 1.2 Turn the loco RX ON. The RX LED will start blinking very rapidly to indicate it is ready to be bound. 1.2 Turn on the loco power >RX and wait 20 seconds for the RX to enter bind mode. RX LED will flash rapidly 1.3 Press and hold the right pushbutton on the handpiece marked with a hexagonal symbol. 1.4 Then press the ON OFF button to ON. Then let both buttons go. ON-OFF button will illuminate and blink slowly a couple of times then go solid ON. 1.5 The LED on the RX will blink more slowly and then go solid ON. 1.5 The LED on the DELTANG ESC will behave the same. 1.6 When BINDING is complete the RX LED will change to solid ON. N.B. BINDING plug MUST be removed BEFORE the SYSTEM is turned OFF. (#BASIC-3 has 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)
- 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. 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, THERE IS A SUITABLE LOW COST IN LINE SERO REVERSING MODULE AVAILABLE FROM RCS. 3. DRIVING LIVE STEAM LOCOS. Make sure the RX 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 detente. Then turn ON the TX-2s hand piece before the loco. 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. Two function buttons can be used to control half servo movement functions. Perhaps triggering a sound system. It is possible to have directional head & tail lights with the addition of a # 2-M-F connected in parallel with the valve gear servo on Ch # 3. How to wire that feature is shown in the # 2-M-F instructions. NEUTRAL OFF POSITION OF THE TX-2s FOR LIVE STEAM. SETTING THE VALVE GEAR FOR FORWARDS. SETTING THE VALVE GEAR FOR REVERSE.
- 7-4. USING THE TX-2s WITH AN RCS LOW OFF ESC. The TX-2s can be used with RCS LOW OFF ESC s such as the OMEGA-3 & PnP. This TX-2s hand piece is essentially a 5 channel stick R/C in a smaller case. 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 knob CCW is the same as pulling the elevator stick backwards. Just remember, you use the knob exactly the same as the elevator stick, except, you must return it to neutral when having set the direction etc. The F1 button controls output # 2 on the RCS ESC. The F2 button controls output # 4 on the RCS ESC. 5. USING THE TX-2s WITH A CENTRE OFF ESC. The TX-2s can be used intuitively with most of the centre off ESC s that are available. The large knob uses Ch # 1 to control both the direction & speed. It is most important that this large knob is centred at the built in détente before switching the TX-2s on. The dot on the knob should face forward. The small knob for setting the live steam valve gear has no function when used with Centre Off ESC s. That frees up Ch # 3 for the addition of another centre off ESC. The motor drive output of another #BASIC-3 ESC s can be re-assigned to Channel # 3 so the TX-2s can control two locos at the same time. You can have one sound trigger with each loco.. Make sure both the large throttle knob and small knob are centered before you switch the system on. Switch on the TX-2s first & then the ESC. Most Centre Off ESC s calibrate themselves when switched on. Twist the knob gently left or right until the loco starts moving. The TX-2s 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 you can twist the knob to the left (CCW) to go backwards. NEUTRAL OFF POSITION OF THE TX-2s IN CENTRE OFF MODE. MAXIMUM SPEED WHEN TRAVELLING FORWARDS MAXIMUM SPEED WHEN TRAVELLING BACKWARDS If the directional lights are incorrect, swap over the wiring to them so they match the loco speed and direction. #BASIC-3 ESC s have directional lights and two sound triggers. The following is not applicable to #BASIC-3 ESC s. If your ESC does not have directional lights RCS has a small add on module # 2-M-F that reads the speed and direction of the Channel # 1 output and switches lights accordingly. A standard servo Y cable is needed. Not supplied. The other functions are likely the same as they are for RCS if your centre off ESC has them fitted. If there are no sound triggers you can add another # 2-M-F to Channel # 2 for one more sound trigger. Add another # 2-M-F to channel # 4 for one more sound trigger. OR: Add 1 more # 2-M-F to channel # 3 for two sound triggers controlled by the spring loaded switch. The bind button also controls Ch # 5. You can add a servo for mechanical operation. EG a Kadee servo uncoupler. SEE THE SEPARATE ESC DIAGRAM INSTRUCTIONS FOR HOW TO WIRE A PARTICULAR BRAND.
