  • Page 6: Features

    DPSI RV Family Operating Instructions Version 2.0 2. Features A DPSI RV is used as a redundant power supply and current distributor for receivers and servos in RC-Models. The redundancy is accomplished by using two connected batteries. If one battery fails, the second battery guaranties safe operation.
  • Page 7 DPSI RV Family Operating Instructions Version 2.0 Voltage Regulation: Until now, the receiver set was supplied directly by the connected battery (or a corresponding battery switch). The output voltage depends heavily on the current discharge state. Because virtually always 5-cell NiCad or NiMH batteries are being used in large model airplanes, a fully charged battery reaches up to 7.5 volts after the charger shuts off (depending on the charging current and the internal resistance).
  • Page 8 DPSI RV Family Operating Instructions Version 2.0 Hint: On delivery, the DPSI RV system’s low voltage recognition is programmed for 2- cell LiPo batteries. For using other battery types, the corresponding type must be programmed first (see chapter 5.9)! The output voltage is set to 5.6 volts on delivery (DPSI 2001 RV 5.9 volts – other values on customer request possible).
  • Page 9 DPSI RV Family Operating Instructions Version 2.0 The DPSI 2001 RV is the enhancement of the DPSI 2001 and supplies 26 servos altogether, which result from 10 receiver channels. Therefore, it is predestinated for all kinds of large model airplanes, which need many servos (e.g.
  • Page 10 DPSI RV Family Operating Instructions Version 2.0 The DPSI RV Mini ESP versions (Extra Servo Power) correspond to the DPSI RV Mini 5 and 6, but possess 3 additional connectors, which carry the unregulated voltage of the batteries and therefore are applicable for consumer loads with higher output voltage (e.g.

  • Page 14: Ivm (Intelligent Voltage Monitoring)

    DPSI RV Family Operating Instructions Version 2.0 3.3. IVM (Intelligent Voltage Monitoring) An internal 8-bit microcontroller monitors all voltages by using an intelligent algorithm and shows various faults (overload, low voltage, voltage faults) acoustically by means of a built-in piezo buzzer. Furthermore, errors are displayed through blink codes of the LED in the switch transmitter.
  • Page 15 DPSI RV Family Operating Instructions Version 2.0 All commercial remote control systems (Graupner JR, Multiplex, Futaba) were successfully tested in all types of modulation (PCM, SPCM, PCM1024, PPM, IPD) in connection with the DPSI RV. Thus, all systems can be used trouble-free. The DPSI 2001 RV as well as the DPSI RV offers the option of connecting a second receiver.

  • Page 17: Installation Instructions And Programming

    DPSI RV Family Operating Instructions Version 2.0 5. Installation Instructions and Programming 5.1 Installing the DPSI RV The simplest method of installation is to glue the receiver directly to the DPSI RV using double-sided adhesive cellular rubber strips (5-10 mm thick).
  • Page 18 DPSI RV Family Operating Instructions Version 2.0 Since the DPSI (2001) RV is most often used in large models, it is advisable to fasten the entire package with rubber bands on 4 sides, oscillating freely in the fuselage (see photo). The DPSI RV Mini versions were developed for smaller models, which are narrower.

  • Page 19: Hole Spacing For Fastening

    DPSI RV Family Operating Instructions Version 2.0 Generally, you must always ensure that the fastening is as vibration- free as possible and has sufficient air circulation. Reduction of vibration is particularly important for the receiver, since it reacts far more sensitively to mechanical vibrations than the DPSI RV.

  • Page 20: Connecting The Switch Transmitter

    DPSI RV Family Operating Instructions Version 2.0 5.3. Connecting the Switch transmitter With a mechanical switch, one risks a breakdown. There are intense vibrations at the sidewall of the fuselage. Thus, malfunctions of mechanical switches were observed many a time. In order to avoid mechanical influences, electronically switches including self-holding circuitries are used in DPSI RV systems.
  • Page 21 DPSI RV Family Operating Instructions Version 2.0 A switch correctly mounted on the DPSI RV: DPSI RV switch transmitter: The central, ultra-bright light-emitting diode (LED) in the switch transmitter always illuminates when the DPSI RV is switched on (pin in the red On-socket).
  • Page 22 DPSI RV Family Operating Instructions Version 2.0 Two commercial battery controllers can be plugged directly to the backside of the switch using JR Uni-Connectors. The inscription “B1” stands for battery 1 and “B2” for battery 2. This enables additional optical voltage monitoring of the batteries. When using this type of battery controller, you must ensure that the required number of cells is correctly set.

  • Page 23: Connecting The Receiver

    DPSI RV Family Operating Instructions Version 2.0 5.4. Connecting the Receiver DPSI RV and DPSI RV Mini 5 / 6 Not all inputs of the DPSI RV need be contacted when connecting the receiver. Only the number of patch cables (cables between receiver and DSPI RV) required should be plugged in.
  • Page 24 DPSI RV Family Operating Instructions Version 2.0 Hint: The assignment of receiver channels according to the print image of the DPSI RV housing is just a suggestion! In any case, the assignment can be arbitrary. This means, receiver channel 1 must not necessarily be connected to channel 1 of the DPSI RV.

  • Page 25: Selecting The Batteries

    DPSI RV Family Operating Instructions Version 2.0 Two receivers on the DPSI RV: For all DPSI RV systems, servos can be connected to the receiver directly. This only makes sense for the “smaller” DPSI RV’s because these posses only 5, 6 or 10 inputs. Because all components of the receiver set (receiver and servos) are supplied with the same regulated voltage, the servo power and servo velocity stays the same (if of same type).
  • Page 26 DPSI RV Family Operating Instructions Version 2.0 Battery capacities Generally, ampacity and capacity of the batteries have to be considered. Thus, 2 battery packs with 450 mAh are much too small for e.g. 15 servos of a 3m (10 ft) model. Here, two “2000’s” should be used, which can be discharged (peak current) with 6C.
  • Page 27 LONGGO battery enables charging without having to disconnect the battery from the DPSI RV. Charging devices for the LONGGO batteries are also available from EMCOTEC. Selecting the output voltage We recommend 5.6 up to 5.9 volts for the entire receiver system (especially for servos approved for 6 volts).

  • Page 28: Soldering The Battery Connectors

    DPSI RV Family Operating Instructions Version 2.0 Hint: Due to the dropout losses in the constant voltage control of the DPSI RV systems, it is definitely NOT possible and not permissible to use 4-cell battery packs (NiCad/NiMH)! 5.6. Soldering the Battery Connectors The included Multiplex high-current sockets are marked + and –...

  • Page 29: Charging The Batteries

    Here, a “2S2P” battery is built up. The number of cells (voltage) stays the same; the charging current may be doubled. Corresponding charging cables are available at EMCOTEC. If charging LiPo batteries, which are connected to a DPSI RV system during charging, a charging device with a limiting step up converter is necessary.

  • Page 30: Setting The Voltage

    DPSI RV Family Operating Instructions Version 2.0 If in doubt, it is reasonable and safer to detach the batteries from the DPSI RV for charging. To do so, pull the plug from the holding clamps of the DPSI RV in zigzag movements and slightly tilted to the side (not applicable for DPSI 2001 RV).
  • Page 31 DPSI RV Family Operating Instructions Version 2.0 If needed, a small strip of adhesive tape (sticky tape or the like) protects the jumper from slipping out. Setting the voltage of the “DPSI RV Mini 5“ to 5.6 Volt: The jumper position is printed on the housing of each DPSI RV. Hint: The output voltage of the DPSI 2001 RV is fixed to 5.9 volts.

  • Page 32: Programming Of The Batteries

    DPSI RV Family Operating Instructions Version 2.0 5.9. Programming of the Batteries Since the DPSI RV executes intelligent battery voltage monitoring, the battery type being used must be made known to it (whether 5, 6 or 7- cell batteries or LiPo batteries are being used, for example). The type of battery only needs to be programmed once –...

  • Page 35: Connecting The Servos

    DPSI RV Family Operating Instructions Version 2.0 5.10. Connecting the Servos The DPSI RV Mini 5 (ESP) distributes 5 receiver channels to a total of 8 servos (3 V-cables “built in”). The DPSI RV Mini 6 (ESP) distributes 6 receiver channels to a total of 7 servos (1 V-cable “built in”).
  • Page 36 DPSI RV Family Operating Instructions Version 2.0 When using digital servos, it is very important to ensure that the heat sink cools well. Hint: Depending on the number and power of servos being used the overall current consumption of the system changes. The higher the overall current, the more energy will be transformed into heat.

  • Page 37: Connecting Accessories

    DPSI RV Family Operating Instructions Version 2.0 5.11. Connecting Accessories Operation of the DPSI RV with gyroscopes It is also possible to operate the DPSI RV using gyroscopes. In this case, you must ensure that the servo(s) is / are not attached to the gyroscope, but directly to the DPSI RV.

  • Page 38: Emcotec Filter Capacitor

    EMCOTEC filter capacitor (especially when using high power digital servos). The EMCOTEC filter capacitor is installed at an unused servo output (or at “Batt.”) directly at the receiver and makes sure, that peak voltages that can disturb the receiver are eliminated. Even short voltage dropouts will be effectively bypassed by this capacitor.

  • Page 39: Operation

    DPSI RV Family Operating Instructions Version 2.0 6. Operation To switch on the DPSI RV, the 2 mm (0.08”) pin plug is pulled from the disconnect socket (black) and plugged into the turn-on socket (red). The red, ultra light LED in the switch and on the circuit board of the DPSI RV (not DPSI 2001 RV) light up.

  • Page 40: Error Indication

    DPSI RV Family Operating Instructions Version 2.0 7. Error Indication The DPSI RV has an internal 8-bit microcontroller that constantly monitors all voltages. An intelligent algorithm ensures that low voltage of the connected batteries is detected not only by the short-term drop in voltage during movement of all servos.
  • Page 41 DPSI RV Family Operating Instructions Version 2.0 Error type 2 has the second highest priority and remains active until the DPSI RV is turned off. When using LiPo cells, a condition is reached where the batteries can be irreparably destroyed if not turned off immediately and if the batteries are not immediately charged.

  • Page 42: Safety Instructions

    DPSI RV Family Operating Instructions Version 2.0 Hint: The limits for detecting low voltage of the algorism are designed especially for the operation of RC flight models. When the DPSI RV is used for other applications, it is possible that incorrect information may be given. If this is the case, the error message (if it is perceived as disturbing) can be completely hidden (see “Programming of batteries”).
  • Page 43 DPSI RV Family Operating Instructions Version 2.0 Always ensure that you have fully charged batteries when operating your model. Empty batteries inevitably lead to failure of the RC components, which cause the model to crash. Do not expose the DPSI RV to any extremely hot or extremely cold temperatures, moisture or humidity.
