- Page 3 RC model. As a matter of course, the “DPSI RV / RV Mini“ was subjected to an intensive flight test in addition to extensive laboratory tests. We thus carried out costly series of tests, for example, with data loggers that were specially developed for measuring the actual power consumption in model airplanes.
- Page 4 Operating Instructions Version 1.1 2. Features The “DPSI RV / RV Mini“ is used as a redundant power supply and distribution for receivers and servos (steering gear) in RC models. Redundancy is achieved by means of two connected storage batteries.
- Page 5 7.4 V (as much as 8.4 V after charging), which was previously unsuitable for receiver applications. This changes in the case of the “DPSI RV / RV Mini“, which is specially designed for using these cells. The advantages of the lithium polymer...

- Page 10 RV Mini“ is not damaged. A servo cable that is accidentally short-circuited will generally burn out or melt, without damaging the “DPSI RV / RV Mini“ (in the case of thick cable diameters, however, the strip can also be affected, since the „permissible“...
- Page 11 Version 1.1 To enable optical switch-on control, an ultra-bright light-emitting diode was installed into the switch of the “DPSI RV / RV Mini“. This signals that the system is turned on, even at great distances. 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 / RV...
- Page 12 DPSI RV / RV Mini Operating Instructions Version 1.1 Scope of supply of the “DPSI RV Mini” & „DPSI RV Mini LDO“: “DPSI RV Mini” basic device “DPSI RV” On/Off switch 5 each receiver connection cables (with servo-plugs on both sides)
- Page 13 In the case of very high current (a large number of servos) and under competitive conditions, the upper side of the “DPSI RV / RV Mini“ should always remain open to allow for unobstructed dissipation of heat.
- Page 14 DPSI RV / RV Mini Operating Instructions Version 1.1 Since the “DPSI 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).
- Page 15 Even if the pin should get lost, the „DPSI RV / RV Mini“ remains switched on (in switched-on mode). The „DPSI RV / RV Mini“ can only be switched off if the pin plug is plugged into the off socket. Of course a pin plug may not be plugged into every socket, even though this does not damage the “DPSI RV /...
- Page 16 A drilling jig for the switch is included with these instructions. The connection cable with plug is plugged into the respective multiple plug of the “DPSI RV / RV Mini“ until it locks into place on impact (see photo). In the event that replacement or removal is necessary, the plug can be disengaged from the multiple plug by carefully pulling it out parallel (take hold of the cable directly at the plug).
- Page 17 DPSI RV switch: The central, ultra-bright light-emitting diode (LED) in the switch always illuminates when the „DPSI RV / RV Mini“ is switched on (pin plug in the red On-socket). Two commercial battery controllers can be plugged directly to the backside of the switch.
- Page 18 Version 1.1 5.3. Connecting the Receiver Not all of the 12 or 5 inputs of the „DPSI RV / RV Mini“ need be contacted when connecting the receiver. In both cases the supplied cable is sufficient for all DPSI inputs – however, only the number of cables (channels) required should be plugged in.
- Page 19 “Longgo” batteries may also be used. The number of cells of the storage batteries being used complies with the output voltage. The control electronics in the „DPSI RV / RV Mini“ results by principle in a loss voltage, which is converted to heat. This loss voltage must be added to the selected output voltage.
- Page 20 For applications for which only 5 cells (NiCd or NiMH) should be used, but an output voltage of 4.8 V is too low, the “DPSI RV LDO / RV Mini LDO“ can be used as an alternative. “LDO” stands for LowDropOut (low loss of voltage).
- Page 21 (and micro-controllers) “cope better” with this voltage. Note: The output voltage of the “DPSI RV / RV Mini” should only be set to 5.5 V even with 6 V servos (for 4.8 V servos to 4.8 V or a maximum of 5.2 volts).
- Page 22 The power handling capacity of this type of cable is at a maximum of 2.5 A. With a theoretical current of 10 A, the drop in voltage in this cable is already 0.5 V. Instead of 6.0 V reaching the „DPSI RV / RV Mini“, for example, there are now only 5.5 V.
- Page 23 Soldering the Multiplex socket: Note: The „DPSI RV / RV Mini“ is not reverse polarity protected due to type of construction! Please ensure that the batteries are always correctly connected, i.e. the red line must always be at the plus and the black line always at the minus.
- Page 24 “DPSI RV / RV Mini“. In order to enable charging of the battery, even if it is connected to the “DPSI RV / RV Mini”, a second cable must be soldered to the battery, or the battery must be connected by means of a V-cable.
- Page 25 – depending on the output voltage - are coded and plugged to the strips of the “DPSI RV / RV Mini”. It is best to use tweezers or a small pincer for this purpose. A small strip of adhesive tape (Tesa or the like) protects the jumper from slipping out.
- Page 26 This displays the operating mode “programming”. Following this is a one-time beep, which displays “Battery type No. 1”. If, at this point, the missing battery is connected to the “DPSI RV / RV Mini“ within three seconds, this „Battery Type No. 1“ is selected and will be programmed.
- Page 27 At delivery, “Battery type No. 4” (the Longgo battery) is programmed by default. When “5 beeps” is selected (all tests deactivated), the “DPSI RV / RV Mini“ does not carry out any voltage tests. Therefore, no empty batteries or other faults are acoustically notified.

- Page 29 Version 1.1 5.9. Connecting the Servos The “DPSI RV” distributes 12 servo outlets of the receiver on a total of 32 servo connections. The “DPSI RV Mini” distributes 5 servo outlets of the receiver on a total of 8 servo connections.
- Page 30 Version 1.1 Connection scheme of the “DPSI RV Mini”: In this example, a total of 8 servos are connected to the “DPSI RV Mini“, while the remaining throttle servo is connected directly to the receiver. For all servos attached to the “DPSI RV Mini“, the pulse cable is at the bottom (as specified by the plug-in direction (beveled nose) of the housing).
- Page 31 Version 1.1 Safeguarding the servo connection cable: Many pilots fear that the servo cables attached to the “DPSI RV / RV Mini“ can become loose from vibration and that this would then lead to a malfunction. This type of occurrence has not yet been observed (not even in the case of intense vibrations).
- Page 32 It is also possible to operate the “DPSI RV / RV Mini” using gyroscopes. In this case, you must ensure that the servo(s) are not attached to the gyroscope, but directly to the “DPSI RV / RV Mini“. The gyroscope is connected to the existing circuit directly between the “DPSI RV / RV Mini“...
- Page 33 (see technical data). 5.11. Operation To switch on the “DPSI RV / RV Mini“, the 2 mm pin plug is pulled from the disconnect socket (black) and plugged into the turn-on socket (red). The LEDs in the switch and on the circuit board of the “DPSI RV / RV Mini“...
- Page 34 1. Overload (short circuit): Error signal: Continuous beep If the power consumption of the “DPSI RV / RV Mini“ becomes too high, a continuous buzz tone is emitted. In this case there is an external short circuit, which can lead to destruction of the “DPSI RV / RV Mini“...
- Page 35 Version 1.1 Error type 2 has the second highest priority and remains active until the “DPSI RV / RV Mini“ is turned off. When using Longgo cells (LiPoly), a condition is created whereby the batteries can be irreparably destroyed if not turned off immediately and if the batteries are not immediately charged.
- Page 36 6.0 V is selected, but only 5 cells are connected to the “DPSI RV / RV Mini“, it will not be possible to actually generate 6.0 V at the output (due to the drop-out losses; see also “Selecting the batteries“).
- Page 37 The “DPSI RV / RV Mini“ must be protected from humidity and moisture. The “DPSI RV / RV Mini“ must be located at a sufficient distance from neighboring surfaces to enable good heat dissipation of the cooling element.
- Page 38 DPSI RV / RV Mini Operating Instructions Version 1.1 Do not expose the “DPSI RV / RV Mini“ to any extremely hot or extremely cold temperatures, moisture or humidity. This would lead to danger of malfunction, damage or decreased efficiency.
