DPSI RV Family Operating Instructions Version 2.1 3. 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. In the normal case, both batteries are discharged simultaneously. Furthermore, current is cut in half in each of “parallel” connected single battery.
DPSI RV Family Operating Instructions Version 2.1 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 2-cell LiPo batteries are being used in large model airplanes, a fully charged battery reaches up to 8.4 volts after the charger shuts off (depending on the charging current and the internal resistance).
DPSI RV Family Operating Instructions Version 2.1 Hint: On delivery, the DPSI RV system’s low voltage recognition is programmed for 2cell LiPo batteries. For using other battery types, the corresponding type must be programmed first (see chapter 6.9)! The output voltage is set to 6.0 volts on delivery (DPSI 2001 RV 5.9 volts – other values on customer request possible).
DPSI RV Family Operating Instructions Version 2.1 The DPSI RV allows for connecting of up to 32 servos, which result from 12 receiver channels. Especially large-glider- and airliner-pilots missed this variety. Due to the higher number of servos, the DPSI RV is a little larger and heavier then the smaller systems. Because more heat dissipation is encountered, a larger heat sink is necessary. The DPSI RV contains two complete separate current paths and voltage regulators.

DPSI RV Family Operating Instructions Version 2.1 High grade plastic injection molding with integrated brackets for the battery connectors Large surface heat sink for deduction of lost heat Each system 100% tested and provided individual serial number Developed and manufactured by market leader (Made in Germany) DPSI Version DPSI 2001 RV DPSI RV Power Semiconductor 7 Max.
DPSI RV Family Operating Instructions Version 2.1 4.2. APP (Advanced Push Pull Servo Pulse Amplification) Each servo is provided with optimally prepared amplified pulses from the receiver. Servo signals usually are weakened if servo cables are connected in parallel (V-cable), which makes them interference prone. The servo pulses stay fully maintained in DPSI RV systems, even if four servos are connected on one channel.
DPSI RV Family Operating Instructions Version 2.1 4.4. Safety Features of the DPSI RV Systems Short circuits on the servo signal wires, regardless of whether they are toward the positive or negative wire of the servo cable, do not result in damage to the DPSI RV. All other servos of the channel in which the short circuit occurs remain fully functional. Even if the servo’s polarity is reversed, the DPSI RV is not damaged.
DPSI RV Family Operating Instructions Version 2.1 The DPSI 2001 RV as well as the DPSI RV offers the option of connecting a second receiver. Both receivers should be of identical type (the type of modulation must always be the same). We recommend the DPSI TWIN for complete redundancy of the receiver set. Due to the elaborated safety properties in connection with extensive tests, operating errors and external influences usually do not lead to damage of the DPSI RV. 5.
DPSI RV Family Operating Instructions Version 2.1 6. Installation Instructions and Programming 6.1. Installing the DPSI RV The simplest method of installation is to glue the receiver directly to the DPSI using double-sided adhesive cellular rubber strips (5-10 mm thick). The receiver can also be attached separately; this is the preferred method when using 2.4GHz receivers.
DPSI RV Family Operating Instructions Version 2.1 Generally, you must always ensure that the fastening is as vibrationfree 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. An approved method is to mount the DPSI to a mounting board between 4 short gas hoses and M4 screws. These serve as outstanding vibration dampers and allow for neat mounting (see photo).

DPSI RV Family Operating Instructions Version 2.1 6.3. 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 systems. The electronically switches are only controlled by a pulse from the external switch actuator.
DPSI RV Family Operating Instructions Version 2.1 The receiver set is turned on and off using a pin, which just delivers an on / off signal. Putting the pin into the on-socket (red) turns the DPSI on. Putting the pin into the off-socket (black) turns it off. The DPSI stays turned on, even if the pin gets lost. A DPSI only turns off by placing the pin into the off socket (i.e. moved)! DPSI pin switch actuator: Hint: In the case of a lost pin, you can help yourself by using a 2 mm (0.
DPSI RV Family Operating Instructions Version 2.1 A switch correctly mounted on the DPSI RV: Magnetically Switch Actuator (Housing): Optionally, there is a magnetically switch actuator available. Hover the magnet for about 1 second above the on-position of the switch actuator to turn the device on (green marking on plastic housing). For turning off hold the magnet for approximately 2 seconds close to the opposite mark of the switch actuator.
DPSI RV Family Operating Instructions Version 2.1 The central, ultra-bright light-emitting diode (LED) in the switch transmitter always illuminates when the DPSI is switched on. In case of an error (e.g. low voltage) or during programming the LED indicates the states through different blink codes. 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.
DPSI RV Family Operating Instructions Version 2.1 Gas Cap Switch Actuator (magnetically): Alternatively a gas cap switch actuator is available. The design mimics a gas cap. Here too, switch is done with a magnet. Pulling it off turns on, plugging in turns off. 6.4. Connecting the Receiver Connect the receiver with provided patch-cables to the DPSI (see print on housing). Not all inputs must be used when connecting the receiver. Only connect that many patch-cables as required.
DPSI RV Family Operating Instructions Version 2.1 Hint: In the case that the system does not work properly, please check whether all cables are plugged in correctly and if the type of modulation of the transmitter corresponds to that of the receiver. Hint: The assignment of receiver channels according to the print image of the DPSI 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.
DPSI RV Family Operating Instructions Version 2.1 6.5. Selecting the Batteries All commercially available batteries are considerable (NiCd and NiMH), as well as Lithium-Ion (LiIon) and Lithium-Polymer (LiPo) or LithiumFerrum-Phosphat (LiFePO4) batteries. These batteries are unlimited applicable independent of the selected output voltage. Even 6-cell (and 7-cell) NiMH batteries can be connected. This only makes sense if the output voltage of the DPSI is set to high values (7.
DPSI RV Family Operating Instructions Version 2.1 If for center of gravity purposes, the batteries are to be placed far away from the DPSI (i.e. long connection cables), it is advisable to twist the cables of the batteries. We recommend using our EMC Lithium Polymer batteries. These are supplied completely cabled and can be attached immediately to the DPSI. An additional charging connector at the battery enables charging without having to disconnect the battery from the DPSI.
DPSI RV Family Operating Instructions Version 2.1 6.6. Soldering the Battery Connectors The included high-current sockets are marked + and – on the solder side. It is imperative to observe this marking! The cable is first stripped about 5 mm (0.2 inch) and then tin-plated. Before soldering to the socket, the included heat-shrinkable sleeve must be pushed over the respective cable.
DPSI RV Family Operating Instructions Version 2.1 6.7. Charging the Batteries All DPSI systems switch on the batteries positive pole, i.e. both batteries are, if connected to the DPSI RV, connected together by the negative (ground) pole. Simultaneous charging is not always possible because most chargers which possess several charging outputs, measure using the negative line but join the positive wires.
DPSI RV Family Operating Instructions Version 2.1 6.8. Setting the Voltage The output voltage of the DPSI RV can be set in 4 steps for the receiver as well as the servos. This is done using the provided jumper, which – depending on the output voltage - is plugged to the coding strip of the DPSI. It is best to use tweezers or a small pincer for this purpose. Setting the voltage for receiver and servos to 5.
DPSI RV Family Operating Instructions Version 2.1 Hint: DPSI RV systems which were manufactured prior of June 2006 the output voltage is slightly different: 4.8V, 5.2V, 5.5V and 6.0V were available. Available output voltages are printed on top of the housing. DPSI RV systems which were manufactured prior of January 2010 the output voltages is also different: here 5.0V, 5.3V, 5.6V and 5.9V are available. Available output voltages are printed on top of the housing. 6.9.
DPSI RV Family Operating Instructions Version 2.1 This principle is repeated until the buzzer has beeped five times (deactivate all tests). If the missing battery is not attached within three seconds, no programming is done and the system changes to the normal operating mode.

DPSI RV Family Operating Instructions Version 2.1 6.10. Connecting the Servos The DPSI 2001 RV distributes 10 receiver channels to a total of 26 servos (8 multiple V-cables “built in”). The DPSI RV distributes 12 receiver channels to a total of 32 servos (8 multiple V-cables “built in”). For this purpose, a distribution that enables a number of combinations has been selected. When using digital servos, mind good air ventilation for the heat sink.
DPSI RV Family Operating Instructions Version 2.1 6.11. Connecting Additional Products Operation of the DPSI RV with gyroscopes It is also possible to operate the DPSI using gyroscopes. In this case, you must ensure that the servo(s) is / are not attached to the gyroscope, but directly to the DPSI. The gyroscope is connected to the existing circuit directly between the DPSI and the receiver. Example: The gyroscope is to be connected to channels 2 and 5 of the receiver (for the ailerons).
DPSI RV Family Operating Instructions Version 2.1 6.12. EMCOTEC Filter Capacitor Using powerful digital servos can cause these to induce extremely high peak voltages (counter electro automotive force) which, under certain circumstances damage the receiver or “crash” the microcontroller in the receiver. Because of their dimensions, filter capacitors built into the receivers often do not suffice to eliminate these disturbances.
DPSI RV Family Operating Instructions Version 2.1 7. 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. This signals operation. Immediately after switching on, the signal transmitter (buzzer) plays back the programmed battery type (one, two, three, four or five beeps).
DPSI RV Family Operating Instructions Version 2.1 8. Error Indications DPSI systems use an internal 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. The internal resistance of the battery cells, which is indeed different for different types of batteries, thus has relatively little influence.
DPSI RV Family Operating Instructions Version 2.1 Error type 2 has the second highest priority and remains active until the DPSI 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. 3. Low voltage in Battery 1: ⎯ ⎯ ⎯ ⎯⎯⎯⎯⎯⎯⎯⎯ Error signal: 3 x 0.1 second beeps, each with a 0.
DPSI RV Family Operating Instructions Version 2.1 Hint: The limits for detecting low voltage of the algorism are designed especially for the operation of RC flight models. When the DPSI 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”). 9.
DPSI RV Family Operating Instructions Version 2.1 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 to any extremely hot or extremely cold temperatures, moisture or humidity. This would lead to danger of malfunction, damage or decreased efficiency. Use only accessories that have been approved by us in conjunction with the DPSI (e.g.
