The DPSI RV Mini 5 corresponds to pilots of the 2m to 2.7m air acrobatic class who need up to 10 servos and where up to 2 servos actuate one rudder. Therefore, only heavy loaded rudders are supplied by the DPSI (aileron, elevator and yaw rudder). Servos for additional functions (e.g. engine, retractable landing gear, etc.) are connected directly to the receiver.

The DPSI RV Mini 6 is mainly used by jet- and glider-pilots (as well as engine driven planes and helicopters) were more channels are necessary but only one
powerful servo actuates one rudder. Here too, additional (less powered) servos can be directly supplied by the receiver.
Examples for the DPSI RV Mini 5 (Magic)
An acrobatic airplane with 2 servos per aileron and 2 servos for the yaw rudder. The throttle servo is directly connected to the receiver.

In these examples, the outputs of the DPSI RV Mini are assigned to the corresponding rudders. Outputs at the DPSI are labeled "Out 1/1", "Out2", and so on.
Additional servos and auxiliaries can be directly connected to the receiver.
Hint:
Assignment of the receiver channels to the DPSI is totally arbitrary and therefore not stringent. Mapping according to the manufacturer (e.g. channel 1 = throttle, etc.) is not necessary. Receiver channel 3 can be connected to DPSI input 1 just as well. Any combination is allowed and possible.

5.1. Dual Current Supply
First of all the DPSI RV Mini is a dual current supply with regulated output voltage which allows for usage of all commercially available batteries as a receiver power supply (NiCd, NiMH, LiIon, LiPo, LiFePo, etc.).
It's a dual current supply because two batteries can be connected to the system. If one battery fails, secure operation is guaranteed by the second battery. Normally, both batteries are discharged equally at the same time. Additionally, current drawn from each battery is cut in half due to the two batteries connected in "parallel" which allows for batteries with lower current load capabilities.
5.2. Electronically Switches
The batteries are switched using fail-proof electronically switches. The external switch actuator only generates the On/Off signal. Power is switched by highly loadable semiconductors. Thanks to the electronically switches there is no power loss, contacting problems or transition resistance. All DPSI RV Mini systems are built with separate electronically switches, i.e. all electronics are dual. The switches are fail-proof and are controlled by a self holding circuitry (not by means of a microcontroller!).
An operating DPSI RV Mini stays turned on even if the On/Off switch actuator is removed or broken or should the microcontroller malfunction.

5.3. Detached Voltage Regulators
Until now, the receiver set was supplied directly by the connected battery (or corresponding battery switch). The output voltage of batteries depends heavily on the actual discharging state. Because 5­cell NiCd or NiMH batteries are utilized more often for optimal servo power, a fully charged battery reaches voltages up to 7.5V after turning the charger off. Although this peak voltage usually drops quickly it can shorten the life cycle of servos in adverse cases because servos usually are approved only for 6V by the manufacturer. Due to increased usage of light weight Lithium Polymer batteries voltage regulation is mandatory because these batteries carry a nominal voltage of 7.4V.
The electronics in the DPSI RV Mini make sure that the voltage is reduced to a permissible value, independent of the higher input voltage of the battery. Jumper (small pluggable bridges) allow for selection of the desired output voltage. This way, the power requirements can be adapted to the pilot needs and technical data of the servos.
As a specialty, two separate voltage regulators are built into the DPSI RV Mini each having its own selectable output voltage. Servos directly connected to the DPSI are supplied by their own voltage regulator. Its output voltage is either 5.9V or battery voltage. This means: the servos are supplied either with a regulated 5.9V (regular permissible voltage) or directly with the (unregulated) battery voltage. Later is about 7.4V for 2-cell LiPo batteries. Some servos can be supplied with this higher voltage already.
A receiver connected to the DPSI RV Mini is supplied by its own voltage regulator. This is very advantageous and gains safety significantly.
The output voltage of the receiver can be set between 5.2V and 5.9V. Besides direct connections of high power servos the concept of the DPSI RV Mini allows for connection of additional low power servos to the receiver (e.g. a throttle servo), where 5.2V normally suffice.
Page 14 of 54
DPSI RV Mini Family Operating Instructions Version 1.0
Even fast tail rotor servos or gyro systems which only "allow for" small voltages can be supplied by the receiver with 5.2V. Additionally, the receiver supply is protected against voltage peaks. This means: all disturbing pulses induced into the supply voltage are limited to safe values.
5.4. Servo Current Distribution
Furthermore, a DPSI RV Mini provides current distribution for high power servos, in order not to connect these to the sensitive receiver. All servos directly connected to the DPSI RV Mini are supplied with full power and each individual servo gets its maximum possible current. This can be recognized by a significantly better servo actuating force.
5.5. APP (Advanced Push Pull Servo Pulse Amplification)
In order to provide each servo optimally conditioned control signals from the receiver, these signals are electronically amplified. This is especially important if receivers operate on low voltage (e.g. 2.7V); their pulse amplitude is too low for some servos.
Each individual servo output of the DPSI RV Mini has its own pulse amplifier and specific HF suppression. The amplifiers recognize even very weak servo signals from the receiver and elevate the level up to an exactly defined value. They are short-circuiting proof and are supplied with their own voltage regulator for safety reasons (i.e. not with the regular servo voltage). Therefore, the signals always carry a defined and constant level over the total operating range.
An additional advantage is the current-saving APP-Technology. The amplifiers consist of special output stages which actively control the low- as well as the high-phase of the servo signal. In connection with highly effective filters which practically eliminate induced disturbances caused by long servo cables completely, best pulse quality and highest possible safety is guarantied.

DPSI RV Mini Family Operating Instructions Version 1.0
5.6. HFIB (High Frequency Interference Blocking)
In order to even increase safety, a highly effective filter is looped in into each servo's signal path. Disturbances, "caught" by long servo cables are almost completely eliminated directly at the servo connector and therefore do not reach the receiver. Ferrite cores, as often utilized, can be omitted, which saves weight and cost. The filters in the DPSI RV Mini are tremendously more effective than cheap ferrite cores; their effectiveness is controversial anyway.
5.7. Built-in V-Cable
Depending on the system (Mini 5 or Mini 6) V-cables are built in to the DPSI. This means, two servos can be connected to one receiver output. This is especially handy, if two servos actuate one rudder (e.g. the aileron of a larger acrobatic plane). The DPSI RV Mini 5 has three, the Mini 6 one built-in V-cable (e.g. for the yaw
rudder and nose gear).
5.8. Servo-Matching ("Magic" option only)
DPSI RV Mini with "MAGIC" option allow for setting the servos which are connected to V-cables arbitrarily, i.e. direction, center- and end­limit positions.
This means: one receiver channel serves actually two servos; their direction, center position and end positions can be aligned. A split elevator rudder can be controlled by one servo on each side with one single receiver channel. Therefore one receiver channel and one mixer in the transmitter get freed up.
The same holds true for controlling the yaw
rudder with coupled nose
gear. Here too, "matching" helps to adapt both servos and saves one channel.
There is no external programming device (e.g. a PC) necessary for programming or adapting the servos. A delivered magnet initiates programming.

DPSI RV Mini Family Operating Instructions Version 1.0
Each matching system has its own microcontroller (there are three in the DPSI RV Mini 5 Magic, one in the DPSI RV Mini 6 Magic). Resolution (precision) is more than 3000 steps and the delay of the servo signals is only 1500 micro-seconds!
6. Error Detection and Indication
6.1. IVM (Intelligent Voltage Monitoring)
An internal microcontroller monitors all voltages using an intelligent algorithm and indicates different errors (overload, low voltage, voltage errors, battery malfunctions) acoustically by means of a built-in piezo­buzzer. Furthermore, errors are visualized by blink codes by a LED in the switch actuator.
Additionally, the DPSI RV Mini allows for connection of external LED- Displays (battery monitors) directly at the switch actuator.
In order for the DPSI RV Mini to detect low voltages correctly the battery type must be programmed once. Simple programming allows for selection of 6 different battery types.
