1. Functionality
DPSI V-Match constitutes a servo V-cable
that accommodates two commercially
available servos.
As a special feature, one servo (SLAVE) is
programmable for direction, as well as
center position and end-limits. Therefore,
this servo adapts ("matches") to the main
servo (MSTR).
This is especially handy if two servos actuate on one rudder (e.g. two
servos on one aileron) and synchronism cannot be established by
mechanically means. Often, it suffices if one servo's direction can be
changed (e.g. counter rotating mounted servos for the airplane's
elevator). This too, is simply accomplished with DPSI V-Match.
Failsafe-Function:
A failsafe-function is added to its features. Both servos (MSTR and
SLAVE) remain at their current position (HOLD) when encountering an
erroneous or missing receiver signal until a valid signal is again
delivered by the receiver. A flashing red LED (at the PCB's side)
indicates this state and stays active (i.e. flashes) until power is turned
off.
Powerful Servos:
The electronically design of the DPSI V-Match allows for usage of
powerful digital servos; supply voltage ranging up to 8.4 volts. Due to
the PCB (4-layer) and the thick (0.34 mm2) connection cable, current
load is especially high.

Pulse Amplifier & HF-Suppression:
Besides pulse amplifiers, which recognize and amplify even weak
servo signals, high effective noise filters are built into the DPSI V-
Match. Therefore, ferrite cores or other noise suppression measures
can be omitted.
High Precision:
Because of the intelligent software design and a highly accurate crystal
oscillator, a resolution of more than 3000 steps is obtained. Therefore,
the DPSI V-Match is also suitable for modern remote control systems
with high servo positioning precision (number of steps).

2. Programming
There is no external programming device necessary, e.g. a PC or a
programming box for programming of the DPSI V-Match. Only a
delivered magnet serves for activation of the corresponding
programming functions. Everything else is conducted with the
transmitter and remote control equipment.
During programming, settings of the original servo (master = MSTR)
remain unchanged! Programming always refers to the slave servo
(SLAVE).
Hint:
Adjustment / programming of the slave servo is only possible within the first 10
seconds after power on. Afterwards, programming is inhibited for safety reasons!
Hint:
Before starting EACH programming, the corresponding transmitter stick (or
switch actuator) must be positioned in center position!
Hints:
If both servos MSTR and SLAVE actuate a common rudder, at least one
servo linkage must be released in order to avoid mechanical touch.
Hint:
Whenever a change e.g. of the servo center position takes place, the end-limits
should be reprogrammed as well!
Hint:
Basic adjustments in DPSI V-Match correspond to Graupner/JR equipment.
Center position is 1.50ms; end-limits are set to 100% each. Of course, all remote
control sets can be used with no limitation.

Hint:
Whenever programming takes place, the integrated red LED blinks for controlling
purposes at a rate of 0.5Hz (1s on, 1s off) at the DPSI V-Match's side.
2.1. Changing Servo Direction
When changing the direction of the servo, all
other settings remain! For reversing direction of
the servo, hold the magnet close to position
"PRG" (red dot on sticker) within the first 10
seconds after power on. Distance of the magnet can be up to 8mm.
The magnet also operates through thin fuselage sidewalls, if the DPSI
V-Match is attached to the fuselage's inner sidewall using e.g. dual
adhesive tape.
2.5 seconds after positioning the magnet, the servo makes a short
move (10% stroke). If the magnet is removed within the next 5
seconds, the servo direction is reversed and permanently stored. The
DPSI V-Match now executes a restart.

2.2. Calibrating Servo Center
Programming also starts by positioning the
magnet close to the red dot ("PRG"). The
slave servo makes a short move after 2.5
seconds (just like for servo reverse). The
magnet now is not removed, but rather remains at the "PRG" position.
The stick or switch actuator must not be moved now, i.e. it must remain
in center position. After 5 seconds, the servo makes a short move
again. Now, programming of servo center is active.
The master servo now remains centered and does not move anymore,
even if the stick is moved. With each movement of the transmitter stick
out of center, the servo position (servo center) is incremented or
decremented by one step.
If the stick remains in one end-position, steps automatically increment
or decrement after 2.5 seconds. This serves for quicker settings of the
values.
Hint:
Due to the high resolution of the DPSI V-Match, changes of the servo position
are possibly recognizable only after several steps.

Remove the magnet from its red dot position ("PRG") as soon as the
slave servo reaches the desired center position. The DPSI V-Match
now starts with the newly programmed center position of the slave
servo.
Hint:
Reprogram the end-limits in order to obtain linear curves after programming the
servo center.
2.3. Calibrating End-Limits
Start programming of end-limits just like
programming servo center. Here, the
transmitter stick (or switch actuator) is set to
maximum position (servo end-limit) within 5
seconds after the servo makes its first short move. After these 5
seconds the servo moves again shortly and both servos remain in their
actual (maximum)-position. Reposition the stick to its center position –
servo positions do not alter!

DPSI V-Match Operating Instructions Version 1.0
Page 10 of 16
Here too, the stroke of the slave servo changes by increasing or
decreasing steps when moving the stick out of its center position.
Remove the magnet when the desired end position is reached.
Hint:
Whenever changing servo settings, all values should be reprogrammed, i.e.
center and end-limits! Sequence of programming (center, end-limits) does not
really matter.
Attention:
Programmable values for end-limits could possibly be higher than the mechanical
resolution of the servo. The servo therefore could be damaged or function
incorrectly (e.g. wheel spinning) when utilizing the full range. Therefore,
approximate the limiting values carefully. An additionally connected servo tester
(e.g. using the EMCOTEC Mini Servo Tester – part number A71050) can help if
in doubt, indicating the corresponding servo position digitally.
2.4. Deleting all Programming
Total reset of all programmed settings is
possible too. Position the magnet after power
on close to the "PRG" position and hold it
there for approx. 40 seconds. After 2.5
seconds and after additional 5 seconds the servo makes its short move
(just like when programming center/end-limits). The transmitter stick
must not be moved at that time and the magnet must remain at the
"PRG" position. After 40 seconds have elapsed, all settings are deleted
and a restart of the DPSI V-Match takes place. Now, the magnet can
be removed.
Hint:
Whenever programming takes place, the integrated red LED blinks for controlling
purposes at a rate of 0.5Hz (1s on, 1s off) at the DPSI V-Match's side.

3. Additional Hints
These additional hints are valuable for the ambitious user who likes to
know more about the functions of the DPSI V-Match by explaining its
behavior under certain circumstances.
3.1. Adapting several Servos
If more than two servos need to be synchronized (e.g. three aileron
servos) two DPSI V-Match can be chained one after another. This
means: the input of the second DPSI V-Match connects to the MSTR
output of the first DPSI V-Match.
Now, a SLAVE output is available at the first DPSI V-Match, a MSTR
and a SLAVE output at the second one. Both SLAVE servos can now
be independently set up.

3.2. Changing the Model
If a programmed DPSI V-Match is to be used in an other application
(e.g. changing a model), generally all settings should be deleted (see
also "Deleting all Programming"). This is also true if a servo with a
different rotating direction is to be built in.
3.3. Sequence of Programming
When programming the slave servo, the rotating direction (if
necessary) should always be programmed first. Then center position
and end-limits follow, sequence is unimportant.
Hint:
Whenever there is a change, e.g. serve center position, the end-limits should be
programmed, too!
3.3. Limiting Tuning Range
The DPSI V-Match only allows for certain values when programming
or adjusting the slave servo. Because the slave servo is to be adapted
to the master servo, both servos should have similar base adjustments
in the first place, e.g. comparable center positions.
If the center of the master servo already is over 100% of the possible
servo stroke it does not make much sense to adjust the slave servo
even further. Therefore, only a maximum of +/-100% (referring to JR
values) of the servo center position is possible.
Adjustment of the slave servo is carried out by a so-called 3-point
curve (i.e. center, maximum value left/top, maximum value
right/bottom).

DPSI V-Match Operating Instructions Version 1.0
Page 13 of 16
The "distance" of the maximum position of a servo in respect to its
center must be at least 20%, otherwise the value is not programmable.
Range checking accompanies each programming. It is therefore not
possible to position the servo center position off limits. Malfunctions are
avoided this way (e.g. V-curve of the servo).
