5. Pin Assignment - Special Cases and Display
5.1 Wing connector port:
The wing connector port, to which the
12-pin central plug of wing wiring
harness is attached, is assigned to
Easy-Patch channels 1 to 6 and
channel 9. Channel 9 is parallel on both
wing root adapters! Both spoiler servos
can then be operated at one channel..
Additionally you can loop a Gyro into
channels 1 and 3 (see 5.3 Gyro port)
Special Case: if you use only one aileron for each wing half, you can
use channel 2 (aileron 2 left) and channel 4 (aileron 2 right) also for
the separate control of two individual spoiler Servos.
Special Case: if you use only one aileron channel for each wing half
and no gyroscope system is attached, you should use the EasyPatch channels 2 and 4 for the control of the ailerons and leave the
Jumper at its place. So you have two servo connectors for channel 1
and two connectors for channel 3 at the Gyro port for special
functions e.g. two elevator servos and/or two rudder servos.
Special Case: if your airplane also has no flaps, you additionally
have channels 5 and 6 at the left side of the main board for special
functions within the fuselage.
Special Case: if you use one aileron channel and one flap channel
for each wing half, in addition to a gyroscope system and need further
channels for special functions, you should use the Easy-Patch
channels 1 and 3 for the control of the ailerons and channels 2 and 4
for the control of the flaps. Take the two red Jumpers off and attach
the gyro to the gyro port. This allows for channels 5 and 6 at the left
side of the main board to be used for special functions within the
fuselage.
5.2 Receiver port
Only the receiver should be connected
to the receiver port on Easy-Patch.
There are 12 channels available, and
you can connect multiple receivers.
The receiver port is rated at 250mA
maximum continuous load.
Do not connect any servo
directly to the receiver!!
5.3 Gyro port
If you want to use a gyro, please
disconnect jumpers L and R. Gyro
sensitivity is adjusted via channel 7. In
all other cases you can leave the
jumpers in place but
&
5.4 Batteries
To fully exploit Easy-Patch's capability,
use two identical 5-cell battery packs.
Each battery port can handle a
maximum continuous load of 20A.
Preferably
use
high-quality,
lowresistance, high-capacity cells.
Special Case: If you want to use a tow release and an electric motor,
you may connect the motor controller, which draws very little current,
directly to the receiver. Keep in mind however, that Easy-Patch's
filters have no effect on the controller in this case. Plug the tow
release servo into channel 12 (under Servo port at connector marked
engine controller). If you don't use a gyro, it's better to connect the
tow release servo at channel 7 (gyro sensitivity) and the controller at
channel 12.
Always remember that the receiver port can handle a maximum load
of 250mA!
Special Case Should you require additional channels i.e. as for a
wheel brake or gear door actuation and don't require a gyro or two
aileron channels per wing half, you can use channels 1 (aileron 1 left),
3 (aileron 1 right), and 7 (gyro sensitivity) for various purposes.
Connect ailerons to channels 2 and 4. Channels 1, 3, and 7 at the
gyro port are now available for individual use.
- If you leave jumpers L and R in place, you have two servo
connectors as output for channel 1 and two connectors as output
for channel 3 at the Gyro port for special functions e.g. two elevator
servos and/or two rudder servos
- If you disconnect jumpers L and R, gyro port channel 1 (
5
/
@
gyro port channel 3 (
5
/
@are
input for the corresponding channels at the wing connector port.
Special Case: If you want to use just one receiver pack, solder both
battery cables to the pack in parallel: Both red cables to the Plus pole
and both black cables to the Minus pole. Always use a 5-cell pack, so
that sufficient power is maintained in case of a cell failure.
Note!! In order to obtain a minimum possible power consumption in
switched-off position (e.g. during long storage periods), switch the
module as follows into the standby mode:
1.
2.
3.
power off the internal main switch.
Pull off the plug of the external main switch.
Then switch the internal main switch into central position.
The power input of the EP12-2 ESX will be reduced and hardly
measurable.. Alternatively you can separate both receiver batteries
from the system.
5.5 external switch and
external status LED
If you need an external switch, because
your Easy-Patch power supply is not
accessible or visible from outside the
fuselage, attach an external switching
cable with status LED. Please make
sure that the plug snaps in correctly.
The blue status LED serves both, power
up control and monitoring of errors
during normal operation
Normal operation: After powering up the external status LED
should light up shortly and if both batteries work perfectly, flash three
times. After flashing EP12-2ESX is ready and will store all incidents.
Storing is indicated by a short flash every 2 seconds.
Error after powering up: If the external status LED, directly after
powering up, starts flashing fast, there is a permanent case of error
with one or with both batteries. Please check the internal status LEDs
and read 5.6 Internal status LEDs for more details.
Error during normal operation: A malfunction of the power
supply may cause a fast flashing of status LED after having started
normal operation. Please check the internal status LEDs and read 5.6
Internal status LEDs for more details.
Normal Operation after powering up:
Power up check:
1 flash
System ready:
3 flashes
Data recording:
every 2 seconds short flash
Error:
fast flashing
Action:
check internal status LEDs!
Malfunction after powering up:
Power up check:
1 flash
Malfunction during normal operation:
Normal data recording:
every 2 seconds short flash
Error:
fast flashing
Action:
check internal status LEDs!
Please, always check the internal status LEDs, if external status LED
announces an error. Only the internal status LEDs can help you to find and
eliminate a problem in your power supply.
5.6 Internal Status-LEDs
The status LEDs for the two receiver
batteries are directly behind the two
battery connectors on the Easy-Patch
module. They serve both, the monitoring
of the two receiver batteries on start-up
and storage of errors during normal
operation. Under normal conditions and
after correct initialization of the system,
all LEDs should be off.
The internal status LED have the
following importance:
Normal operation: After powering up all status LEDs should light
up shortly and if both batteries work perfectly, flash three times. After
flashing, all LEDs should be off and the system is ready for use.
From now on EP12-2ESX will store all incidents.
Error after powering up: If one of the status LEDs starts flashing
directly after powering-up or lights constantly, there is a permanent
error with a battery.
Error during normal operation: If your system already started
normal operation and a LED flashes or lights up suddenly, there
might have been a malfunction of the power supply

After correct powering up all 4 status LEDs should flash 3 times and then be in off state. From now on
all possible errors will be stored and displayed. Storing is indicated by a short flash of the external
status LED every 2 seconds
The following announcements
may occur during normal
operation:
error LED on
Battery has constantly too low voltage.
Please examine the battery
error LED of one
battery is flashing,
error LED of the
other battery is off
One battery had a temporary low
voltage condition below 5,5 Volt.
Possibly caused by a bad contact or
because of a general low output
voltage one battery is nearly empty.
Please examine the battery

batteries are
flashing
There was a temporary overload or
because of general low output voltage
both battery are nearly empty. Please
examine both batteries
wait LED is
flashing
The voltage of this battery was at least
1 Volt below the voltage of the other
battery. Possibly caused by a cell
defect in this battery or high
impedance.
5.7 LED bar graph display
The 7-digit LED voltage display indicates the output voltage with very high precision and a resolution of 0,1 V
within the range of 5.4 V and 6 V.
With output voltages above 6.0 V the highest LED always remains switched on!
With output voltages below 5.4 V the lowest LED always remains switched on!
If display is in yellow status, please check the batteries and recharge them.
Please note: Though of the high accuracy of the voltmeter, extreme temperatures can cause small deviations in
measurement. The output voltage will always be, even if internal losses of the power supply are small, a little bit
lower than the battery voltage. Therefore, please examine and recharge your batteries regularly! Always use
branded batteries with the lowest possible internal resistance.

9. Safety Issues
Easy-Patch lacks -- by design and intentionally -- a power-limiter, to exclude voltage
collapse and on-board system failure when high currents occur.
Please;
• never use pliers or similar metal tools to unplug leads from Easy Patch. This might cause a short
circuit, which could damage the receiver batteries or the Easy-Patch.
•
make sure that neither metallic parts nor carbon fiber material comes into contact with EasyPatch
•
arrange all leads in a way that they don’t come into contact with hot parts (e.g. gas-powered
engine) of the airplane and do not rub against sharp edges!
•
always make sure that the batteries are charged and in perfect condition before using! Test your
batteries regularly!
•
•
Never switch on the system during charging the receiver batteries!
•
•
protect Easy-Patch and every other electronic components against humidity, fuels, exhaust gases
and extreme temperatures!
avoid heat accumulation! Do not cover Easy Patch with heat insulating material.
pay attention to all plugs, the correct polarity and the cleanliness of all contacts, leads and other
electronic devices before taken into use!
•
Don’t use power sources, which do not correspond with the data of the manufacturers of your
remote control equipment!
•
make sure that no metallic parts lay loosely one upon the other, thereby preventing click pulses,
which can disturb your receiver!
•
•
perform range tests!
Do not open Easy-Patch, do not make changes on electronics, never repair defect modules. There
are no serviceable parts inside.
