1. Install two receivers on the aircraft as shown in the wiring diagram on the
next page.
2. Link the two receivers using the dual receiver feature of the transmitter.
For systems without dual receiver capability, link each receiver in turn.

◆ About telemetry system
When using the dual receiver function
・The telemetry function of the main receiver
can be used
・Sub-receiver telemetry function is not available
Other than dual receiver function
・Telemetry not available
・Set telemetry to INH (disabled)
Battery F/S Battery F/S
● For receivers that can set the battery F / S, set the battery F / S to 4.8 V
or less or OFF.
● Also, make sure that the battery F / S of the two receivers have the same
settings.
Since the output voltage from DLPH-2 is 5 V, if the battery F / S is set to
5 V or higher, the battery F / S will alway operate.
Fail-safe Fail-safe
● If a receiver error occurs, priority is given to the output of RX1 (main
receiver) for F/S data.
Thank you for purchasing the DLPH-2. Before using your new DLPH-2, please
read this manual thoroughly and use the DLPH-2 properly and safely. After read-
ing this manual, store it in a safe place.

Precautions Precautions
WARNING
Failure to follow these safety precautions may result in severe injury to yourself and others.
In order to prevent any short circuits, please observe the polarity of all
connections.
Ensure that the unit is connected properly to the receiver.
■ If the connector is disconnected during flight, it becomes inoperable.
Ensure that the unit is mounted in an area that will eliminate exposure to
fuel and water.
■ As with any electronic components, proper precautions are urged to
prolong the life and increase the performance of the unit.
Allow a slight amount of slack in the unit cables and fasten them at a
suitable location to prevent any damage from vibration during flight.
Be sure to link the two receivers with the transmitter.
■ It will not work unless the two receivers are linked. After startup, even
if the link on one side is disconnected, the other side will continue to
operate normally.
Used in a set of Futaba S.BUS / S.BUS2 systems.
Do not supply receiver power from the ESC. When using the receiver
power supply type ESC, remove the red (+) cord of the 3ch wiring from
the ESC so that the power is not supplied from the ESC.
■ Use a dedicated battery to power the receiver / servo.
Do not connect the servo and telemetry sensor directly to the receiver.
■ Large current flows through the Rx port of DLPH-2 and is damaged.
Do not connect a high voltage battery beyond the specifications of the
servo used.
■ There is a risk of explosion, fire and damage.
Do not use more than 60A for a moment.
■ Reference: Although it depends on the servo used and flight style, acro
flight with 15 HPS servos has been confirmed.
To ensure that the DLPH-2 is functioning as desired, please test
accordingly.
■ Do not fly until inspection is complete.
Before the flight, disconnect the wiring of the main receiver from the
DLPH-2 that is operating normally, and check if the sub receiver alone
can control it.
■ Check if the DLPH-2 switches.
Do not use the DLPH-2 with anything other than an R/C model.
How to Use How to Use
Do not supply receiver power from the ESC. When using the
receiver power supply type ESC, remove the red (+) cord
of the 3ch wiring from the ESC so that the power is not supplied
from the ESC.
■ Use a dedicated battery to power the receiver / servo.

Dual battery system Dual battery system
Two power supply batteries can be connected to the DLPH-2. Power is supplied
from the battery with the highest voltage. The operating time is the total time of the 2
batteries. For example, even if the voltage of one battery drops, power can be supplied
from the other battery. Even one battery can be used, but safer flight is possible if 2
batteries are used.
This receiver employs an electronic switching (current is controlled by an FET circuit)
system. When the exclusive switch is set to ON or is pulled, the power is turned on.
Switches other than the exclusive switch cannot be used. In addition, since a very
small current flows even when the power is off, always disconnect the battery from the
connector when the receiver is not in use.
One or 2 batteries can be connected. When 2 batteries are connected, the battery with
the highest voltage is used. When only one battery is connected, always insulate the
unused connector. The battery can be connected to either side.
Use batteries with sufficient capacity for the specifications and number of servo motors
to be used.
Even if the voltage of one of the E l e c t r i c p o w e r w i l l b e
automatically and alternatively
batteries drops, power is supplied
from the other battery. supplied from the battery which

The DLPH-2 is equipped with a telemetry sensor function. The receiver voltage displayed on the
transmitter home screen is only a constant value. The voltages of battery 1 and battery 2 should
be monitored by telemetry voltage.

DLPH-2 uses two continuous slots. Please note that the proper default start slot for this accessory
is number 6. When setup-changing or adding, it is the following numbers that are made to a start
slot.
1,2,3,4,5,6,8,9,10,11,12,13,14,16,17,18,19,20,21,22,24,25,26,27,28,29,30
By connecting the transmitter and SB2 port, it is possible to register to the transmitter and change
the start slot. In that case, it is necessary to connect the battery to DLPH-2 and supply power.
Information on how to change the slot assignment is included in the transmitter's manual.
