DLPH-1 Dual RX Link Power Hub Instruction Manual
*If the battery level is 40 – 30% or less, the receiver will not turn on for safety.
Receiver Link
- Install two receivers on the aircraft as shown in the wiring diagram on the next page.
- 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 the dual receiver function
- Telemetry not available
- Set telemetry to INH (disabled)
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 DLPI-I-1 is 5 V, if the battery F / S is set to 5 V or higher, the battery F / S will always operate.
Thank you for purchasing the DLPH-1. Before using your new DLPH-1, please read
this manual thoroughly and use the DLPH-1 properly and safely. After reading
this manual, store it in a safe place.

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 component, 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 5. 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.
■ A large current flows through the Rx port of DLPH-1 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. O 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-1 is functioning as desired, please test accordingly.
■ Do not fly until the inspection is complete.
Before the flight, disconnect the wiring of the main receiver from the DLPH-1
that is operating normally, and check if the sub receiver alone can control
it.
■ Check if the DLPH-1 switches.
Do not use the DLPH-1 with anything other than an R/C model.
How to Use Wiring
Dual battery system
Two power supply batteries can be connected to the DLP1. 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 a safer flight is possible if 2 batteries are used.
This receiver employs an electronic switching (current is controlled by a 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 batteries drops, power is supplied from the
other battery.
Even if the power supply wiring of one of the batteries breaks, power is
supplied from the other battery.
When the switch is set to ON, power is supplied from the battery with the
highest voltage. The operating time is the total time of the 2 batteries.
Electric power will be automatically and alternatively supplied from the
battery whose voltage is higher.
Battery LED
The battery LED on the side being used lights up. It turns off when each becomes 6 V or less.
Telemetry function (voltage display)
The DLPH-1 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 I and battery 2 should be monitored by telemetry voltage.
DLPH-1 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-1 and supply power. Information on how to change
the slot assignment is included in the transmitter’s manual.
