GND=These 3 GND pins are all common ground.
VCC=transmitter power supply input (support 2s-6s, 3s recommended)
P/S=PPM or SBUS signal input (PPM and SBUS signal will be
identified automatically)
5V=5Voutput (power supply receiver)
1=Channel 1 PWM input (if PPM2 was turn on then PPM2
input via this pin)
2=Channel 2 PMW input
3=Channel 3 PMW input
4=Channel 4 PMW input

TX/5=Channel 5 PMW input (when upgrading connect USB to TT
L ’s RX)
RX/6=Channel 6 PMW input (when upgrading connect USB to TT
L ’s TX)
7==Channel 7 PMW input
8==Channel 8 PMW input
Ground wire=These 10 GND pins are all common ground on receiver.
5V=Receiver 5V power supply input (support 3.3v-8v power suppl
y, 5v recommended)
Channel 1=Channel 1 PWM output
Channel 2=Channel 2 PWM output
Channel 3=Channel 3 PWM output
Channel 4=Channel 4 PWM output
Channel 5=Channel 5 PWM output

Channel 6=Channel 6 PWM output
Channel 7=Channel 7 PWM output
Channel 8=Channel 8 PWM output
Channel 9=RSSI output (Capable to set output mode)
Channel 10=PPM output (Capable to set output mode)
Above each pin’s function was defaulted by receiver, which is capa
ble to reset to change its function, For example , set the channel
10 to SBUS output, details of setting process please refer the functi
on diagram.
Note :To keep the 433 signal on the best condition, we recommend
setting the transmitter and receiver’s antenna vertical to the ground
,the receiver’s antenna can be set up by using a plastic beverage
straw or a chopstick (Do not using the carbon stick or any metal r
elated sticks)
Setting process of common used function
Note: Before frequency binding or setting fail-safe transmitter must
be accessed in one of PPM,PWM or SBUS signal successfully.
(1) Single receiver’s frequency binding process: keep press receiver’s
button until blue light flashing release it, then power supply to rec
eiver (when transmitter’s blue light stop flashing, receiver’s red lig
ht on, frequency binding success )

5
(2) Lost control protection setting process: Set all the channel of re
mote controller to the position where the receiver was expected to
output the proper signal during the lost control condition, then keep
press the button until the red light start flashing to release it,
power supply to the receiver(transmitter’s red light stop flashing
and receiver’s red light on means set success, Note:before set lost
control protection the frequency binding must be finished successfull
y )
(3) Multiple receivers frequency binding process: Follow the “(1)Sin
gle receiver’s frequency binding process” binding the first receiver’s
frequency. The second one or more than two receivers please refer
following process.
Keep press the transmitter’s button until purple light flashing rel
ease it, then power supply to receiver (when transmitter’s purple lig
ht stop flashing ,frequency binding success )
Transmitter restore to default setting: keep click the button
9 times and wait for instruction, once red light rapidly flashing pr
ess button 1s more, release the button after the red light and blue l
ight start flashing alternately , restore success.
DALRC 433Mhz Transmitter Setup

Continuously click the button on the Transmitter “N” times on
standby mode condition system will enter into the corresponding f
unction setting.
•For example: we want to set the transmitting power to (1500mW)
1.5W, only need to click the function button 3 times, then flashes 3 times
purple light (the purple light flashing times are same with the times you
click the button) after that, coming to red light or blue light flashing (if
the blue light intermittent flashed 4 times that mean the current power is
1000mW(1wM)), when need to change the power just click the function
button which will switch to next step setting, intermittent flashed 5 times
red light means 1500mW), by this time in order to save the current setting
you need to press the function button 1s more, red light and blue light
alternately flash 2 times means saving success, automatically restart.
After function 5-8 set finished, transmitter need to reenter
frequency binding mode,(transmitter needs transfer the set parameter to
receiver), then power supply to receiver will finish frequency binding .
(all the setting will be saved permanently unless Restore factory setting or
reset it deliberately) the following is function diagram.

Transmitter enter into upgrade mode setting : connecting the
upgrade module with transmitter, keep press the setting button, connect
power, release the button after transmitter indicator light rapidly flashing
in red with blue and to enter in upgrade mode, connect with computer
afterwards.
Receiver enter into upgrade mode setting: connecting the
upgrade module with receiver , linked channel 7 and channel 8 ‘s signal
wire,plug in computer to enter in upgrade mode, then cancel the linking
between channel 7 and channel 8.
Software operation: While plug in QUHF device, after select
the correct COM from COM Port ,QUHF device will connected
automatically (check the COM Port from the device manager), then
select the firmware from the choice box which is below the software and
click start upgrade firmware ,after upgrading finished QUHF will restart,
pull out the upgrade module.
