FrSky ARCHER SR8 PRO Instruction Manual

Instruction Manual for FrSky ARCHER SR8 PRO Receiver
Introduction
The Archer SR8 PRO are gyro-stabilized receivers with a built-in 3-axis gyroscope and 3-axis accelerometer, they have 8
high-precision PWM channel outputs and features multiple flight modes and configuration methods. They support full-range signal
strength with dual detachable antennas it guarantees optimal antenna-reception and maximum range. In addition to all this, the SR8
PRO can also be used as a redundancy receiver along with any other FrSky ACCESS capable receiver equipped with an SBUS port.
All of the Archer receivers are hyper-matched with the ACCESS protocol. They not only feature wireless firmware upgrades and
increased range and telemetry performance, the SR8 PRO now supports more functions like configurable telemetry power,
S.Port/F.Port switching and FLR output. Additional valuable features are under development to unlock the true potential of the ACCESS
protocol.

Gyro gain adjustment of CH9: When the the value of CH9 is in the center, the gain is zero. The gain increases as the value gets bigger.
Until the value is ±100%, the gain reaches maximum.

When Delta wing/Flying wing/V-tail is selected, the signal produced by the transmitter should be without active mixes on the channels
related to AIL and ELE. SR8 PRO will mix the AIL(CH1) and ELE(CH2) input signal with a fixed mix percentage automatically. Signals
on CH4~CH8 will behave as required by the user.
M: represents a neutral signal period (1500μs)
H: represents the time of required signal change to activate the mode (50μs). When the factory settings are selected, the switch position
shown above represents the required modes.
Flight mode:
Off:
When the mode is activated, SR8 PRO will transmit the received commands produced by the transmitter to the model without
compensating.
Stabilization: When the model is activated, SR8 PRO will compensate with external forces (wind) as soon as receiving commands
from the transmitter. This function is used to enhance the stability of the model on three axes (Pitch, Roll, Roll). CH9 could be used to
adjust gyro gain by assigning a knob or a slider, changing the sensitivity of the counteracting signal produced by the internal three-asis
gyroscope.
Automatic level: When the mode is activated, SR8 PRO will make the model return to level orientation with internal three-axis
accelerometer and three-axis gyroscope on AIL and ELE channels after the sticks being released to neutral. RUD channel works in
stabilization mode only.

Note: CH9~CH12 are not marked on the diagram.
CH9 Edit — Setting CH9 at Weight 50 and offsetting 50, the assigned pot/slider will work normally.
Attentions
CH1~CH8 should be connected to the corresponding servos.
S.Port could be used to update, edit parameter settings via FrSky STK PC tool and connect with telemetry sensors.
Registration & Automatic binding (Smart Match )
Follow the step below to finish the Registration & binding procedure:
1. Put the transmitter/transmitter module into [Reg] status.
1.1 For Taranis X-Lite Pro as an example, turn on the transmitter, go to the MENU-MODEL SETUP-PAGE 2,choose Internal or External
RF, and select [Reg].
2. Connect the battery to the receiver while holding the button on the receiver. The RED LED and GREEN LED on the receiver will be
on, indicating into the [Reg] status. Select [ENTER] on the transmitter, The RED LED and GREEN LED on the receiver will flash, and
the transmitter displays [Registration ok].
3. Turn off the receiver.
4. Move the cursor to select the receiver 1 [Bind].
5. Connect the battery to the receiver, the GREEN LED will flash, indicating into the [Bind] status. Select the RX, the GREEN will keep
lit, and the transmitter displays [Bind successful].
6. The transmitter exit [Bind], GREEN LED will keep lit, RED LED will be off, indicating Working normally.
Note: Once the receiver is registered, the button is not needed anymore in the binding process.

Set up your model and receiver
You need complete calibration of Accelerometer about the six positions via the STAB RX.Lua/FreeLink APP/FreeLink.exe firstly.
Step1: Connect your servos follow the channel list according to your model.
Step2: Set you radio follow the channel list.
Step3: Choose the Wing Type via the configuration tool (STAB RX.Lua/FreeLink APP/FreeLink.exe).
Step4: Choose the AUTO LEVEL mode, check the model servo feedback.
Step5: Choose the manual mode, check servo feedback via transmitter.
Quick Mode
It supports stabilization mode and manual (six-axis off) mode and configured through CH10. What's more, an urgent mode is added to
configure automatic level mode default through CH12. The precise configuration is written below.

CH12 SW Down
Note: The default mode of SR8 PRO is Quick Mode. When re-flashing firmware of SR8 PRO or replacing with a new one,
the preset mode will be cleared out.
- If Quick mode is applied, there is no Knife Edge or (3D) Hover mode.
- CH11 is not used when using Quick Mode.
Modes
Conventional Model
The model types could be enabled via STAB RX.Lua/FreeLink APP/FreeLink.exe). If required, SR8 PRO could be used as a standard 8
channel receiver.

Hover: When the mode is activated, SR8 PRO will make the nose of the model straight up with internal three-axis accelerometer and
three-axis gyroscope on RUD and ELE channels (ELE and RUD inputs are not required). Under this mode, AIL is used to control the
rotation of the model and THR adjust the altitude. AIL channel works in stabilization mode only.
Knife-egde mode:
accelerometer and three-axis gyroscope on RUD and AIL channels.Thus, AIL inputs are not required. While the mode steering is done
with ELE, altitude will be maintained with THR/RUD. ELE channel operates in stabilization mode only.
Configuration
Methods: APP configuration
FrSky radio configuration
PC configuration software (FrSky STK usb updater)
Configuration parameters: Wing type, mounting type, gain setting, offset angle setting, accelerometer calibration.
Off
APP(IOS/Android) configuration：
• Connect the SR8 PRO to the App with AirLink S.
