Instruction Manual for FrSky ARCHER RS Receiver

Introduction

The Archer RS receiver integrates all of the advantages of the previous receiver in its class, the R-XSR. The RS supports full-range signal control with an equivalent telemetry range. Dual detachable/replaceable antennas assure optimal antenna reception and maximum range with its lightweight design thanks to the extremely tiny form factor. It features an inverted S.Port that allows for easily connecting flight controllers. Additionally, the RS can be used as a redundancy receiver along with any other FrSky ACCESS capable receiver equipped with a SBUS port. The best available signal will be used to ensure superior connectivity.

All Archer receivers are hyper-matched with the ACCESS protocol. They not only feature wireless firmware upgrades, increased range, and telemetry performance, but the RS also 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.

Overview

A diagram illustrates the FrSky ARCHER RS receiver's physical layout and dimensions. The receiver is a small rectangular component measuring approximately 11mm by 16mm. It features connection pins labeled GND (Ground), VIN (Voltage Input), S.Port, Inverted S.Port, SBUS_OUT, and SBUS_IN. A visible LED and a BUTTON are also indicated. Two detachable antennas are depicted, suggesting optimal reception capabilities.

Connection Diagram Example

A connection schematic shows the receiver's input and output ports. It illustrates a configuration where 'SBUS Out' connects to 'SBUS In', indicating a potential redundancy setup or signal routing. The diagram labels the receiver's pins as GND, VIN, S.Port, Inverted S.Port, SBUS_OUT, and SBUS_IN, along with two antenna connectors.

LED State

Registration & Automatic Binding (Smart Match ™)

Follow the steps below to finish the Registration & binding procedure:

1. Put the transmitter/transmitter module into [Reg] status.
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 LED will keep lit, and the transmitter displays [Bind successful].
6. The transmitter exits [Bind]. The GREEN LED will keep lit, and the RED LED will be off, indicating Working normally.

Note: Once the receiver is registered, the button is not needed anymore in the binding process.

How to switch the F.Port

For Taranis X-Lite Pro as an example: Select the Receiver, press the ENTER button, select the Options, and select F.Port.

Warning: [Options] setting in flight will cause the failsafe.

About OTA Function

For Taranis X-Lite Pro as an example: Go to the SD CARD 2/7, select the FW, press the enter button, select [Flash receiver OTA]. Power on the receiver, select the RX, go to the [ENTER]. Complete the flash process; the transmitter will display [Flash successful]. Re-power the receiver and wait for 3 seconds. The Green LED starts flashing, indicating the receiver works properly at the moment.

Note: Please do not perform the binding operation in the near range while the firmware upgrading is in progress.

Note: Update the firmware after the receiver gets bound.

Range Check

A pre-flight range check should be done before each flying session. Reflections from nearby metal fences, concrete buildings, or trees can cause loss of signal both during range check and during flight. Under Range Check Mode, the RF power is decreased, and the range distance is reduced to 1/30 to 1/10 of Normal Mode.

The point where the signal is completely lost is recommended as the node to complete the range test.

1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g., on a wooden bench). The receiver antenna should be in a vertical position.
2. For Taranis X-Lite Pro as an example: Turn on the transmitter and power on the receiver. Navigate to: SETUP 2/13 /Internal RF/ Module [Rng].
3. For transmitter RF module, please refer to its manual.

For more operation and instruction details, please refer to the radio manual.

Failsafe

Failsafe is a useful feature that sets a preset channel output position whenever control signal is lost for a period. Follow the steps to set Failsafe for necessary channels:

Failsafe for receivers supporting ACCESS can be set via the radio interface, supporting no pulse, hold, and custom modes for each channel.

1. For Taranis X-Lite Pro as an example: Turn on the transmitter and navigate to: MODEL SETUP/Internal RF/Failsafe.
2. Failsafe can be set on the receiver by short-pressing the F/S button while moving a certain channel position to a preset value after binding.
