FrSky TD R18 2.4G 900M Tandem Dual Band Receiver Instruction Manual

FrSky TD R18 2.4G 900M Tandem Dual Band Receiver Instruction Manual

Introduction

Neither like other FrSky 2.4G receivers nor 900M receivers, the Tandem dual- band series receivers work simultaneously at both 900M and 2.4G frequencies that means it can give not only low latency signal control but long control range with an enhanced level of high reliability and anti-interference performance.

The Tandem series receivers adopt the triple antenna design that can give the multi-directional coverage as wide as possible for the remote signal. The 900M antenna comes with a newly designed small form factor, but it has the equivalent high-performance as the original 900M antenna.

The data (Power & Signal related) under unusual status during the flight can be recorded by Tandem receivers through a built-in black box module. TD R18 also provides a socket that can be used to connect the switch panel to enable the built-in Power Switch function.

The configurable 18 channel ports are a big feature of TD R18, each channel port can be assigned as PWM, SBUS, FBUS, or S.Port. With the FBUS protocol, the Tandem series receivers can open up the possibility of seamlessly pairing with multiple telemetry devices (Neuron ESC, Advance Sensors, etc.) as well as simplifying the builds setup.

Note: If a sensor is connected to the master receiver, please turn off the telemetry of the slave receiver when using the redundancy function, to ensure the transmission of sensor data.

Registration & Automatic binding

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

1. For TANDEM X20 as an example, enter into the Model, select RF System, turn on the internal module, select status [ON] and TD MODE(Type). You can select the Internal / External antenna and the power as you need, then select [Register].
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 the [Reg] status.
3. When it shows the Register ID, RX name, and UID, click [Register]. The RED LED and GREEN LED on the receiver will flash, and the transmitter displays [Registration OK ].
4. Turn off the receiver.
5. Move the cursor to select any one of the 3 receivers [Bind].
6. Connect the battery to the receiver.
7. Select the RX, the GREEN will keep lit, and the BLUE will flash. Then the transmitter displays [Bind successful].

LED state

How to configure channel ports

1. For TANDEM X20 as an example, please select RF System, click [RX1 TD18R]-[Set]-[Options].
2. You will enter into RX Settings,then function definition of every single pin (pin1-pin18) could be set.
   – pin1: Smart Port/ SBUS OUT/ FBUS/ SBUS In/ PWM
   – pin2-18: Smart Port/ SBUS OUT/ FBUS/ PWM

How to enter into the Race mode (down to 4ms)

Enter into Model-RF system, select the Channel Range as CH1-CH8. Click [Switch Positions] and select a switch to start the race mode.

Black Box

Black box records flight data, e.g, RX Reset Case, RSSI, VFR and so on.
For TANDEM X20 as an example, to get flight data, please go to RF System-[Set]-[Flight Data Record].

About OTA function

For TANDEM X20 as an example, go to the [File manager], and select the FW, press the enter button, select [Flash RX by int.OTA]. Power on the receiver, select the RX, go to the [ENTER], complete the flash process, the transmitter will display [Success]. Wait for 3 seconds, the receiver works properly at the moment.

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

Note: Update the firmware after the receiver getting registered (OTA).

Failsafe

Failsafe is a useful feature which is for a preset channel output position whenever control signal is lost for a period.
Follow the steps to set Failsafe for channels necessary:
Failsafe for receiver supporting ACCESS can be set via transmitter interface, which support no pulse, hold and custom three modes for each channel.
For TANDEM X20 as an example, turn on the transmitter, go to: MODEL SETUP/Internal RF/Failsafe.

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 the flight. Under Range Check Mode, the RF power would decrease and Range distance will reduce to 1/30–1/10 that of Normal Model.
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 vertical position.
Much more operation and instruction please refer to transmitter manual.
