TW MX Receiver
Instruction Manual

Introduction

TWIN series TW MX receiver features a new stable TW protocol which benefits from simultaneously integrating dual active 2.4G frequency bands. The TW active-active  protocol is different from the general active-standby redundancy solutions (where one receiver takes over signal control only when the other is in Failsafe mode), with the TW  protocol, dual 2.4G frequency bands are active on the TW series receiver at the same time.
This receiver is designed for rc users who want to benefit from resilience and long range in their radio communications, typically tens of kilometers is achievable. The TW  MX receiver is light weight and its smaller size occupies less space which makes it very suitable for users who have constraints with limited installation space and weight.
As a micro receiver, the TW MX receiver is equipped with 2x 2.4G antennas. The signal output ports include one SBUS output channel and 4 PWM output channel ports.  TW MX receiver also supports telemetry functions through FBUS / S.Port. By setting the TW MX to use FBUS protocol in the ETHOS system, the signal control and telemetry can be connected to any device that supports FBUS protocol through only one line to achieve bidirectional transmission, also simplifying the model build using  fewer wires.
In addition, TW MX also supports 4ms race mode with ultra-low latency. When combining race mode with TW series resilient dual 2.4G solution, racers have a fast, stable,  and reliable signal in racing competitions, without fear of signal loss due to interference.

Registration & Automatic Binding

Follow the step below to finish the registration & binding procedure:

1. For TWIN X Lite as an example, enter into the Model, select RF System, turn on the internal module, select status [ON] and TW MODE(Type), 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 into 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. Power off the receiver.
5. Move the cursor to select any one of the 3 receivers and press [Bind].
6. Connect the battery to the receiver.
7. Select the RX, the GREEN and BLUE LED will keep lit, then the transmitter displays [Bind successful].

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

LED State

Status| Green LED| Blue LED| Red LED
LoRa| –| On| Off

Failsafe| Off| Off| On

How to switch the S.Port/F.Port/FBUS
Enter into the Set-Options, click the Telem.Port, and select S.Port/F.Port/FBUS.
How to switch SBUS channel mode
Enter into RX Settings, click [SBUS], then select SBUS-16 mode or SBUS-24 mode.
How to enter into 4ms race mode
Enter into Model-RF system, select the Channel Range as CH1-CH8. Click [Switch Positions] and select a switch to start 4ms race mode.

About OTA function
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).

Instruction Manual for FrSky TW MX Receiver

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to  provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate transmitter frequency energy and, if  not installed and used in accordance with the instructions, may cause harmful interference to transmitter communications. However, there is no guarantee that interference will  not occur in a particular installation. If this equipment does cause harmful interference to transmitter or television reception, which can be determined by turning the  equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced transmitter/TV technician for help.
