Specifications

The Twin Lite PRO is a powerful RF module which enables ETHOS capable radios to bind to the TW series 

receivers and support the TW protocol’s dual 2.4G frequencies simultaneously on the same receiver. 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 module, and receiver at the same time.

The RF module has two 2.4G external antennas RF mounted to provide multi-directional and wider coverage for 

transmitting signals compared to a single antenna design. Taking advantage of these features, the Twin system 

can provide less latency and higher reliability at a faster data rate with confidence.

In addition to the TW mode, this module also supports ACCST D16, ACCESS, and ELRS 2.4G modes, this 

means users can benefit from a wide range of compatible receiver options to choose and bind to when building 

the RC model. The Twin Lite Pro module offers resilient RF power options up to 500mW, constructed with the 

CNC machined metal module shell that helps aid heat dissipation, this system can ensure a stable long-range 

control further around tens of kilometers under long working hours.

STEP5: Automatic Binding (Smart Match)

Move  the  cursor  to  RX1  [BIND],  press  it  and  

repower the receiver.

Click  the  RX  to  complete  the  binding  after  the 

receiver window pops up, the system will confirm 

"Bind succeed". 

STEP3: Model ID Setting

The system assigns the receiver a number for the 

receiver (Model ID) automatically while creating a 

new model. ( The Model ID can be set from 00 to 

63, with the default ID being 1.)

STEP1: Enable RF Module

Enter the RF system menu by the touch-screen or 

use the navigation encoder key. 

How to use the external RF module

Choose the External Module.

Then turn the state of External RF to On. Set the 

binding  mode  for  the  external  RF  module 

corresponding  to  the  receiver  (ACCST  D16, 

ACCESS, ELRS, TW MODE).

STEP6: RF Power Setting

TWIN Lite Pro can offer multiple RF power options 

up  to  500mW  which  can  achieve  a  further 

controlling range. 

Open the Power menu bar and select the desired 

power level according to usage.

STEP1: 

Change  the  binding  mode  to  [ELRS]  under  the 

[TW Lite] module menu.

A

nd press [Config] to enter the binding menu.

How to bind the receiver in the ELRS mode

STEP4: Registration

For  TW  Mode  as  an  example,  select  the  Set 

[Register]  for  getting  the  radio  into  Registration 

status  in  the  RF  System-External  Module  tool, 

then  press  the  F/S  button  on  the  receiver  and 

power the receiver on.

When the "RX Connected" page pops up, press 

the  [REGISTER]  to  complete  the  Registration 

procedure and then power the receiver off.

(The system automatically assigns the receiver a 

UID differently in the same model when you have 

several receivers to bind at the same time.)

Reset: Registration procedure is not  required

to repeat anymore after the receiver was 

once registered even though the receiver is 

deleted. Pressing the [Reset] and repower 

the receiver can have the bound recovered.
