TWIN Lite Pro RF Transmitter Module
Instruction Manual
Introduction
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 fortransmitting 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.

LED State
| Mode | Green LED | Blue RED | Red LED |

| TW | ON | ON | ON |
How to use the external RF module
STEP1: Enable RF Module
Enter the RF system menu by the touch-
screen or use the navigation encoder key.
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).
STEP2: Channel Range Setting The TWIN Lite RF module supports 24 channels
(1-8ch / 1-16ch / 1-24ch). The channel range is configurable by pressing the
channel bars, please also make sure of the channel configuration before using
the module.
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.)
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.)
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”.
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.
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.
How to bind the receiver in the ELRS mode
STEP1:
Change the binding mode to [ELRS] under the
[TW Lite] module menu.
And press [Config] to enter the binding menu.
STEP2:
Power the ELRS receiver on and off 3 times,
and the LED on the receiver will do a quick flash twice that indicating the
receiver is in the binding mode.
Click the [Bind] and if the receiver
LED keeps lit, it means the receiver is bound successfully.
Range Check
A pre-flight range check should be done before every flight, in case the signal loss is caused by the reflection of the signal by the nearby metal fence or concrete, and the shading of the signal by buildings or trees during the actual flight. Under normal circumstances, in Range Check mode, the RSSI at 150m is about 45-50.
- Place the model at least 60 cm (2 feet) above the non-metal contaminated ground (such as on a wooden bench). The receiving antenna should be in a vertical position.
- Ener the ETHOS system, move to the “RF System”, scroll the Encoder to select “RANGE” mode and press Encoder. In range check mode, the effective distance will be decreased to 1/30.
How to set Failsafe
There are 3 failsafe modes when the setting is enabled: No Pulse, Hold, and Custom mode.
- No Pulses Mode: On loss of signal, the receiver produces no pulses on any channel. To use this mode, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Hold Mode: The receiver continues to output the last positions before the signal was lost. To use this mode, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Custom Mode: Pre-set to required positions on the lost signal. Move the cursor to the failsafe mode of the channel and press Encoder, then choose the Custom mode. Move the cursor to the channel you want to set failsafe On and press Encoder. Then rotate the Encoder to set your failsafe for each channel and short-press the Encoder to finish the setting. Wait 9 seconds for the failsafe to take effect.
Note:
- If the failsafe is not set, the model will always work with the last working status before the signal is lost. That could cause potential damage.
- When the failsafe is disabled on the RF module side, the failsafe set on the receiver side will be applied.
- SBUS port does not support the failsafe setting in No Pulses mode and always outputs signal. Please set “Hold” or “Custom” mode for the SBUS port.
