PWM/PPM/I-BUS/S.BUS/I-BUS 2 RSSI These ports connect the receiver to various models, component's and flight controllers. GND: Connect to ground wire. VCC: Power supply voltage from 3.5 9V. N.Port: In the [RX Settings] menu, select the RX port protocol, and the signal output can be set to PWM/PPM/I-BUS/S.BUS/I-BUS 2. The RSSI signal strength output is turned off by default, and the relevant settings can be made in the [Signal Output ] menu under the transmitter

[RX Setting]. Product Model: TMr RF: 2.4GHz ISM 2.4G Protocol: AFHDS 3 Antenna: Dual Antenna Input Power: 3.5-9V RSSI: Yes Data Output: PWM/PPM/I-BUS/S.BUS/I-BUS 2 Temperature Range: -10 +60 Humidity Limit: 20% 95%

Online Update: Yes Dimensions: 16*12*2mm Weight:0.9g Certification: CEFCC ID: N4ZTMR000 Binding 1. 3 2. 3. 4. 1. Press and hold the receiver BIND button while powering on the receiver ,release the BIND button after receiver is powered on or powering on the receiver first, press and hold the BIND button 3 seconds , the LED on the receiver will flash rapidly;

2. Put the transmitter into bind mode.(See the transmitter's instruction manual for more information) 3. Binding is successful when the receiver's LED stop flashing. If the transmitter is one-way transmission, manually exit the transmitter when the receiver status indicator flashes slowly, Binding is successful when the receiver's LED stop flashing. 4. Check to make sure that the transmitter and receiver are working as expected, if there are any issues or unexpected operation follow the steps above to bind again.

If after an update the transmitter is unable to connect or bind to the receiver, it is necessary to put the receiver into forced update mode. 1. Press the bind button of the receiver, and the indicator light flashes three times after power-on, or power on the receiver first, press and hold the bind button for 10 seconds and then the indicator light flashes three times and then off, release the bind button 2. On the transmitter side, select the receiver to update and enter the update state. During the update process, the LED light flashes three times and one off;

3. updating is successful when the receiver status indicator flashes slowly. Failsafe

PWMPPMi-Bus out i-Bus 2 S.BUSi-Bus2i-bus

, Compatibility The failsafe function is used to output the channel according to the out-of-

control protection value set by the user after the receiver loses its signal and is out of control to protect the model and personnel. This receiver supports three failsafe modes: "Free", "Hold", and "Fixed value";

"Free" mode refers to PWM, PPM, i-Bus out, i-Bus 2 converter entering the failsafe state keep the channel value of no output signal. The S.BUS, i-Bus2, and i-bus converters output the last received signal channel value of the transmitter. "Hold" mode means that after entering the failsafe state, keep the output of the last transmitter signal;the "Fixed value" mode means that after entering the out-of-control protection state, the set signal channel value is maintained to output the signal. AFHDS3 PL18 1.0.55 NB4 2.0.93 NB4 lite 1.0.10 3.0 The TMr receiver is compatible with all AFHDS 3 transmitters (Note: It is currently applicable to PL18 1.0.55, NB4 2.0.93 and NB4 lite 1.0.10 and later versions. The high-frequency library used by the firmware is version 3.0.) 1 Attention:

Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury. Make sure the receiver's battery is disconnected before turning off the transmitter, failure to do so may lead to unintended operation or loss of control. Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise. Keep the receiver's antenna at least 1cm away from conductive materials such as carbon or metal. Do not power on the receiver during the setup process to prevent loss of control.
