1.3 R16F Introduction

1.3.1 Features of R16F

T16D transmitter comes with a R16F, 16 channels receiver, with model voltage telemetry supported. 2.4G FHSS spread spectrum algorithm and 67-channel pseudo-random frequency hopping make the R16F get excellent anti-interference performance. R16F supports three signal outputs: PWM, SBUS and CRSF.

Note: Please do the following safety check before operating your model:

RSSI test (Received Signal Strength Indicator). For test method, please refer to the manual Chapter 1.3.7 RSSI Testing.

Antenna inspection: The gray line on R16F is coaxial cable, while the transparent line with a length of about 4-5 centimeters at the top is antenna. If the transparent line is broken or damaged, it will directly affect the control distance. If any abnormality is found, please replace the receiver antenna in time.

1.3.2 Binding

T16D and R16F have finished binding by default. Turn on T16D and R16F. The signal tower will show on the top of the screen as the picture on the right, which means the transmitter and receiver has finished binding.

But if you buy a new R16F receiver for your T16D. You need to bind the receiver to the transmitter. Each receiver has an individual ID code and must bind with transmitter before using. When the binding is done, the ID code will be stored in the transmitter and there's no need to rebind.

Binding steps:

Put the transmitter and the receiver close to each other (about 60 centimeters). Note: The close distance of the transmitter and receiver may cause signal block, which leads to unsuccessful binding or signal loss.

Turn on the transmitter and the receiver, and the LED of R16F will start flashing slowly.

There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second and release, the LED will flash quickly, indicate binding process is ongoing.

When the LED stops flashing and is always on, binding is complete and there will be a signal tower shown on top of the LCD screen of the transmitter. If not succeed, the LED will keep flashing slowly to notify, repeat the above steps.

T16D and R16F binding tutorial: https://www.youtube.com/watch?v=k-TGPy9AsNU

1.3.3 Receiver Connection

Connect Cable

Picture 1 Picture 2

The connection wire for the receiver is shown in the picture above. The common ones are white/red/black wire (Picture 1) or yellow/red/brown wire (Picture 2). The two types of servo cables both are light-colored wire as the signal wire, and dark-colored wire as the ground wire, and the middle is 5V power supply, and the three wires correspond to " ".

Note: RadioLink receivers are all designed with anti-polarity connect protection. When the receiver is powered by a separate battery, the receiver will not be damaged if the battery polarity is reversed, but if the servo is connected at this time, it will damage the servo.

Model Battery Telemetry connection

R16F supports telemetry of model battery voltage, receiver voltage and RSSI. Connect one end of the telemetry cable to the R16F telemetry port, and the other end to the ESC to return the power battery voltage. Please refer to the below picture for connection of the telemetry cable:

Attention:

Reverse polarity protection circuit design for all 16 channels of R16F ensures vital components are protected from a reverse polarity connection. But the JST connector which packed with R16F for connect to battery cannot reverse polarity connect, or it will lead to the wrong voltage value telemetry.

Ext port is only used to model voltage telemetry. It can not be used to power the receiver.

1.3.4 Working Modes

R16F supports three signal outputs: PWM, SBUS and CRSF. It has four working modes in total.

R16F working modes setting:

Turning on/off the SBUS: Short press the binding button once to turn on/off the SBUS. Blue LED indicates the SBUS is turned on, and channel 16 outputs SBUS signal.

Turning on/off the CRSF: Short press the binding button twice within 2 seconds to turn on/off the CRSF. Green LED indicates the CRSF is turned on. Channel 14 receives RX and channel 15 outputs TX.

Introduction of the four working modes:

1.3.6 Installment of Receiver Antenna

It is important to install the receiver antenna correctly on the model, because wrong receiver antenna installation will cause poor signal quality.

How receiver antenna installation affects signal quality? Here are the common mistakes when installing the antennas:

The two antennas of the receiver CANNOT overlap, because they will interfere with each other. Keep the two antennas at a 90-degree angles. (As shown on the right)

Antennas should NOT be placed near metal objects, because reflection of the conductor panel will drastically worsen the signal.

Do NOT keep antennas parallel to the ground. It should be placed vertically to the ground.

Big models may contain metal parts that influence signal emission. In this case. antennas should be positioned at both sides of the model to ensure the best signal status in all circumstances.

Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no over bending.

Keep antennas away from motor, ESC or other possible interference sources.

Sponge or foam material is advised to use to prevent vibration when installing receiver.

Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration and high temperature.

Special vibration-proof material for R/C like foam or rubber cloth is used to pack to protect receiver. Keeping the receiver in a well sealed plastic bag can avoid humidity and dust, which would possibly make the receiver out of control.

Refer to the following link to view the guide on antenna installation of R16F:

https://www.radiolink.com/newsinfo/886600.html

1.3.7 RSSI Testing

If the control distance is short, please refer to this instruction to test the transmitter. This instruction will introduce the test procedure of the transmitter RSSI value and the solution to the abnormal RSSI value.

Turn on the transmitter and power on the receiver at the same time, and then the transmitter and receiver will be connected (if not connected, you need to bind again). The signal tower appears on the transmitter interface, indicating that the binding is successful. The value of RSSI will appears on the home page, and the RSSI value will keep changing according to the distance between the transmitter and the receiver. (As shown on the right)

Make the receiver antenna and transmitter antenna parallel. Keep transmitter apart from receiver about 60 centimeters and both antennas straight. It is normal that RSSI value is within the range of 0 to -30dBm. The closer the value is to 0, the stronger the signal is. (As shown below)

Abnormal signal strength solution:

Check whether the antennas of the receiver and transmitter are damaged. Most signal strength degradation is caused by antenna damage. If it is damaged, the antenna needs to be replaced. If there is no damage, you can test the transmitter and receiver for malfunctions by replacing the receiver. If still cannot solve the problem, email to after_service@radiolink.com.cn to get support.

Chapter 2 General Settings

Note:

Note: Short press End button on the main interface of T16D to quickly view channel monitor.

2.2 REVERSE

You can perform the reverse processing of the output data of one channel or more channels. This function is used in the debugging of a model.

Models may follow different standards in the design. In the assembly and debugging of a model, if you find that the operation model is opposite to the required direction, for example, the model goes to the left when you want the right direction, the output signal direction of the transmitter needs to be adjusted at this time. The function is used to adjust the action direction of output signals of each channel.

Move the cursor to the channel that needs to be modified, and short press Push button to switch the direction.

2.3 END POINTS

Adjust the travel amount of the servo output. This function is used in debug. This function can be used to set the travel amount of the HIGH, LOW and SUBTRIM at both ends of the channel respectively.

When the model is designed, there are changes in the size of the structure and the specification may not be unified. In addition, there may be different sizes of operator's habitual actions. The servo travel function can be used to set the travel amount required for each channel to adjust the corresponding structure for the best match, to obtain the required operation effect. For example, you want to operate that the turning action is not so large, you can adjust the value of the direction channel at both ends to be smaller. In this way, the turning action should be smaller, with less likely to be tailspin.

Move the cursor to the end point value that needs to be set, and rotate Push button to set the appropriate value. The end point can be set from 0 to 120.

2.4 CH SPEED

CH SPEED (channel speed) function can be used to adjust the output speed of some channels for a specific model. For example, in the landing gear retraction, users may want it to be opened slowly, therefore, you can slow down the output speed of the corresponding channel.

TYPE: EXP, VTR and CRV.

NOR: To adjust the end point ratio on the right side of the slave channel. For example, if the NOR is set to 50, then when operating the master channel, the end point of the slave channel on the right side is only 50% of the master channel. The adjustment range is between -100 and 100. A positive number indicates that the slave channel and the master channel move in the same direction, and a negative number indicates that the slave channel and the master channel move in opposite directions.

REV: To adjust the end point ratio on the left side of the slave channel. For example, if the NOR is set to 50, then when operating the master channel, the end point of the slave channel on the left side is only 50% of the master channel. The adjustment range is between -100 and 100. A positive number indicates that the slave channel and the master channel move in the same direction, and a negative number indicates that the slave channel and the master channel move in opposite directions.

RATE: Set the EXP, VTR, CRV curve rate of the slave channel. The adjustment range is between -100 and +100.

OFFSET: Set the central point of the slave channel.

PROG.MIX 2/2

When the curve is set to a negative value, the greater the negative value, the lower the sensitivity of the joystick in the neutral position and the higher the sensitivity at both ends; when the curve is set to a positive value, the greater the positive value, the lower the sensitivity of the joystick in the neutral position. The higher the sensitivity in the neutral position, the lower the sensitivity at the ends. The settable range of is from -100 to +100.

VTR：

VTR: The output range in the first half of the stroke is the current set value, and the output range in the second half of the stroke is 100/-100 minus the current set value. The settable range of the curve is from -100 to +100, and the positive and negative values represent the opposite direction of the servo.

POINT: the critical point of the VTR curve. The settable range is from 0 to 100. For example: when the VTR is set to 30 and the point is set to 70, the value output by the first 70% of the joystick accounts for 30% of the original value of the joystick.

CRV：

Set a 9-point curve type from the lowest point to the highest point of the channel. For example, if point 1 is -100, it means that the travel amount of point 1 is -100, and if point 2 is -75, it means that the travel amount of point 2 is -75. The starting amount of each point is the marked position of the previous point.

3.5 THROTTLE CURVE

The throttle curve can make the throttle operation more sensitive or smooth during acceleration and braking, making the throttle action change linearly or non-linearly.

TYPE: EXP and CRV can be set.

EXP：

EXP: Adjust the sensitivity of the throttle from the center point to the high point. When the curve is set to a negative value, the greater the negative value, the lower the sensitivity of the joystick at 50% throttle, and the higher the sensitivity at low and high throttle positions; When the curve is set to a positive value, the positive value The larger it is, the more sensitive the joystick is at 50% throttle and the less sensitive it is at low and high throttle. The settable range of the curve is from -100 to +100.

CRV：

Set a 9-point curve type from the lowest point to the highest point of the throttle. For example, if point 1 is -100, it means that the travel amount of point 1 is -100, and if point 2 is -75, it means that the travel amount of point 2 is -75. The starting amount of each point is the marked position of the previous point.

3.6 THROTTLE HOLD

Throttle hold, or the cruise control function can set the throttle output to a fixed value. When the throttle hold is turned on, the throttle output will jump to the locked position regardless of the current throttle position. For example, when using a crawler, you can turn on the cruise control with a switch, and the crawler can maintain a constant speed without touching the trigger.

SWITCH: SWA, SWB, SWC, SWD, SWE, SWF, SWG or SWH.

THRO: Fixed output value of the throttle. The setting range is 0 to 100, 0 means the fixed throttle output value is -100%, 50 means the fixed throttle output value is 0%, and 100 means the fixed throttle output value is 100%. When setting parameters, you can check the set throttle output value through the bar of channel 3 below.
