Curve: Curve settings Diff Adjust the stroke amount on one side with the midpoint as the boundary Expo Expo curve setting. Increasing a positive value will make the gimbal smoother and smoother when approaching the midpoint, while increasing a negative value will make the gimbal more acute when approaching the midpoint.
4.4.4. Mix control (Mixer) Mixing page for channel settings The mix control page allows you to combine as many input sources as you want and map them to any one or more of the 32 output channels. Finally use the next page (Outputs) to make these purely logical outputs to fit the model device You have complete flexibility in controlling the mixing from any input to any output channel. A mix puts one input into one channel. The inputs are configured in the Inputs page, which defines any input type.
Please note that the currently active row of settings will be displayed in a bold font, making it easy to recognize the item currently in use at a glance. The CH1 channel shown in the figure is input by the Ail gimbal, and the three states of the SA switch are used to switch three stroke amounts. To edit a mixing control, use the scroll wheel to select the mixing control item up and down, and press and hold the ENT key to enter the editing submenu. Select Edit and press the ENT key momentarily.

Negative values indicate reverse channel output. Offset: Midpoint offset, you can add the offset of the input value, positive or negative.
Diff Adjust the stroke amount on one side with the midpoint as the boundary Expo Expo curve setting. Increasing a positive value will make the gimbal smoother and smoother when approaching the midpoint, while increasing a negative value will make the gimbal more acute when approaching the midpoint.
Delay Up/Dn: The response of the output can be delayed as the input changes. (In seconds). Slow Up/Dn: Regarding input changes, the response of the output can be slowed. For example, slow speed can be used to slow down retraction driven by a normal proportional servo. The output will cover the time in seconds from 100 to + 100%.
4.4.5. Output（Outputs） Total output page, final channel output overall settings 4.4.6 Curves The curve can be used to modify the control response in the Inputs, Mixes, or Outputs page. Standard curves containing Expo and Differential can be used directly in these sections. This page is used to customize any kind of curve.
The curve can be between 2 and 17 points and can have a fixed or user-definable x coordinate.
Smooth：If checked, create a smooth curve through all points. When customizing, move the cursor to X and Y coordinates, and change the position of each coordinate point according to your needs. Depending on the type selected above, this allows writing the X coordinate of a standard curve, or the X and Y coordinates of a custom curve. Long press the ENT key on the coordinate point to enter the submenu： Preset：Select presets with slopes of -45 °, -33 °, -22 °, -11 °, 0 °, 11 °, 22 °, 33 °, 45 °.
By using the "Adjust GVx" option in the Special Functions page, you can even adjust global variables on the fly, so you can quickly optimize settings such as doublerate ratio, exposure, differential, flap to elevator conversion, and more. If pop-ups are enabled (indicated by! Next to the GV label), when the variable is updated, a pop-up window with the variable name and new value will be displayed on the main view.
Name: Setting name Unit: Units, switchable between normal and% Precision: Precision, which can be used in decimal mode. You can set this mode corresponding to the percentage. Min: Minimum value, which can be limited when the value is changed dynamically Max: Maximum value, which can be limited when using dynamic change values FM0-FM8: You can specify a value for each flight mode or set it to be the same as the other flight modes.
The setting of the L01 example in the figure is expressed as follows: When the return value A1 is less than 11.0V, the L01 switch is automatically turned on. In the settings of other pages, L01 has the same function as the physical switch. You can define the corresponding function for L01 on or off. In this way, a switch is automatically executed according to the parameters that change in real time. The remote-control system provides 64 logic switches, each of which has three judgment methods: 1.
Triggered when the absolute value of parameter v1 is greater than v2, the |a|>x absolute value is that it will become positive no matter whether it is positive or negative |a|
to the value of data v2. Switch, this item only judges the difference when v1 changes from small to large Triggered when the absolute value of the difference of the parameter v1 |△|≥x itself is greater than or equal to the value of v2. This judges the absolute value. Since the negative value also becomes positive, a change from v1 to v or from v1 to trigger the current logic switch The switch that automatically loops all the time. V1 is the on time and Timer v2 is the off time.
-Use the switch to adjust the backlight brightness In addition to a few of the commonly used methods listed above, the everchanging features allow you to realize your imagination The three examples in the picture are represented as： SF1：When the SF switch position is ↑, the CH3 channel will be covered by -100. Usually this setting is used to lock the throttle. SF2：When the logic switch L01 is automatically turned on, lowbat (low battery voltage) voice will be broadcasted.
The following functions are triggered by the switch selected above Override Trainer Inst.Trim Override channel value Coach mode enable switch, it is recommended to set to SH rebound switch, this switch is used to activate or stop the operation of the student machine One-touch saves the current gimbal position as a fine-tuning value Reset Reset, you can choose to reset all or reset one way individually. The content of the reset option is the same as that in the main interface.
1x: Play sound once. 1s-60s: broadcast at intervals (seconds) Play Track Play wav file in SD card, single broadcast and loop broadcast are the same as above Play Value Voice broadcast value, can broadcast values from any source, such as real-time values such as gimbal, voltage, altitude, time, etc. Lua Script: Call the specified script, and the script file should be placed in the / SCRIPTS / FUNCTIONS / folder of the SD card.
There are some caveats-if the script stops executing, you should never use Lua model scripts to control any aspect of the model that might cause a crash. The reason is that if the script tries to use too much CPU time or memory, it will be closed and it will not run again when the model is selected. “The Custom Scripts page is for mixed-type scripts that run continuously. These scripts should be placed in the / SCRIPTS / MIXE / folder of the SD card. There can be up to 9 custom scripts.
It is not an absolute measurement, but a number that represents the ratio of the signal to some initial "good" value. The number is relative, but can indicate that the model may be close to the range limit of the controlling aircraft. When the return signal is completely lost, the remote control will prompt “Lost return signal”. Please note that due to a failure of the return link, the remote control can no longer warn you of RSSI or any other alarm conditions, so no further alarm sounds.
5. External UART And SI , SJ interface The TX16s has two externally accessible 5v UART ports that are direct output noninverted TTL. Aux 1 is a 4 pin TTL UART, Aux 2 is a 5 pin TTL UART with a CTR connection directly to the Radios MCU. IMPORTANT NOTE! Ensure the correct polarity and voltage are applied when connecting to UART interface. Do not apply more than 5v to the UART port at any time. External UARTS can be used for additional hardware and projects such as: Adding a Bluetooth module.
SI and SJ are assignable slots in OpenTX for an extra two 2pos switches and an extra 2 analog pots.
