+## Graupner HoTT.ua
+
+Enable text configuration of the HoTT RX and sensors: Vario, GPS, ESC, GAM and EAM.
+
+Need OpenTX 2.3.9 or above. Located on the radio SD card under \SCRIPTS\TOOLS.
+
+Notes:
+- Menu is used to cycle through the detected sensors.
+- It's normal to lose the telemetry feed while using the text mode configuration. Telemetry will resume properly if the script is exited by doing a short press on the exit button.

  The Deviation project (on which this project was based) have a useful list of models and protocols [here](http://www.deviationtx.com/wiki/supported_models).
 
 ## Useful notes and definitions
-- **Extended limits supported** - A command range of -125%..+125% will be transmitted. Otherwise the default is -100%..+100% only.
-- **Channel Order** - The channel order assumed in all the documentation is AETR. You can change this in the compilation settings. The module will take whatever input channel order and will rearrange them to match the output channel order required by the selected protocol. 
+- **Channel Order** - The channel order assumed in all the documentation is AETR. You can change this in the compilation settings or by using a precompiled firmware. The module will take whatever input channel order you have choosen and will rearrange them to match the output channel order required by the selected protocol. 
+- **Channel ranges** - A radio output of -100%..0%..+100% will match on the selected protocol -100%,0%,+100%. No convertion needs to be done.
+- **Extended limits supported** - A channel range of -125%..+125% will be transmitted. Otherwise it will be truncated to -100%..+100%.
 - **Italic numbers** are referring to protocol/sub_protocol numbers that you should use if the radio (serial mode only) is not displaying (yet) the protocol you want to access.
-- **Autobind protocol**:
+- **Autobind protocol** - The transmitter will automatically initiate a bind sequence on power up or model/protocol selection.  This is for models where the receiver expects to rebind every time it is powered up. In these protocols you do not need to press the bind button at power up to bind, it will be done automatically. In case a protocol is not autobind but you want to enable it, change the "Autobind" or "Bind on channel" on OpenTX setting to Y for the specific model/entry.
 
-1. The transmitter will automatically initiate a bind sequence on power up.  This is for models where the receiver expects to rebind every time it is powered up. In these protocols you do not need to press the bind button at power up to bind, it will be done automatically. In case a protocol is not autobind but you want to enable it, change the "Autobind" (or "Bind at powerup" on OpenTX) setting to Y for the specific model/entry.
-2. Enable Bind from channel feature:
-   * Bind from channel can be globally enabled/disabled in _config.h using ENABLE_BIND_CH.
-   * Bind from channel can be locally enabled/disabled by setting Autobind to Y/N per model for serial or per dial switch number for ppm.
-   * Bind channel can be choosen on any channel between 5 and 16 using BIND_CH in _config.h. Default is 16.
-   * Bind will only happen if all these elements are happening at the same time:
-      - Autobind = Y
+## Bind on channel feature
+   * Bind on channel can be globally enabled/disabled in _config.h using ENABLE_BIND_CH. Any channel between 5 and 16 can be used by configuring BIND_CH in _config.h. Default is 16.
+   * Bind on channel can be locally enabled/disabled by setting "Bind on channel" or "Autobind" per model for serial or per dial switch number for ppm.
+   * Once activated, any bind will only happen if all these elements are happening at the same time:
+      - Bind on channel = Y
       - Throttle = LOW (<-95%)
-      - Bind channel is going from -100% to +100%
-
-* Additional notes:
-  - **It's recommended to combine the bind switch with Throttle cut or throttle at -100% to drive the bind channel. This will prevent to launch a bind while flying** and enable you to use the bind switch for something else.
-  - Using channel 16 for the bind channel seems the most relevant as only one protocol so far is using 16 channels which is FrSkyX. But even on FrSkyX this feature won't have any impact since there is NO valid reason to have Autobind set to Y for such a protocol.
+      - Bind channel (16 by default) is going from -100% to +100%
+      - **It's recommended to combine the bind switch with Throttle cut or throttle at -100% to drive the bind channel. This will prevent to launch a bind while flying** and enable you to use the bind switch for something else.

 Notes:
- - model/type/number of channels indicated on the RX can be different from what the RX is in fact wanting to see. So don't hesitate to test different combinations until you have something working. Using Auto is the best way to find these settings.
- - RX output will match the Spektrum standard TAER independently of the input configuration AETR, RETA...
+ - The "AUTO" sub protocol is recommended to automatically select the best settings for your DSM RX. If the RX doesn't bind or work properly after bind, don't hesitate to test different combinations of sub protocol and number of channels until you have something working.
+ - Servo refresh rate is 22ms unless you select 11ms available in OpenTX 2.3.10+
+ - RX output will match the Spektrum standard TAER independently of the input configuration AETR, RETA... unless on OpenTX 2.3.3+ you use the "Disable channel mapping" feature on the GUI.
  - RX output will match the Spektrum standard throw (1500µs +/- 400µs -> 1100..1900µs) for a 100% input. This is true for both Serial and PPM input. For PPM, make sure the end points PPM_MIN_100 and PPM_MAX_100 in _config.h are matching your TX ouput. The maximum ouput is 1000..2000µs based on an input of 125%.
-    - If you want to override the above and get maximum throw (old way) uncomment in _config.h the line #define DSM_MAX_THROW . In this mode to achieve standard throw use a channel weight of 84%.
+    - If you want to override the above and get maximum throw either uncomment in _config.h the line #define DSM_MAX_THROW or on OpenTX 2.3.3+ use the "Enable max throw" feature on the GUI (0=No,1=Yes). In this mode to achieve standard throw use a channel weight of 84%.
  - TH_KILL is a feature which is enabled on channel 14 by default (can be disabled/changed) in the _config.h file. Some models (X-Vert, Blade 230S...) require a special position to instant stop the motor(s). If the channel 14 is above -50% the throttle is untouched but if it is between -50% and -100%, the throttle output will be forced between -100% and -150%. For example, a value of -80% applied on channel 14 will instantly kill the motors on the X-Vert.
+ - To allow SAFE to be ON with a switch assignment you must remove the bind plug after powering up the RX but before turning on the TX to bind. If you select Autodetect to bind, The MPM will choose DSMX 11ms and Channels 1-7 ( Change to 1-9 if you wish to assign switch above channel 7 ). Then in order to use the manuals diagram of both sticks "Down-Inside" to set a SAFE Select Switch Designation, you must have Throttle and Elevator channels set to Normal direction but the Aileron and Rudder set to Reverse direction. If setting up a new model with all channels set to Normal you can hold both sticks "Down- OUTSIDE" to assign the switch with 5x flips. Tested on a Mode2 radio.
+ 
+Option=number of channels from 3 to 12. Option|0x80 enables Max Throw. Option|0x40 enables a servo refresh rate of 11ms.

-The "AUTO" feature enables the TX to automatically choose what are the best settings for your DSM RX and update your model protocol settings accordingly.
+"AUTO" is recommended to automatically select the best settings for your DSM RX.
 
-The current radio firmware which are able to use the "AUTO" feature are erskyTX (9XR Pro, 9Xtreme, Taranis, ...), er9x for M128(9XR)&M2561 and OpenTX (mostly Taranis).
-For these firmwares, you must have a telemetry enabled TX and you have to make sure you set the Telemetry "Usr proto" to "DSMx".
-Also on er9x you will need to be sure to match the polarity of the telemetry serial (normal or inverted by bitbashing), while on erskyTX you can set "Invert COM1" accordinlgy.

 # Flashing from the Transmitter
 
-For radios running erskyTx and OpenTX, there is an option to flash a precompiled firmware file to the multiprotocol module using the transmitter's Bootloader mode.
+For radios running erskyTx and OpenTX, there is an option to flash a precompiled firmware file to the multiprotocol module:
+- OpenTX: using the SD card browser
+- erskyTX : using the transmitter's Bootloader mode.
 
-## Tools required
-* A compatible transmitter running an erskyTx bootloader v2.9 or newer. This is true for both OpenTX and erskyTx.
+What you need:
 * A precompiled multiprotocol firmware file (.hex for Atmega328p or .bin for STM32)
 * A **Flash from TX** bootloader installed on an Atmega328p or STM32 multiprotocol module
 * A means to get the firmware file onto the transmitter's SD card
 
-## Radio bootloader and apps
+## OpenTX 2.3.3 or newer
+1. Copy the firmware file to the radio's SD card - it doesn't matter where you put it
+1. Switch the radio on normally and use the radio menu to locate the file on the SD card
+1. Highlight the file and press the ENTER button
+1. Choose Flash internal module or Flash external module as appropriate

 ### Finally
-Once the **Freq** value is known it should be applied to all other models which use this protocol and, if they were previously bound, the receivers must be re-bound.

-For convenience this can be applied once for all per protocol using the FORCE commands described below in `_Config.h` (or `_MyConfig.h`) configuration file.
+Usually all RXs using the same protocol&sub_protocol can use the same **Freq** value but it can't harm to do all of them.
+If you change the Freq value it is best to rebind the receiver(s).

+For convenience the freq value can be applied once for all per protocol using the FORCE commands described below in `_Config.h` (or `_MyConfig.h`) configuration file.
 These settings can also be used to force different tuning values for different multiprotocol modules, removing the need to alter the tuning option on the transmitter when swapping between modules. (Assuming that the modules also share a common hardware ID.)
 
-**Note:** If a forced tuning value is set in the configuration, it cannot be overriden by the protocol's **Freq** option on the radio for any model.
