Futaba Micro Trainer Port to DSM2/DSMX Module Adapter Board


I developed an adapter board which converts the PPM signal from a Futaba trainer port to a Spektrum DM8 DSM2 module or an OrangeRX DSM2/DSMX module (please read the note at the end of the post regarding the OrangeRX module).

This is a non-intrusive to the module version of the mod I showed here.

The board is compatible with most Futaba transmitters with the square micro trainer port connector. Here is a list of the compatible Futaba transmitters:

4YF
4YBF
6EX
6J
7C
8FG
8J
9C
10C
10J
12FG
14SG


It is NOT compatible with:

12Z
14MZ
18MZ
18SZ

I made a "Z" version of the adapter board which works with Futaba 12Z, 14MZ, 18MZ and 18SZ - Spektrumizing Futaba 12Z, 14MZ, 18MZ and 18SZ Transmitters.


Here's a kit of the adapter:


  • Adapter Board with a Futaba micro trainer port connector- fully assembled and ready to be used
  • Antenna - 2.4GHz 2db with RP-SMA connector
  • Strip of mounting tape
  • Strip of adhesive back velcro


What one needs to be able to fly Spektrum BNF models:
  • A DSM2/DSMX module - either the Spektrum or an OrangeRX.
  • This adapter board
If you decide to use the OrangeRX module you will need to re-flash it using this USB Firmware Update Kit. This allows the module to remap the channel assignment from Futaba's AETR to Spektrum/JR's TAER which is important if you want to fly Spektrum's UMX BNF models and your transmitter does not support channel remapping (4YF, 4YBF, 6EX, 7C, 9C).


What you need to do to use the adapter board with your compatible Futaba radio and the module:
  1. Stick the mounting tape to the back of the module approximately in the middle.
  2. Remove the backing from the mounting tape.
  3. Carefully plug in the module to the adapter. Make sure the mounting tape makes good contact with the adapter.
  4. Find a suitable place on the back of the transmitter and apply the velcro pieces to the adapter and the back of the transmitter.
  5. Carefully install the included antenna to the antenna connector on the module.
  6. Stick the module with the adapter board to the back of the transmitter.
  7. Plug the adapter connector to the trainer port of the transmitter.

Next you will need to bind the receivers or BNFs to the module. To do so first put the receiver in bind mode - with the transmitter turned off for regular receivers you insert the bind plug into the BIND/BATT port of the receiver and plug in a battery in any unused channel; for UMXs you just plug in the battery. The receiver will start flashing rapidly. Next, depending on which module you are using you have to do one of the following:
  • For the Spektrum DM8: With the transmitter still off, push the BIND button on the module and hold it down while turning on the transmitter. The receiver will stop flashing or flash slowly - keep the BIND button pressed down until you get a solid light from the receiver at which point you can release the button.
  • For the OrangeRX module: With the transmitter off, push the BIND button on the module and hold it down while turning the transmitter on. In approximately 2 seconds the module will beep at which point you have to let go of the BIND button. Wait for the bind process to finish which will be indicated by the solid light on the receiver.
Remove the bind plug from the receiver, turn it off as well as the radio. Turn the radio back on, then the receiver and check to make sure that everything works properly. For the UMXs and the Spektrum bricks you will have to reverse ALL channels which are used.

When using the transmitter in its native radio mode (72MHz, FASST, FASSTest or S-FHSS) unplug and remove the module. Of course you can keep the module on the back of the transmitter at all times if you choose so.

Keep in mind that when the transmitter is on and the DSM2/DSMX module and adapter board are connected to the transmitter trainer port, it will transmit both its native radio signal and the DSM2/DSMX signal. If you have a higher end transmitter like the Futaba 8FG, 10C, 12FG or 14SG you can prevent the transmitter from sending its native radio signal by holding down the RET button while powering up the radio - it will display a menu from which you can choose whether you want the radio to transmit or not. If you select NO from the menu it will not send its native radio signal but the DSM2/DSMX module still would transmit.

Keep also in mind that the DSM2/DSMX modules support up to 8 channels. If your radio supports more channels (8FG, 10J, 10C, 12FG, 14SG), only the first 8 are transmitted.

Here are some pictures of the adapter board, assembled with the module and on the back of the transmitter:

Initial Transmitter Setup


This is the procedure to set up the transmitter for use with a DSM2/DSMX module:

1. Create a new model. Select the new model.

2. Reverse channels 1 through 8. This is needed for compatibility with Spektrum which uses opposite channel reversing.

3. Leave endpoints (ATV) at 100% for now. Later you can tweak this if needed. I never had to change them with UMX models.

4. Set any dual rates and exponential you may want or you can leave this for later when/if you want to tweak the model. I found that UMX models need very little if any negative expo. My "standard" high/low rates for UMX models are 100/70% but most often I fly on high rates.

5. Note: This step applies ONLY to the stock OrangeRX module! If you are using a Spektrum DM8 module or you got the module from me do not perform this step!If using the OrangeRX DSM2/DSMX module stock, it does not reassign the channels from Futaba AETR channel sequence to Spektrum TAER sequence. This is crucial for flying UMX aircraft or any aircraft using the Spektrum "brick" receiver. This does not apply to the Spektrum DM8 DSM2 module or an OrangeRX module which has been reflashed with firmware which reassigns the channels. The channel assignments needed for flying UMX aircraft or aircraft using the "brick" receiver are:
Channel 1 - Throttle
Channel 2 - Aileron
Channel 3 - Elevator
Channel 4 - Rudder


This completes the initial transmitter setup. Next is binding the receiver or UMX aircraft to the transmitter. The procedure is slightly different for the Spektrum DM8 DSM2 module and the OrangeRX DSM2/DSMX module so I will cover the two procedures in two separate posts.

Binding and Using a Spektrum DM8 DSM2 Module


Binding:

1. Attach the Spektrum DM8 module to the adapter board if you have not done so already. I suggest that you use the double sided mounting tape for this to prevent the module from accidentally detaching from the adapter. Connect the antenna to the module.

2. Attach the module with the adapter board to the back of the transmitter. You can use the provided hook and loop material.

3. With the transmitter turned off connect the trainer connector to the transmitter trainer port.

4. Put the receiver in bind mode:
  • For a UMX, plug in the aircraft battery. The receiver will start flashing rapidly indicating it is in bind mode.
  • For a regular receiver insert the bind plug into the BIND/BAT port and connect a battery to the receiver or plug in a battery to the ESC. A receiver battery can be connected to any unused receiver port. The receiver will start flashing rapidly indicating it is in bind mode.

5. With the transmitter turned off press and hold the BIND button on the DM8 module then turn the transmitter power on. The module will start flashing indicating it is in bind mode. When the receiver no longer flashes rapidly you can release the BIND button on the DM8 module.

6. Wait for the bind process to finish - this will be indicated by the lights on the module and receiver coming solid on.

7. Remove power from the receiver and if using a standard receiver remove the bind plug.

8. Turn off the transmitter.

IMPORTANT: Specific to DSM2/DSMX receivers is that the fail-safe is set at the receiver during bind. Because of this the above binding procedure has to be performed for each model at least twice - once to establish initial connectivity between the module and receiver and a second time after the model set up has been finished. This second bind will set the correct fail-safe. If you make any major changes to a model set up, especially channel reversing, perform the bind procedure again.


Using the Spektrum DM8 module:

1. With the receiver power turned off and throttle stick all the way down, turn on the transmitter power. Wait for it to finish powering up and for the light on the module to come on.

2. Power up the receiver/aircraft. Wait for a solid light from the receiver indicating communication from the module to the receiver.

3. Perform a pre-flight check to make sure all control surfaces move in the desired direction.

4. Before the first flight for the day on that model do a range check. Place the aircraft on a surface at least 2-3 feet above the ground. Press and hold the BIND button on the DM8 module and walk 20 paces away - you should have control over the aircraft.

5. If the pre-flight and range checks are good, enjoy flying the aircraft.

6. After landing, remove power from the receiver.

7. Turn off the transmitter.

Binding and Using an OrangeRX DSM2/DSMX Module


Note: This post applies to the "original" OrangeRX DSM2/DSMX module which is no longer available. It may or may not apply to the newer OrangeRX modules!


Binding:

1. Attach the OrangeRX DSM2/DSMX module to the adapter board if you have not done so already. I suggest that you use the double sided mounting tape for this to prevent the module from accidentally detaching from the adapter. Connect the antenna to the module.

2. Attach the module with the adapter board to the back of the transmitter. You can use the provided hook and loop material.

3. With the transmitter turned off connect the trainer connector to the transmitter trainer port.

5. With the transmitter off, press and hold the BIND button on the OrangeRX DSM2/DSMX module and turn the transmitter on. Keep the BIND button pressed until you hear the module beep then release the button.

6. Wait for the bind process to finish - this will be indicated by the light on the receiver coming solid on. The light on the OrangeRX module can be off or flashing in series depending on the mode it determined during bind with the receiver and depends on the receiver (DMS2 or DSMX, 11ms or 12ms).

7. Remove power from the receiver and if using a standard receiver remove the bind plug.

8. Turn off the transmitter.

IMPORTANT: Specific to DSM2/DSMX receivers is that the fail-safe is set at the receiver during bind. Because of this the above binding procedure has to be performed for each model at least twice - once to establish initial connectivity between the module and receiver and a second time after the model set up has been finished. This second bind will set the correct fail-safe. If you make any major changes to a model set up, especially channel reversing, perform the bind procedure again.


OrangeRX DSM2/DSMX transmission mode:

The OrangeRX module determines the type of receiver during the bind process. Depending on the receiver the light on the module (see step 7 above) will be:
  • Off - the receiver is DSM2 1024-bit resolution, 22ms frame rate
  • Flashing once followed by a short pause - DSM2 2048-bit resolution, 11ms frame rate
  • Flashing two times followed by a short pause - DSMX, 22ms frame rate
  • Flashing three times followed by a short pause - DSMX, 11ms frame rate

The OrangeRX DSM2/DSMX module stores internally the transmission mode it determined during the last bind. If you use different types of receivers which require different transmission modes, note the transmission mode indicated by the module light and make a note on the aircraft or even better add this info to the model name in the transmitter. For example, add "D0" to the model name, meaning DSM, 0 flashes (DSM2 1024 bit-resolution, 22ms frame rate), "D1" for one flash (DSM2 2048, 11ms), "D2" for two flashes (DSMX 22ms) and "D3" for three flashes (DSMX 11ms). When you select a model to fly, check the note on the aircraft or the model name and see how many flashes the module indicates. If they don't match, change the module transmission mode by pressing the BIND buttons three times in quick succession. Every time you press the BIND button three times quickly the transmission mode changes to the next one - light off (DSM2/22ms or D0) to one flash (DSM2/11ms or D1) then to two flashes (DSMX/22ms or D2), then to three flashes (DSMX/11ms or D3) and then back to light off (DSM2/22ms or D0).


Using the OrangeRX DSM2/DSMX module:

1. With the receiver power turned off and throttle stick all the way down, turn on the transmitter power. Wait for it to finish powering up. Check the module light and whether it matches the type of receiver. If it does not - change the mode to match the receiver as described above in "OrangeRX DSM2/DSMX transmission mode".

2. Power up the receiver/aircraft. Wait for a solid light from the receiver indicating communication from the module to the receiver.

3. Perform a pre-flight check to make sure all control surfaces move in the desired direction.

4. Before the first flight for the day on that model do a range check. Place the aircraft on a surface at least 2-3 feet above the ground. Press and hold the BIND button on the OrangeRX DSM2/DSMX module and walk 20 paces away - you should have control over the aircraft.

5. If the pre-flight and range checks are good, enjoy flying the aircraft.

6. After landing, remove power from the receiver.

7. Turn off the transmitter.

Update Procedure for the OrangeRX DSM2/DSMX Module


Note: This post applies to the "original" OrangeRX DSM2/DSMX module which is no longer available. It may or may not apply to the newer OrangeRX modules!


This is the Update Procedure for the OrangeRX DSM2/DSMX Module for Futaba Transmitters with Firmware for Spektrum Channel Order (TAER). I am posting it here as it is relevant to the usage of the OrangeRX DSM2/DSMX module with Futaba transmitters.

The OrangeRX DSM2/DSMX Module for Futaba Transmitters comes from the factory with firmware which does not reassign the channel sequence. By default for Futaba these are:
Channel 1 – Ailerons
Channel 2 – Elevator
Channel 3 – Throttle
Channel 4 – Rudder
Channel 5 – Gear
Channel 6 – Flaps
The Futaba channel sequence is also known as AETR by the first letters of the functions assigned to the first four channels. The higher end Futaba transmitters provide channel reassignment but the mid- and lower end transmitters do not provide this flexibility.

Spektrum offers many attractive Ultra Micro (UM) models. These as well as the Spektrum “brick” receivers use the Spektrum (and JR) channel sequence:
Channel 1 – Throttle
Channel 2 – Ailerons
Channel 3 – Elevator
Channel 4 – Rudder
Channel 5 – Gear
Channel 6 – Flaps
The Spektrum/JR channel sequence is known as TAER – again using the first letters of the four functions assigned to the first four channels.

The Spektrum UMs use a “brick” receiver. A “brick” receiver consists of several otherwise separate components – a receiver, ESC and servos. The “brick” receiver may also have a stabilization device – in the Spektrum case this is the AS3X 3-axis gyro stabilization system.

In order to use the OrangeRX DSM2/DSMX module with the low- and mid-end transmitters which do not allow for channel reassignment and to fly the UMs or any other model with a Spektrum “brick” receiver, the module has to be updated with firmware which changes the channel sequence it receives from the Futaba transmitter in the AETR sequence to the Spektrum TAER sequence.

To update the OrangeRX module you will need the following:
  • 2S LiFe or LiPo or 5- to 8-cell NiCd or NiMH battery pack

To update the module to TAER channel sequence:

1. Install both USB device drivers. You may have to restart the computer after the installation finishes.


2. Make sure the jumper on the USB adapter is in the “Futaba” position. This tells the USB adapter that it is communicating with the Futaba version of the OrangeRX module.




3. Plug the USB adapter board into the module. Note the correct orientation of the adapter to the module on the picture below:




4. Do not connect the battery yet. Connect the USB adapter to a USB port on the computer. The green LED on the adapter will turn solid on.



Wait for Windows to recognize the USB adapter and apply the drivers to it. When it finishes installing the drivers you may continue with the next step.


5. With the battery still disconnected, start the update software:




6. The update software shows the following window:




7. With the battery still disconnected, click on the “Connect” button. The software status will change from “No Connected” to “Connecting” and the “Connect” button will change to “Disconnect”:




8. Observing the correct polarity, connect the battery to the USB adapter – the blue LED will come on:



The software status will change from “Connecting…” to “Connected”:




9. Click the “Open” button – a popup window will open:



Select the “ORX V1.09 (FT MapTo JR).bin” file – see above. If for some reason you want to bring the OrangeRX module firmware back to its factory default AETR channel sequence, select the “ORX V1.09 (No Mapping).bin” file instead. Click the “Open” button. The popup window will close and the update software will list the file and its path in the “Firmware File” box:




10. Click the “Update” button. The update process will begin and the green LED on the OrangeRX module will flash while the update process is running:




11. When the update process finishes, the green LED on the OrangeRX module will turn off and the update software will show an “Update Succeed” message:



Click the OK button to close the message:




12. Click the “Exit” button to quit the update software.

13. Disconnect the battery.

14. Unplug the USB module from the computer.

15. Unplug the USB module from the OrangeRX module.


That’s it! Now your module will reassign the first four channels from AETR to TAER.

Enjoy!

I do not make the modules from the link above. You should contact the seller.

If it is anything like the modified Spektrum DM8 module it will not work with a Futaba 12Z, 14MZ or 18MZ transmitter as they do not provide enough power through the trainer port which is needed to power the module. For that particular reason I made the adapter board for Futaba "Z"-series transmitters to be used with a stock DSM2/DSMX module with an external battery which powers the module.

Spektrum DM8 Module and E-flite EFLR310013 DSMX SAFE Receiver Compatibility Issue


Currently the Spektrum DM8 module would not work with the E-flite EFLR310013 DSMX SAFE receiver used in the Apprentice S 15e BNF. According to HH support "the dev team know about the issue and it is currently being worked on. But there is no fix right now." Here's a link to the original thread where this was confirmed:

Hi Ivan,
Are still selling the dsm2 adapter boards as I am thinking of upgrading finally from a Futaba 9c to the 10J but I have a mixture of Futaba and Spextrum receivers.
Many thanks.

I just wanted to drop in and say that Ivan has an excellent service here with the plug-and-play module.

After a hectic Friday/Saturday with graduation parties to attend, I finally got a chance to setup the module with my 14sg and I must say the this device is Outstanding! Clean and tidy. The uninitiated would never know that this device wasn't OEM.

This was a situation where I could have DIY the module but the convenience of Ivan's pnp option was an easy no-brainer.

Then, when you add to the fact that Ivan readily answered my questions, quickly assembled and sent out the module, and made sure that that I received it safely, it just made for an excellent experience - the first one, I might add, dealing with a specialist on RCGroups.

Thanks a whole bunch, Ivan!
