12FG, 12Z, 14MZ, FX40 module programming

[MZFAN]

Hi everybody!
Following are some information on how to set your module area and Frequency. It is necessary in some countries where Futaba 'forgot' to implement some legal frequencies...:mad: Unfortunatly in some case you might need to change the radio area too which is another story.
If your radio is set for the right area but your module is not or have different area/frequency than you need you can reprogram it.:wink:

The first thing to know is that these information are kept in the module in a Microwire 16 bits 93C46 EEPROM.
Then you have to build a simple serial programmer (see joined files) and install a serial EEPROM programming software like this one:
http://www.lancos.com/prog.html

After that, reading and changing the data from the EEPROM is very easy and with no risk for the module. But don't forget to backup the original data in a file before playing around. That way you can mess around and still be able to go back.:thumbup:
You'll find all code correspondances and schematics in the zip file below. But don't forget that your settings have to match your radio for the area and possible frequencies in this area or you will have the 'mismatched module...' message when you start.
If you get the 'mismatched frequency...' message then it is OK you just have to set again the frequency for your current model.


I have heard of some 'all areas modules' but didn't find something like this yet.
I am interested in your experiences, please share.:noteworthy

Don't see why this is needed.
I have used 35 mhz, 50 mhz, 72 mhz, in my 12Z with no problems. Get the freguency mismatch message when modules are changed. But just push OK and go on and the frequency list is there.

[apleichau]

I have posted before to explain the reason to change the frequency. In Hong Kong, the legal 40mz frequency only includes 40.665-40.695. We can only get the MZ module of China version which only includes 40.770-40.850. I have bought the China version of MZ module in Hong Kong and sent back to Futaba in Japan for modification to the legal frequency. After 40 days they refused and sent it back through Hong Kong Distributor without any explanation. Is it interesting?

Hi David,
To use both 35 50 and 72 MHz on the same radio you probably had to change the area of the radio. Am I wrong? Doing this is easy with the 12Z but more difficult with the 14MZ or FX40.
It doesn't seems that there is any 'Futaba's area' that will permit this... Or the 14 MZ are not all the same in the world.
As apleichau said if you are not in the main 'Futaba's aeras' in the world then you really might need this.

Hi MZFAN,
I think the 14MZ has 2 versions, one for Japan and one for the rest of the world. The Japanese one don't allow you to use other module besides the ones for Japan. The Japanese one also don't have 12ch PPM even with the latest update.

Hi benben,
What make you think this? Personnaly I don't think so. I have access to japanese and none-japanese 14MZ and didn't see such difference. Of course if the none-japanese 14MZ I used is in fact a modified japanese 14MZ it could be...

If there are some differences it could be more like asian, european and american 14MZ. But not many people are willing to share information on this subject and it will be hard to find out.
Thanks for your comment.

[benben]

It makes me think this because I tried using a 36mhz module for the Japanese 14MZ and it woudn't let me use it while it worked on the Hong Kong version and the Taiwan version. Do you know how to change the Japanese version to other version?

Thanks
Ben

[MZFAN]

Benben, this is interesting but strange. I know how to change a 14MZ to another area but this information is not welcome on this forum...

[benben]

MZFAN, are you using the utility program you posted before to change area?

[idhoverman]

MZFan, you r DA MAN!!!

I would guess that Futaba differentiate the MZ14/12 module from FX40 module in this EEPROM too :-)

Now that we have established how Futaba (1) set the region and frequency band in the transmitter (2) set the region and frequency band in the TX module, for experimental purposes, it would be interesting to see on how they set the frequency band in the receiver. Would it be sufficient to replace the little pcb plugs in the receivers with one from other frequency band, or would it need other changes. It is just worrying to plug and unplug this little slave board from the main receiver board for too many times.

Hello David
I call Alexander and I write from Italy.
I ask excuse for English, have bought the Futaba 12z in China (Hong Kong), have need of aid, you can explain like is made to me to change the frequency to the module and to carry it to the European zone?
Thanks Alexander

[DavidH]

Should be fine. Just stick 35 mhz or 40 mhz module in transmitter. At least that has been fine from what I have seen.

I have the module from 40 Mhz

Hi MZFAN,

I have a T-12FG from Hong Kong.
First when I plugged in the european HF-Module I got the message "modul mismatch".
So I follow your description to change the region code of the module and it works fine.
But now I can only use the frequencies allowed in Hong Kong channel 75 to 82 .
I think I have to change the region code in the transmitter from Hong Kong to european to get use of full 35MHz range.
Can you tell me how to change the region code in the transmitter ?
Please help.

[MZFAN]

There are some instruction on this forum (sticker) for the 12Z and I know how to do it for the 14MZ but I don't have any idea for the 12FG. Sorry...

Anyone know if the region code in the TM-14 (FASST) module can be altered with this same method?

[nicolas.goddeeris]

The question is, is the FASST module TM-14 region locked or not. It might be different than the conventional modules, as the legal frequency tables do no longer apply. Futaba USA has just put this question to Futaba Japan but they are at this very moment still closed for their New Year holidays. (See Futaba Support Forum on RCU). Everyone is awaiting the answer !

[nicolas.goddeeris]

And yes, I am also looking for somebody who can add the frequency 34.930 MHz to the 14MZ. European frequencies start with 34.950-...

[MarkD]

Channel 55 (34.950) is the lowest legal use frequency allowed (in the UK anyway). That's why it's not available on the Frequency Screen

[nicolas.goddeeris]

Correct. But you might have understood that was not my question. ;-)

[FredericG]

When I first read MZFAN's post I thought he meant the EEPROM contains some sort of look-up table listing all frequencies the module can generate. After studying the attached documents I suppose it just contains a country-code and a frequency band. The country-code and band values are than mapped to a list of possible frequencies inside the transmitter. As different countries allow different channels in a given band, this mechanism allows to access more frequencies. Right?

What Nicolas would like to do, is using a frequency that is outside the predefined 35Mhz ranges.

Does anybody have more info on the internals of these RF modules? At some point the radio must communicate to the RF module what frequency to generate. Does anybody know how this works?

Thanks,
Frederic

[DavidH]

From my understanding the 35 mhz module will only generate the frequencies that are used in the 35 mhz for Radio control. As for the difference between which one are used. I would think that is controlled thru the region coding. For example a transmitter with Europe/UK region code will allow different 35 mhz freqs than a Europe only region code.
Same way with the 72 mhz freqs. The Japanese only have access to 10 72 mhz freqs. While here in North America we have access to 50 of the 72 mhz freqs.

[MZFAN]

Hi,
As FredericG said the possible frequencies are mapped in a table in the radio software. There is one frequency table for each area. By changing area and or frequency in the module and radio, you can only choose which table will be used. But you cannot use a frequency that is not in your area and certainely not a frequency that is not in any area. That is one of the reason why an update is necessary to use 2.4GHz.
If you want to use a completly new frequency like Nicolas, well, you will have to hack the radio software... Which is far far more difficult!:(

[sinver]

Hi ,

MZFAN,

I be ready to prove the change of area of Hong Kong to Europe in a Futaba
12FGA bought in Keimod.com but emerge me certain doubts


As have to configure the Pony Prog ? ( to see photo attaches )

SI Prog API or SI Prog I/O or JDM API ? :shock:

and the rest of parameters of invert in white ? ( Invert reset, invert SCKL, etc )


thanks & regards !!! :wink:

Hello, i m just reading this post and i have a info and a need help too, i explain :

I have a T12FG europe with 41 module, and i have bought a TM-14 modulle ( FASST ) in USA, and this module doesn't work with my T12, it's have a region code, that write on the manuel of module too.

Do you know now if it's possible too change it like the other module ?
