Hi,Norbert!

It is much more a downgrade or a backgrade! You have to connect you ProfiTX with you PC and than you must start the MULTIPLEX-Launcher - download from MULTPLEX homepage. It offers a special menue for the PTX-transmitter.

You hardly can make a mistake - the 3.76 Version has already been deletet from the list. Of course, you lose same features in your modelsetups but the different memories should still work - but please make sure that it is really so!

good luck

Hi Profimc,

Many thanks,it is very simple.

I had the old version software, that's why I'm trying to test the new 3.56 for the reach field

I have an RX-16-DR pro M-LINK Order number 55815
connected to a height sensor.
2 x new receivers but always the same problem distance. Less than 100 meters.

also without sensor tested the same problem., shame but 2x crashes with large gliders

Does this have to do with the 2.4 GHz frequency module?

What can I do about this, bring it back to the dealer.

can you help me further please

Norbert

Hi, Norbert!

So your old version was the 3.76 that is beeing critisized at the moment?

I have had 3.76 in use as soon as it was available - so far without any problems, like all the other users in our club. With the MULTIPLEX warning we all have gone back to 3.56 which had been in use for a quite long time before the 3.76 version occured. To my memory there had been hardly any problems with SW 3.56.

I would recommend to go back to version 3.56 and test the components on the field in a rangetest and on a cheap flyer. If there is no satisfying range or you are not sure about it send the equipment to the MULTIPLEX-Service. At the moment you might need some patience with waiting for the return.

with regards

Hi Team,
Many thanks for your quick anser.

the version of my profi tx was 2.24 - 2.42 I don't know anymore.
I thought it had and old version that could cause problems, normally this has nothing to do with the high frequency, but maybe
on the receiver (rx-16-dr pro) you can see that I have signal error.
visually the distance is +/- 100 meters,
But in a short distance a check it goes up to 40 to 50 meters
maybe you will find this information useful

Many thanks
Norbert

Hi, Norbert!

I don't want to create the impression I would belong to the MULTIPLEX-team. I am a user as you and so many others. It is just some experience that I want to give on to you!

So version 2.24 or even 2.42 are among the first software version ever released. It is unusaul to have range problem with these. Of course, the receiver might collect some "errors" but this is no natural indication for a proper transmitter or receiver probelm it can be but it needn't be. Radiocontrol means that there might be interferences even with 2.4 GHz technology - in most cases we don't even get the idea that there has been a blocking, a missing signal or what ever.

I would get nervous, if there are to many errors and a far too limited range. But as I said before: try different receivers on cheaper models or by performing a rangetest. Errors that occur above a 50 to 60 meter range in a rangetest should be seen as pretty normal. Especially with an RX-DR-16-pro even in a rangtest distances of more than 100 meter should be without any problems. But, of course, other things (terrain, trees, fences, hig-voltage lines etc.) might have an influence on the test.
To find out if the receivver is the bad partner you might test it with a different transmitter - I know, it is easy to say that for me - I own some five or six tranmitters using M-LINK signals. But if in such a test it turns out that the receiver is ok the tranmitter ist left to hold the baby.

If you are unsure don't risk a model, send the equipment to the MULTIPLEX-service.

good luck and with regards

Hi
are your recevers up to date with the old software you are running on your TX you might still need to up-date your recivers.
I have been using DR 16 recivers for a long time now and never had any issues with them they have been bullet prove up to now,
one more thing make sure you up-date HF as well tot he latest version and one more thing make sure your aerials are 90 d to each other and that they are not near some carbon in the fuselage

Hi,

the receiver software versions no issue. All versions should work fine. Neverthless an update is recommendable.

The transmitter needs an update for the HF-part. I 'm not sure whioch update of the main software requires the HF-update, but you cant miss it. If it is not done, the system just doesn't work and there is no receiver activity!

Hi Profimc,

I always thank you for the quick response. You have given me good advice, what I have already done is the following.
I did a distance test with the profi tx and an older multiplex MC4000 (2.4Ghz) and the distance was the same for both Transmitters.
and de seem receiver.
The disappointment is de distance is not as great as I thought.
The receiver is being held by a person, and then I have done the distance test +/- in steps 200 Meters
I also did a test flight (with an old plane and cheap)with the Profi tx transmitter without any problem.
What I will do next week is an old glider and put the receiver in there and do a distance flight,
Will inform you about this next week.
I'm also going, to do a test with a spectrum dx9 transmitter and a distance test, with the same condition as the Profi-tx. And then I am curious about the step distance if it is the same.
I will also inform you next week.
Manu thanks, again for the support and the quick response

Regards,
Norbert
