Well, I finaly decided that I should give this new 2.4 a try. :shock:
I've ordered a two way Frsky hack module from GiantCod and a couple of rx's. These have been despatched and should be with me in a day or two.
I intend to initially mount it in it's own little box externally and connect up through the trainer port on my Multiplex MC303 in a similar manner to one of the M-Link modules. If it all goes OK and I decide to make the switch over to 2.4 completely, I'll hard wire it inside the case. :?:
WIll keep you updated
-
Got home tonight and the bits had already arrived from GiantCod
Here's what was ordered:
1TX telemetry Hack module
1 8 Channel telemetry capable RX
1 4 Channel standard RX

Maplins tomorrow for a small case to put the hack module, aerial & bind switch in, plus a 7 pin DIN plug for the trainer port

Hi Bill, be careful as any adaption may void your BMFA insurance !
We had a problem with this in the past , but over came it as the electronics guy was able to certify his adaption.
Hopefully the rules may now be relaxed as these modules are being widely used.
-
Hey Bill,
Do you have the schematic for the MPX ppm etc plug ?
On another note, I'm going to receive this for evaluation :

Hub and sensors are already on the way to me :D
-
Thankd Fred & Richard.
Can't see what the diference is between this and plugging a spektrum module in to any TX and they're accepted. As you say Richard with them being widely available I guess the regulation has been relaxed a little. Also I think it's the same thing as the little orange RX's. As long as I do my checks properly before flight and ensure everything is OK I think I'll be OK
Fred, yes I have the pin outs for the Multiplex, so can probably get going today as bought a little case for it and plug last night at Maplins
-
Hi Bill, as we were told at the time, " once you modify any tranmitter you void the manufacturers specifications"
In our case we adapted a module to fit a multiplex tranny. The CE mark was void according to the authoritys.
We argued a point on the first edition modules that the module had expossed wires and in its self was not safe , nor did it meet the standard required for a CE mark.
The company that made the modules recalled all the modules and supplied a module with no wires on the exterior free of charge.
The new modules have the arial on the module as pictured in Freds post.
THIS WAS NOT A MULTIPLEX MODULE BY THE WAY !!!!
I think there are different rules applied to transmitters than receivers .
-
Fingers crossed for no accidents then! :?:
If I could afford it, I would go the full Multiplex route, but it's Very Very expensive cmpared to everything else apart from Jeti
& Weatronices. There was talk of a Spektrum module for the 3030, but I've never seen one
ps In ths States changing Xtals voids their insurance!
-
Bill,
Can you post the schematic here ? :D
I think I'll move my Royal Evo to 2.4ghz too... Then, MC3030!

Why move to 2.4 anyway !
You now have nothing to blame for crashes.
I am going back to 35mhz.
I do still use 35mhz and I'm well pleased with the signal.
I had to buy a 2.4 system as some competitions insisted on using it.
Spektrum was the only light weight receivers at that time.
Airtronics would be my choice of system if I were to go into 2.4 again
:wink:
-
Moving because there are now too many "rogue" flyers out there. I may only use 2.4 on bigger, more expensive stuff which is why I'm doing it this way. There is a switch available, that once everything is inside the TX case willl allow me to swicth between 2.4 & 35.
On the insurance note, I checked the unit and it has a CE mark on the back. Not sure if that counts for much?

Fred, I've emailed the pin outs ,but found this on converting a Cockpit on the T9 website
"Conversion for MPX Cockpit SX Documented by Peter Barnet:
To use the FRSKY V8 hack module with the MULTIPLEX COCKPIT SX transmitter will
require the following items:
(1) a 7- pin din plug
(2) a small plastic box
try Maplins for both of the above.
For the sake of simplicity the pin numbering of the din plug is as follows :
From the inside of the plug eg the solder side, the pins are numbered in a clockwise
direction starting from the left hand pin which is no. 1. Then following around in a
clockwise direction to no. 7 which is obviously on the right-hand side.
Solder the signal wire to pin no. 3.
The red wire to pin no. 4
The black wire has to be soldered to pin nos. 5 and 6
Insert the module into your chosen box, drill two holes in the box to take the
binding switch and LED. Basically that is the conversion over with ... you can
attach the box to the back of your transmitter with velcro or you can build it into
your transmitter tray as I did.
Fit the 7-pin plug to the charge/trainer socket on the top of your transmitter and
switch on. The LED on the module should glow red and the display on the transmitter
should read DSG which shows that the transmitter thinks it is running a flight
simulator programme. A second press on the transmitter jog wheel brings up the
normal operating screen for the transmitter as would be if you were operating on
35mg. Obviously there is no 35mg being radiated from the transmitter."

Perfect Bill, thanks for that :D
-
As a result of my emploer trying to shaft us on pension rights and me being on strike today, I got a bit done today:
Here's the module in a case with the aerial conection & bind switch through the side
(http://www.gliderireland.net/forum/images/uploads/billscottni/side.jpg)
(http://www.gliderireland.net/forum/images/uploads/billscottni/top.jpg)
Now only need to solder on the DIN plug before I can test it
-
That's looking very neat Bill! :clap:
-
Hey Bill,
While I was away, I received the latest FRSky goodies (must be one of the first in Europe!).
That is looking really really good!
Anyway, I try to plug that to my MPX, but I have an issue with the PIN outputs!
Can you confirm that :
1= +
3= -
4= PPM
I have your documents, but they all not show the same thing (but they seems to agree on 3 and 4)
And I'll plug all that to the Royal Evo, and I'll take some photos :D
-
Don't have it to hand at the moment, but I think 2 is + and you have to link 4 & 5 together for PPM - it disables the RF on the TX
-
Ok, thanks Bill.
That's for the Evo first, so I can turn off the HF.
It's from the MPX plug seen from the rear right ?
Sorry, lots of stupid questions in there!! :oops:
-
From the rear, counting left to right clockwise
-
Thanks Bill :clap:
Found my voltmeter, feel better! :D
I keep you posted
-
Hey Bill,
Took a bit of time tonight to setup the DHT-U module.
All good, module light up, and transmit as I can bind the receivers and I receive the informations on the screen of the module, but>>> when I move the sticks, nothing is happening! :!: :!:
Do you have to do something on the mc3030 after you plug the module via the Train/charge port ? :?: My light is red beside the on/off switch when I plug the module.
I played with the teacher / pupil function, but no clues! :!:
The red light, to me, mean that the TX is not transmitting I guess, because there is something plugged on the port :?:
How yours works? You just plug and play?
-
red light on the TX means it's not transmitting through the TX aerial. It should be transmitting from the module.
-
Ok, cool, thanks Bill.
I'll have another look tomorrow :D
-
Alright so, had another look!
The module is still not working (only turn on and receive data, but nothing is send to the servos :!: ) when I use the trainer / charge port!
Same thing on the 3030 and the Royal Evo! :!:
So yestarday, after checking that all the input were correct etc, I plugged the module directly inside the radio, on the module bay in the Evo. And success!
Sooooooo now, the question!
Any ideas why the PPM signal is not working on the trainer prt? And that's on both 3030 and Re9! :!:
For the Re9, I don't mind, I'll convert that one fully to 2.4, but for the 3030, I want to keep both 35 and 2.4ghz... Can't find nothing on the web about the PPM signal being out on the ports for the 2 radios... :?:
Anyway, the Info return on the radio is very cool! :D Can't wait to test the vario, but already having range and onboard voltage, is a big plus for the big gliders :D
