BRB900 changing transmitter destination address

Postby martymonsta » Thu Apr 14, 2016 9:18 pm

I've got an LCD BRB 900 and 2 transmitters, I brought the transmitter and 1 of the transmitters as a pair, they have the same Destination Address. The 2nd transmitter has a different Destination Address. I have X-CTU software so can change the Receiver to match either transmitters. I want to be able change the Destination Address of the Transmitter, the User Manual says it can be done, but I can't work it out. In xb3 I can only get a screen that looks like this

Can someone please tell me what I'm missing.

Thanks Marty

Hey mate, so you want the one Rx to receive both Tx - right?

Noel and I did this a while back IIRC when we first got our BRB900 and doing some testing...

My version of xb3 is 018u a bit older it seems, and again, IIRC you change the ATDT value and then write it to memory.

BUT - this is a sketchy memory at best, so maybe do some more research. Hope this at least gets you headed in the right direction...

In fact, I had a chat to Greg Clark about this in 2014!!!

LOL "bottom line, the ATHP, ATDT and ATID values need to match, or you need to start getting creative with the value of ATMK."

Thanks Jase that does help, I think it is a software thing. I'll have a chat to you about this tomorrow.

Thanks Jase for offering to flash my BRB on the weekend, everything starting to blow away and the RRC3 had me distracted. As it turns out I had asked the same question on the other forum and Greg from BRB replied with a work around.

"If you plug the receiver into your PC via the USB, you can run X-CTU and modify the parameters. Easiest way to modify the transmitter would be to swap the RF module into the receiver, make the changes there, and swap it back.

With one receiver and two transmitters all using the same ATDT parameter, the receiver will echo all received packets onto the USB interface. However, it will only display the first one it hears based on the serial # of the transmitter."


It took all of about 3 mins for me to get it done, and it works a treat.

A WORD OF WARNING. You can really stuff things up with X-CTU so be really careful.

Yeah, been there / done that!! Lucky I made a backup of the settings to file and was able to "unbrick" the receiver...

Hey Marty no problem, happy to help a fellow rocketeer anytime.

Good that Greg got back to you with that work around.

I had my BRB and an egg thingy ready to go on the day but got so busy with everything else I just didn't bother putting them in - would have been good for the data but with 8,000ft flights landing 100ft from the flight line I though to myself *meh* she'll be right.

I'll test them both out next month - the BRB did get me out of the $hit at Thunda.

It is fun processing the data afterwards though.
