MRT Transponder question.
 

A fellow visited our track recently and had a ptx transponder. Our AMBRC system wouldn't read it. We are using B&B autoscore software. I did look it over and saw that it was plugged in correctly, and the blue light was lit up. Anyone else have this happen or have any adeas for me? This racer says the transponder works fine at another track he races at.??????

I use B&B Autoscore myself. Never had a problem with either custom or clone PTX's. Try it in another car?? try changing the number??

Keep us up to date.

What version of the transponder system do you have Is it the New Mylaps or have you had it upgraded from Mylaps

Did the system work with other MRT's

Just a warning to tracks that MLaps has found a way to make the MRT's not work with the Upgrade they do or if you get the new mylaps system

Larry I have replied to you on the 'MRT PTX Personal Transponders' thread http://www.rctech.net/forum/8549089-post82.html but will post part of my reply here:

It is possible (a definite answer is not easy to give) that the problem could be related to what I can best describe as 'decoder/transponder tuning' a technical issue that can occur whereby a transponder is not recognised by one decoder but is by others. The data signal sent from a transponder to the decoder is coded/encrypted, sort of like a car key code, if the signal data cannot be decoded the transponder will be detected by the decoder but will not show up on the system/software. It is also possible for a transponder to show an incorrect 'random' number on the screen (which can be rather confusing) this particular 'glitch' can (it happens very rarely) be caused by a corruption of the signal data transmitted/emitted by the transponder. Without getting too technical, decoder systems do sometimes have glitches but thankfully not often for most people to realise, it's usually race control that are likely to come across these things.

It is possible that issues with numbers can be related to the decoder firmware version being used, the 'hybrid' part is also a potential factor that could cause problems. I won't go into more details here for reasons of not wanting to complicate matters, until the new MyLaps system is out it's best just to hold fire. Without going into the technicalities suffice to say more problems from numbers not working are likely in the future, this applies to AMB, Mylaps and also MRT transponders.

There can be problems with numbers not working. The AMBrc system and the MyLaps system both use the same system numbers. System numbers get recycled and reused after transponders have been back to AMB/MyLaps for upgrade, replacement, trade in etc. System numbers at times also can end up getting blocked due to an error, the same transponders sent in for repair and meant to be scrapped are returned instead of new replacements with new numbers.

As Ed suggests try changing the ID number (this is possible with MRT PTX transponders) the numbers can be changed to another stored number or with custom ID's reset to another system number.

We have a AMBRC system, this is the first person to try a MRT transponder here. Still looking for answers, anyone else had a problem like this?

Larry,
I've tried my own PTX's at 2 local tracks with the AMBrc decoder... both using AutoScore. My own micro track there are about 8 PTX's (mine is the only clone)... this is an AMBrc3 system running AutoScore. And there is another local track using an rc3 decoder... it could be a MyLaps...running rcscoringpro... probably more then 15 there... none of us are having problems.

How was the transponder mounted? I've seen them mounted every way... but AMB, MRT, and MyLaps all recommend them laying flat.

Myself,.. I keep a 4 cell holder handy. If anybody asks they can plug in and run just the pt over the loop... eliminates every thing else.

It was mounted flat, and the blue light was on when I looked it over.

Can anyone confirm that the new AMB software nullifies the MRT PTX transponders?

I can. I recently upgraded the decoder at our track, from that point forward the MRT transponders no longer work.

Yes we can. They still work under practice settings, but wont work for race settings.

We have the new rc4, and either racing or practice, it is hit and miss. You will get 4-5 laps counted, then 2-3 misses, etc...

Seems there is a newer MRT model, can anyone confirm if this works with my laps RC4?

Thanks!

It's supposed to work, but who knows if it will next year, or the year after.

It's not that much cheaper, so why bother.

The only way to block the new mrt is to block all the amb dp transpoders...

Yes it works with rc4

I have a bunch of them that should be delivered this week. I can then confirm that they work with the new system.
