Micron RC - Deltang Rx replacement MR603a

[Phil.P]

You should be OK. - Famous last words!

Older stickers have a gold ground, the newer ones are silver.


I acquired a gold-sticker RCT-Tx10, with a loco, the other day. - This means it is quite early, and it does exhibit the fault.
Of course, it will be fine with the loco I acquired it with.

Anyone with a RC Trains transmitter that exhibits this behaviour, get in touch, at the usual email address.

Thanks Phil! It's silver. Sounds like I should be ok for when I do get one of the new Rxs!

Phil a silver "hologram" sticker with "Warranty" on it, that is what is in mine. Having looked at my Micron Tx, I have not noticed any identification

[Phil.P]

Jimmy,
As stated, you should be OK.

I started adding the stickers, as it gives me an idea of when the transmitter was manufactured.

I am led to believe, the faulty code, was only loaded to a few months of 'production'. So it depends if DT mass-loaded modules, and how many 'we' bought from him during that period.

This will affect any 'make' of Deltang-based transmitter of this vintage.
So Spoerer, Chuffed2Bits, RCS-RC, and others.
(Note: Spoerer changed to remove Omni reference.) PP.


I have repaired Transmitters made by others, and will (presently) continue to do so..

I have contacted Andy (Micron) and he has given me this information:

There have been reports of transmitters with pre v207 firmware failing to bind. These would be at least 6 years old. The solution is to have the firmware reloaded which I can arrange.

[Old Man Aaron]

I'm a bit late to the party here, but it's great to see the new Rx'es are finally available. I think we owe Andy a debt of gratitude for all the work involved in continuing the Deltang system. Personally I need about a dozen receivers for all the projects in my cupboards - and to have a couple of spares. Too many other expenses at the moment though..

Given the popularity of Deltang, and the massive proliferation of cheaper loco kits over the last few years, I'd wager Andy will be inundated with orders for quite some time!

[Phil.P]

Anyone wishing to use two-wire bi-colour LEDs, connected BETWEEN Pins 1&2:

You will require a firmware update (to v1.1) if you have a first-batch MR603a.

I have a number of MR603a, which I will get updated with the new firmware.

NOTE:
This does NOT affect ordinary LEDs, connected between receiver pins and battery.
It is only this one specific instance, of connecting bi-colour LEDs between Pins 1&2.

I have read most of the information in this thread and understand little or none of it! However, I have picked up on one interesting post which seems to apply in my case..... I have been given a brand new Micron DSM2/DSMX receiver and installed it in a loco which previously had a Deltang Rx65 unit fitted, so I know the wiring is correct! However, the Micron unit will not bind with my RC Trains RCT-Tx22 transmitter. Is this due to the age of the Tx, which is one of the first made by Rik when he set up RC Trains?
The Micron Rx will flash slowly at first (on the face of the board) then a brighter, more persistent, flash (on the reverse of the board) takes over and the unit will not bind. Any suggestions will be gratefully received.

[philipy]

I'm no expert, but it sounds to me as though you may have one of the early ones which now need their firmware updating. No doubt Rik or Phil P will be able to advise with more authority.

Yes, it's the most likely scenario. Either buy a new TX or if you are good with soldering, buy a new TX2 board (which I think are £20 ish) and just replace the board.

Saying that I am sure someone on here would di it for you if need be

[Peter Butler]

Thanks Steve, sounds like a plan! I can do some soldering, but I wouldn't have the fine skill required to mess about with electronics, I can foresee the whole thing melting in my hands. I would certainly be grateful if someone could do this for me please.
I presume the rest of my Rx units would still function as before????

[ge_rik]

As Steve says, the Tx2 board inside the Tx22 will be old stock. I had to replace four of the Tx2 boards in my six transmitters. They are £20 plus postage from micron - http://www.micronradiocontrol.co.uk/tx_ ... tml#dt_tx2

As Steve says, it's a simple swap, like for like, but does require some soldering. I can do that for you if you like.

[Peter Butler]

Thanks guys, I have now contacted Phil P. and he has agreed to do the necessary upgrade to the Tx and ensure the two items are enjoying conversations together!
It seems that not all MR603a's get along with the Tx22 and they might need to be formally introduced.
I'm grateful for your responses.

Excellent, glad to hear you have it all planned and sorted now

[ge_rik]

Glad you've got it sorted
