Problem (probably me!) with Deltang Rx61-22 and Tx22.

I have a problem in that the Rx61 seems permanently bound to the Tx!

I've followed the paperclip info on the Deltang site,
from cycling through the no-select/select/select with Tx-change cycle to no effect, using P1 and P3.
Then a 'hard reset' using P1 and P2.
No difference.

It all started when I tried to rebind to a different channel.
All it did was add that channel.
Then again and again, until I have only channel 5 not controlling the Rx.

The reason for changing was that I wanted to swop this Rx61 for an Rx63,
to see if I could have a buzzer.

This was suggested to me in response to an earlier post, 
but I found the speed take up too quick to overcome the inertia of the Mashima 1020 motor,
powered via a boost board.

So I wonder if the Rx is faulty ?
But I feel it might really be me.

Any ideas appreciated - thanks.

Hi Peter,

The Rx6 receivers have the ability to be transferred from one Tx to another,
by the Tx Selecta switch.

To do this, the Rx is bound successively to each Tx using different Selecta position on each Tx.
It sounds like you have successfully bound the Rx to each Selecta position of the same Tx.
Not what you wanted but possibly not a faulty Rx, just the system working as designed.

I have not tried this myself,
but I think the hard reset will reset programming changes to factory settings,
but possibly not the binding information the Rx stores.

If you have or can get access to a second Tx22,
then switching the Tx change option off by the paperclip change,
and then binding to the second Tx might do the trick.

Failing that,
if you bound the Rx to the other Tx in other Selecta positions,
then I think that these would be freed up on you original Tx, if that makes sense.

Thanks Frank.

I'll give the 'hard reset' paperclip thing another go.

Sadly I only have access to a Tx20 which I got when I started out,
and copied your scheme for a Narrow Planet 009 Baguley-Drewry, over on another forum.

Since then I've acquired the Tx22 and moved up into 16mm battery locos,
with Rx63-22's as my preferred receiver.

I saw a reply from you to my 'wrong-place' post but can't see it now.
So thanks for that, saying that I can use the P1 pad on an Rx63,
with the bind button as a switch (hope I've got that right).

The buzzers I've got are <25mA so maybe they're a tad high?

Your advice and guidance is always appreciated.

Peter Smith

Edit: Actually it's not a Tx20 but a Tx21.

My experience is for normal use with Selecta and a Tx-22,
do NOT use the Selecta with Tx change option.

With Selecta option, just rebind your Rx to the Tx-22,
remembering to set the Selecta knob to the number you want.

I don't know if this is exactly how the Rx works,
but imagine it has 12 internal memory slots.

As new,it has the number 6 slot,
filled with the identifying unique 'name' of the Deltang 'test' Tx-22,
all other slots will be empty.

You can rebind to any Selecta number,
and it simply overwrites what is already there.

hHwever you cannot erase the contents of a memory slot,
that can only be done by a software reload.

The solution should be simple,
when the Selecta option is 2, Selecta WITHOUT Tx change,
the Rx simply uses the last Selecta number bound to,
and ignores the rest.

Phew, it is actually simple, but difficult to explain.

Hi Peter

The paper-clip reset doesn't clear bind data,
only receiver programming.

If you made any changes to an output function,
hard-reset will return the behaviour to the as-shipped configuration.

As you are using a Tx20,
you need to have Selecta disabled.

One of the Tx20 function buttons
( which one depends on whose Tx20 you are using,
look at the information sheet that came with the Tx2 )
operates R/C channel 2, which is the same as used by Tx22 etc, for Selecta.

So, if you enable Selecta on the receiver,
you will find it getting deselected when you push the Tx20 button.

Hi Peter,

I hope I got your problem right.

So you tried to rebind your Rx to the same Tx22, but only to another selecta-switch position?
And you did that several times with several switch positions and now the Rx obeys to all these switch positions?

The most senseful explanation for this behaviour is, that your Rx regards each of your switch positions as an own Tx,
so that it is to assume that your Rx is set to "Selecta + TxChange", but should be set to "Selecta" only.

I know, you wrote that you already tried to change the Selecta setting,
but perhaps you try once more.

And be aware that if you set it to "Selecta disabled",
your Rx will react independent from the Selecta-switch position and will work on all 12 positions.

Thanks Juergen.

I appreciate all the guidance and advice given to me on here.

Clearly I'm getting ahead of myself so hopefully a rethink over Christmas will be useful.

It's definitely me and not the Deltang stuff!
