Hi all


I have a Micron TX22x transmitter,
fitted with self centering momentary toggle switches.

For lights, I program my RX6x receivers,
so the lights are latching when the toggle switch is moved up/down.

I have a RX41d-22 v510
I can't find a [LATCH_1] in the RX41d v510 programming instructions.


My question is:

Can I program P outputs on a RX41d to latch on/off,
when a momentary toggle switch is moved up, or down, on the TX22x ?

It appears from the Deltang site,

that you would need latching toggle switches to do what you want?

Yes,  That is my conclusion.

But hoped there maybe a genius out there with a work around.


Otherwise I'll retro fit a RX6x receiver.

Rod,

You could create a latching circuit for momentary triggers,
e.g. by using an SR Flip Flop.

But you have to tailor it for your application,
and it needs a little additional space, and additional wiring.

If you are not familiar with logic gates and Flip Flops etc.
it's worth anyway to research a bit about it,
and maybe learn something new. 

Personally I think I would create a Flip Flop from 2 NOR gates,
and care for sufficient output current to drive the 2 LEDs,
if I would be forced to use this Rx.

But honestly, I would simply replace the Rx to an Rx6x type.

Thanks Juergen, 

I think I will change the RX from the RX4x to an RX6x. 

Much simpler for me, though the retrofit will need some care.

Hi.

The RX41d-22 can easily be programmed to use latching switches.


It's the second row for "P" outputs on the corresponding DT website:

http://www.deltang.co.uk/rx41d-v510-p.htm


'high' stick <1s on/off or 'low' stick <1s on/off is what you need.

Claus,


Will that work for non-latching toggles? 

All my TX22X switches are momentary on, or have to be held on.


In any event I have replaced the 41d with a 63a. 


I have reprogrammed P2 as 3.2.2.3.1

and LED_2.Light is behaving as required on P2.

Hi Rod,

Yes that's true, this feature seems to exist in v510,
and you can use this with your momentary switches.

I apologise but, it seems I have looked in v520, rx41d-v520-p.htm,
and there this feature doesn't appear.

So sorry, for being misleading.

Thank you to Claus for the heads up, and Juergen for the confirmation.


I have programmed my Deltang Rx41d-22 v510 receiver,

to turn a LED on/off from a 'momentary centre-off switch' on a TX22X transmitter.

I would like to disarm the LED2 Rx41d.

The program code is flash = Other
2 flash = LED2 & PWM

1 flash = LED2 Disabled
2 flash = LED2 Enabled

1-3 flash = LED2 Pad P1-3

1 flash = 12Hz PWM
2 flash = 60Hz
3 flash = 130Hz
4 flash = 300Hz
5 flash = 700Hz LED2: use a Pad that is driving any LED


Question is.
What PWM should I select for 'normal' running?

Hi Rod,

From my experience with H0 and 0n30 drives for Gn15,
the best choice for good crawl speed behavior on the one hand,
and low motor noise on the other, is to use 60 Hz.

So test if the motor runs smoothly with it. 

But as experience is the best teacher,
you should also test the other frequencies,
to see, and especially hear, the differences.

Hi Rod,

It will depend, amongst other things, on the type of motor.

A traditional cored motor,
will probably work better with a low frequency, 60 Hz as Juergen says.

Whereas a coreless motor,
would probably work better with a high frequency, say 700 Hz.

I have a problem with a Deltang 45b-v510 (car).

The Pad for brake lights seems to be working backwards.

Lights on when motor running.
Lights off when motor stops.
Lights on a few seconds later.

Can Anyone advise.

When all else fails, read the instructions.

David Theunissen & Andy Rutter have been a source of enlightenment.

LED on Rx4x have the cathode connected to the P output.
LED on Rx6x have the  anode  connected to the P output.

Brake lights work as expected now.
