I have been using Deltang in my H0 scale trains for a while now and love it, so much so that I am about to start swapping out my Aristocraft R/C in my 24th scale trains for Deltang RX65's.  I use Pheonix Sound cards and found this excellent article about using Pheonix and RX65's - https://riksrailway.blogspot.de/2017/08/triggering-soundcards-with-deltang.html.
This raises the question that I note the the TX20 has a couple more triggers (or switch's) than the TX22, can extra triggers be wired into a TX22 for activating some more sound effects on the Pheonix, I also note the these extra triggers in the TX20 go to unused pins in the TX22 module, so I presume they could be fitted. Any thoughts?

Hi Budd,
I use a Phoenix soundboard with DelTang as well. But I design my own DelTang transmitters.

In your case with your Tx22, you can use channel / Pin 7 to connect a 3-way self centering toggle switch. You wire this just like the switch on Pin 3 in the circuit layout of the Tx20 transmitter
Tx20 cicuit

Then you can use the high and low position of the switch to trigger 2 single sounds. You choose two pads (P -outputs) on your Rx65 and you assign both to channel 7, you set both to "idle high (3V)" and you set one to be low(0V) if channel 7 is high and the other to be low if channel 7 is low.

You can have one trigger more with a push button on ch/Pin 4, that will be connected like the switch on Pin4 in the Tx20 circuit. The assigned pad on your Rx is to be set to "idle high" , and to be low if ch4 is low.

If you don't  have already used the programming features of your Rx's, you will have to invest some time and brain for this. Tell me if you need help with this.

Basically all DT Tx's contain the same Tx2 transmitter board, which is free configurable.There are only set some presets for the the different Tx's.

Corresponding with David T it appears a subset of the Tx72 could provide control of numerous sounds with the appropriate rcvr. I purchased one to test but have not had the time to work on it yet (moving and setting up a new house takes too much time).

Yes, a multiswitch on ch7 is also possible. For sound triggering I would propose to use a set of push buttons instead of the 12 position switch, for a more direct access of the sounds.

All sounded good Juergen till you started talking about lows, highs and idle highs, I am neanderthal when it comes to this stuff, my greatest achievement is successfully assembling TX22 kits and fitting recievers, although I do have paper clip changes mastered!
I would prefer push buttons to activate sounds rather than toggle switches, on my diesel there is only the horn and grade crossing tone (no bells in Australia!), so can you talk me thru wiring 2 buttons to the TX22 and RX65-22, one to sound the horn, the other to sound the grade crossing., I would like to use the bind button for one and add another button for the other, hence my initial question.
I expect a steam sound to be the same button layout/set up, another issue to face down the track will be connecting a Sierra sound card to RX65, but that is for another day.
Thanks for any help.

Hi Wayne 

yes that’s sounds a bit cryptically, if you never dived into the programming possibilities of DT Rx’s. But it is not so difficult to explain. 

I will send you a pm.

Thanks for any help in laymans terms Juergen, I will slowly get my head around this stuff, should be for the better, is the prog4 from Deltang worth purchasing for programming?I sent a query to Pheonix, their helpful responce in full is:-
Hello Wayne,
We do not have any specific information on the Deltang systems and have not actually encountered on ourselves. THat being said, the brief information I could find online tells me it would follow our standard remote control hookup, such as the RCS or BelTrol systems. The two green wires from the P8 would go to your power - track or battery, polarity does not matter. The orange and gray wires would connect the the motor outputs of the RX65's esc (I believe they refer to it as H or H1?) The orange wire would connect to the lead that is positive (+) when the locomotive is going forward. The sound board trigger inputs can be activated from the outputs of the RX65, apparently they have both direct logic level (P) and buffered (F) outputs. Theoretically you could use either but I feel safer recommending the open drain (buffered, F) outputs since I have not had any hands on experience with these units.
Jim

I have hooked up the basic sound and it does work!I am aiming for bigger and better things now!
