how do i connect the servo trigger to a wireless ps2 using a playstation servomotor controller interface/ what do i do with the servo trigger power terminals? the playstation servomotor controller interface provides the power to the servos and will also to the servo trigger?
In short, you don’t. Both control servos so there’s no reason to connect a controller to another controller because the first controller is all you need.
What is it you’re trying to accomplish? Knowing that we might be able to steer you in the correct direction.
Yes but the ps2 is wireless and the servo trigger is wired. I’m trying to control the yahboom pan tilt servo set up which is wireless using the ps2 hand held wireless hand held and add the servo trigger to that same remotely controlled pan tilt device using the wireless ps2 hand held buttons. The servo trigger is wired. Is that clearer to you?
Btw the servo trigger is the 3rd servo on the remote pan tilt device. So pan and tilt, 2 servos, are controlled by the ps2 wireless and I want to control the 3rd servo, the servo trigger, using the ps2 wireless . maybe this helps understand the situation
Is this the device you’re using?
It’s capable of controlling six servos all by itself. Why not just connect your 3rd servo to that and use your existing remote?
I’m not really sure what it is you’re doing and working with. Some photos showing what you’re trying to do would be helpful.
I will send pics. The 3rd servo is the servo trigger. It has its own power supply and uses a momentary switch to activate it correct? And that servo is hard wired. If I connect it to the ps2 and use the switch on it to activate it I think it will give it an additional voltage not just act as a momentary switch. Understand? I don’t want to burn out the servo trigger circuit board or the playstation servomotor controller interface circuit board. Understand?

The servo trigger is wired and has it’s own power supply. How do I connect the servo trigger so it functions using the wireless ps2 that have their own power supply?
It does not appear possible to connect a servo trigger board to your product. Sorry. 
Let me ask you this. What would happen if I shorted the momentary switch terminals of the servo trigger board and connected the servo trigger battery terminals to the 6vdc output terminals of the playstation servomotor controller interface board? Wouldn’t that be the same as if the servo trigger was wired as it should be?
The servo would move to the B position and stay there forever.
These two boards are not compatible with one another. The only way to make them maybe work would be to connect a 3rd servo to the ps2 board and have that press a button that is connected to the servo trigger board. I don’t see the point in that when you could just skip the servo trigger altogether.
Wont the servo do whatever it’s programmed to do as long as the 6v is applied? And will keep doing it and wont stop until the 6v is cut off? I am working on a RF switch set up but would rather try to make the ps2 work.
I’m not sure what you are saying you don’t see the point in that I can skip the servo? I need three servo functions. Pan, tilt and servo trigger. Can you clarify how I do that by skipping the servo trigger altogether?
When you say skip the servo trigger altogether are you saying i can make a non servo trigger do the same function using an additional ps2 servo? I.e. going from pt a to point b and back to point a? Won’t that require changing the pulse width and adding more commands to do it. That would require figuring out the firmware etc.
You should grab a servo trigger and experiment at this point…and/or go through its hookup guide to get an idea of how it operates
With all due respect that’s your technical support answer?
My answers are above. Im sorry they are not the answers you’re looking for but that’s the reality of the situation.
Thank you. So there is no technical person who knows the design of the servo trigger? Reality is what you want to believe. Space x wouldn’t be around if Elon Musk believed what ULA and the rest of the world wide aerospace industry believed reality was.
We aren’t here to argue…if you don’t accept the answers then you should experiment on your own.
Your question makes it sound like you haven’t watched the product video or perused the hookup guide linked above; start there
Your non answers tells me you haven’t either. Go take 2 aspirins and get some rest maybe you will feel better in the morning and improve your bedside manners
