This may be real simple but I'm not anywhere close to an EE I can ask for help.,
I have a +5vdc line that remains at +5vdc until I click a mouse to generate an event, Then the line goes to ground. (this is what I want) and after the PC controlled and timed event the line goes high again. (again, what I want).
The device I'm trying to control has a +13vdc voltage on the line I need to control. It works by having that +13vdc on the control line and starts it's events when pulled to ground.
So, In a nutshell I need to pull a 13vdc line to ground when triggered by the +5 volt line going to ground.
It's a PC controlled event that will take the +5 control line high again(and thus placing the 13 back in a + state as well when it's in a resting state.
I understand a 5volt spdt relay might work, but I have absolutely no idea how to wire it up. I'm not looking to goof with it once it's working. hopefully I've explained well enough for some step by step help. Thanks In advance. -Jim
The relay is the standard Radio Shack 'micro pc type' 5vdc 1A variety with five poles. The two different voltages come from completely different places, and are not connected in any way, ground or otherwise.
