Production Switchers

Running a Vision 3 v 16.0a MD. Want to control 8 GPO's but NOT through a custom. I have it working so that when I select a certain crosspoint, it triggers a GPO (an audio rail), BUT when I select a different crosspoint, I want to fire the first one again (bring the first GPO'd rail down) and then fire the GPO associated with that second crosspoint switch. Is this possible?

Is your GPI a pulse or level? If you use a level, could you program your audio console to bring the rail down on loss of input?

In your scenario, if you put XPT A in program, it fires and holds GPO 1 as long as its in program. Then when you select XPT B in program, it fires GPO 2, which cuts off the level on GPO 1 (since its no longer in program), thus killing the voltage input to your audio console.

What is happening is when I select XPT B it does kill level on XPT A...but doesnt bring up the level on XPT B

What I want is XPT 1 (GPO 1) on air...when I select XPT B (GPO 2) I want GPO 1 to go down and GPO 2 to come up. Is that possible?

You're using the GPIOs that are configured in the BNC menu correct?

Unfortunately it's only possible to assign one GPI output to a BNC using this method. If you want to fire multiple GPIs you'll have to use a custom control.

If you really don't want to use custom controls to trigger the the crosspoint selection and multiple GPIOs you could do a GPI loopback. The GPI output triggered by selecting the crosspoint would loopback into the switcher and trigger a GPI input that triggers a custom control that triggers multiple GPO outputs (tongue twister!).Only limitation there is the number of GPI pins on the Vision.

Can your sound device be triggered by both the presence of AND loss of voltage? Using a level GPI, then, the switch goes on, rail up. Switch goes off, rail down. That way you don't need another GPI to tell it to pull the rail down; the loss of connection does that. Then you use your second GPI to tell it go send rail 2 up.

Yes Garner I am in the correct menu...hmmm I have to think about your suggestion...its making my head hurt
