VMIX Control Types explained for iQ series consoles (QOR - iQ, iQx, iQs)

Updated 1 month ago by Brett Patram

Scope

The current QOR IQ, iQx and iQs series offer multiple Control Type options for the V-Mixer. These options allow you to change the behavior of the V-Mixer when controlled using GPIO logic.


Disabled

The VMIX input channels are manually controlled by ticking the ON check boxes in the web gui.

This disables the Logic Port preventing GPIO control of the V-Mixer. Multiple Inputs can be in the ON state at the same time.


Normal

The active GPI pin state controls the input channels ON or OFF state

This operates the same as in earlier QOR software versions. Multiple Inputs can be in the ON state at the same time.

Example:

Pin 1 while held low (active) turns input 1 of the mixer ON. When Pin 1 is high (inactive) Input 1 turns OFF

Pin 2 while held low (active) turns input 2 of the mixer ON. When Pin 1 is high (inactive) Input 2 turns OFF


Toggle

A pulsed GPI pin state controls the input channels ON or OFF state

Similar to a Push on/Push off behavior. Multiple Inputs can be in the ON state at the same time.

Example:

Pin 1 when pulsed low, turns Input 1 ON (if it was previously OFF), Pin 1 when pulsed again, turns Input 1 OFF


Radio

A pulsed GPI pin state controls which input channels is exclusively ON.

There will always be one Input channel that is in the ON state, the rest will be OFF.

Example:

Pin 1 when pulsed low, turns Input 1 ON and Input 2,3,4 and 5 are turned OFF

Pin 3 when pulsed low, turns Input 3 ON and Input 1,2,4 and 5 are turned OFF


Note about GPIO logic

In Livewire GPIO "ports" have 5 Inputs (GPI's) and 5 Outputs (GPO's). When mapping the V-Mixer Logic Port to a physical Axia GPIO port or virtual GPIO port (IP Driver for example), all 5 pins in both directions are utilized to control and monitor the V-Mixer.

The Modes mentioned above change how the GPI pins control the V-Mixer. GPI Pin 1 will always be related to V-Mixer Input 1, GPI Pin 2 will always be tied to V-Mixer Input 2 and so on. The same goes for the GPO pins. GPO Pin 1 will go Low (active) if V-Mixer input 1 is ON, and so on. With this known, the logic is perfectly matched for Axia GPIO film cap button panels and IQ expansion frame with user buttons. When the logic is assigned in the Axia IP Driver - automation systems that can use the LWRP protocol can also control the V-Mixer. Perfect for a simple studio or satellite source switcher

The multiple V-Mixers found in the Fusion and Quasar Studio Engine are not controlled in this same way. The V-Mixer's in those products are controlled differently and requires Pathfinder routing software, where the IQ series can be directly controlled via a GPIO logic port.
