LOGIC INPUT

Go to the Logic Input page of Conference Composer. If the SWITCH OUT wire is connected to Logic Input pin 1, then you need to assign Pin 1 by left-clicking the desired pin in the DB-25 graphic and selecting the pink color (The pink color means that the pin is not grouped to other pins).

Now, right click in the ACTIVATED COMMAND column for Logic Input 1 and select INSERT, INPUT, 1, MUTE, ON. Now, whenever the switch goes Active Low (0V DC), the Vortex Device will mute Input 1.

Now, right click in the DEACTIVATED COMMAND column for Logic Input 1 and select INSERT, INPUT, 1, MUTE, OFF. Now, whenever the switch goes Active High (+ 5V DC), the Vortex Device will unmute Input 1.

To accomplish this, we will use the BROADA command to send MUTEI commands from one unit to the other unit. The BROADA command broadcasts any command that is after the colon. For example, if a Macro in the Vortex EF2241 has this command Page LOGIC INPUT Page Page LOGIC OUTPUT Make sure the LED works as designed. If you press the membrane switch, you should see the LED above the pins illuminate in Conference Composer as well as on every MX392.
