Has the ION GPIO port got a voltage protection circuit? If I were to send more than the 12v would I damage the analogue input circuit?
Background: I have an emergency stop button that is being cabled by an XLR to the DB15 connector on the back. I want the button to be around 10m away from the desk. I'm wondering if buying a power supply to increase the voltage send by the button would cause issues to the ION's GPIO port. I'm concerned that just by adding a 12v DC power supply one end would actually not work due to voltage drop.
Increase the wire cross section to avoid voltage drop.
