APPENDIX A: GPIO CONNECTORS

AQONDA 8 and AQONDA 16 feature eight ground sensing GPIs and eight relay GPOs. A virtual link between
GPIs and GPOs of various devices on the same EtherSound network can be realized by means of the EScontrol
application. The GPIO pins are labeled 1 through 8 on the rear panel as illustrated.

The GPI status can be either "1" or "0".
Switching the GPI state to "0":
It is read "0" as soon as the pin labeled "K" on the scheme is
connected to ground, e.g. to a pin labeled "GND".
Switching the GPI state to "1":
Leave pin K floating
The GPIs do not need external power supply.
