GPIO and other connectors
GPIO
1 × GPIO (General Purpose Input/Output)
6 pins Phoenix plug, having 4 ports for On/Off control, GND
and +12V.
You can configure input/output integrations by using pre–
defined behavior. Exposure of states and commands for
external control requires external programming.
For information about the API commands, see the API Guide
for the codec, go to:

Usage information
•
A contact closure between the GND and a GPIO port pin is
detected as a low input signal.
•
When used for voltage inputs, the GPIO port detects it as:
•
Low signal for voltages 0 - 1 VDC
•
High signal for voltages 2 - 12 VDC
•
When used for outputs, the GPIO port acts as a switch
to GND, and is rated for 500mA @ 48V DC. The +12V pin
provides +12 VDC, and is capable of sourcing up to 500mA.
•
The GND connector is a common ground for all pins in the
GPIO port.
USB
