8.5 Digital Inputs/Outputs (DIO)
8.5.1 DIO Inputs
The 4220HD series DIO’s can be user defined as either input or output circuits. The default settings are DIO 1
and 2 are configured as inputs, but each DIO can be configured as an output if required for installation
requirements.
8.5.2 DIO Outputs
The Outputs can be set up to be latched or momentary with programmable momentary duration. When an
event is generated by the 4220HD’s Command Core + software the Output acts as a switch to I/O Common
to control external components (the controlled device ground must be referenced to the camera's I/O
Common).
Caution: Do not connect a power source to the inputs.
Caution: The source voltage for any Output must not exceed 50 V, and the maximum sink current must not
exceed 250 mA.
