6.4.11 Digital I/O Application
The Digital I/O Application only appears if the Digital I/O backplate is installed at either one or
both channels in the instrument, see section 8.8 Backplate Options. The application provides
the user a place to assign conditions or actions to the digital inputs and the digital outputs, the
default screen will show all inputs and outputs turned “off”. Each channel has three inputs and
three outputs. Each input can be assigned by clicking on the name of the input and then selecting one of
the options listed on the right. The logic of the switch can be reversed by pressing the Invert Logic (Yes/
No) button. When a digital signal (switch closure) is sent to either of the input terminal on the back panel
of the CPC6050, the instrument will perform actions based on the options assigned to the input.
