User Connectors
The 68-pin motion I/O connector provides all the signals for two axes of
closed-loop motion control, including encoder feedback, limit and home
inputs, breakpoint outputs, trigger inputs, and analog-to-digital (A/D)
converter signals. Refer to Chapter 5,
, for details about
motion I/O connector signals.
The 68-pin digital I/O connector provides 32 bits of user-configurable
digital I/O. Refer to Chapter 5,
, for details about the
digital I/O connector signals.
The RTSI connector provides up to seven triggers and one high-speed clock
signal to facilitate synchronization between multiple National Instruments
products. Typical applications of the RTSI bus include triggering an image
acquisition or DAQ measurement based on motion events, or capturing
current motion positions based on events external to the motion controller.
The RTSI bus can also be used for general-purpose I/O. Refer to Chapter 5,
, for details about RTSI connector signals.
