The 68-pin motion I/O connector provides all the signals for four axes of 
closed-loop motion control, including encoder feedback, limit and home 
inputs, breakpoint outputs, trigger inputs, digital-to-analog (DAC), and 
analog-to-digital (ADC) converter signals. Refer to Chapter 5, 

, for details about the signals in the motion I/O connector.

The 68-pin digital I/O connector provides 32 bits of user-configurable 
digital I/O. Refer to Chapter 5, 

, for details about the 

signals in the digital I/O connector.

The PCI-7340 RTSI connector provides up to eight triggers to facilitate 
synchronization between multiple National Instruments products. The 
PXI-7340 RTSI-enabled connection provides up to eight triggers and one 
PXI star trigger to facilitate synchronization between multiple National 
Instruments PXI-enabled 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. You also can use the RTSI bus for general 
hardware-based communication between RTSI devices.

The RTSI bus also can be used for general-purpose I/O. Refer to Chapter 5, 

, for details about RTSI connector signals.
