15. General purpose inputs are available as both TTL and isolated inputs At any time the software running on the NI 1450 can read these inputs The primary difference between general purpose inputs and trigger inputs is that you cannot use general purpose inputs to initiate a timed pulse generator In an application use the general purpose inputs to get the status of the inputs at a given point and not to synchronize the NI 1450 system with an external event An example of how to use general purpose inputs is reading the status of a general purpose input as the first step in your inspection sequence and recording that value as part of your inspection General Purpose Outputs General purpose outputs are also available as both TTL and isolated outputs At any time the software running on the NI 1450 can drive these outputs high or low The primary difference between general purpose outputs and timed pulse outputs is that the timing of general purpose outputs is controlled by software rather than hardware As a result timing of general purpose outputs changes as the inspection algorithm changes which makes general purpose outputs less appropriate than timed outputs for camera control strobe light control and other applications that require precise timing NI 1450 Series Compact Vision System User Manual 4 8 ni com Chapter 4 Digital 1 0 Functionality An example of using general purpose outputs is driving a relay that turns on an Inspec
