How could one send a specific data set to a 3rd party device and instrument using the Out Port vi?

I'm trying to control a Nanonics 3d flatscanner through an HV003 Three Channel High Voltage Bipolar driver ISA Board. I'm able to send a constant signal to it using the Out Port vi, which is able to move the scanner in one direction for the various x,y, and z axis. Is there a way to control the out put using the Out Port vi which would send a specified signal at a specified time in order to control each of the axis in a contolled manner. Thanx.

Hi,

as you for sure know, some "old" scanners use the printerport as interface to PC. But I expect that there is a microcontroller inside for correct timing and control. You will never have a determined timing at printerport, if there is Windows in between. For exact timings you will need additional hardware....., but this might be controlled from LPT.

uofc,

The Out Port and In Port VIs read and write hardware registers. It you want to be able to have these on for a specific time period, you will need to program that time by doing another call to the Out Port.vi. As for other timings, this will all need to be programmed into your application.
