Digital Out over Parallel Port (LABView6.1@Win2000)

[Rene_Oce]

Hi, i`m trying to control a stepengine controller over the Parallel Port. I`ve to send 8bit words (such as 00100111, 00010001)in a row. I think i need the OutPort.vi. But how can i send the 8bit words in a row?

You can either use VISA or the replacement for the Out Port that you can download here. You need the replacement because the shipping functions will not work with Win2k. If you had LabVIEW 7, you would not need to do this. There is a tutorial here about using the parallel port and it contains links to some examples. To send more than one word, you just have to have your VISA Write or Out Port in a loop that autoindexes an array of values.
