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 [broken link removed; example no longer available]. 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 [broken link removed; tutorial no longer avaialble] 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.
