Using VISA to Access the Parallel Port in LabVIEW

Publish Date: Sep 06, 2006 | 69 Ratings | 4.03 out of 5 | Print | 8 Customer Reviews | Submit your review
This example uses VISA to write data to the parallel port. NI-VISA 1.1 was the first version that supported parallel communications. If you have an earlier version, this example will not work. When using the parallel port, pins 2-9 are data pins with pin 9 being the most significant bit. Also, pins 11 (printer busy) and 12 (printer out of paper) must be grounded to transmit data.

Controlling 3 stepper motors with LabView via the parallel port  - Aug 26, 2013

Hello! Need to control 3 stepper motors through the parallel port using LabView. I saw some information on how to use the parallel port, but I need to use it bit by bit, or need to send a bit driver will power regarding speed, the other for the direction of rotation and other related will enable the axis. All this 3 times, they are 3 axes. Do you have any examples for this type of communication?

3rd Party Parallel Port Card  - May 29, 2013

Hello. I have a problem accessing the parallel port using InPort.vi, OutPort.vi or the example in 203540.llb. I am using a 3rd party card for my parallel port. I cannot see or set the device address in the Device Manager (Windows 7). I think it is automatically set by software. The VISA example does see the port, but I keep getting a time out warning. I am using LabVIEW 11 and NI VISA 5.1. Am I wasting my time trying to use this example to talk to this card? Thank you, Richard V

How to access to higher address  - Jan 7, 2010

This example is great for using VISA to access at the base address of // port output (0x378h). How it's possible to access to the other output port at the address (0x37Ah) of the // port with VISA structure.
