The standard parallel port is capable of sending 50 to 100 kilobytes of data per second. A pin is either a '0' or '1'.Īll pins can transmit information simultaneously in parallel as apposed to serially (one by
Parallel port Pc#
The CONTROL port was mean to output control information to the printer and the STATUS pins were inputs back from the printer to the PC meant to communicate things like 'out of paper', etc.Įach pin is used to literally communicate 1 bit of information. The DATA pins are meant for input and output of data (typically this was to send the printer the information toīe printed). The three sets are DATA (in/out), CONTROL (out) and STATUS(in). The Parallel Port pins are divided into three groups of pins mean for difference purposes. An external parallel port is much cheaper to replace than NOTE that if you are experimenting with newĬircuits you may want to purchase an external parallel port in case your wiring may The Parallel Port is an inexpensive way to communicate to external TTL 0-5V devices using your PC's parallel port. The following is a brief discussion on the parallel port pins and its potential use. If you continue to experience problems contact DATAQ support for further assistance.The Parallel Port module allows you to use RoboRealm to control the parallel port pins based on RoboRealm variables. Note: Once the loader and WinDaq are working the fictitious printer may be deleted.
Parallel port windows#
Double-click on "Printers and Faxes" in the Windows "Control Panel".
Parallel port driver#
The PARPORT.SYS driver must be installed to run these products. Verify that the PARPORT.SYS driver is installed Did WinDaq start properly? If not proceed to the next step. Consult with your IT department to verify that your parallel port is configured as EPP or Bi-directional.
The parallel port mode is set in the PC BIOS. DATAQ Instruments parallel port products do not support ECP parallel port mode. In order to communicate properly your parallel port must be in EPP or Bi-directional mode (the Standard printer port mode is supported by all -P suffix products). Verify that your parallel port is configured properly If you are using a replacement (not provided with the unit), verify that "IEEE 1284" is printed on the cable. Verify that you are using a compatible parallel cableĭATAQ Instruments parallel port products require the use of an IEEE 1284 parallel cable. To resolve these issues follow the steps below. The PARPORT.SYS driver is not installed Resolution The parallel port is not configured properly This could be the result of one or more of the following:
Parallel port series#
"DI-500/720/730 series driver not installed" Cause The WinDaq title bar displays "DI-000 Acquisition" or "DI-? Acquisition" While attempting to run WinDaq for your parallel port data acquisition device you encounter one of the following issues/messages: Verify that you are using a compatible parallel cable Parallel Port Issues (Windows 2000 and XP)
