ParDoor

Description

ParDoor is a Windows XP / 2000 / NT device driver for the K-2805 Parallel Port Interface available from Dick Smith Electronics. The ParDoor companion application allows complete access to all features of the board, including kilohertz sampling saved to files.

K-2805 Parallel Port Interface

  • Connects to a parallel centronics printer port on your computer.
  • Able to sense data, process it and use the results to control relays, motors, solenoids etc.
  • Can monitor 10 analogue voltages.
  • Drive 8 digital outputs.
  • Generates 2 variable voltages.
  • Requires a 9 volt battery or DC supply.
  • Supplied with components, PCB and 25 pin "D" type connector.

This can be ordered through Dick Smith Electronics' web site www.dse.com.au.

How To Use

  • Install the ParDoor device driver and then execute the ParDoor application.
  • The combo box in the top left corner lets you select the parallel port to which the K-2805 is connected.
  • Check "Power" and then click on the "Input / Output" button to turn on the K-2805's power.
  • By selecting the various check boxes and clicking on the "Input / Output" button, the state of the K-2805 changes.
  • "Analog Outputs" allows you to choose the output voltage from 'Out 0' and 'Out 1' by a value between 0 and 255 or by the voltage between 0 and 5. You must enable the outputs to generate the voltage.
  • "Digital Outputs" allows you to choose which open collectors to switch. It must be enabled to have effect.
  • "Analog Inputs" allows you to choose which voltages to read. They are displayed as 0 to 255 values as well as 0 to 5 voltages. Except for "Get Battery" which displays the external voltage and "Get Test" which should be 128 +/- 2.
  • By clicking on the "Sample.." button you arrive at a new dialog box.
    • Before sampling please turn on the K-2805's power as described above.
    • Select a input to sample in "Analog Input", the number of samples to take and optionally, an extra delay between samples.
    • The results of the sampling can be formatted as tab delimited, comma delimited or space delimited, and output to a file and/or clipboard. "Open in Notepad" opens the saved file in notepad after sampling. Please, if you select "Save to file" always enter a filename or use the browse button.
    • Once the above options are selected, click on the "Sample" button.
    • The bottom of the dialog box is updated to show the number of microseconds per sample, the sample frequency and the total time taken to do the sampling. I have achieved a sample frequency of 16.5 kHz on my computer (90MHz Pentium).
    • By changing the "Extra delay per sample", you can change the sample rate. It is not recommended to use values greater than 50.
