How to control LPT Pin15(Status)

[Asuka]

hello everbody!

I'm trying to control LPT pin15 on/off.
But I Don't know how.
To control Status Pin is  quite different from to control data Pins(2-9pin)??
Please help me...I  want to fix this prolem as soon as I can.

In the fllowing I showed the register of each pin.
Data pin : 2,3,4,5,6,7,8,9
Status pin : 10,11,12,13,15
Control pin : 1,14,16,17

Any idea would be greatly apreciated!
Any way Thank you i Advance.

Pin 15 is an input to the parallel port so you won't be able to control it using LabVIEW. You will need to control this in hardware from whatever you are connecting to LPT1, using +5V TTL logic.  A quick Google found details on parallel port connections HERE http://www.interfacebus.com/Design_Connector_Parallel_PC_Port.html

I hope this helps you.

if you need more control pin ,you can use EPP mode which can be modified in BIOS. PIN2-9 can be Bi-direct of input and output.

If you look in the LabVIEW examples for "parallel port access" there is a sample vi that should help you.

[gaogonghm]

EPP mode  pin 2-9 can be IN or OUT at what you choice.  in the file paste, 读并口.vi and 写并口.vi  I wrote just in chinese, I think you of course can understand. 

  fisrt  you must change the LTP mode in BIOS when you start the PC, change it to EPP.
the first run 写并口.vi   ,there is a 读控制 control in it , if it is ture then 2-9 is read only , if false pin 2-9 is write only.

 if you have any more Q you can mail me gaogong@sina.com or gaogonghm@google.com
