I used manual at http://www.mameworld.net/tigerheli/encoder...kker/index.htmlLpt-reloader i downloaded from avsim.com But it doesnt work or report this error: http://i76.photobucket.com/albums/j40/timberl/1-3.jpgI cheked wiring, black strip of diodes is in the right direction. In BIOS i don't have option for SPP, but i have Output only/bi-directional/epp/ecp so i put bi-directional. Is the same like SPP?If i open notebook and press TEST in lpt-reloader i got this"'vnfwogxphyqia!zr&sktld"ume-'vnfwogxphyqia!zr&sktld"ume-'vnfwogxph..." until i pressing stop.Please help me

one more question. Is it some difference if i put diodes like B, or i have to connect only like A? (see the picture)http://i76.photobucket.com/albums/j40/timberl/diod.jpg

as a reply to your last question:A is the same as B

Thank you for answer!In ini file i wrote to all 40 buttons "Pa", so when i do TEST in LPT-reloader i get 40 "a" in notepad per second, its look like "aaaaa....."I solder 3 pushbutton to the matrix-tower, but they dont respond if i try to type "A"What can be a problem?

Cathode or anode must be connected to button's side in matrix tower?

if you know what cathode and anode are, then you can surely read this:http://www.mameworld.net/tigerheli/encoder...LPTswitch07.jpgShould explain it all :)

it's not explain, im sorry..i tried both ways with diodes, but it's not work.May be you know, SPP is the same like Bi-directional in BIOS?
