Hi,
Joining in on this past conversation. I have such keyboard that I am trying to make work on a windows PC, but of model LK250-aa, which based on the 6p6c cable photos as posted on the original post by Shmex, appears to be the same model as his. I nonetheless built a Cable with ps2 outlet plugged into a Soarer’s converter, with pinout as described by WRS80913 (but as he mentions, his keyboard is LK250, not LK250-aa).
What I get when I plug it into the PC with such a cable, is that the keyboard makes a kind of boot noise, and then the “special” LED is on. I can switch on/off special LED with ALT+F17 and when I type I hear beeper sound for each key pressed (internal beeper function of this terminal keyboard?). So it seems voltage reaches the keyboard appropriately, but data does not reach the PC, as when I type, no character registers. I am wondering if I maybe only have partially correct pin-out for the LK250-aa. Is ti possible it uses 1 and/or 6 position of the 6 wire cables, and so is different pinout than LK250? I can’t find any pinout info on LK250-aa anywhere?
Cheers
