LK201s use 4800 baud UART interfacing. PC keyboards with DIN connectors (PS-2) have a very different type of interface, nothing like a UART. If the terminal you are talking about wants a PS-2 keyboard, as my VT501 does, you need a protocol translator. It would essentially be the reverse of the LK201 emulator for PS-2 keyboards I released a while back, and possibly the same board could be used with a rather different program running on it.
