Upon looking at the various pages you referred to, it appears that they have made the proper adaptor for use with the K2. You would, however, need the KIO2 for this to work. Elecraft does not recommend a direct connection to the /K2 TX, /K2 RX lines as this could cause problems.
As to the other questions, IF you have the KIO2, the KIO2 will interface WITH the Recommended adapter cable to a PC and uses +/- 15 (approximately) volt signals on pins 2/3 with 5 as common/signal ground (standard PC I/O). ALL other pins must have no connection!!! (or you will brake the K2 and possibly the K2 MCU. For most S/W to talk to the K2 it is assumed that pins 7 and 8 are tied together at the cable. I would address your questions to WWW Lynovation Com and ask them what is needed.
