DJM-2000 NEXUS and CONTROL VINYLE

Good afternoon! There is djm 2000nexus.

1) I want to play a timecode with the Technics SL-1200 MK3, do I need an additional sound card or does it recognize the timecode when connected to the recordbox?

2) how to connect it? let's say the first channel is vinyl, 2 other cdj? how to specify in the program that the vinyl was like a time code

3) my recordbox version is 5.8.7 is it enough for me to buy only the RB-VS1-K timecode

p.s.

sorry for my english)
