If you use the three wire cable,( XON/XOFF HS) and the VK has a 25pin D connector out to the front then, on the CNC side 6,8,& 20 are jumpered 4 & 5 are jumpered, on the 9pin 1, 4 & 6 and pins 7 & 8 are jumpered the 3 wire connection between D connectors:
CNC -----PC
2---------2
3---------3
7---------5
Set both ends to 9600baud 7 bits, even parity, 1 stop bit.
What communication program are you using?
