Does not work Absolute DVS mode in Rekordbox 4.4 (Serato Time Code Vinyl 2.5)

Friends, please help me figure out the situation. There are two plx 500 vinyl players and a djm250 mk2 with built-in sound. The program Recordbox 4.4. Timecode vinyl Serato 2.5. The problem is this. The absolute mode does not work, when I manually move the needle through timecode vinyl, the track in the program does not move behind the needle. What could be the problem? All connected correctly I can not understand. Is the problem in Timecode Serato?
