Whelen Liberty won't sync.

[yomusic]

I have a Whelen Liberty lightbar. I can't sync the pattern in the video. I have disconnected the AUX cable. With the AUX cable connected I only can choose from 8 patterns. And those patterns are horrible. The print plate has the # P/N 01-0269879-00A LC Liberty.

Thanks for any reply,

Johan

Example of one of the patterns

Is it a wecan bar? Can't sync old school Liberty bars. Only alternating pairs will sync.

There is mod where you can alternate side to side though by adding power to one of the pins on the IO board.

I red that and they mean the AUX on the I/O board. Put a + on it but then I get the 8 patterns I already have. Using another I/O board will help ? It's not a wecan

The mod works on the non wecan boards. I'm not sure which pin it is but when activated, the bar alternates side to side. Not sure how many patterns but it won't look like your video if done correctly.
