In my store we have the "newer" compression type 6 position J boxes for ultradomes.

I made an attempt at connecting a speed dome to an ultra dome 6 position j box and got picture and power, but the data is not working. Has anyone attempted this? I know how to convert and ultra dome to a speed dome 10 position j box, but not a speed dome to the ultra dome box. I have followed every direction I have with no luck.

Any help would be appreciated.
