DMX realy kit k8072 problem

Kit works ok but with one issue.
If power lost or interrupted to board, then DMX control is lost!
Once power to board reinstated then DMX must then be stopped and started again to regain control.
I need to turn power off and on to board without stopping DMX, any solutions please?

Did you try different setting of JP2, as explained on page 12 of manual ?
If this does not work, then we are afraid that there is no other way of making it behave as you would like it to behave.

Thanks for your help, yes I have tried different jumper settings as per manual, my problem still remains.
My best guess if there is no easy on board fix I will install a small drop out replay to interrupt dmx until relay board fired up.
