Losing buttons when restarting system

Denis

Hi

I installed an DASM0808 system controled trough TP and DMS keypads. My problem is when I restarting system or after an outage power, I losing sources buttons on TP ( channel controls, volume controls etc..) and Matrix feedbacks (vol level etc..) on any MDS Keypads. IIf I disconnect physically a TP I retreive all buttons and feedbacks.

I use DAS Matrix module, NI3100,NXD500i and DMS keypads

Any cue?
