  SuperKEKB project aims at world highest luminosity to 8x1035cm-2s-1. To achieve the luminosity, a lot of equipment was newly constructed or upgraded. Especially, Damping Ring (DR) was newly constructed for reducing positron emittance, and was located at the middle of the injector LINAC. The DR timing system was also constructed. The synchronized timing which is generated at injector LINAC, is received at DR sub timing station and is distributed the end of some equipment, Kicker, Septum, and monitoring devices. We succeeded to generate not only synchronized timing but also beam control information such as beam gate for trigger inhibit signal and injection and extraction timing "value" via data buffer delivery. By using this method, accelerator operation became more convenient system.
