AB - SuperKEKB is the upgrade of KEKB, which is the world's largest luminosity accelerator at KEK. One of key items to realize 40 times larger luminosity than that of KEKB is damping ring (DR) for positron injection. The injector linac (LINAC) once stores the produced positrons into DR and suppress their emittance. Then low emittance positrons are extracted from DR and injected into the main ring. For this complicated injection process, the Event Timing System* for LINAC** was upgraded and its soundness is demonstrated by injecting electrons into two light source rings***. New Event modules were also installed under the Event network for LINAC as the sub timing system for DR. New Event modules were developed which can be operated with the different Event clock from that of upstream modules. It solves the difference in RF frequency between LINAC (2856MHz) and DR (509MHz). This sub timing system can manage the triggers towards totally 84 BPMs at DR although it consists of only 5 Event modules. The timing of those triggers can be independently set in more precise than 100ps. The requirements to DR timing system and the newly developed modules with its configuration at DR are explained.
