After finishing the design and feasibility studies*, we have constructed the new system at Main Trigger Station of Linac. The new functions are developed in this system to perform the injection control of positrons with the newly constructed damping ring. Besides, we integrate the capability to adjust the trigger timing just 20 ms before injection so that the injection RF-bucket of the ring can be decided at the last minute. Now, both the new system and the current working system are operational at Main Trigger Station. This is important for the smooth taking over of Event Timing System. Even during the construction period, Linac must be operated to provide beams into the two light source rings. In this situation, we can carry out enough tests with the actual condition. These tests do not disturb the regular operation and brush up the Event Timing System to enable the quick startup of the SuperKEKB operation. We report about the detailed configuration of the new system and its commissioning performed in the 2014 spring run period.
