Currently, SuperKEK has network-based systems such as trigger delivery, bucket selection, abort system, beam permission, and distributed DAQ, all of which are operated as separate systems. The White Rabbit (WR) has extraordinary multi-functionality when combined with the modules already developed, so it is possible that in the future all systems could be operated in a WR network. This would lead to a reduction in human, time, and financial costs. We constructed a beam gate, which is a part of the beam permission system, on a trial basis using WR. These trigger deliveries need to be interlocked. The trigger delivery to the electron gun has a specification that the next trigger delivery is turned ON/OFF after receiving the ON/OFF signal at any given timing. For the above reasons, the delay time from the receipt of the ON/OFF signal from the electron gun is not a fixed value, making it difficult to interlock with the trigger delivery of other devices. By turning on/off the trigger delivery using a precisely time-synchronized WR, the ON/OFF of the trigger delivery of all devices could be correctly interlocked.
