Footnotes: *1 If the response time (ON to OFF) exceeds 20 ms, this unit cannot be used as a certified product based on the Chinese standard GB 4584 ????????????????. * When the GL-S units are connected in series, the response time is calculated according to the following steps; 1. Sum up the response time of all unit. 2. Subtract the following time from the result of previous step. - ON?OFF One sub unit connected: 2 ms Two sub units connected: 4.2 ms (When using Optical synchronization system and Channel A or B) One sub unit connected: 2.7 ms Two sub units connected: 5.7 ms - OFF?ON One sub unit connected: 42 ms Two sub units connected: 84 ms *2 If the response time (ON to OFF) exceeds 20 ms, this unit cannot be used as a certified product based on the Chinese standard GB 4584 ????????????????. * When the GL-S units are connected in series, the response time is calculated according to the following steps; 1.
