for a certain No. ranging from 0-F, a total of 16 options. which means our
product could set 16 isolated LANs in the same area. WiFi-104 will initialize
with a run LED indicator flashing about 25s quickly, each time the SSID NO. is
changed. Mobile devices need to search and connect to WiFi again after
Initialization is finished.
