  KC868-D8 V4.37 new firmware update
Posted by: admin - 01-06-2022, 12:03 PM - Forum: News - Replies (5)

improvement:

when switch button work in "1 Key" mode . we let the "UP" and "DOWN" button ports with the same function. so that easy for connect two thick wire from two different places. such as this two thick wire not easy connect to one terminal pole.
