Orders of 2 or more will receive a free gift.Ethernet splitter contor Usage: (1) Use a single adapter : It can be used as ethernet cable extender, but only port 1 available to be used. (2) Use a pair of adapter: One network can be divided into two, enabling two devices online at the same time. Reference product display picture,Product contains instructions for use.^ Working principle: net splitter adapter is to devide one original pre-embedded network cable (8 cores) into two groups(1236/4578), respectively, transmit date. Lan splitter is purely physical contion, and does not have the function of assigning IP address, also not with the router or switch. Two groups signal transmission do not fere with each other. A pairs must be used when installing.^ Stable transmission: The network splitter ethernet built-in thi environmental protection PCB circuit board, RJ45 eight-core standard ja, gold-plated pin core, integrated mechanical welding, more stable transmission signal, superior contact and transmission performance, ensure signal transmission, durable.^ Safety and stability: environmental protection and flame retardant ABS plastic shell, fixed RJ45 f, 8 TVS gas discharge tube lightning protection technology, shielding electromagnetic ference, preventing network signal loss or damage. RJ45 splitter contor can also safely use the network during thunderstorms. Ethernet cable splitter meets the performance requirements of 5 / 5e / 6 / 7 network cables.^ Precautions: RJ45 splitter adapter is to resoe contion problem caused by insufficient cords,through the physical tap way contion to aeve network split in half so that enables two devices online at the same time, plug and play, and don't need to set. This ethernet spiltter adapter is different from 1 to 3 network splitter, as 1 to 3 one can't allow two devices to be online at the same time.
