... ☛This adapter one end RJ45 male can only be inserted in the computer's RJ45 network jack, the other end USB2.0 female connected to a USB port of the dialer or router, the rj45 male to usb2.0 female adapter can be used when the USB cable cable for edge An ADSL modem or USB interface with a USB port..
☛It can be used to connect a USB ADSL modem to a router with an RJ45 socket, but please note: you need a PoE data switch.and Note: This adapter can not be USB2.0 plug in one other USB interface device, the other end connected to the computer's RJ45 interface, it will not work,Does not work for USB 1.1 (Printer style USB).
☛RJ45 Male to USB AF Adapter for network,Easily connect and transfer data between networks with this USB female to RJ45 male Ethernet adapter(you need a PoE data switch).
☛Equipment used: 1. Have the operating system of the machine: such as a USB interface with a wireless ADSL dialer and router, monitoring dedicated USB interface, a network transmission function of the camera (not connected to the computer network video chat that kind of camera ).2. Don....

SinLoon Ethernet splitter Specially idear for Solve theNetwork wifi signal weak and connection problem caused by insufficient wiring: such as the basement, the attic, the remote house, 2 or more devices online.
the 1-pair rj45 8P8C LAN Ethernet Splitter connector is compatible with Cat 7 Cat6 Cat5 Cat5e Network Ethernet Cable and can compatible with ADSL, hubs, switch, TV, set-top box, router, wireless device, computer,etc..
Please follow the images instructions to use a pair of RJ45 Splitter Coupler at the same time.The speed of each cable groups (1 and 2) can only reach 100 megabytes.And the signal transmission of two cable groups are not interfered with each other.RJ45-A interface port"1" is corresponding to RJ45-B interface port"1".RJ45-A interface port"2" is corresponding to RJ45-B interface port"2".They can't be reversed..
The adapter divide original embedded Ethernet cables (8pins) into two groups (1236/4578). Two groups respectively transmit data with purely physical connection which don't have the function of the assign IP addresses..
This adapter is not the same as a network router or network switch without the function of the assign IP addresses..

Computer debugging USB--TTL. This module is powered by: 5V-26V, 5V 2A power supply is recommended. After plugging in the motherboard, the power supply must be able to supply 2A. The reason is that the GPRS Shield startup current and the maximum top current required to work up to 2A, but the USB port can not provide such a large current, so the external power supply equipment must be provided..
The other power supply port leads to the 3.7--4.5V power supply for lithium battery power supply. The serial port is perfectly compatible. The TTL serial port is compatible with 3.3 and 5V microcontrollers..
Make sure your SIM card is not locked. The best baud rate for GPRS Shield communication is 19200 BPS 8-n-1 (GPRS Shield automatically matches baud rate by default). Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all countries across the world..
