1、Establish Communication: RF communication, mainly used for communication between the communication bridge and the slave, the communication bridge through the 443Mhz radio frequency to send and receive data, the slave and the communication bridge in the same communication frequency, then the two can establish communication between them. 2、Working Principle: For communication between a bridge and multiple slaves, the communication bridge will establish a 10 minute long queue, assign a serial number and communication time to each slave, communicate with different slaves at different time periods, and recalibrate the time every 10 communication queues and slaves to avoid communication errors. 3、Serial Communication: Mainly used between the communication bridge and the PC, standard serial communication, fast and stable. If the PC and the communication bridge are not in the same network segment, you need to let the PC connect directly to the device, modify the device IP and gateway, and then let the device connect to the network. 4、Network Communication: Mainly used between the communication bridge and PC, standard TCP IP communication, no need to use wire connection, large range, flexible and convenient. 5、ABS Material: WiFi to ethernet adapter is made of ABS material, wear resistant and durable, not easy to damage, can be used for a long time. Item Type: RF Wireless Bridge Material: ABS Default Web Address: 192.168.4.188:5200 User Name: COMbridge Password: 8888888888 Support: TCP/IP Protocol Support: 802.11g WiFi Protocol How to Use: 1.Connect the slave, long press the add button (ADD) or click the add button on the software, the communication bridge will enter the add mode, the indicator light will always be blue. Bridge will enter the add mode and the indicator light will always be blue, then press and hold the slave button until the slave indicator light flashes green continuously. If you enter the add mode from the software, the software will show the current number of slaves plus 1. If there are more than one slave to be added, repeat the slave action. After all slaves are added, if you enter add mode from the software, click Add to finish. After all the slaves are added, if you enter the add mode from the software, click Add to finish, if you press and hold Add, then press the Add button again, and the blue light that is always on will go off.Note: If you have added a slave and do not need to use it, please power off the slave to avoid repeating communication 2.There are two ways to connect the PC, one is serial connection and the other is network connection. If you use serial connection, use the serial cable to connect RS232 interface, if If there is no RS232 interface, you can use a serial to USB device to connect to the USB. If using a network connection, you can use either a direct network cable connection or a WiFi connection. See the last page for details of WiFi connection. 3.Indicator light function, green flashing, the device belongs to normal operation; the device is always on blue light, which means the device is in slave add mode; the device is in slave add mode. The red light is blinking, representing the device received slave data; if the device is powered on, the device light is not on, the device is not connected. If the device light does not light up after power on, it means the device is malfunctioning, reconnect the power or check whether the power is normal. 4. To restart the device, press and hold the restart button (RESET) until the red, green and blue lights flash at the same time, the device reboots successfully. After the device reboots, all slave information will be cleared and the device information will be initialized. 1 x Communication Bridge 1 x Antenna 1 x Adapter Cable 1 x Data Cable 1 x Power Adapter
