Q: RS485 photoelectric isolation relay: The 485 repeater is located in the 485 signal attenuation but also can detect the location of the signal, the 485 signal shaping in the reduction, copy the signal through the RS-485 bus transmission, so as to extend the communication distance of RS-485 bus, RS-485 bus to increase the load capacity of the role.

Q: How to set up wireless relay: First, enter the router management interface - Advanced Settings - wireless networks - basic settings (remember the router's wireless channel, network name (SSID));Secondly, wireless networks - Security and encryption (remember the router's security model, encryption algorithm, shared key (password))Again, the wireless network - WDS settings (remember the router's WDS mode - select self learning mode)Finally, the network settings - LAN (remember the router: IP address, DHCP server type), so the master router setup is complete, if the main route of normal use, does not need to change the settings, but to write down the above parameters with the reserve.

Q: What is the function of relaying?: A repeater is a network device, a physical layer device for the regeneration and reduction of signals, and a OSI model.

Q: WIFI how does the repeater amplify the amplified signal?: The realization method of wireless relay is to increase wireless devices, by the relay to the host device to transmit signals, the increase of transmission distance, intermediate relay equipment after more mobile terms called micro cellular system, because no routing relay equipment and DHCP and other more than three layers, is also transparent to users. Is that users feel like intermediate relay equipment, or connect to the same device, through the relay to amplify the signal distance, avoid attenuation.

Q: Which is good, wireless relay or routing WDS?: Wireless relay can be interpreted as a special WDS: SSID and wireless connection, password and encryption the same as the main router WDS, in essence, there is no difference between the two.The above bridge router is wireless, and the transmission medium is radio wave, which is greatly affected by the wall. Generally, the 2 wall signals are lost.

Q: Is it possible to relay a repeater after a wireless router?: First, router relay is possible,

Q: What is the repeater used for?: Repeaters (Repeater) work at the physical layer of the OSI, the center of all nodes on the LAN, which amplifies signals, compensates for signal attenuation, and supports remote communications. Repeaters are a small invention designed to push your network signals so that they can be transmitted farther. It's like a drink stand in a marathon. When the signal passes through a repeater, the network signal picked up a cup of drink, drink, the rest of the poured into his head, throw away cups, if convinced that no one saw them, jumped on a car. Due to the effect of transmission line noise, carrying digital signal or analog signal can transmit information in a limited distance, repeater function is regenerated and sending the received signal, thereby increasing the signal transmission distance. It is the most [1] simple network interconnection device, connecting two or more network segments of the same network. If the length of the cable Ethernet Repeater often use bus standard, thinnet each maximum length of 185 meters, up to 5, thus increasing the repeater, the maximum length of the cable network can be increased to 925 meters. In general, the network at both ends of the relay is a network segment rather than a subnet. Repeaters can connect two LAN cables, re - timing and regenerating digital signals on the cables, and then send them, which are typical functions of the first layer, physical layer, in the OSI model. The effect of relay is to increase the coverage area, such as Ethernet LAN [2], the maximum length of standard single signal transmission cable is 500 meters, but using the repeater cable to connect 4, Ethernet signal transmission cable up to 2000 meters. Some brands of repeaters can connect cable segments of different physical media, such as thin coax cables and fiber optic cables. The repeater sends only data from any cable segment to another cable, regardless of whether the data has erroneous data or is not suitable for the data of the segment.

Q: Are there any differences between the WiFi receiver, routing, signal amplifier, repeater and signal intensifier?: Signal amplifier is to increase the equipment, so that the original signal difference in the local signal enhancement.A repeater is a device that allows signals to extend.

Q: How does ZigBee implement the routing relay function?: For example, with FastZigBee protocol, to ensure AB two terminal configuration can make two normal communication, in the distance is too far away to do communication, as long as the AB into the middle of the routing node, you can return to normal communication points, other configuration does not need to be modified.
