Q:Japanese fire automatic alarm system. How can I dial the repeater?

Now generally electronic dial code, S+S - that is loop bus. Passive contact is an action feedback signal, the need to relay things to 24V, in the 24V jumper to the beginning of the regular. The action of the module is to relay the 24V, and it is cut.

Q:How do the relays connect two routers?

That's all right.The router itself is no problem, you know the network structure is not deep enough.The repeater front only provides a network data signal, so you can only have one signal when you connect the two routes at the same time. Go online and check the router function and the location of the network structure, and you'll see.And what you finally said is the connection method. That really guarantees that all ports on the two routers can go up.

Q:What is radio relay and how to use relay?

As a result of loss, the signal power transmitted on the line will be gradually attenuated, attenuation to a certain extent will cause signal distortion, and this will lead to a reception error. Repeaters are designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. In theory, the use of repeaters is unlimited, and the network can therefore be indefinitely extended. In fact, this is impossible, because the network standards are specific to the delay range of the signal, the repeater can only work effectively within this set of regulations, otherwise it will cause network failure.

Q:What are the WiFi repeaters that can receive signals hundreds of meters away?

A relatively common solution is the use of electric cats, which use electrical wires to transmit network signals, usually sold in pairs. Cat Power earlier do not have dial-up function, and there is no built-in wireless module, and can be used independently, need to use a router, which is inserted in the socket near the router, the router LAN port from a power cable connected to the cat, the other one can be inserted in the signal is not good room. From this a cat can get in touch with the power of a wireless AP or wireless router as a AP signal, it must be full.

Q:What is the performance of wireless WiFi repeaters, wireless relay radio, 150m and 300m?

According to the specific needs and choose to use the above equipment collocation, usually home within 150 square meters can be used 150M router, such as signal coverage to 300 square meters in 200 square meters within the range of optional 300M or 450M wireless router (two or four lines covering high strength), if the room layout called complex or duplex structure, can be covered in the weak signal area additional wireless relay.

Q:TP routers, TP repeaters, but repeaters are always easy to drop. Why is that?

May be disturbed by other people's wireless router, manually designated router WiFi working channel, avoid others

Q:The repeater connects to the wireless network of the left neighbor's home, showing the wireless channel -1, and even the wireless network on the right side shows the wireless channel -6. What does that mean?

Channel is different signal frequency transmission, intelligent routers can automatically adjust, if there is no repeated frequency interference, network speed will be faster

Q:Switches, routers, repeaters, difference?

Routers: routers work in the third layer of the OSI model, the network layer. The router uses the network address defined on the logical layer of the network layer (that is, the IP address) to distinguish the different networks, so as to realize the interconnection and isolation of the network, and maintain the independence of each network. Routers do not forward broadcast messages, while broadcast messages are restricted to their respective networks. The data sent to other networks is sent to the router and forwarded by the router. Switch: LAN switch has many ports, each port has its own dedicated bandwidth, and can connect different network segments. The communication between the ports of the switch is simultaneous and parallel, which greatly improves the throughput of the information. To further improve performance, each port can only connect to one device bridge: the bridge acts on the data link layer of the OSI schema, which identifies the MAC address of the packet. In actual operation, the bridge compares the packet location of the received data to its known network segment address and transfers the data if the packet address is not in the same network segment.

Q:How can I use a wireless repeater where there is no power?

Where there is no power supply, if the wireless repeater is 12V, it can be powered directly by the 12V battery.

Q:What does wireless relay mode mean in routers?

1 、 the wireless relay mode in routers refers to the routing function of shutting down routers, and routers act as repeaters for wireless network signals only.2, router wireless relay mode setting method is as follows,
