Q:In the fire alarm system, when will the relay module be used?

The relay module of different manufacturers of different types of the role is not the same, generally matching the passive contact device constitutes an alarm point (that give an address address encoding equipment, alarm system based on host is through the electrical signal alarm received to control alarm equipment) multi line relay the module is used to control the fire pump, fan and other important equipment, and do the parallel that is used in parallel with a plurality of address free equipment to give these equipment the same address is the address of the module. The above is the common different types of relay module of several functions, the specific role depends on what model, what manufacturers.

Q:How to use a network repeater?

When an isomorphic network segment with the same interface and the same medium access control protocol is interconnected, an instrument device is added in the middle to amplify and retransmit the transmitted signal. Thus, the signal attenuation caused by the long cable line of the network segment can be avoided, and the reliability of the transmission can be effectively improved.

Q:Is the wireless repeater power cut all right?

In order to extend the coverage of the wireless network, the repeater can simply regenerate the signal. Repeaters do not need to physically connect to any part of the network via cables.Therefore, the wireless repeater is an effective solution to the problem of signal damage, attenuation and so on. For example, a repeater provides a connection that reaches the remote range, which does not have access to the wireless network. Perhaps the router in your home or office does not cover the entire range of wireless users that need to be connected, such as a yard or basement. Placing a repeater between coverage and non coverage ranges provides connectivity within the full space range. Because wireless repeaters add holes to coverage.

Q:Can the WiFi signals that are expanded by repeaters use the network set-top boxes?

The wireless broadband network you connect to has the same effect as the one you use to connect your home and will not be affected.

Q:The net line is about 200 meters, and there is a repeater in the middle. Can we use it?

Repeaters are available, but they are rare. Wiring is more than 100 meters. It should be poorly designed. The central switch can be used. The hub is useless.

Q:Why do home networks typically use routers? Repeaters, bridges, and the like? What is the name of a direct link modem for a network?

Bridge: like a smart repeater. Repeaters receive signals from a network cable, amplify them and send them to the next cable. Bridges, by contrast, are more sensitive to the information uploaded from the checkpoint. A bridge is a technique for forwarding frames, isolating collisions according to the MAC partition block. The bridge connects multiple segments of the network at the data link layer.

Q:Can routers be plugged in after the relay is successful?

Wireless router wireless relay received signal and WAN port connection network is the same, can be directly through the LAN port of the network for computer use.

Q:Which is good for a WiFi repeater?

Mainly to see if the link is stable and the repeater signal loss, repeater principle is that they will send a signal, when the connection after landing back switching relay mode (some more than repeaters used to relay) can find its own routing signal emission in the WiFi list, after the connection (to be renamed) to achieve the forwarding of the original signal in order to achieve, to enhance the signal propagation.

Q:How does the COMFAST wireless relay router use the relay function (model CF, wR360N)?

To set up WiFi wireless relay, first need to ensure the wireless router relay is normal network, in order to facilitate understanding, we sometimes also known as a wireless router to the relay router or relay signal, and we want to set up a wireless relay router is called the wireless router or wireless repeater, to show the difference, don't confuse oh.The use of mobile phone or computer to be relayed to the wireless router, wireless router to the TP-LINK for example, enter the router settings page, view the running state of the router, the router has to ensure network, if the router does not relay network, the wireless Internet is not in the following.

Q:The role of repeaters in Ethernet?

For example, a high level may be parsed low, so it is necessary to amplify the signal before it decays so as to increase the transmission distance!In short, the main function of repeaters is to resend or forward data. Amplify the signal and increase its transmission distance.
