Q:What is the difference between repeaters and hubs?

The purpose of a hub is to regenerate and reset network signals. Its characteristics are similar to repeaters (referred to as multiport repeaters, multiport, repeater). HUB is a common connection point for each device in a network, which is usually used to connect segments of the LAN. HUB contains multiple ports. When each packet arrives at a port, it is copied to all other ports so that all LAN segments can see all packets. Hubs do not recognize any information patterns in signals, addresses, or data.

Q:Which layer does the repeater run on the OSI model?

The repeater (REPEATER) repeater is the connection device above the network physical layer.

Q:How is the EDUP2930 repeater relay mode set up?

After the signal that connects the repeater is entered in the browser address bar: 192.168.10.1 enters the setup interface;4, enter the user name and password are admin, login successful, select relay mode, to the next step;5, select the name of the router that you need to connect to, and change the name of the repeater to the name you can easily remember;6, enter the original router password, click OK, that is set successfully

Q:My routing repeater, I want to hide my hot spots, hide ssld, show this

It doesn't matter much, because WPS is sometimes not safe and people can run pin code to crack it

Q:RS485 photoelectric isolation relay

RS-485 signal after transmission distance or load device with a certain number of signal strength, will have the corresponding attenuation when the signal attenuation to a certain extent, RS-485 interface chip can detect the corresponding signal, resulting in communication failure.

Q:What does a network node mean? What does a repeater do?. Generally speaking, thank you

The devices that have your own network address are network nodes, such as your company's workstations, servers, your home router, and fax machines.

Q:About repeaters and common twisted pair problems

The function of the repeater is to regenerate and transmit the received signal so as to increase the distance of signal transmission. It is the simplest network interconnection device that connects two or more network segments of the same network.

Q:Is intelligent access control available offline?

1. supply voltage: the use of DC 12V-24V + 10%/2A single supply operation, operating current <100mA (excluding electricity plus electricity driven).2. working environment: temperature: 20~+60 relative humidity: less than or equal to 95% DEG C3. optional password keyboard input.4. can manage 100 thousand user card, offline can store 3000 open records, can store up to 2000 black list, storage records in power down, can guarantee 10 years is not lost.5. contactless IC card read and write time: less than 0.2S.6. contactless IC card read and write distance: 10~100mm, IC Keychain caillaux reduced7. network communication interface: RS485 (standard).8. communication transmission distance: 1.2Km (standard), long-distance communication network.9. appearance size: host L95 * W70 * H25mm.10. scope: attendance, access control, online patrol.

Q:Schneider cool by routing plug can be used as a repeater?

Enter the wireless settings, open the wireless function, open the SSID broadcast, open WDS, click the scan, select the main router needs to bridge the WIFI. And enter the password to save.PS: if there are a lot of WIFI around, it's better to set a good WIFI name so that you can distinguish between them

Q:The role of repeaters?

AP mode (it can be wired to wireless signal conversion signal, for example you directly to the cable broadband network repeater inserted in the mouth, and then plug in relay power socket, this repeater can "release WiFi", you can use the wireless devices, such as mobile phone, flat computer connected WiFi wireless repeater through the Internet WiFi)
