Q:Broadband lines over 300 meters. Can I use repeaters?
As far as your network line condition is concerned. It can be said that five types of network cannot be installed. The distance of 300 meters is really too far away. As for the use of repeaters. Indeed, the distance to extend the signal transmission can be limited. You have to think about a lot of problems. For example: to relay equipment installation problems, power supply problems, lightning protection issues, security issues, and so on.
Q:What are the functions and principles of repeaters?
Principle: when the relay coil is applied to the required voltage, the armature is sucked into the guide magnet, and the armature presses the contact spring fragment to make the contact switch on, disconnect or switch the controlled circuit. When the coil voltage of the relay is broken, the armature and contact piece return to their original position.
Q:Android phones do wireless relay, how can I do that?
If you do need to use mobile phone relay can, but need a mobile phone wireless module supports WDS function, which we call two WiFi wireless connectivity, a WiFi connection next door, when a hot to provide their own home. But mobile phones with this function are few and far from practical, because the cell phone's transmitting and receiving function is very small, and the battery power is also consuming rapidly.
Q:About the use of RS485 repeaters?
Signals at both ends should be isolated and amplified, after all, bidirectional transmission. 4., I have tried 2 kinds of connection, the effect is similar, my network from the station more and interference, should be no problem. But habits make progress.
Q:How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?
Enter the router to see the name of the wireless network. Or customize an easy to remember wireless network name (preferably not in Chinese). Then the wireless Internet settings, such as mobile phone, open WIFI, to manually enter the wireless network name, you can find the wireless network, and then select the corresponding wireless encryption protocol, such as WPA2, the right input wireless key, can be connected to the Internet router.
Q:Schneider cool by routing plug can be used as a repeater?
Can be used as a repeater.After entering the router management page, in the network parameter -LAN port settings, modify the IP and the main router is different. Restart after save.
Q:Why are radio repeaters different in frequency and frequency of reception?
Your so-called magnification is wrong, for example I use hand 1 watt transmitter, relay station after receiving the will with high power is transmitted, but the size of power is set by the relay station maintenance, usually about 25 watts.
Q:Does the use of a higher router as a relay affect the network speed?
This is only within a certain range and may not be very effective (not very much).
Q:What is the use of the relay module in the fire fighting weak electricity system?
The technical parameters of the current relay module are as follows:(1) the quiescent current is less than 20mA.(2) load carrying capacity and compatibility: it can be equipped with 1~242 point bus equipment and compatible with all bus equipment.(3): bus isolation voltage input and output bus isolation voltage of more than 1500V.(4) the use of the environment: temperature: -10 to +50 DEG C relative humidity is less than 95%, no condensation.(5) dimensions: 85mm * 128mm * 56mm.
Q:What's the function of repeaters in fire fighting engineering?
When the faulty part of the bus is repaired, the isolator can work itself back, and the isolated part is re incorporated into the system. The relay module is installed at the front end of each branch circuit of the two bus circuit and will be automatically disconnected when the branch circuit is short circuited.
