Q:What's the role of the DMX repeater?

A RS-485 network sharing 2202R allows the baud rate and data format of various equipment, through the built-in intelligent control circuit (Turbo-Turning), can automatically detect baud rate and data format, and data flow control RS-485 accurate, not only reduces the overhead of the system, but also greatly enhanced the reliability of the system.

Q:How can there be a walkie talkie in the absence of walkie talkies and repeaters? 30KM. My friend succeeded and didn't know how to set it up.

At present the intercom far more than 10 km far or in no obstacles or ideal conditions can have, you said thirty KM theory is not possible, unless he is using a digital radio base station into the network, then the conditional can interphone, there may be he cheated on you he used the relay station did not say with you,

Q:The role of field bus PROFIBUS DP/FMS isolation repeater is also discussed

The industrial design of PROFIBUS optical fiber communication repeater and DP/FMS bus signal isolation and data communication, with the total line photoelectric isolation, signal regeneration, extend the transmission distance, increase the number of nodes and other functions.

Q:What does WIFI relay mean?

WiFi repeaters are wireless routers with trunking capabilities.

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

Radio relay is a high power type transponder.

Q:Does the network repeater radiate in the bedroom?

It is better not to put the WiFi device in the bedroom, especially at the bedside. If you don't use WiFi, you'd better turn off the wireless router to reduce unnecessary risks.

Q:What is the walkie talkie relay station?

Radio relay station is used to increase the distance of the radio communication equipment, when two walkie talkie over a distance range of radiation radio signals, walkie talkie will not receive effective signal, then you must use the walkie talkie relay station. The function of the relay station is to forward the received signal and complete the relay between the signals.

Q:How to make idle routers at home used as relay stations?

No need, one router, more than one fault node, the problem of maintenance is more troublesome.

Q:What are the differences between routers, trunks, and bridges?

Bridging refers to the process of forwarding network packets according to the address of the link layer of the OSI network model, working on the second layer of the OSI. A general switch bridges the bridge.

Q:Can the wireless repeater amplify the signal output by wire?

Repeater mode: wireless access to existing wireless networks, equivalent to wireless switches. In this mode, AP to SSID and the same channel and the existing wireless network; WISP client mode: WISP is a wireless network service provider, in this mode, the AP as a NAT router, a cable network (connected to the AP LAN port) to access the wireless network and wired network, DHCP WISP; repeater mode: provides wireless users access, NAT and DHCP based on client mode WISP.
