RS485 wiring can be arbitrary layout into star connection with tree, 485 wiring specification is the wiring must be hand in hand, when there is no use 485 hub and 485 relay setting directly into the star connection and connection in a tree, it is easy to cause reflection bus no. Many contractor in 485 wiring, use of star connection and tree, sometimes the very, but sometimes is always appear problem, and it is difficult to find the reason, is usually caused by non-standard wiring. If star connection or tree connection is required due to field connection, the 485 hub and 485 relay of shenzhen fuyongtong technology co., LTD can be used to solve related problems.

With the same negative level transmission, when in the light, their impact on the two wires are the same, thus reducing difference at the receiving end can block this (minus operation performed can be understood as a difference of two way). It can be seen from the principle of double stranded lines that the purpose of double stranded lines is to transmit. Therefore, when we make the joint of the twisted pair, we must not separate the two different transmission lines, otherwise it will greatly affect the transmission of the network.

今天简单讲一下，自保持互锁电路，先看一下电路图，功能介绍一个停止按钮，两个启动按钮，以先动作的信号优先另一信号因受联锁作用，在停止信号未动作前用不会动作。当先按下常开按钮1，J0动作J0常开触点闭合J0自锁,J0常闭触点断开,同时锁定J1不能接通这时按下常开按钮2，J1也不会动作，这就是自保持互锁，若有J1动作，必须先停掉J0,要J0失电(按下常闭按钮0，使电路恢复初始状态），再按下常开按钮2，J1才会动作,同时J1常开触点闭合同时自锁，J1常闭触点断开，同时锁定J0不能接通。

千兆网线一般情况下，Cat6六类网线的传输速率为1000Mbps，而Cat6a超六类及以上的网线的传输速率超过10Gbps,因此将Cat6六类网线称为千兆网线。百兆网线通常Cat5e超五类网线的主要传输速率为100Mbps~1000Mbps之间，在特定的条件下也可用于千兆传输，但是效果不好，而Cat5五类网线主要传输速率为100Mbps，因此将Cat5e超五类网线与Cat5五类网线称为百兆网线。但实际上我们需要知道，网线规格保证的是电气传输性能，而不是网速，实际网速不仅跟网线有关，而且跟终端设备有很大关系。
