因此,EIA485可以看作是这一标准在EIA体系下的命名。 RS485:这一命名则来源于英国的电信行业协会(Radiocommunications Agency,简称RA),后来演变为现在的RS(Recommended Standard)命名体系。RS485即表示这是RA推荐的第485号标准。随着时间的推移,RS命名体系在全球范围内被广泛接受和使用,因此RS485也成为了这一标准的更...
Otherwise, since EIA 485 is a standard, devices that claim to use this protocol should require the following wiring to achieve full communication (also reference the embedded image of a schematic): Pins 5 and 9 of the DB 9 Male connection should be jumpered together and wired to terminal A...
The RS-485 and RS-422 standards share many of the same attributes, and are often confused for that reason. The table below compares the different standards. The RS-485, which specifies bi-directional and half-duplex data transmission, is the only EIA/TIA standard that allows multiple receivers...
A communication module is disclosed for Intelligent Electronic Devices (IEDs) which can implement the EIA-485 standard, including an intelligent hardware support that can allow a known software-based collision detection function to detect collisions independently of the location of the message sources on...

The EIA-485 standard is misunderstood to mean more than what it defines. According to the standard it specifies the characteristics of the generators and receivers used in a digital multipoint system. It does not specify other c haracteristics such as signal quality, timing, protocol, pin ...
本工程出版物提供了应用符合 TIA/EIA-485-A@(以下简称 485@)的电路形成平衡多点数据总线的指南。 485 电气标准的多功能性涵盖了本出版物无法涵盖的各种数据交换应用。目的是提供物理层的基本设计指南。在应用 485@ 中定义的驱动程序和接收器时,读者应牢记几个重要的注意事项。首先要考虑的是系统的实际配置,包括驱...
This chapter focuses on Electronic Industries Alliance (EIA)-485 standard and its features. The EIA-485A standard is one of the most versatile of the EIA interface standards. It is an extension of EIA-422 and allows the same distance and data speed but increases the number of transmitters an...
