485集线器HUB产品功能及应用介绍！485是一款4口光隔RS-485/422总线分割集中器，实现232/485转换器、RS-232/422双向转换及RS-485/422中继功能，一路进4路出。
集线器是一款专为解决复杂通信环境下485大型系统总线形式要求而设计的485HUB总线集线器。
可以提供更加灵活的RS-485星型总线结构RS-485接口输入、输出端均采用独立驱动方式，改变原有总线的单一式结构为星型网络结构，可以使485总线通信系统的稳定更好。
一、485HUB基本介绍485集线器RS-485/422接口在工业控制中使用相当普遍，采用的都是总线挂接式连接方式，不支持星型连接，一根总线支持的设备有限，且传输距离只有1200米，从而给施工带来了极大的不便，期待着RS-485/422总线分割集中器的诞生。
二、485HUB总线分割H-4485能够轻易的改善系统的总线结构，无需改动设备本身，就能实现不同功能的设备或不同区域的设备分别对待，并构成相互独立的不同网段。
不仅提高了系统的可靠性，而且大大的缩短了系统的维护时间。
星形连接：H-4485通过特殊设计能够向用户提供RS-485/422星型连接方式，从而改变了原有总线单一式结构，为网络结构工程建设带来了极大的便利。
三、485HUB光电隔离在工业控制领域，RS-485总线往往需要把分散的不同设备相互连接起来协同工作，由于环境差异的存在，设备与设备之间往往存在着不同程度的地电位差异，从而影响设备的正常通信。
H－4485为所有端口都提供2500V以上的光电隔离，有效地解决了由距离及地电位差异带来的传输问题。
短路开路保护H-4485在所有端口处都设有短路开路保护，能够保证当其中一个端口设备故障产生时，出现问题的端口将被隔离，以确保其他网段能够正常工作。
1本光纤集线器用于组建星型光纤网络，实现RS－232/485/422在光纤星型网络上透明传输。

This ensures that Brainboxes universal card range is backward compatible with older systems and works with all new PCI systems.More info on'Universal'products:Click HereAutogatingWhen the device is set to half duplex mode, transmitted and received data is sent across the same signal lines.Autogating means the Brainboxes card knows when to 'listen' for data and when to transmit data, with a quick and automatic hardware switch between the 2 modes. This is much faster than software switching and ensures no data loss due to turnaround delay.More Info:Click HereOpto IsolationOptical isolation provides greater protection from electrical current surges to both the card itself and the PC. It improves noise immunity by isolating the PC from the card’s transmit ground.Opto-Isolation: ±1500Volt DC/ 1000Volts ACPCI CompliantAll Brainboxes Universal PCI cards are fully PCI version 3.0 compliant, in accordance with the PCI-Special Interest Group (PCI-SIG).Large FIFOFIFO means First In First Out, a FIFO is memory space on the Brainboxes card. A larger FIFO allows more memory space for buffering data, so calls to the computer processor are less frequent. This significantly increases data throughput and improves CPU availability for other applications.More info:Click Here4Layer PCBPrinted Circuit Board with 4 layers of circuitry complies with the PCI SIG best practice guideline and ensures a more reliable card. 1 layer is for power and 1 for ground which leads to greater EMC shielding for the signals. This ultimately gives greater signal integrity for sensitive timing applications.Surface Mount ComponentsMost components on a Brainboxes card are placed by a surface mount machine. The surface mount machine allows for highly accurate and fast production of Brainboxes cards. Orders can be met quickly, reliably and with outstanding quality.CapacitorsAs required by the PCI-SIG all Brainboxes cards have capacitors connected to all the power pins on the PCI connector, near to the connector. This ensures that the electrical power rails on the Brainboxes card stay at the right voltage, regardless of the power demands placed on them. Data signals keep their integrity.UNIVERSAL DUAL OPTO VELOCITY RS422/485B r a i n b o x e s ' K a i z e n"Brainboxes constantly strives to achieve higher standards for the benefit of customers."‘Kaizen’ is a Japanese term meaning ‘continuous improvement’. Kaizen has been implemented throughout Brainboxes, resulting in significant improvements to our products and our customer service,as illustrated by the development of our own custom ASIC “LYNX” and our new lifetime warranty. As part of this ongoing process, in 2004 we embarked on ‘Lean’ and ‘6 Sigma’ programs which are successfully increasing productivity and efficiency in all areas of the company.More Info:Click HereB r a i n b o x e s ' S e r v i c e“Brainboxes offers free lifetime support for ALL customers.”We aim to provide industry leading support for our customers. Our highly trained and helpful supportengineers sit and work closely with the product designers, developers, and testers to ensure an in-depth knowledge of the products. Support can be found by emailing **********************or calling: +44 (0)151 220 2500 during UK office hours. Support website: /support/index.asp“Brainboxes’ passionately believes in the quality of its manufacturing process and will reflect this byoffering a Lifetime Warranty on ALL of its universal serial card range.”Brainboxes is pleased to be able to extend a new Lifetime Warranty for all universal serial cards products.We have introduced this based on our exceptional manufacturing and design quality and the company ethos of kaizen.R S 422/485 S t a n d a r d sRS422 allows one transmitter and up to 10 receivers with data transmission rates up to 10 Megabits per second, for distances up to 40 feet and up to 100 Kilobits per second, for distances up to 4000 feet (1219 metres).RS485, based on the RS422 standard, allows up to 32 driver/receivers pairs on a party line data bus. This can be configured into half duplex and full duplex mode. Whilst only one of these should be transmitting data at any time, the rest can all simultaneously listen to the data.More Info:Click HereB r a i n b o x e s ' L Y N XWe developed the Brainboxes LYNX (BB16PCI958) to enable us to drive product performance, and supply customer needs for Universal PCI products (3.3v and 5v compatible). By reducing the part count and incorporating several components into one chip (FIFO, UARTs, PCI interface), we have also increased board reliability. The LYNX also features thorough backwards compatibility with legacy systems, tested beyond the databook for compatibility with standard TL16C550, 750 UARTs. The chip is designed so that Brainboxes products will work with all applications designed for TI UARTs. More Info:Click HereRS422/485 Pinout。

可以有效的实现RS485网络的中继、扩展与隔离。
图1 ZLAN9480A外观ZLAN9480A的主口端提供隔离型RS485，从口端扩展出8路隔离型RS485接口。
一般RS485接线时要求手拉手接线方式，需要避免主站为中心的星型连接。
但是某些情况下为了方便，需要采用星型连接，此时采用RS485 HUB可以有效隔离多个RS485之间的连线干扰。
ZLAN9480A有源隔离型RS485集线器产品是专门针对工业现场恶劣环境而设计的，对于那些要求高可靠性和安全性的场合尤其适合。
光电隔离功能可以有效的使RS485主从设备之间彼此隔离开来，避免因主从设备间的地电位差、以上海卓岚信息科技有限公司Tel:(021)64325189 及静电、雷击和浪涌对RS485主从设备造成的损害，同时也有效的避免了主从设备端的地电位差而在设备间产生的地环流对RS485设备造成的损害。
