Description

8-port RS-485 hub (HUB) Manual

COOLFIRE 8 Ports RS485 hub uses intelligent multi-core processors internally, designed for solving complex electromagnetic environment, RS-485 large-scale system requirements and design RS-485 bus split hub (HUB). In order to ensure the safety and reliability of data communication , RS-485 Interface end smart isolation techniques to prevent the introduction of lightning surge converters and equipment , built-in isolators and 1500W surge protection circuit , provides security isolation voltage 500V , can effectively suppress Lighting and ESD, lightning and common ground to prevent interference . powered using an external 12-24V DC power supply , versatility, safety and reliability , ideal for indoor and outdoor engineering applications .
Hubs internal use industrial grade super anti- high-speed chip ( currently on the market only high-performance implementations ah ) machine to achieve intelligent identification circuit can automatically sense the direction of data flow , and automatically switch to control circuit , easy to solve RS-485 transceiver conversion latency problem . RS-485 interface, the transmission distance is greater than 5000 meters , is a high performance, excellent price data interface conversion product.

The device uses advanced SMT automatic welding technology, SCM software, intelligent analysis and processing technology , product quality, far more than other handmade products.

back of the fixture can be used with DIN rail mounting, DIN rail inexpensive , casual interception , suitable for industrial control cabinets. metal box . PZ-30 boxes and other installations , ease of maintenance and replacement ; also used four mounting side hole mounting .

The RS-485Hub provides bus connections to the star of the conversion, the user can easily improve the RS-485 bus architecture , split segments, improve communication reliability when lightning strikes or equipment failure occurs, the problem of the network will be isolated in order to ensure other networks to work properly. this greatly improves the performance of existing RS-485 network reliability, effectively shortening the network maintenance time. rational use of RS-485 hubs can help you design a unique highly reliable RS- 485 system .
