Introduction  

Octopus3000 is a type of RS-485/422 bus division concentrator of high performance. Octopus3000 adopts the unique equipotential differential isolation and bus division concentration technology to effectively such problems as ground potential difference, impedance matching and lightning strike frequently seen in engineering wiring process. Users can easily optimize the RS-485/RS-422 bus structure, divide the network section and improve the communication reliability.

The fault network section shall be isolated in case of lightning strike or equipment faults to ensure the high communication reliability of other network sections. Such performance of Octopus3000 can significantly improve t he reliability of existing RS-485/RS-422 network, and effectively shorten the network maintenance time. Reasonable utilization of Octopus3000 can enable you to design unique RS-485/RS-422 system.

I nsert Card Structure

Octopus3000 is a type of 8-port insert card photoelectric isolation RS-485/422 bus division concentrator, which is available for random configuration of insert card by users, and can also realize the dual conversion between RS-232 and RS-485/RS-422 as well as he RS-485/422 relay function. It is only need to replace or add insert card in case of damage and capacity expansion to effectively improve the maintenance efficiency.

Photoelectric Isolation of Industrial Level

Normally, RS-485 bus is required to link up different equipments for coordinated operation in industrial control domain. Due to environmental differences, ground potential differences among equipments may affect the normal communication of equipments. Octopus3000 aims to provide photoelectric isolation above 3KV for all ports for the purpose of solving the transmission problems incurred by distance and differences in ground potential (Octopus3000 can adapt to the RS-485/422 transmission mode, which is provided with 5-digit industrial terminal).

Protection for Short and Open Circuits

Octopus3 000 is provided with protection for short and open circuits at all ports. This type of design can ensure the isolation of problem port if one of the port equipments is in failure so as to ensure the normal operation of other network sections.

Star-shape Connection

Owing to the unique design, Octopus3000 can provide users with RS-485/422 star-shape connection mode. This mode can change the single structure of original bus into network structure to facilitate the engineering construction significantly.

Bus Division Concentration

Octopus3000 can easily optimize the system bus structure for respective handling of equipments of different functions or of different regions for the purpose constituting different independent network sections without changing equipment itself. This can not only improve the system stability but can also significantly shorten the system maintenance time.
