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.

Insert 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.

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.
