RS485/422 HUB

Insert card configuration Star structure Short circuit and plough protection Bus division and focus RS-485/422 interface wildly used in industry control, It use BUS connection, no support star connect, transfer distance 1200M,one bus can only support 256 nodes,the BUS connection have 3KV isolation, It bring many difficult to engineer. RS-485/422 Bus division and focus organ emerge as the times requireInsert card configurationOCTOPUS3000 is a 1-8port insert card format optic electricity RS-485/42 Bus division and focus organ, users can configure insert card at will, it support RS-232/RS-485 convert and RS-232/RS-422 convert, can also support repeater. if have mangle and extend capacity, only need exchange or add insert card, be good for advance the maintenance efficiency.Star structureOCTOPUS3000 thread especially design can face users supply RS-485/422 Star connect, in the industry control domain, RS-485 bus usually connect all kinds of services in different place to work together, Because different place have different environment, It exist different ground voltage between the different equipment, it influence equipment communication in gear. OCTOPUS3000 each interface supply up to 3000V optic electrical isolation, availably solve the communication problem because of the distance and different ground voltage. The format change the bus singleness structure to network structure let the engineering more expediency.Short circuit and plough protectionOCTOPUS3000 setup short circuit and carve out a way protection at all ports, the design can assure other network segment work in gear if one of the ports equipment bring failure, the port that appeared failure will be isolation.Bus division and focusOCTOPUS3000 can easily change system's bus structure, it treat the separate equipment in different function or different area, and form one another independence different network segment, have no use for changing the equipment itself. it not only increase system's security, but also greatly abridge the system's maintenance time. Features1. Supply 4-8 port RS-485/422 signal focus function2. Each port support 256 point loopback3. All interface can supply more than 3kv optic electrical isolation4. All ports setup short circuit and plough protection5. Support RS-232/RS-485 convert and RS-232/RS-422 converter, can also support relay.6. Adopt beforehand aggravation technology design, even if the rate is at 9600pbs, traffic distance also can reach up t o 3000M.7. Use ADDC, auto text and control data transfer direction8.
