            485 shared device

            Product Classification:Peripheral auxiliary equipment

            Home price:¥0.00


            Functional overview:

            485 the shared device can solve the problem of operation conflict and authority among multiple control devices.

            product details

            AT485W4-1 four way sharing device supports multiple RS485 control equipment such as Kang, UOB, Hanbang etc. DVR DVR, PELCO protocol, 485 domestic matrix ball machine direct control keyboard can control a plurality of ball machine hanging on the same bus control equipment, operation and solve the conflicts between control equipment and control permissions. Complex problems of centralized control ball machine suitable for monitoring center multiple control equipment. The device can be connected, is on a set of AT485W4-1 output to the next AT485W4-1 input, so as to support more control equipment. AT485W4-1 supports four way 485 input, 485 output, that is, 4 into 1 out of the.
            Functional characteristics
            Four RS485 input ports, shared control of a RS485 output port. Between the various ports for the full photoelectric isolation, independent drive, do not affect each other.
            Each input port is corresponding to the corresponding indicator light, you can quickly determine the field bus which is a problem.
            Compatible devices with different communication protocols, pure hardware on the RS485 485 bus signal separation
            Fundamentally solve the problem can not be multiple devices (hard disk recorder) control multiple devices (ball machine).
            Suitable for multiple RS485 devices, the need to control the use of the same RS485 device environment.
            Can be cascaded to extend the capacity of the input device.
            485 each port of the shared device is isolated and mutually independent, which ensures the stability of the whole system.
            485 the sharing device adopts almost zero time delay design, data can be two-way transmission, automatic discrimination flow.
            technical parameter
            Interface characteristics: serial RS-232 / 485 protocol
            Electrical interface: serial port interface terminal
            Transmission media: five super shielded twisted pair line or 485 special line
            Working mode: asynchronous operation, point to point or multi-point, 2 line half duplex
            Isolation: isolation voltage 3000V
            Transmission distance: RS-485 end 1200 meters, RS-232 side recommended not more than 5 meters
            Size: 120L * 80W * 25.5H mm (with terminal size: 140L * 105W * 25.5H mm)
            The use of the environment: temperature: -20 degrees centigrade - 60, humidity: 5% - 95%
            Transfer rate: 115200bps - 300BPS
            Multiple control terminals (such as the control keyboard, matrix,
            Hard disk recorder, etc.) at the same time control one or more of the total
            Line ball machine and PTZ decoder etc.
