What I recommend to you today is an industrial-grade PCI-E to 8-port RS422/485 multi-serial expansion card. This multi-serial expansion card will allow users to add 8 standard RS422/485 serial ports to a desktop computer or server, using a bidirectional interface. Protection, providing 500W lightning surge protection power per line and 20KV ESD full signal electrostatic protection, ensuring high-speed and stable transmission of the RS422/485 interface. A short iron piece is delivered and can be used in any large or small (2U) chassis. Applicable to all RS422/485 interface devices, including POS machines, access control, ATMs, embedded industrial automation equipment, financial payment ATM systems, transportation systems, factory automation and process control, medical systems, remote access servers, etc.
8 standard RS422/485 serial ports
Equipped with 8 standard RS422/485 serial ports, it automatically realizes RS422/485 communication without jumper settings. Users can communicate simultaneously by connecting 8 serial devices to achieve simultaneous communication with multiple serial device ports.
RS422 signal: T/R+, T/R-, RXT+, RXT-, GND;
RS485 signal: DATA+(B),DATA-(A),GND;
RS422 working mode: point-to-many full-duplex two-way communication;
RS485 working mode: point-to-many half-duplex communication.
Desktop industrial grade PCI-E to 8-port RS422/485 multi-serial expansion card PCIE X1 bus interface design, suitable for PCI Express X4, X8, X16 slots, not for PCI slots. A short iron piece is delivered and can be used in any large or small (2U) chassis. It adopts an interface bidirectional protection design to provide 500W lightning surge protection per line and 20KV (ESD) full signal electrostatic protection capability, which can improve the high-speed stability of the equipment.
