The product information is as follows:
Name:Control Card ST335 PCIe X1 17V352 2S Industrial RS232/RS485 Multifunctional Convenient Communication Control Card
Load capacity:supports point-to-multipoint transmission, each conversion port supports up to 32 RS485/RS422 devices
SE-SLV352A-2S PCI-E RS422/RS485 multi-port I/O card uses the high-performance EXAR-17V352 chip
It is compatible with PCIe GEN2.0 (2.5GT/S), and it has 2 ports, each port has many enhanced features. For example: 256-byte TX and RX first-in-first-out, programmable baud rate generator, automatic hardware or software flow control, and it comes with Surge protection, photoelectric isolation protection, DC-DC protection enable it to work normally in more harsh environments, and can achieve RS485 half-duplex and RS422 full-duplex control.
It can also realize two-way data transmission with a transmission distance of up to 1.2 kilometers, and a single port can support up to 32 devices.
Simultaneous communication, so it is used in many various occasions
Way of working:
RS422:asynchronous work, point-to-point, point-to-multipoint full-duplex communication mode
RS485:point-to-point, point-to-multipoint half-duplex communication mode
