PCIe to Rs485/422 Serial Port Card Com Adapter

PCIe to Rs485/422 Serial Port Card Com Adapter Description

It is compatible with PCIe GEN2.0 (2.5GT/s) and has 2 ports, each with many enhanced features.
Surge protection, optoelectronic isolation protection, DC-DC protection enable it to work normally in more demanding environments, achieve RS485 half duplex and RS422 full duplex control, and achieve bidirectional data transmission with a transmission distance of up to 1.2 kilometers. A single port can support up to 32 devices
Simultaneous communication, therefore it is applied in many and situations.
The SE-SLV354A-2S PCI-E RS422/RS485 multi port I/O card adopts the high-performance EXAR-17V354 chipset.Compliant with PCI Express version 2.0
