PCI To RS422 RS485 Card PCI to 2 Port RS485 or RS422 Serial Converter Adapter Features: PCI to RS422andRS485 converter is a universal converter from PCI to RS485andRS422 without extra power supply, compatible with PCI RS422, RS485 standard. It converts PCI signals to balanced differential RS422 or RS485 signals. Each line is protected by surge protection and various surge voltages. Tiny capacitance distances ensure a high-speed transmission interface for RS422 or RS485. RS422 or RS485 is connected via RJ45 and DB9 connectors. The converter has a built-in zero-delay auto transceiver, and the I or O circuitry automatically controls the direction of data flow without the need for any handshaking signals (e.g., RTS, DTR, etc.) and jumper sets to achieve full-duplex and half-duplex mode conversion, plug-and-play. Ensure all existing communication software and hardware interfaces of the product. Each serial signal for additional TVS transient diode, can be the following 400W surge signal crosstalk, communication stability. PIN-in optoelectronic isolation and DC-DC voltage converter, can effectively isolate the external pressure to avoid the impact of equipment.
