PCI TO RS422/RS485 Convertor is a universal converter of PCI to RS485/RS422, which is without addition power supply, compatible with PCI, RS422, RS485 standards. It can convert PCI signals to a balanced differential RS422 or RS485 signals. Each line has surge protection, and various surge voltage protections. The tiny capacitance distance guarantees RS422 / RS485 interface of high-speed transmission. RS422, RS485 connect by RJ45 and DB9 interface. Converter with zero delay automatic transceiver inside, unique I/O circuit automatically control data flow direction, without any handshake signals (such as RTS, DTR,etc.) and jumpers set realize full-duplex, half-duplex mode conversion, plug and play. Ensure the product fix for all existing communication software and hardware interface.
Function
PCI TO RS422/RS485 convertor supports four communication modes:
1, Point-to-point / 4-line full-duplex
2, Point-to-multi point / 4-line full-duplex
3, Point-to-point / 2-line half-duplex
4, Point-to-multi point / 2-line half-duplex
When the convertor is working at full-duplex or half-duplex, needs to add a matched resistance to avoid reflects and disturbance of signal. ( 120Ω，1/4W)
