PCL-745B dual port high speed RS-232/485 interface card Main Features 2 independent RS-422/RS-485 serial interface with 3000 VDC isolation protection 3000 VDC isolation protection 16C550 UART with 16-byte FIFO transfer rate up to 921.6 Kbps I / O address and interrupt the optional data sheet (PDF) technical data download Products PCL-745 series cards can provide you with 2 RS-422/485 serial port. Each port to use a the 16C 550UART chip with 16-byte FIFO buffer, to be able to provide you with high-speed, reliable serial I / O UART can send data to the bus before its buffer treated as a 16-byte data packet, which can significantly reduce the CPU load, to avoid the loss of data caused by the absence of a timely response data request fault. FIFO buffer is very suitable for high-speed serial I / O under Windows. PCL-745B card PCL-743B card difference is that the former optical isolator to protect your PC and equipment against the destruction of the interfering signals impact, greatly enhancing system reliability in harsh environments.
