Each port utilizes a 16C550 UART with an on-chip 16-byte FIFO buffer for reliable, high-speed serial I/O. The UART buffer divides data into 16-byte packets before sending them onto the bus. This drastically reduces CPU load and avoids data loss due to failure to respond to the interrupt 8 8 request in time. The UART is especially useful for high speed serial I/O under Windows. ADAM-3000 The PCL-745B/745S card differs from the PCL-743B/743S card in that the former uses on-board optical isolators to protect your PC and equipment against damages from ground loops, increasing system reliability in harsh environments. To further increase reliability, PCL-743S and PCL-745S offers surge protection, protecting your system from abrupt high 9 voltage surges (up to 2500 V ) such as those caused by lightning.
