Introduction
The PCI-1603 offers a versatile range of high speed interfacing options. You can switch its ports between the popular RS-232 or noise-resistant current-loop. The card utilizes 16PCI952 UART with 128-byte FIFO buffer for faster and more reliable communication, especially under multi-tasking environment such as Windows operating systems. The PCI-1603 provides two isolated RS-232 or current-loop serial ports. You can configure each port individually to RS-232 or current-loop using on-board jumpers. The card utilizes 16PCI952 UART that buffers data into packets before putting it on the bus. This drastically reduces CPU load and avoids data loss when the system is busy and cannot process the interrupt quickly. These FIFO buffers make the PCI-1603 especially suitable for high speed serial I/O under Windows. On-board optical isolators protect your PC and equipment against damage from ground loops, increasing system reliability in harsh environment.
