The PCI488 is an IEEE 488.2-compliant GPIB controller board for PCI bus computers, enabling direct communication and control of up to 14 IEEE 488 instruments. Built for engineers and system integrators, it delivers data transfer rates exceeding 1 MB/s with an onboard DMA controller to minimize processor load. The board implements full Talker/Listener/Controller functionality, supporting both HP-style and National Instruments command sets with complete IEEE 488.2 feature support including serial poll, device clear, group execute trigger, and parallel poll operations.
