GO-400 Multifunction Data Acquisition Card
Overview
The GO-400 is a multifunction PC acquisition card providing analog and digital inputs/outputs, high precision operation for quadrature incremental encoders, timer/counter for real-time operation and counting external events. The GO-400 offers a compact solution for position and speed measurements on an IBM/AT-compatible PC. The evaluation of the incremental encoder signals and communication with PC are performed completely by a FPGA chip. The acquisition card requires a 16-bit PC-slot (ISA or PCI bus) and uses the supply voltage +5V from the PC bus. The shipment includes interconnect module, 100-pin SCSI-type cable, extensive manual, software for function testing, driver routines in C and C++ source code.
