High speed engraving and milling machine control system is used in PCI interface chip CH365, the chip is a universal PCI bus interface chip, support the I/O port mapping, mapping, expansion ROM and interrupted operation.
CH365 to 32-bit high speed engraving and milling machine of PCI bus is converted into a simple similar to the ISA bus 8-bit parallel interface, computer interface card based on PCI bus is used in making cost, and the original upgrade to the PCI bus based on ISA bus interface card, its main characteristic is to realize from the device based on the 32 bit PCI bus, converted to active parallel interface.
High speed engraving and milling machine control system of the PCI interface circuit as shown in the figure below.
