ABOUT PMAC PCI
The PMAC PCI is a member of the PMAC family of boards optimized for interface to traditional servo drives that use single analog inputs representing velocity or torque commands. It is capable of eight axes of control. It can have four to eight channels of on-board axis interface circuitry.
The PMAC-PCI is a full-sized PCI-bus expansion card, with a small piggyback board containing the CPU board. While the PMAC-PCI is capable of PCI bus communications, with or without the optional dual-ported RAM, it does not need to be inserted into a PCI expansion slot. The PC can communicate to PMAC through the PCI slot or through a RS-232 or RS-422 serial port if standalone operation (i.e. without a PC) is desired.
