The Turbo PMAC2 PCI is a member of the Turbo PMAC family of boards optimized for interface to sinewave or direct-PWM servo drives and to pulse-and-direction stepper drives. It is capable of 32 axes of control. It can have up to eight channels of on-board axis interface circuitry. It can also support up to 32 channels of off-board axis interface circuitry through its expansion port, connected to ACC-24P or ACC-24P2 ISA-format boards (ACC-24 boards in PCI format are not yet available).
The Turbo PMAC2 PCI is a full-sized PCI-bus expansion card, with a small piggyback board containing the CPU board. This piggyback board occupies part of the next slot, but ½-sized boards are permitted in this next slot. While the Turbo PMAC2-PCI is capable of PCI bus communications, it can also be operated standalone and can be communicated with over a RS232 or RS422 serial port.
