Delta Tau: PMAC Mini PCI

The PMAC Mini PCI is a compact, 2-axis version of the PMAC(1) family (unless accessories are added to expand the number of axes). It can be used in a PC’s PCI slot as a half-sized board (230 mm, 9” long) or it can be used standalone using serial communications for setup and/or application control. Programs for the PMAC Mini PCI (both motion and PLC programs) are 100% compatible with other versions of Non-Turbo PMAC. 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.
