The Pulse Instruments PI-31001 PI-Bus Interface Card is a replacement for
the 4001 Control Mainframe.
It is designed to drive the 4000 Series' PI-Bus from the CompactPCI
mainframe. The included PI-Controller control software controls 4000
Series commands to be sent over the PI-Bus via the PI-31001.
The PI-Bus Interface Card maintains the Optical isolation between the control unit and the instrument mainframe as in the PI-4001. This prevents the
transfer of digital noise from the CompactPCI chassis to the instrument mainframes. The PI-31001 can control up to seven PI-4002 Instrument Mainframes over a
maximum cable length of 20 feet. The PI-Bus connector is for the
shielded ribbon cable as used on the 40090-A-X interconnect cable.
