cPCI 6U Series

Hartmann Electronic’s CompactPCI 6U Professional Series features a sleek board design based on High Speed Design concept with exceptionally low-level reflection. The featured reflection levels are achieved by means of uniform signal surge impedance. The design features an energy buffering feature which works across the entire frequency range. This guarantees improved reliability thanks to more stable supply-voltages directly at each slot in conjunction with fluctuating loads. Continuous electrically conductive chassis GND surface located in the area where the backplane is mounted on the card rack. An M3 screw connection is available to connect chassis ground. By installing a connecting bracket or busbar, chassis GND can be connected to ground in a low-resistance star arrangement. Separate 6-pin JTAG boundary scan connector is standard. Faster, simpler system initialization and testing via the JTAG bus when mounted in the chassis is achieved by direct access via an additional connector on the backplane. Main operating voltages are supplied via busbar/screws.
