BG Series Goniometric Cradles —Connection to Newport Controllers Warnings on Controllers Controllers are intended for use by qualified personnel who recognize shock hazards and are familiar with safety precautions required to avoid possible injury. Read the controller user’s manual carefully before operating the instrument and pay attention to all written warnings and cautions. -
Page 20: Connection
BG Series Goniometric Cradles Connection There is a label on every stage indicating its part and serial numbers. WARNING Always turn the controller's power OFF before connecting to a stage. NOTE These stages are ESP compatible. Enhanced System Performance is Newport's exclusive technology that enables Newport ESP motion controllers to recognize the connected Newport ESP stage and upload the stage parameters. -
Page 21: Mcab-3 Cable
BG Series Goniometric Cradles REMARK The cross section of the MSCAB-10 cable is different from the one of the MSCABLE-3 cable to allow a longer length. The MSCAB-10 cable has the same mechanical properties as the MCAB-10 cable. These cables are specially shielded and terminated with Newport’s standard SUB-D15 and SUB-D25 connectors. -
