  • Page 4: Remote Operation

    1 Remote Operation 1.1 Interface Connection RS-232 For RS-232 connectivity, refer to the diagram below for pin out information. The RS-232 is labeled in the rear panel and it is a female DB-9 interface. Description Transmit Data Receive Data A straight pin-to-pin DB9 female to DB9 male serial cable is required for using the RS-232 interface.

  • Page 5: Remote Commands

    2 Remote Commands 2.1 Parameter Definitions The 9800 Series power supplies support communication protocols, which include standard SCPI commands and a few proprietary commands that follow the SCPI convention. The SCPI interface enables users to operate the power supply through a computer or a terminal equipped with RS-232, or USB interface.

  • Page 8: Status Subsystem

    Parameter: 0~9 2.3 STATUS Subsystem You can get the current status of the power supply by reading the operation status registers. The power supply records the different status of the instrument through the four status register group. The four status register groups are: status byte register, standard event register, query status register and operation status register.
