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. 5 4 9 PIN 1 2 3 4 5 6 7 8 9 3 8 2 7 1 6 Description Transmit Data Receive Data GND - A straight pin-to-pin DB9 female to DB9 male serial cable is required for using the RS-232 interface. Do not use a null modem or crossover DB9 serial cable.
PAGE 5
RS-485 For multi-unit configuration and control, the male DB-9 interface labeled RS-485 in the rear panel is used. The below illustrates the connection pins and description. Note: Pin 1 is used as the B pin (+) (non-inverting). Pin 5 is used as the A pin (-) (inverting). SC (reference) pin is not used. 5 4 9 PIN 1 2 3 4 5 6 7 8 9 USBTMC 3 8 2 7 1 6 Description B (+) A (-) - The device is SR1, RL1, and DT1 enabled. It can receive the following request: REN_CONTROL, GO_TO_LOCAL, LOCAL_LOCKOUT.

2 Remote Commands 2.1 IEEE488.2 Common Commands Here’s a list and description of all common SCPI commands supported by the instrument. *CLS This command clears the following registers. Standard event register Query event register Operation event register Status byte register Error code Command syntax: *CLS Parameter: None *ESE This command can set the parameter of standard event enable register.
PAGE 7
*ESR? This command can read the value of standard event status register. After executing this command, standard event status register is reset. Bit definition of standard event status register is the same as the standard event status enable register. Query syntax: *ESR? Parameter: None Returned parameter: *IDN? This command can read information about power supply. The returns parameter contains 4 segments divided by comma.
PAGE 8
Query syntax: *STB? Parameter: None Returned parameter: *TRG When power supply trigger source is a command from via BUS, this command will give a trigger signal. And its function is the same as “TRIGger” command. Query syntax: *TRG Parameter: None Returned parameter: None *SAV This command can save the current setups of power supply to specified memory.

All the parallel operations are completed. Query error. Output buffer data lost. Instrument memory data loss or self test error Execute error. Command parameter over flow or the operation condition is not consistent Command error. There is syntax or semantic error in the command received.

STATus:QUEStionable:CONDition? This command is used to read the value of query condition register. When a bit of QUES condition changes, the bit value corresponding in QUEST event register is 1. Query syntax：STATus:QUEStionable: CONDition? Parameter: None Returned parameter: STATus:QUEStionable:ENABle This command can set the parameter of quest event enable register. Setting parameter can determine which bit value of quest event register is 1 and the bit will enable QUES.

Command syntax: SYSTem:RWLock Parameter: None SYSTem:POSetup This command configures the power on state of the instrument. Command syntax: SYSTem:POSetup RST|SAV0 Parameter: RST|SAV0 Returned parameter: None Query syntax: SYSTem:POSetup? SYSTem:POSetup? Command syntax: SYSTem:POSetup? Parameter: None Returned parameter: RST|SAV0 SYSTem:CLEar This command is used to clear the error codes and information.

This command is used to set the slave machine’s address when communicating through RS485 interface. Command syntax: ADDRess Parameters: 0-31 2.4 TRIGGER Subsystem TRIGger[:IMMediate] This command is used to create a trigger signal. It will give a trigger signal in BUS trigger source mode. The function is the same as command *TRG. Command syntax: TRIGger[:IMMediate] Parameter: None Related commands: *TRG TRIGger:SOURce This command is used to select the trigger source.

[SOURce:]FALL[:LEVel] This command is used to set the voltage falling time of the power supply. Command syntax: [SOURce:] FALL [:LEVel] Unit: s parameter: 0~65.535 Query syntax: [SOURce:] FALL [:LEVel]? Return parameter: 0~65.535 [SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude] This command is used to set the output current value.
