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.

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.

Refer to the user manual for details on configuring all serial settings as required for RS-232 communication.

GPIB

The power supply can be configured with a GPIB address from 0 – 31. To communicate via GPIB, connect a GPIB cable to the GPIB interface on the rear panel, as illustrated below.

Note: Pin 1 is used as the B pin (+) (non-inverting).

SC (reference) pin is not used.

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.

Pin 5 is used as the A pin (-) (inverting).

USBTMC

The device is SR1, RL1, and DT1 enabled. It can receive the following request: REN_CONTROL, GO_TO_LOCAL, LOCAL_LOCKOUT. When it receives MsgID = TRIGGER USBTMC command, it will transmit TRIGGER command to the function layer.

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. Setting parameter can determine which bit of standard event register is 1 and the byte will enable ESB of status byte register as 1. Command syntax: *ESE <NR1> Parameter: 0~255 The value when power on: Refer to *PSC command Example: *ESE 128 Query syntax: *ESE? Returned parameter: <NR1> The bit definition of the standard event enabled register:

PON Power-on CME Command error EXE Execution error DDE Device-dependent error QYE Query error OPC Operation complete

*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: <NR1>

*IDN?

This command can read information about power supply. The returns parameter contains 4 segments divided by comma. Query syntax: *IDN? Parameter: None Returned parameter: <AARD> segment description B&K Precision Manufacturer 9115 Product model XXXXXX Product serial number VX．XX –VX．XX Software version Example: B&K Precision, 9115, 00000000000004, V1.01-V1.00

*OPC

When all commands before this command are executed, bit OPC in standard event register will be set to 1. Command syntax: *OPC Parameter: None Query syntax: *OPC? Returned parameter: <NR1>

*RST

This command resets the power supply to default settings. Command syntax: *RST Parameter: None

*SRE

This command can set the parameter of state byte enable register. Setting parameter can determine which byte value of state byte register is 1 and the byte will set RQS of state byte register to 1. Bit definition of state byte enable register is the same as the state byte register. Command syntax: *SRE <NR1> Parameter: 0~255 Query syntax: *SRE? Returned parameter: <NR1>

*STB?

This command can read the data from status byte register.
