Background

The normal configuration settings (F-01~F-61, F-88, F-89) are used to configure or view system settings. Use the following operation steps when configuring the interface settings used in the Remote Control chapter. Ensure the load is not connected. Ensure the output is off.

Note

Configuration settings F-90~F-95 cannot be edited in the Normal Function Settings. See the user manual for details. The F-89 settings can only be viewed, not set.

Steps.

Press the Function key. The function key will light up.

Before using the USB remote control, you will need to install the USB device driver(inf file) that is included on the CD accompanying accessories.

Panel operation

Connect the USB cable to the rear panel USB B port.

Press the Function key to enter the Normal configuration settings.

Set the following USB settings:

F-22 = 2

Set the rear panel USB port to USB-CDC.

F-22 = 3

Set the rear panel USB port to USB-CDC (Full speed only)

Configure GP-IB

Ensure the PSW is off before proceeding.

Connect the USB cable from the rear panel USB B port on the PSW to the USB A port on the GP-IB to USB adapter.

2. REMOTE CONTROL

This chapter describes basic configuration of IEEE488.2 based remote control.

2.1 Interface Configuration

2.1.1 USB Remote Interface

2.1.2 Configure GP-IB Interface

To use GP-IB, the optional GP-IB to USB (GUG-001) adapter must be used. The GP-IB to USB adapter must be connected before the PSW is turned on. Only one GP-IB address can be used at a time.

2.1.3 Configure Ethernet Connection

The Ethernet interface can be configured for a number of different applications. Ethernet can be configured for basic remote control or monitoring using a web server or it can be configured as a socket server. The PSW series supports both DHCP connections so the instrument can be automatically connected to an existing network or alternatively, network settings can be manually configured.

Page 14

Configuration

This configuration example will configure the PSW as a web server and use DHCP to automatically assign an IP address to the PSW.

1.Connect an Ethernet cable from the network to the rear panel Ethernet port.

LAN

2. Press the Function key to enter the Normal configuration settings.

Set the following LAN settings:

F-36 = 1

Enable LAN

F-37 = 1

Turn DHCP to enable

F-59 = 1

Turn the web server on

Note

It may be necessary to cycle the power or refresh the web browser to connect to a network.

Configuration

This configuration example will configure the PSW for web sockets control. The following configuration settings will manually assign the PSW an IP address and enable web sockets. By default, the socket port number is 2268 and cannot be configured.

1. Connect an Ethernet cable from the network to the rear panel Ethernet port.

The socket function is only available for firmware version V1.12 or above. See the user manual to check your firmware version number.

Functionality check

Install a driver(TEXIO_CDC.inf) from Manual CD. The USB device driver of psw is more downloadable than our homepage . When USB connects psw to a computer for the first time, installation of the USB device driver is required.

Please perform the installation from the Device Manager if a computer can’t recognize psw. Control Panel – All Control Panel Items – Device Manager – Other Device – PSW (Right click)

– Update driver Software

Please prepare the Terminal application(Such as PuTTY or RealTerm). Serial communication settings are as follows.

Baud rate

: 9600bps

Data length

: 8bit

Parity bit

: None

Stop bits

: 1bit

Flow control

Run this query command via the terminal after the instrument has been configured for USB remote control. *idn? This should return the Manufacturer, Model number, Serial number, and Firmware version in the following format.

Command Structure

SCPI commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node. Each keyword in a SCPI command represents each node in the command tree. Each keyword (node) of a SCPI command is separated by a colon (:).

For example, the diagram below shows an SCPI sub-structure and a command example.

MEASure

SCALar

POWer

VOLTage

CURRent

MEASure:SCALar:CURRent:DC?

Command types

There are a number of different instrument commands and queries. A command sends instructions or data to the unit and a query receives data or status information from the unit.

Command types

Simple

A single command with/without a parameter

Example

*IDN?

Query

A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned.

Example

meas:curr:dc?

Compound

Two or more commands on the same command line. Compound commands are separated with either a semi-colon (;) or a semi-colon and a colon (;:). A semi-colon is used to join two related commands, with the caveat that the last command must begin at the last node of the first command. A semi-colon and colon are used to combine two commands from different nodes.

Example

meas:volt:dc?;:meas:curr:dc?

3. Command Syntax

Page 23

Command Forms

Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case. The commands can be written in capitals or lower-case, just so long as the short or long forms are complete. An incomplete command will not be recognized. Below are examples of correctly written commands.

Long form

STATus:OPERation:NTRansition? STATUS:OPERATION:NTRANSITION? status:operation:ntransition?

Short form

STAT:OPER:NTR? stat:oper:ntr?

Square Brackets

Commands that contain square brackets indicate that the contents are optional. The function of the command is the same with or without the square bracketed items, as shown below. Both "DISPlay:MENU[:NAME]?" and "DISPlay:MENU?" are both valid forms.

Overview

The status registers are used to determine the status of the power supply. The status registers maintain the status of the protection conditions, operation conditions and instrument errors.

The PSW Series have a number of register groups:

・Questionable Status Register Group ･Operation Status Register Group ･Standard Event Status Register Group ･Status register group

5. Status Register Overview

To program the PSW power supply effectively, the Status registers need to be understood. This chapter explains in detail how the Status registers are used and how to configure them.

Page 65

Condition Register

The Questionable Status Condition Register indicates the status of the power supply. If a bit is set in the Condition register, it indicates that the event is true. Reading the condition register does not change the state of the condition register.

PTR/NTR Filters

The PTR/NTR (Positive/Negative transition) register determines the type of transition conditions that will set the corresponding bit in the Event Registers. Use the Positive transition filter to view events that change from false to positive, and use the negative transition filter to view events that change from positive to negative.

Positive Transition Negative Transition

0→1 1→0

Event Register

The PTR/NTR Register will dictate the type of transition conditions will set the corresponding bits in the Event Register. If the Event Register is read, it will be cleared to 0.

Enable Register

The Enable register determines which Events in the Event Register will be used to set the QUES bit in the Status Byte Register.
