DC SIGNAL SOURCE

Introduction

This manual details the methods to operate the SS7012 DC Signal Source using communication functions, as well as all the commands used by the SS7012. When the communication function is used, the SS7012 can be manually oper-ated using communication terminal software. Furthermore, application software to automatically control the SS7012 can be run.

Safety Information

• The following symbols in this manual indicate the relative importance of cautions and warnings.
• Indicates that incorrect operation presents a possibility of injury to the user or damage to the instrument.
  Indicates advisory items related to performance or correct operation of the instrument.

SS7012 Remote Interface Overview

Operating principle

• Communication between a personal computer and the SS7012 is virtual RS-232 serial communication. While the USB interface is installed as the transmission route, actual communication uses RS-232.
• It is necessary to issue RS-232 commands via the virtual COM port.
• When RS-232 commands are issued to the virtual COM port, commands are sent to the SS7012 in the following order. (For the receipt of data, the order is reversed.)

Connect a USB cable

• Before connecting the USB cable, install the USB driver on the personal computer. The USB driver is located on the CD that accompanied the SS9000 Communication Package.
• For installation instructions, please refer to the instruction manual of the SS9000 Communication Package.
• After installing the USB driver, connect the personal computer and SS7012 as shown in Figure 2. The virtual RS-232 COM port will be automatically assigned to the USB port.

Setting Remote Interface Parameters

• In order to send communications, the serial interface parameters of the SS7012 and personal computer must match.
• Table 1 shows the settings required for communication. These parameters are fixed. If any other settings are used, communication is not possible.

Table 1: Remote Interface Parameters (All fixed values)

Enabling key operation

• While the SS7012 is communicating, key operation of the SS7012 cannot be used. (On the LCD of the SS7012, is on.)
• To enable key operation of the SS7012, push the LOCAL key of the SS7012. goes out.

Commands Summary

• Overview of Command Type and Format
  All commands can be entered in upper and lowercase.

• Command Format and Query Format
  The commands control instrument functions.
  The following example shows a command and its associated query:

• Query Command
  The query command ends with a question mark “?”.

• Terminator (delimiter)
  A terminator is a character, which identifies the end of a command string. A valid terminator consists of two-byte data:

  (Carriage Return, ASC(&H0D)) (Line Feed, ASC(&H0A))

Response Messages

• Return Result

  • After the instrument executes a query command the return of the result will be in the following format:

  • The format of measurement data will be shown as following:

  • The format of monitor data will be shown as following:

  • The format of setting command will be shown as following:
    (Response 1) OK

  • (When the setting command was pro- cessed normally)
    (Response 2) CMD ERR (When there is an error in the transmission command)

• Data Types

  • Returned message is the ASCII string from the instrument responding to a query.
  • A query is a command followed by a question mark.
  • The following table 2 is explanation for data types.
