Introduction
This chapter provides basic information on remote control, for example on the RS 232-C
interface, IEC/IEEE bus, interface and device messages, command processing, status
reporting system, etc. The instrument is equipped with RS-232-C interface and optionally
with an IEC/IEEE-bus interface according to standard IEC 625.1/IEEE 488.1. The
connectors are located at the rear of the instrument and permit to connect a controller for
remote control. The instrument supports the SCPI version 1999.0 (Standard Commands
for Programmable Instruments). The SCPI standard is based on standard IEEE 488.2 and
aims at the standardization of device-specific commands, error handling and the status
registers.
For this section it is assumed that the user has basic knowledge of IEC/IEEE-bus
programming and operation of the controller. A description of the interface commands
will be found in the relevant manuals.
The requirements of the SCPI standard regarding command syntax, error handling and
configuration of the status registers are explained in detail in the respective sections.
Tables provide a fast overview of the bit assignment of the status registers. The tables are
complemented by a comprehensive description of the status registers. A description of
commands is given in this manual as well as programming examples for the main
functions. The examples for IEC bus programming are all written using VISA C API.
Getting Started
The short operating sequence in this chapter will help you quickly get started with the
instrument’s basic functions and operation.
Assumptions
•
Instrument will be connected to the port COM1 of the controlling computer.
Default factory settings: Baud Rate = 115200, Data Bits = 8, Stop Bits = 1, Parity
= None, Handshake = RTS/CTS.
•
HyperTerminal program will be used to communicate with the instrument.
Procedure
1. Connect the instrument and the controlling computer.
2. Run HyperTerminal program on the controlling computer (Start > Programs >
Accessories > Communication > HyperTerminal). HyperTerminal is a standard
part of Windows operating system.
3. If you have never used/configured your HyperTerminal before:
•
In the displayed window Connection Description type into Name: Fluke
and press OK.
•
In the next displayed window Connect To select in Connect using: COM1
(or other if you use other com port) and press OK.
•
In the next displayed window COM1 Properties set the right properties.
