RS 232 Overview
Introduction
RS-232 is an industry-standard method of sending data back and forth between two pieces of equipment.
With the Model 2411B, a computer can remotely control the instrument, download waveform data and
upload waveform data.This overview explains the interface requirements, 2411B setup, how to verify
communications and the command syntax structure.
Interface Requirements
All IBM (or IBM compatible) personal computers (PCs) should be equipped with at least one serial
interface port. It may be either a 9-pin DB-9 or a 25-pin DB-25 connector. If desired, a cable may be
constructed as described in Chapter 7. Most any software which defines communication protocols may
be used. This includes the programming languages Quick Basic, GW Basic, Visual Basic, Quick C,
Turbo C and Turbo C++. Communications programs such as ProComm, a "shareware" version, are also
usually acceptable. A "local echo" feature is helpful to monitor your typing.
To control the generator from the serial port
Hardware Handshake
This is the only handshake available on the 2411B.
With hardware handshaking, flow control of data to/from the instrument is controlled by the
DTR/CTS lines of the RS-232 interface.
Sending data to 2411B:
Instrument will turn the DTR line off (-12V) when the instrument buffer fills to 200 characters.
Instrument will turn the DTR line on (+12V) when the instrument buffer empties to 80 charac-
ters.
Receiving data from 2411B:
Instrument will stop sending data when the CTS line is off and resume sending data when it is
on.
