1. RS232C Overview
Introduction
RS-232 is an industry-standard method of sending data back and forth between two pieces of equipment.
With the equipment, a computer can remotely control the instrument, download waveform data and
upload waveform data. This overview explains the interface requirements, instrument setup, how to
verify communications.
Interface Requirements
All IBM (or IBM compatible) personal computers (PCs) should be equipped with at least on serial
interface port. It may be either a 9-pin DB-9 or a 25-pin DB-25 connector. An 8-foot 9-pin cable is
included with the instrument. 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.
