B. Introduction

Congratulations on purchasing The Analyst RS422/RS232 Tester.

Because Troubleshooting RS422 & RS232 Interfaces can be so Time Consuming
and Frustrating

Identifying and correcting RS422 and RS232 interface problems just got easier with the
data logging option for The Analyst RS422/RS232 Tester. Capture serial communication
into a non-volatile log file for review and analysis. Data can be captured in both
directions with a timestamp. With the Data Logging Option, Analyst users can upload log
files from the tester to a PC for later review and analysis.

The Data Logging Option makes it even easier to isolate and identify communication
problems by recording test results so that users can complete an entire round of tests,
then study the data whenever it is most convenient, as well as share it with others. The
SEARCH function makes it easy to search through a log file for a user entered data
pattern. Search both forwards and reverse through the log file.

Anyone working with RS232 and RS422 cabling and equipment understands how
difficult and time consuming it can be to track down the problem that is keeping a system
from working. The Analyst is an easy-to-use, intuitive troubleshooting tool that enables
experts and non-experts alike to rule out potential problems quickly and fix the real
problem rather than expending resources on time-consuming trial-and-error methods.

Quickly and easily isolate and identify RS422 and RS232 interface problems — whether
testing cable runs between floors or between buildings, verifying RS422/RS232 signal
paths, chasing down an RS422 to RS232 adapter problem, or troubleshooting
communication problems between equipment.

When to Consult the Analyst:

-Remote production setup: mobile production units, special events

-New studio builds, facility upgrades: new equipment, new cabling

-Maintaining existing facilities and systems

We would like to hear from you. Please let us know how you are using The Analyst and
how we can improve it. Our email address is [e-mail].
