Uso Data View

Introduction

Caterpillar DataView is a portable diagnostic tool that allows data, measured by sensors
temporarily installed on Caterpillar products, to be viewed on a Personal Computer (PC). It
allows many of the individual hand-held diagnostic tools currently being used by service
technicians to be replaced with a single unit. DataView can be used with all Caterpillar
products, bothnew and old.
Caterpillar DataView consists of a portable hardware instrument (DataView hardware) which
connects to a standard PC via the parallel printer port and a Windows-based software program
(DataView software) that runs on the PC. The DataView software program provides setup,
digital displays, graphs, and data logging of the measurements being taken. The hardware
accepts up to ninestandard Caterpillar sensors. A parallel port on DataView is provided for
operating a printer when DataView is attached to the PC. DataView is powered from the
internal batteries for portable use, or external power.

Software Features
Thefollowing screen views show how the different tools look in the DataView software.

Setup Tool

The Setup Tool helps you select what sensors are available and tells DataView what sensors
you will be using on each channel. It is the first window you will see after connecting the
DataView hardware and software. The Setup Tool lets you specify what type of sensor is
attached to each channel.You assign units (Metric or English) to the channel, assign unique
names for easy identification, set low and high alarm values, set display rate, choose a position
probe polarity, and set the filter level to one or more channels. As you set up channels the
current output of the channel’s sensor is visible on the setup screen. You can set up channels
for immediate or future use. Setups createdfor future use can be saved as a permanent group.

Defining Sensors
To select a sensor and set up a channel, double-click on any channel and the Define Channel
box will appear as shown below.

If you install the DataView software on your PC, you can try this even if the DataView hardware
is not connected.
From the list of available sensors, select one by clicking on it. You can thenselect the units and
change any of the names or values in the boxes. When you select OK, that sensor will be
installed on the selected channel.

Status Tool

The Status tool shows the real-time values for each channel. As well as a digital value, it can
also display an analog bar graph for each channel. A “Zoom” feature provides easy reading
from a distance.

Setup Logger

The Data Loggertool allows information from all channels to be recorded on a PC memory card.
The PC memory card provided with DataView has a 2 MB capacity, but larger cards up to 16
MB can be used. The recording can be started manually or automatically and samples can be
taken up to 1000 times per second. This allows the recording of fast events such as
transmission clutch shift times.

Graph Viewer
TheGraph Viewer tool combines both Strip Chart and Histogram (Bar Graph) tools. You can
choose between logged data files on the PC, real time from the DataView hardware, or logged
data files on the DataView hardware. Once the data source is selected, you can select either
the Strip Chart or the Histogram graph type. A Graph Definition Wizard allows you to select
exactly how you want to set up...
