5. PROGRAMMING YOUR SERIAL DEVICE

OVERVIEW

Digital panel meters, counters, timers and transmitters are easily programmed via their serial
port using Windows-based Instrument Setup (IS) software, which provides a graphical user
interface and is available at no charge. This software allows uploading, editing, downloading
and saving of setup data, execution of commands under computer control, listing, plotting and
graphing of data, and computer prompted calibration. Digital panel meters, counters and timers
can also be programmed via their 4-key front panel as explained in their respective manuals.
For Ethernet, please see our separate Ethernet Manual.

GETTING STARTED WITH INSTRUMENT SETUP SOFTWARE

To install IS software, download the file

instrument.exe

from our website, double-click on the

file name to extract three files, double-click

on setup.exe

, and follow the prompts. To launch IS

software, press

. Establish communications by selecting

matching settings between the instrument and PC, and click on

Establish

. Once communica-

tions have been established, click on

Main Menu

.

The best way to learn IS software is to experiment with it. From the Main Menu, click on

Get

Setup

to retrieve (or get) the existing setup data from your device. Click on

Put Setup

. Programmable

items will only be displayed if the appropriate hardware has been detected, such as the dual
relay option for meters. Pressing the

F1

key at any time will bring up detailed help information.

An analog output is defined in two steps. The input to the device is first scaled to a digital
reading in engineering units, and this reading is then scaled to the analog output. The digital
reading is also used for setpoint control and can be transmitted as serial data.

ADDITIONAL FEATURES

The Commands pull-down menu allows you to execute certain functions by using your

computer mouse. The

Commands

pull-down menu will be grayed out unless a

Get Setup

has

been executed.

The Readings pull-down menu provides three formats to display input data on your PC

monitor. In all formats, use the

Pause

and

Continue

buttons to control the timing of data

collection, then press

Print

for a hardcopy on your PC printer. List presents the latest digital

readings in a 20-row by 10-column table. Plot generates a plot of digital readings vs. time in
seconds, like an oscilloscope. Graph generates a histogram, where the horizontal axis is the
reading and the vertical axis is the number of readings.
