HYPERTERMINAL
DESCRIPTION
HyperTerminal is a terminal emulation program which
resides in the Microsoft Windows environment, and
as such, will normally be found on any computer that
is running Microsoft Windows. HyperTerminal pro-
vides a method by which the end user may verify
conclusively that their Quantum™ controller is func-
tioning properly, and as designed, with respect to ex-
ternal communications to remote devices.
NOTE: Hyperterminal can only be used to test
MODBUS® ASCII. It CANNOT be used to test Al-
len-Bradley or MODBUS® RTU or TCP/IP.
Many times, the Quantum™ controller will be in-
stalled into an environment whereby the end user
wishes to communicate to it, either through a PLC
(Programmable Logic Controller), a desktop com-
puter for the purpose of monitoring/controlling plant
operations through HMI (Human Machine Interface),
or any number of other communications applications.
The purpose of this desired communications typically
involves viewing and changing setpoints, starting and
stopping a compressor, viewing alarm and shutdown
information, and viewing current operating condi-
tions.
When fi rst connecting a Quantum™ panel to a com-
munications network, it would be highly desirable to
determine that all necessary parameters (jumper set-
tings, panel setup, and cabling) are properly met so
that communications may be established quickly with
the Quantum™, so that time is not lost in trying to
troubleshoot a potentially simple problem.
A connection from a Comm port of a computer run-
ning Microsoft Windows can be used to connect to a
serial port of the Quantum™.
SETTING UP HYPERTERMINAL
• You will need to locate either a lap top or desk-
top computer that has Hyperterminal installed.
• Turn on the power for the lap top.
• After the laptop has fully booted, locate the Hy-
perterminal program. (Hyperterminal is usually
found in the Accessories folder). If Hyperterminal
can't be found there, try using the Find File com-
mand, and search the entire hard drive.
• Be aware that the screens that are actually
shown on the test computer may or may not ap-
pear exactly as shown here. Various versions of
Windows can affect the appearance, as well as
whether or not the screen has been maximized,
or if it has been scaled to a smaller size. Re-
gardless of how the screen work appears, the
function of the screen work is what is important,
and that function is not affected by the way the
screen looks.
• Once Hyperterminal has been located, execute
it. A dialog box will appear. You will be prompted
to enter a name for the New Connection. Type
in whatever name you would like to use, Frick®
was used in this example. This name will also
create a fi le once you are fi nished, saving all of
the setup parameters for future use. It is recom-
mended that a name be chosen to re fl ect the
type of Protocol that you will be using as you
may wish to setup for various protocols. Once
you have entered a name, click [OK] .
A new dialog box will be shown asking to select a
Com port (choose the Com port that your commu-
nications cable is attached to, this will normally be
Com-1). The phone number box should be blank.
Click on [OK] .
