Appendix C

NOTICE

Because of the nature of the internal connections of some secondary injection-style 
relay-test sets, a ground-loop condition can develop when 

both

 the test set and a PC are 

connected to an ac wall outlet . The ground-loop condition may damage the PC data port . 
Always isolate the PC by running it on an isolated ac supply or by running the PC on its 
battery packs .

Using Terminal  
Emulator Programs

The procedures for starting and using terminal­emulator program will vary depending 
on the specific terminal­emulator program. A simple terminal­emulator program was 
included with every copy of Microsoft Windows. 

NOTICE

Windows Vista, Windows 7, and Windows 8 do not include a terminal-emulation program . 
Users must select and install a terminal-emulator program to be able to communicate 
with the S&C Overcurrent Control . S&C recommends downloading one of two terminal-
emulator programs listed below .

Manufacturer:  Schweitzer Engineering Laboratories, Inc.
Program: 

AcSELerator QuickSet 5030

Website: www.selinc.com/sel­5030.htm
Note: 

This software is available to download for free.

Manufacturer: Hilgraeve
Program: HyperTerminal
Website: www.hilgraeve.com/hyperterminal.html
Note: 

This software is the same software supplied with previous versions  
of Microsoft Windows. It is available for purchase.

Basic instructions for the terminal­emulator programs “HyperTerminal” (which comes 

with Windows 95, 98, 2000, NT, ME, and XP, and available for download for Windows 
Vista, 7, and 8 users) and “AcSELerator QuickSet 5030” (available for download) are 
provided on page 26.

HyperTerminal

For Windows 95, 98, 2000, NT, ME, XP, Vista, 7, and 8:

Step 1

Click on the 

Start

 button.

(a) For Windows 95, 98, and ME select 

Programs

 and then 

Accessories

. In the  

Acces sories

 folder, select the 

HyperTerminal

 icon. Then double­click on  

Hypertrm.exe.

(b)  For Windows 2000, NT, and XP select 

Programs

, then 

Accessories, 

then 

Commu-

nications 

(or 

HyperTerminal

). Then select the 

HyperTerminal

 icon.

(c)  For Windows Vista, 7, and 8 open the 

HyperTerminal

 program from its file location  

(probably on the desktop).

Step 2

A dialog box will then ask for a “connection description.” This is a file that will be saved in 
the 

HyperTerminal

 folder with its own name and icon. It stores the appropriate set tings 

for connecting to the S&C Overcurrent Control so they do not have to be entered every 
time. In the “connection description” dialog box, enter a name for this file (for example, 
“Vista”).
