CHAPTER 4: POWERING-UP AND TESTING
Accessing WESMAINT II+ using a terminal
You can use a VT100-compatible terminal or a terminal emulation program to directly
access the WESMAINT II+ facility. SGConfig's Terminal Emulator is an example of a suitable
terminal emulation program.
For further information about using WESMAINT II+ software to perform any of the test
procedures in this section, refer to the WESMAINT II+ User’s Guide.
Terminal Emulation
Microsoft Windows™ HyperTerminal can be used for terminal emulation but it is NOT
recommended because code and configuration file download times are considerably
increased.
The program Tera Term for Microsoft Windows™ does not have these limitations and is
therefore recommended as a terminal emulation program. It can be downloaded from the
Internet.
SHELL
The SHELL is a debugging and diagnostics tool that is accessible as a menu selection in
WESMAINT II+, or from a basic login prompt if WESMAINT II+ is not available.
The approved method of using the diagnostic tools of the SHELL is through the front RS232
port.
