The organization of the menu structure is represented in simplified form in the
following illustration:
The remainder of this section shows you the menus available for this module,
and briefly discusses the commands available to you.
Keystrokes
The keyboard commands on these menus are almost always non-case sensitive.
You can enter most commands in lower case or capital letters.
The menus use a few special characters ([?], [-], [+], [@]) that must be entered
exactly as shown. Some of these characters will require you to use the [Shift],
[Ctrl]
or [Alt] keys to enter them correctly. For example, on US English
keyboards, enter the [?] command as [Shift][/].
Also, take care to distinguish capital letter [I] from lower case letter [l] (L) and
number [1]; likewise for capital letter [O] and number [0]. Although these
characters look nearly the same on the screen, they perform different actions on
the module.
4.1.2 Required Hardware
You can connect directly from your computer's serial port to the serial port on the
module to view configuration information and perform maintenance.
ProSoft Technology recommends the following minimum hardware to connect
your computer to the module:
ƒ
80486 based processor (Pentium preferred)
ƒ 1 megabyte of memory
ƒ At least one serial communications port available
ƒ A null modem serial cable.
4.1.3 Required Software
In order to send and receive data over the serial port (COM port) on your
computer to the module, you must use a communication program (terminal
emulator).
A simple communication program called HyperTerminal is pre-installed with
recent versions of Microsoft Windows operating systems. If you are connecting
from a machine running DOS, you must obtain and install a compatible
communication program. The following table lists communication programs that
have been tested by ProSoft Technology.
