In this field (available only in the TxPORT mode of opera-
tion), the NEAR or FAR unit is selected by toggling the
spacebar and pressing ENTER. When the far end is
selected, the remote communications channel allows access
to the far-end unit parameters as if the user were connected
locally. The 4001 continually monitors its remote end for
alarm and status conditions and reports these locally.
Messages: Diagnostic messages are displayed at the bot-
tom of the screen. They reflect Alarm Status and Loop Sta-
tus for the unit.
Cursor Controls
The terminal interface employs a highlighted cursor to make
menu and field selections. The cursor is moved in different
ways depending on the terminal emulation program used.
Most programs allow the use of the TAB and SHIFT+TAB
keys, and some allow the use of the arrow keys. Once a field
is highlighted, it is manipulated as described in section below.
An alternate set of cursor control commands is provided for
keyboards which lack standard keys or have an incomplete
set (Table 4-A). Enter an alternate command by pressing its
letter key while holding down the CONTROL key. Alternate
commands and keyboard commands may be freely mixed.
Field Types
Each screen is made up of fields. The two basic field types
are user selectable and display only. If the highlighted cur-
sor can be moved to a field, it is a user-selectable field. All
other fields are display only. User-selectable fields permit
the user to make changes or execute commands.
Fields without brackets or parenthesis are display only and
cannot be changed on the screen. Most user-selectable fields
are enclosed in brackets or parenthesis and are described in
the following paragraphs.
Fields enclosed in brackets [ ] offer a list of selections.
The selections may be toggled by pressing the spacebar.
Each time it is pressed, a new item appears. When the
appropriate choice is displayed, press ENTER to select it.
Fields enclosed in parenthesis ( ) are manipulated by one
of the following two methods:
• Pressing ENTER on such fields as (Reset) and (Start Test)
to execute the function.
• Typing input in the form of letters, numbers, or both. The
most common type of field in parenthesis accepts typed
input. Typing characters when the field is highlighted
replaces the current entry with the new characters. To edit an
existing entry rather than replace it, use the right arrow key
to move the cursor to the point that needs editing, then insert
or delete characters as necessary. Typed input is always
inserted rather than typed over. If the field is full, however,
at least one character must be deleted to add another.
Press CONTROL+U to redisplay or refresh a
local or remote screen. Press CONTROL+T to
toggle from the remote screen to the local screen.
Main Menu Screen
The Main Menu (Figure 4-1) lists the functional user acces-
sible menus. To activate any menu, highlight the desired
selection and press ENTER. All menus may be exited by
pressing Escape. If the Main Menu is exited, the terminal
interface program terminates. This is a valid way to end a
user session. If any other menu is exited, the previous
screen is returned. The menu structure (Figure 4-2) shows
all the screens accessible from the Main Menu
