Programming Keystrokes
When the XMO2 is in Operate Mode , it ignores all keystrokes except
the [ENTER] or [Y] keys. When the [ENTER] or [Y] key is pressed, the
computer terminal displays Enter Code: and waits for the user to
enter the correct passcode for access to the User Program . While the
passcode is being entered, the XMO2 continues to update the data
display, alarm status, and recorder output.
If the correct passcode is entered, the XMO2 enters Programming
Mode in the menu corresponding to the passcode used. While the
XMO2 is in Programming Mode , data collection is suspended, and
alarm status and recorder outputs are held at their current values.
While the XMO2 is in Programming Mode , the computer terminal
keys are divided into the following three groups:
•
Yes/No Keys: The [Y] key (upper or lower case) is used to select a
displayed menu option or to confirm a numeric entry. The
[N]
key
(upper or lower case) is used to scroll forward to the next menu
option or to clear a numeric entry.
•
Selector Keys: The [
←]
and [
→]
keys are used as selector keys.
The [
←]
key is used to step backward through a displayed list of
menu options, or as a backspace (erase) key during numeric entry.
The [
→]
key is used to step forward through a displayed list of
menu options. It is equivalent to the
[N]
key.
•
Data Entry Keys : The [0...9] , [-] , and [.] keys are used to enter
numeric values.
Menu Navigation
During programming, each menu prompt is represented by a two-line
display. While a menu prompt is being displayed, the top line of the
display shows the title of the current menu in capital letters
(
CURRENT MENU
), and the bottom line shows the current menu
option followed by a question mark (
Menu Option?
). To respond to a
menu prompt:
•
Press
[Y]
or
[ENTER]
to select a displayed option
•
press [N] or [
→]
to move on to the next option
•
press [
←]
to move back to the previous option
The XMO2 menu options are circular. That is, pressing [N] at the last
option in a list returns to the first option in the list.
As an aid in navigating through the XMO2 menu options while
following the instructions in this chapter, see Figure C-1 on page C-1
for a flow diagram of the
Basic Menu .
