Figure 1 on page 3 shows the many
ways you can use the 232 Monitor
Plus.

Troubleshoot printers to
eliminate handshaking
problems.

quality of a leased line.

Monitor Plus from any ANSI-
standard CRT terminal.

connected on all pins. So you may elect

avoid disrupting circuits.

allowed in the Configure Menu.

The 232 Monitor Plus Keyboard
Each key of the 232 Monitor Plus
can serve three distinct functions.
Thus, there are three ink colors on
most of the key labels:
• RED= Main text (keys that
appear on a standard keyboard)
• GREEN=Subtext
• WHITE=Upper text
(commands)
Brackets [ ] on the Screen
To conserve screen space, the 232
Monitor Plus references command
keys (the white "upper" text on a key)
by the letter of the alphabet that
resides on the same key (the key's
red letter). The alphabet letter is
placed in brackets [ ] to indicate it
is a reference to the command that
shares the key with the alphabet
letter.
For example, the command
PULSE CAPTURE
would appear on screen as the letter
U enclosed in brackets, as shown
below:
[U]
