6.1.3 Vacuum Fluorescent Display (VFD)
The displays for the initially-released chassis and the current
production unit differ as follows:

(RIGHT) Vacuum Fluorescent Display (VFD) – Current Production Unit
DT-4503C-2
SW VER 1.2.3 SN012345678
See Figure 6-1, Item 2. The VFD is an active display showing two lines of 24
characters each. It produces a blue light with adjustable brightness. On most
menu screens, you will see a flashing, solid-block cursor that blinks at a once-
per-second rate. This indicates the currently selected item, digit, or field:
CONFIG MONITOR FAULTS
PRE-SELECTS UTILITY
Where this solid block cursor obscures the item under edit (e.g., a numeric field),
the cursor automatically changes to an underline cursor:
IP Address/Range:
192.168.001.006/24
To prevent the display from becoming burnt by a constant image, the unit
employs a screen saver feature that activates after one hour. This message
constantly scrolls and wraps across the screen. The top line displays the AID (the
user-defined name for the unit); the bottom line displays the message “Press
any key…” as shown:
Circuit ID:-------------
---Press any key...
Press any key to restore the previously active screen.
