The RAM VIEW function is used to display the internal data memory (RAM)
in the character inserter. This display is used to aid in troubleshooting
problems in the field and should not be used during normal operation or
maintenance procedures. To make use of RAM VIEW you need to have
information on which RAM locations to view. This information is available
from Evertz technical support staff if you are experiencing difficulties.
The RAM VIEW item of the Toolbox DEBUG menu is used to turn on RAM
VIEW mode. (See section 5.5 for a full description of the DEBUG menu).
When you exit the Toolbox menu with RAM VIEW turned ON, a special
window appears at the top of the screen which indicates that you are in
RAM VIEW - ENTRY MODE. A RAM view display is located near the
bottom of the screen that indicates the information as follows:
S =
P =

In RAM VIEW - ENTRY mode, the normal operation of the keyboard is
suspended. The following keys allow you to change the data being
displayed.
