“
Disable All” Button
:
Clicking on this button disables all the check boxes on
the screen. This operation is done to inhibit all the fields to be written to (or
read from). Alternatively, the end user can individually deselect a given field

“
Query” Button
:
Clicking on this button performs a read operation on all the
fields that have their check box enabled. Once clicked, all the selected fields
will be read back reflecting their current configuration.

• “Update” Button: Clicking on this button performs a write operation on all
the fields that have their check box enabled. Once clicked, all the selected
fields will be written to with the value denoted in their respective field (text

• “Store All Setup Pages” Button: Clicking on this button stores all setup
pages, even if they are not shown.

“
CLR” Button:
Clicking on this button clears out all fields on the screen,
regardless of whether the fields’ check boxes are selected or not. This button
proves useful when the end user wants to verify that a write operation has
been correctly performed. An example scenario would be to 1) enable all
fields, 2) change desired field(s), 3) perform an ‘Update’ (write) operation, 4)
perform a ‘CLR’ operation and 5) perform a ‘Query’ operation. As a result of
the ‘Query’ operation, the fields on the screen should all update to those
values that were written during the ‘Update’ operation.

“
Load Group” Button:
The data structure of the M2T is organized into
“Groups” of selected fields. A Group contains the following fields (refer to
Figure 7 above): Carrier Mode, Modulation Mode, COFDM Bandwidth,
COFDM mode, Guard Interval, Modulation FEC, Video Frame Size, Video
Frame Rate and Input Mode.
Clicking on the ‘Load Group’ button loads the selected Group to be operated
on by the M2T. A Group can be selected by selecting Group Name under the
pull down text box “Group Name (16Chars)” or by its Group Number under
the “Group No” pull down text box.

Clicking on the ‘Load Group’ button loads the selected Group to be operated

pull down text box “Group Name (16Chars)” or by its Group Number under
the “Group No” pull down text box.
Note: After selecting a group by either its’ group number or group name
you must click on the “Load Group” button for the group to take effect.
The M2T allows up to 20 group types to be stored in the non-volatile memory
each with its’ own unique Group name and associated Group Number. The
unit is provided with 20 established groups (see appendix C) in which the
parameters have been carefully chosen for optimal performance.

The end user has the ability to change the name of a group (limited to 16
characters), and to change the parameters of the fields associated with a
