If your data file does not use any of the predefined file
extensions, you can wild card the file name by using (*.*) in
the file name box and choosing the appropriate file type.
Navigate the computer or network for the required data file, and select the <OK>
button. Once the file is selected, the File load options screen will appear:
File load options screen
This dialogue provides options for file starting address, device memory destination,
file mode, and data format.
File Load Options
For most file load operations you will accept the default values when the File load
options dialog box appears by clicking on <OK>. However, the File load options
dialog box has four option menus that allow you to customize the file load operation:
x Start address in file
x Destination in memory
x File mode
x Intel/Motorola format

Start address in file:
If a hexadecimal number is placed in the Start address in file box prior to a file load
operation, the load software waits until that address is reached before placing data into
the Optima Ram Buffer.
In Example 1 below, the Start address in file has been set to 300 hex, and therefore
the load software waits until address 300 hex has been reached before placing data
into the Optima Ram Buffer starting at location zero.
Start address in file works for all formats.
Example 1: Start address in file

Destination in memory:
The hex value placed in the Destination in memory determines the starting point in the
Optima Ram Buffer where data will be stored.
Destination in memory works for all file formats.
In Example 2 below the Destination in memory value is set to 800 hex; this causes the
start of the data file to be placed at 800 hex in the Optima Ram Buffer.
