❶

The top line of the screen contains the program’s title and the standard Windows screen options,

allowing the user to minimize the screen, to make the screen smaller or larger, or to terminate the

program.

❷

The next line on the screen is a menu bar. The items marked FILE, EDIT and COMM PORT can be

used to select files and save data, to edit frequencies, and to select the COMM port to which a

decoder card can be attached. Also on this line is the name of the file currently used to store frequen-

cy data.

❸

This is a field containing current frequency data file description. This can be changed as desired,

and it will be saved in the data file along with frequency data in order to provide some assistance

in identifying the source or use of the data.

❹

This is the "Current Frequencies" data column which contains the four values read from the card

attached to the system. Normally, this data is obtained automatically whenever a decoder card is

first attached to the system. Under this column is a button marked "Read Frequencies." Click on

this button at any time to reread the frequencies from the card.

➎

The column marked "Edit Frequencies" contains the four numbers read from the disc file which

can be changed as needed to update the card. Only the entries in this column can be edited,

saved to disc or restored from disc or downloaded to the decoder card. Under this column is a but-

ton marked "Download Frequencies." Click on this button at any time to send the frequencies to

the decoder attached to the system.

➏

Below the two command buttons is a field that indicates the decoder status. When a decoder is

attached and communicating with the system, this field will have a green disc and display

"Decoder is Attached.” When no decoder is attached, or is not communicating, the field will show a

red disc and display "No Decoder Attached."
