It is possible to copy or delete set data in units of lines using the Data Copy and Data Delete buttons
in the lower part of the application software screen.
Data copy
When the Data Copy button is pressed, the following window opens. Specify the original line to becopied and the destination line.
Press the OK button to copy the specified line. If the Cancel button is pressed, the window closes
without copying the line.

When the line is copied, the pattern numbers following the destination line are incremented. If thenumber of lines exceeds 24 after increment, the excess line is deleted automatically.
<Example> Copying the 4th line on the 2nd line

Increments.
Data delete
When the Data Delete button is pressed, the following window opens. Specify the line to be deleted.
Press the OK button to delete the specified line. If the Cancel button is pressed, the window closes
without deleting the line.

8. SYSTEM FILES
Data set with the application software are stored in system files with “.DAT” extensions and reflected
upon the CG-971 as shown below.
Natural image data used in the allowable condition by the user are stored in files with .BMP
extensions, which have the same file names as the system file names. A set of the system file andnatural image file having the same names are stored in a CF card. It is unnecessary to create
a .BMP file if the pattern setting of the system file has no natural image pattern.
Insert the CF card into the CG-971 in the power off condition and turn on power. The files areloaded into the CG-971. Once the system file is loaded, it is unnecessary to insert the CF card then.
※ Always give the same file name within eight half-size capital alphanumeric letters to both
files. The CF card format should be FAT12, FAT16 or FAT32.
※ We uses 2GB or smaller-capacity CF cards made by San Disk Corporation to check
operations of the CG-971. It will not warrant the performances if the user uses other CF
cards.

8-1. System file selection
When a CF card is inserted into the CG-971 in the power off condition and power is turned on then,the system file selection screen appears and the user may select an intended system file. If the CF
card contains a single system file, the system file selection screen does not appear and the systemstarts up. If it is necessary to change the system file, turn off power once and turn it on then or send
the system file selection (FSEL) command through the interface.
System file selection screen
SYSTEM1.DATLOAD

SYSTEM1.BMP.DAT files in the current of the
CF card are displayed insequence.

When this button ispressed in selection, thesystem starts up.

System file name is displayed on the first line.
.BMP file of the same name, if any, is displayedon the second line.
28Selecting system file through interface
It is possible to select a system file through the RS-232C or GP-IB interface when the system fileselection screen is displayed.
Even after the system has started up, if another system file name is specified using the system fileselection (FSEL) command, the system starts up again using the specified system file.
［Interface Selection (for selecting system file immediately after turning on power)］
It is necessary to select an interface only in the case where a system file is selected immediately after
turning on power. If the system file need be changed after the system has started up, an interface
has already been specified and interface selection is not needed.
The RS-232C interface is normally selected. If a file with a name “GP-IB (address No.).INI” is stored
in a CF card the GP-IB interface is selected. This file name must be written in capital alphanumericletters. If there are several files, the file with the smallest address number is selected. The file size
may be 0 bytes, since data written in the file are ignored.
When selecting RS-232C: No specification is needed, in particular.

When selecting GP-IB: Store a file with a name “GPIB (number.).INI” in a CF card.
<Example> File name GPIB5.INI ⇒ Selects GPIB address 5.

［System File Selection］
Sending the MFILE? command outputs the names of all system files contained in the CF card in a list.
When the system file selection command (FSEL_file name) is sent then, the system starts up again
using the selected system file.
※ _ (The under-bar shows a space.)<Example> When system files SAMPLE1 to SAMPLE3 are stored in the CF card and SAMPLE2 isselected
Sending MFILE？ （command）

System file names in CF card are displayed.

SAMPLE1, SAMPLE2, SAMPLE3
Sending FSEL SAMPLE2 （command）

System file SAMPLE2 is selected.

(System restarts using SAMPLE2)
