Loading Configuration Files and Databases

Certain files may take extended periods of time to load directly from a PC to the 920i. A flash drive is recommended for fast loading times. When using multiple 920i units, it is recommended to create a folder matching each ones unit ID number. When loading configuration files, the unit will load the file contained in a folder matching its UID# (the default UID# is 1). If a folder matching the UID is not found, the unit will load the first file found.

If loading a configuration file from a UID subdirectory, ensure the configuration file does not change the unit ID. Otherwise, a COD file in that subdirectory will not be recognized until the UID is manually reverted to its original number.
File names are limited to eight characters.

1. Using a PC, copy the desired configuration file to the flash drive.

2. Insert the flash drive to the 920i’s Type-A USB connector.

3. Press the USB softkey.

4. Select Drive and press Enter.

7. Select Load Configuration and press Enter.

Loading Database Files

File names are limited to eight characters. If loading a database file, be aware the indicator uses the alias name and a .db file extension when saving database files.

1. Using a PC, copy the desired database file to the flash drive.

2. Insert the USB flash drive into the 920i’s Type-A USB connector.

3. Press the USB softkey.

4. Select Drive and press Enter.

5. Select Load All Databases (*.db) and press Enter.

Saving Configuration Files and Databases

Certain files may take extended periods of time to save directly from a PC to the 920i. For fastest save times, using a flash drive is recommended.

When saving a configuration file, the indicator will attempt to save to a folder matching its UID number (the default UID# is 1). If a folder is not found, the file will be saved to the drives root directory and overwrite any existing files matching its UID# followed by the .920 file extension i.e., 1.920i.

When the 920i AC/DC Indicator saves a database, it will use the alias name and a .db file extension.

1. Insert the flash drive into the 920i’s Type-A USB port.

2. With the indicator in weigh mode, press the USB softkey.
   If the USB softkey is not displayed, see Section 3.3.2 on page 12 and Section 1.2.2 on page 4.
