12. Transferring the application and the protocol to a
PCMCIA card
Import/export file
If a PCMCIA read/write card is available on a PC that has been loaded with the XBT-L1000 software, the application can be directly written on the card provided for the terminal. The Transfer/Import-export file menu is used to select the name of the PCMCIA unit.
Before performing an exportation to a PCMCIA card, it is necessary to define import/export file location (transfer menu, import/export file).
The application must be exported to the PCMCIA inside a directory called "appli". If it does not exist, the XBT-L1000 software will create this directory after performing "transfer menu / import / export file".
The name of the PCMCIA card as a hard PC unit is given automatically by the PC operating system (Windows 95, 98, NT).
In other cases (to a hard disk for example), the file name and its location can be different.
XBT-L1000 -> PCMCIA card export
To export the application, select the Transfers/Export/ to import/
export folder menu. Insert PCMCIA card at the location provided on the terminal.
PCMCIA -> XBT-L1000 card import
To import the application, insert the PCMCIA card into the PC and then the Transfers/Import/from import/export folder menu.
Before, use the Export/to import/export folder function to select the hard unit from which to import the application.

13. Updating the application
Note
When an application that has been saved under an earlier version of the
XBT-L1000 software is opened using a later version, the user will be prompted to have the software update the application to the later version.
This operation is used to update new system page formats and enables the designer to incorporate the enhanced functions of the new version into the existing application. Therefore, It is strongly recommended that the user perform the update.
The model pages for application, alarm and help pages are not updated automatically. Thus, the alarm strip and the status line may have been re-located, deleted or modified by the designer.
B
Updating the model pages:
1. Perform the updating proposed by XBT-L1000.
2. Create a new model for each type of page (application, alarm, help).
3. Delete the required elements (alarm strip, status line) from the existing models.
4. Cut/paste the elements required from the new models to the existing ones.
Once updated, it is not possible anymore to open the application with the XBT-1000 version used to create the version (version n).
