The version of DDL.EXE included in the VX 680 SDK allows you to change the
default drive and file group for a direct download by preceding the filename(s) on
the DDL command line with a special filename. The syntax is as follows:
SETDRIVE.<drive letter>
where, drive letter is I: (default) or F: , and/or
SETGROUP.<group number>
where, group number is 1–15.
For example, the command-line entry
DDL SETDRIVE.F cardco.lib SETDRIVE.I SETGROUP.15 card.dat
downloads the executable file cardco.lib into the F: drive of the selected target
group and the data file card.dat into Group 15 I: drive. (Because drive or group
settings apply to all files that follow in the list, it is necessary to use SETDRIVE.x
to reset the drive from F: back to I:.)
If you are using this DDL.EXE method, zero-length SETDRIVE.x and
SETGROUP.n files do not need to exist as files on the download computer.
When performing an operating system download, you must download the OS files
into Group 1 I: drive and not into F: drive memory or into another file group.
OS files are downloaded into Group 1 I: drive because it is not possible to
download these files directly into Group 0. OS files are redirected to Group 0
depending on if you perform a full or partial download (see
For full OS downloads, the redirection of OS files into Group 0 is performed
automatically, after the terminal restart, and as part of the download
procedure.
For partial OS downloads, OS files are redirected from the I: drive of Group 1
into Group 0 on manual terminal restart by selecting the appropriate Verix
Terminal Manager menu option.
A downloaded OS is processed and authenticated while stored in Group 1 I: drive.
As the files are authenticated under the authority of the certificates and signature
files included in the OS download package, they move automatically into Group 0.
This process, which usually takes a few moments, is completely transparent
during the download procedure.
In a back-to-back application download, all application files stored on the sending
terminal—in both file systems and in all file groups—transfer to the receiving
terminal in a single operation.
For this type of download, you must select Group 1 as the target group on the
sending and receiving terminals. When you initiate the download on the receiving
terminal, all application files, as well as all special files required for file
authentication and terminal configuration settings on the sending terminal,
download to the receiving terminal.
