the metafile. If the upgrade is successful, how the new image is activated depends on the
commit-mode specified in the metafile (see the Speedway Revolution Upgrade Guide).
If the reader is in auto mode during the execution of this command, it is possible that the reader
is currently retrieving the metafile or performing an upgrade. In these instances, this command
will return “Previous-Command-In-Progress.”
4.2.2.4 Config Image RetrieveMode Command
This command sets the reader’s metafile retrieve mode and, if set to
auto
, the retrieval period as
described in Table 4-4. When the retrieve-mode is set to manual, the reader will take no upgrade
actions. To perform an upgrade in the manual mode the user must issue a
config image upgrade
command, directly downloading an upgrade image.
Table 4-4 Config Image RetrieveMode Command Parameters
Command Argument Format Description
manual enum In manual mode the user must manually specify a new
metafile URI or manually command an upgrade. retrievemode
auto <period> enum,
integer
In auto, the reader periodically retrieves the metafile
from the most recent metafile URI at the rate specified
by the <period> in minutes. The retrieve period is used
only until the reader retrieves a valid metafile, at which
time the retrieve period contained in the metafile is
adopted.
Usage: config image retrievemode manual
Usage: config image retrievemode auto <period>
<period> is the duration between successive retrievals of the metafile
(in minutes) from the most recently specified URI.
If this command results in a change from
manual
to
auto
, or a change of
retrieve-period
while the
current mode is
auto
, the reader immediately attempts to download a new upgrade configuration
metafile using its current metafile URI.
4.2.2.5 Config Image Upgrade Command
This command is used to instruct the reader to directly download an upgrade image file and
perform an immediate upgrade. Upgrade image files are stored on a file server and retrieved by
the reader from the location identified by the URI.
Usage: config image upgrade <URI>
Upon receiving this command, the reader downloads the image file and if the file is valid and
eligible, performs the upgrade. When this command is used, the upgrade will always be
performed even if the upgrade version matches the current version. If the upgrade is successful,
the new image is not activated until the user reboots the system.
