Speedway Reader IPJ-R1000 for Gen 2 UHF RFID

If the reader is in pull 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 may return “Previous-Command-In-Progress”.

Note: a fallback will utilize all the old configuration settings, including the upgrade metafile settings as if the upgrade to the

newer image was never performed—which may trigger an immediate upgrade. If the URI of the old metafile is known and an

immediate upgrade is not desired, the user should remove or rename the old metafile before performing a fallback.

Usage: config image fallback

7.4.2.3. config image metafile Command

This command takes the Universal Resource Identifier (URI) of the upgrade configuration metafile as the parameter. It

commands the reader to perform an upgrade using the metafile identified by the URI.

Usage: config image metafile <URI>

Upon receiving this command, the reader updates its local upgrade configuration URI, retrieves the upgrade configuration

metafile, and performs the upgrade in accordance with the metafile. If the upgrade is successful, how the new image is

activated depends on the commit-mode specified in the metafile (see Section 6.1).

If the reader is in pull mode during the execution of this command, it is possible that the reader is current retrieving the

metafile or performing an upgrade. In these instances, this command may return “Previous-Command-In-Progress”.

7.4.2.4. config image retrievemode Command

This command sets the reader’s metafile retrieve mode and, if applicable, retrieve period. See Table 7-3. When the retrieve-

mode is set to push, the reader will take no upgrade action. To perform an upgrade in this mode the user must issue a config

image upgrade command to directly download an upgrade image. (See section 7.4.2.5).

Usage: retrievemode push

retrievemode pull <period-minutes>

<period-minutes> is how often the reader pulls the metafile

from the most recently specified <URI>.

Table 7-3 “config image retrievemode” Command Parameters

Argument Options Format Description

mode

<pull

| push>

STRING

When the mode is pull, the reader periodically retrieves the metafile

from the most recently set metafile URI at the rate specified by the

retrieve-period. In push mode the user must manually specify a

new metafile URI or manually upgrade the file to perform the

upgrade.

retrieve-period INT

Interval of pull in minutes — only applicable when mode is pull. This

retrieve period is used only until the reader retrieves a valid metafile, at

which point the retrieve period from the metafile is adopted.

If this command results in a change from push to pull, or a change of retrieve-period while current mode is pull, the reader

immediately attempts to download a new UConf metafile using its current metafile URI.

7.4.2.5. config image upgrade Command

This command is used to instruct the Speedway 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 Speedway reader from the location identified by

the URI.

Usage: config image upgrade <URI>
