13.6.1 Remote Firmware Upgrade – LMU 1000™

The LMU-1000™ can be forced to do a remote firmware upgrade by use of an SMS

Message. The message is formatted as follows:

!R8 <new version number> [<URL of server>]

The “new version number” is the 3-character version designation of the software to be

downloaded

The [<URL of server>] refers to the server and file which the LMU requests to download.

This is an optional field which will default to URL of the Maintenance Server (Parameter ID

2320, Index 0). The filename should combine the version with the current App ID to build a

file name for the update it is seeking to download. The format for the filename is:

LMU_<AppId>_<version>.jar (i.e. ‘LMU_086_12a.jar’).

The complete command would look similar to the following:

!R8 03d http://puls.calamp.com/dnld/lmu-086-03d.jar
