Instructions for upgrading Firmware are as follows.
1. You will need valid ELPRO 915U-2 Firmware upgrade files. Contact ELPRO
Technologies for the latest version. Files must not be renamed, compressed,
or zipped.
2. You will also need a dedicated USB Flash drive which needs to be formatted
and completely free of any other file. Copy the firmware files to the Flash
drive making sure they are in the root of the drive and not in a sub directory.
3. Before upgrading the firmware it is good practice to backup the existing
configuration. Go to the “System Tools” webpage and save the configuration
by selecting “Read Configuration File” and when the XML file is displayed
press <CTRL> F5 to refresh the cache and select “Save As” or “Save Page
As” on the File menu to save the XML as a file.
4. To upgrade, remove the “Configuration Panel” from the side of the module
and plug the Flash drive into the USB port. If the module is mounted on a DIN
rail with other I/O modules it will need to be removed to gain access to the
side panel.
5. Power cycle the module to begin the upgrade process. As the module powers
up it will recognise that a Flash drive has been installed and start upgrading
the firmware. You will see the normal boot up LED sequence (see 3.2
“Indications” for details) however the orange indication will be on for longer.
DO NOT remove the Flash drive or interrupt the power to the module while
this is happening. If the upgrade process is interrupted module could
become unserviceable and will need to be returned to ELPRO for repair.
Upgrade will take approximately 2 minutes and 40 seconds, 120 seconds
over the normal boot time. When update is complete (Solid Green PWR
LED indication) remove the flash drive.

6. The upgrade process will clear the module flash so you will need to load the
configuration file back into the module. To do this select “Write Configuration
File” from the “System Tools” menu. Browse for the saved XML file and when
loaded press Send and then Reset.
