Firmware Update
USL may offer firmware updates to add features to the LSS-100P. Firmware updates are delivered as a
“hex” file. To install the update, click on “Update Firmware Page” on the “Configuration Page.” The
firmware update page is shown in Figure 21. Note that some firmware updates may result in a change in
log format. For this reason, this page includes a “Clear Log” button. This button can also be used to clear
the log for other reasons.

Follow these step-by-step instructions to do a firmware update:
1. Use the browse button to select the hex file to be loaded into the LSS-100P.
2. Press “Update Main Processor.” The green LED on the LSS-100P will flash as the new firmware is
installed. After the new code is uploaded to the LSS-100P, the browser will return a “Connection
Reset” message. This happens when the LSS-100P reboots with the new firmware.
If a firmware update is interrupted, it is possible for the LSS-100P to cease operating. To restore the
factory firmware (allowing another attempt at the update), hold down the restore button as power is
applied to the LSS-100P. If the button is held for about 1 second before and 1 second after power is
applied, the factory firmware will be reloaded and system configuration will remain unchanged. The
green LED flashes as the firmware is reloaded. Once the system is up and running, pressing the restore
button will restore the default IP address (169.254.1.6).
Restore Button
The restore button on the LSS-100P serves two purposes:
1. If the restore button is momentarily pressed while the LSS-100P is operating, the IP address is
temporarily changed to its default IP address (169.254.1.6). It will stay at this IP address until the
next power cycle.
2. If the restore button is held down 1 second before applying power until 1 second after applying
power, the factory firmware is reloaded. This can be used if a firmware update fails and leaves
the system inoperable. The green LED will flash as the firmware is reloaded. No configuration is
changed in this process. The unit will remain at the same IP address.
