Firmware Update; Restore Button - Usl LSS-100P Installation And Operation Manual

To calibrate the SPL meter, place a sound level calibrator, such as the Reed SC-05 over the LSS-100P
microphone. Set the sound calibrator to 94dB. Key 94 into the Measured SPL field, then click the
Calibrate Microphone button.
The remainder of the screen includes information to aid in the production test of the LSS-100P. It can be
ignored while doing field calibration of the LSS-100P.

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 - LSS-100P firmware update page. 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.
