Updating Transmitter Firmware: ULSX‐CAL software can also be used to update firmware inside the Series
ULS transmitter. This feature allows the transmitter to be updated when new features are added. First open
ULSX‐CAL with an Series ULS transmitter connected and the latest version of ULSX‐CAL installed to your PC.
Click on the “Updates” Tab and then click on “Select Program” to select the firmware update.
Select the latest version of the firmware file and click on OK.
Confirm that the address is correct and then click on “Update Sensor” to begin the firmware update. This step
should take less than 1 minute. You can follow the progress with the status bar to the right of the Update
Sensor button. When completed, click on the Configuration tab to configure the transmitter. Remember,
when the firmware has been updated, the unit will return to its original factory settings.
If there is a communication interruption during the update, the process will stop. It is OK to click on
Update Sensor again to start the process over again.
