not part of a multi-drop environment. If the sensor is part of a multi-drop network,
SmartSensor Manager can either auto-detect the multi-drop ID, or you can enter the
four-digit ID. Clicking the Use Multidrop Protocol... Connect Directly to ID: radio
button will activate the text box so you can enter the ID number.
Time Synchronization – Click the check box to have SmartSensor automatically syn-
˽
chronize with the PC clock.
Click the check box near the bottom of the Advanced Connection Settings page to use the
new settings as default. The OK button saves the new settings and the Cancel button cancels
the changes; both buttons return you to the Internet Connection page. The new settings will
be displayed in the message bar at the bottom of the page.
Firmware Upload
If the firmware installed onboard the SmartSensor is not the same as the firmware bun-
dled with the SSM software, the Firmware/Software Compatibility screen may appear after
you've finished connecting. This screen gives you four options: Upload, Exit SmartSensor
Manager, Continue w/o upload, and View Details (see Figure 4.8).

Upload
Selecting Upload will upload the bundled firmware to the sensor, thereby eliminating any
compatibility problems. The amount of time it takes to complete the upload depends pri-
marily on your connection speed, but usually varies from 1 to 10 minutes.
During the upload process, you can cancel at any time. However, if the FPGA firmware was
incompatible and the new version was not fully loaded before you clicked Cancel, the sen-
sor will revert back to a factory-installed version of the FPGA firmware upon reboot of the
sensor. The factory-installed version of the FPGA firmware may not be the same as the last
version you were running on the sensor. In this case, you will need to re-upload the version
of FPGA firmware you' d like to have on the sensor (see chapter 8 for information on how to
do this). This does not occur when you cancel an upload of DSP firmware.
If the upload completes successfully, the sensor will need to reboot and restart before the
new firmware will take effect. The restart should take about 15 seconds.
