must change Win-Situ Software communication settings to reconnect and communicate
with the instrument.

2. Open Win-Situ Software. When it asks "Connect to device now?" click No.
3. In the top menu bar, click Preferences.
4. Click Comm Settings.
5. Enter instrument's device address into the Device Address box.*
6. Ensure the correct COM port is selected in the Port Number box. See page 33.

Mode) match the device settings.*
8. Click the check mark.
9. Click the Connect button in the lower right corner.
* If you do not know the device address or communication settings for an instrument,
disconnect the instrument from the networking device. Connect the instrument directly
to the PC. Click the Reset All Devices button in the Comm Settings window. Clicking
