6. Send the OS to the sensor with the
XLOADOS!
extended command in the following format:
<SDI-12 address>XLOADOS <baud rate> CPU:<OS name>!
NOTE:
A baud rate of 9600 is typically used. CR300-series data loggers are case sensitive, and
the file name must match the name used in the command. The All Caps checkbox on
the bottom will need to be unchecked to allow lowercase letters.
7. When the OS update is complete, the file size, bytes sent, and the word SUCCESS are
displayed. For example:
file size 117500, bytes sent 117304SUCCESS
8. Verify that the OS was updated with the verify command
aV!
, followed by the
aD0!
command to read the results.

9.1 Maintenance
The TempVue 20 SDI-12 requires minimal maintenance. Periodically check cabling for proper
connections, signs of damage, and possible moisture intrusion.
Check the radiation shield monthly to make sure it is free from dust and debris. To clean the
shield, first remove the sensor. Dismount the shield. Brush all loose dirt off. If more effort is
needed, use warm, soapy water and a soft cloth or brush to thoroughly clean the shield. Allow
the shield to dry before remounting.
Ensure the TempVue 20 SDI-12 probe is clean and free of dirt or any soiling by wiping carefully
with a lint free cloth and warm soapy water.
