Use the Transparent SDI-12 mode of your data recorder to issue and monitor the following SDI-12
commands
2. Check to see if you can communicate with the H-4161.
Issue a “0I!” Identify command.
The H-4161 should respond with: “012 DAAH-4161001S#000000V10<CR><LF>”
3. Check to see if the H-4161's self-test is ok.
Issue a “0V!” Verify command.
The H-4161 should respond with: 00011<CR><LF>
Issue a “0D0" command to collect the data.
The H-4161 should respond with: 0+1<CR><LF>
4. Check to see if the H-4161's 4-20mA output is working by using the “Set Milliamp” command.
Issue a “0XSM10.0!” command.
The H-4161 should respond with: I-Out=10.0<CR><LF>
This sets the H-4161s output to 10.0mA .
Check to see if the current meter you installed in Step 1 shows 10.0 mA flowing in the loop.
Experiment with different current settings using the XSMnnn command. Make certain your loop
works at the 4.0 and 20.0 mA endpoints.
Next, check to see if the H-4161 can successfully capture sensor data from your SDI-12 sensor and scale
it into 4-20mA.
5. Program the Max and Min setpoint as needed for your application, set the Monitored Address setting
as needed. In these examples the address of the sensor to be monitored is “Z”. Experiment with the
“aXSCSddd” command to make certain your Max and Min settings are correct.
6. Issue a “ZM!” measurement command to cause your SDI-12 sensor to make a measurement.
Your sensor should respond with Ztttnn<CR><LF>
where: a is the SDI-12 sensor address
ttt is a three digit integer specifying the maximum time, in seconds
the sensor will take to complete the command and have data
available in its buffer
n is a single digit integer specifying the number of values that will be
placed in the data buffer
