4.3 Configuring the Vosponder Settings
Information that you will want to have before you start setting up the
Vosponder includes:
1. What SDI-12 address do you want to assign to the Vosponder? The
default is 0. The SDI-12 address should relate to the control port on the
datalogger that you have chosen to wire the SDI-12 interface cable into.
2. What DTMF code (numeric key sequence) do you want to assign to the
Vosponder? The default is 123. Up to five numbers can be used. The
longer the number sequence the more careful you will need to be when
keying in the numbers from the radio handset. Numeric codes of two or
three numbers are recommended.
3. Will you be using the Vosponder in SDI-12 slave or master mode? The
default is slave mode. If you are using the Vosponder with a CSI
datalogger, you will want to be in slave mode.
4.3.1 Steps for Configuration and Testing the Vosponder
1. First view the current settings on the Vosponder by going to the M:>
prompt and entering the letters “V” and then “A”. This will take you to
the Vosponder View | Address screen. From here you can see what the
current settings are for SDI-12 mode, SDI-12 address, and DTMF code. If
the settings do not match what you want, then you will need to go to Step
2, otherwise you can jump to Step 3.
2. To change settings in the Vosponder from the M:> prompt enter “E” this
will take you to the Edit menu. From here make changes to the various
parameters by doing one or all of the following:
a. Change SDI-12 Address - From the E:> enter “S” to and then from
the ES> type in the new SDI-12 address (number from 0-9).
b. Change the DTMF Code – From the E:> enter “D” and then from the
ED> prompt type in the new DTMF code (one to five numbers) and
press <ENTER>
c. Change SDI-12 Mode - From the E:> enter “M” and then from the
EM> type in either “S” (Slave) or “M” (Master) to select the new
mode
3. Upload the voice image file to the Vosponder (see Section 4.2.3).
4. Check the voice image file to make sure that it transferred correctly. After
the voice image file has been transferred, from the M;> prompt enter a
“V”, from the V:> prompt enter an “I”, and then from the “VI” prompt
enter another “V” to view the voice image. Check the text string to make
sure that the text transferred to the Vosponder completely and in the
correct order. For more information about the anatomy of the voice image
file see Appendix E.
The Voice Image Development program adds some additional characters
and numbers that make the image look a little different when it is viewed
