Section 4. Vosponder Configuration
and Programming
1. Hardware connections to the datalogger and radio (Section 1)
2. Programming the datalogger to output the data values to the
Vosponder (Section 2)
3. Developing a voice image file for the Vosponder (Section 3)
► 4. Setup and testing of the Vosponder (Section 4)
4.1 Communicating with the Vosponder
The final step is to configure the Vosponder and upload the voice image file
that you created in Section 3. Connect the Vosponder to a computer using a
null modem cable. (See Section 1, Figure 1-3.) The computer will need to be
running a terminal program such as HyperTerminal® or Procom®. The
Vosponder will also need to be powered. If you have the Vosponder connected
to the datalogger with the SDI-12 cable and the datalogger’s power supply is
on, then the Vosponder will have power. Otherwise, you will need to run a
12 VDC power connection to +12 V and GND inputs on the Vosponder’s
SDI-12 terminal.
Open HyperTerminal or your terminal program and set up a new file. The
terminal communications settings must to be set as follows:
Baud Rate 2400
Data Bits 8
Parity None
Stop Bit 1
Flow Control Xon / Xoff
ASCII Line Delay 15 milliseconds or greater
ASCII Character Delay 20 milliseconds or greater
