‘slave’ and ‘master’ mode. The Vosponder defaults to the SDI-12 slave mode. In this mode the Vosponder responds to commands issued by the datalogger over the SDI-12 bus. This is the method best used with Campbell Scientific dataloggers. OV-1... - Page 8 Vosponder Overview Several special “extended SDI-12 commands” are used to deliver data from the datalogger to the Vosponder for verbalization through the radio telemetry link. The SDI-12 master mode can be used to interface the Vosponder directly to any SDI-12-compatible sensor or other SDI-12 compatible devices. Some information about this mode is covered in Appendix A.

- Page 39 Section 5. Testing and Troubleshooting Problem: My data values are being spoken in the wrong order. Solution: Open your voice image file in the Vosponder Image Development Software, and using the UP and DOWN arrow keys to the left of the phrases, move the phrases into the order that you want them spoken.
- Page 40 Section 5. Testing and Troubleshooting Open the Ports/Flags window and watch to see if the control port that you have wired the Vosponder’s SDI-12 interface cable into ever goes high (green dot). The port must go high in order for data to be transferred to the Vosponder. If it doesn’t, then you will need to check your program and/or the datalogger’s control port to see why the control port is not working.
- Page 41 Section 5. Testing and Troubleshooting Problem: The radio doesn’t hang up after a voice message transmission. Solution: Check the radio interface cable. Make sure that the connection to the radio and the Vosponder are solid. If the problem still exists, then try replacing the cable with another one if you have a spare or can swap one out from another Vosponder that is working.
- Page 42 Section 5. Testing and Troubleshooting Be sure to use a null modem cable. Verify that Vosponder has +12 VDC on Pin 2 of connector J1 and that Pin 1 is grounded to the power supply or datalogger. Go to HyperTerminal and select File | Properties | Connect To.

Appendix C. Audio Level Controls Four audio level controls are provided on the Vosponder. The information provided here is only for a reference should a technical support representative ask you to make adjustments to the factory settings. Opening the case and adjusting these settings without first consulting with a technical support representative will VOID the warranty. - Page 48 Appendix C. Audio Level Controls at pin 6 of J6, increase the output level until peak clipping occurs then back off on R24 approximately 20% (2-3 turns). This will provide for optimum voice clarity.

Appendix E. The Anatomy of the Voice Image File The voice image file can be created using any basic word processor or text editor that is capable of saving simple .txt files. The editor must not insert any embedded control characters, visible or invisible. .RTF, .DOC, .HTM or any other format is unacceptable. - Page 52 Appendix E. The Anatomy of the Voice Image File The “Postscript” field follows. This is what is to be spoken after the data point is verbalized. Remember the characters, ~ | {} are not allowed in any text string. Another “End of Text” marker is required next. When the Vosponder encounters this marker, it checks to see if any further data points must be reported.
