A4.4. Configuring the Argonaut-SL/XR for use with the AO Converter
Argonaut Operation Manual Firmware Version 7.9 (May 1, 2001)
SonTek/YSI
To configure the Argonaut SL or XR for operation with the AO Converter, use the following
command sequence. We assume you are using SonTerm to “talk” to the Converter.
1. Choose the AO type (DISABLED, CURRENT, or VOLTAGE).
AOT CURRENT (sets AO to use current-scaling)
2. Set desired data output format. Note that this entry will clear all AO channels. Do NOT
change this value after you have set the AO channels; otherwise, you will have to re-enter all
channel settings using the SAO command.
OF ENGLISH (tells Argonaut to use English measuring units)
3. Configure all the AO settings for your application.
SAO 1 VELMAG –3 3
(sets Argonaut’s AO channel 1 to send velocity magnitude to address 1 of the Converter
using minimum and maximum values of 3 ft/s)
4. Configure the Argonaut’s regular settings such as CB, CE, AI, SI, etc. (see the Argonaut
Operation Manual).
5. Save your settings.
SaveSetup
6. Start data collection.
Start
7. Verify that the Argonaut outputs the AO data string, where 2.83 is the current value in mA.
This value will vary depending on the flow conditions.
$1AO+00002.83
8. Connect the male, DB-9 RS232 connector on the AO splitter cable (Figure A4.2) to the
female, DB-9 RS232 connector on the Argonaut power and communications cable.
9. The Argonaut-AO system is now ready for data collection.
Notes:
a. If recording is enabled, the analog data will be stored on the recorder in addition to being
sent to the COM port as an analog output.
b. If AOT is set to DISABLED, the data will be sent to the serial port according to the OutFormat
setting.
c. If the OF command is sent to change the output format (English, Metric) after entering the
AO commands, this will reset all AO settings. You will then have to re-enter all AO settings
using the SAO command.
