Section 5. <strong>Argonaut</strong> Hardware<br />
5.1. <strong>Argonaut</strong> Hardware Configuration Settings<br />
<strong>SonTek</strong>/<strong>YSI</strong><br />
The hardware configuration of the different <strong>Argonaut</strong> systems depends on the requirements of the<br />
application. <strong>Argonaut</strong> hardware configuration settings can be displayed using the Show Conf<br />
command from the direct command interface (§3.14). A sample output of this command for an<br />
<strong>Argonaut</strong> SL is given below.<br />

HARDWARE CONFIGURATION PARAMETERS<br />
---------------------------------<br />
System Type -------------------- SL<br />
Sensor serial # ---------------- E15<br />
Sensor frequency - (kHz) ------- 1500<br />
Number of beams ---------------- 2<br />

Slant angle - (deg) ------------ 25.0<br />
Orientation -------------------- SIDE<br />
Compass installed ------------- NO<br />
Recorder installed ------------- YES<br />
Temperature sensor ------------- YES<br />
Pressure sensor ------------- NO<br />
Ctd sensor ------------- NO<br />
PressOffset - (dbar) ---------- 0.000000<br />
PressScale -- (dbar/count) ---- 0.000000<br />
PressScale_2 - (pdbar/count^2) - 0<br />
A brief description of each parameter is given below.<br />
• System type: Set at the factory for MD, <strong>XR</strong>, or SL.<br />
• Sensor serial number: The <strong>Argonaut</strong> serial number is stamped on the transducer head.<br />
• Sensor frequency: Specifies the acoustic frequency of the <strong>Argonaut</strong> in kHz (3000 or 1500).<br />
• Number of beams / Beam geometry / Slant angle: The <strong>Argonaut</strong> MD and <strong>XR</strong> use three<br />
beams for vertical operation. The <strong>Argonaut</strong> SL uses two beams for horizontal current<br />
measurements. The mounting angle of the <strong>Argonaut</strong> transducers is 25° for the <strong>Argonaut</strong> <strong>XR</strong><br />
and SL, 45° for the <strong>Argonaut</strong> MD. See <strong>Argonaut</strong> Principles of Operation for details on the<br />
exact beam geometry and mounting angle used by each system.<br />
• Orientation: Measurement orientation of the system for up-looking, down-looking, or sidelooking<br />
operation. Note that this setting must match the compass installation for correct<br />
operation (§4.2). Also, note that the orientation will affect the definition of the XYZ<br />
coordinate system (§6.4).<br />
• Compass / Recorder / Temperature / Pressure sensor: These settings specify which optional<br />
sensors have been installed. All systems include the recorder and temperature standard. The<br />
<strong>Argonaut</strong> MD and <strong>XR</strong> include a compass standard. The <strong>Argonaut</strong> <strong>XR</strong> includes a pressure<br />
sensor standard.<br />
• PressOffset / PressScale / PressScale_2: Factory calibration parameters for the pressure<br />
sensor (§6.6).<br />
