YSI Incorporated Data Scout Advanced 58
Changing the baud rate in a remote transducer is not possible with every cell phone modem. YSI has
tested the Digi Connect Remote Gateway (RG) device (with integral RealPort virtual serial port
driver) and found it capable of baud rate change. The AirLink Raven modem can only have its serial
port communications parameters set statically by AT commands. This makes it incapable of using
the configuration command shown above to change baud rate. Viewing the baud rate only shows its
local (virtual port) setting.
NOTE:
The Configure | Cal. Adjust Coeffs (HiLi Xdcr) menu item opens the following window:
Figure 4.46
The two text boxes of this window contain the current values of the Offset and Slope options, respectively, for Calibration Coefficients
that was just read from the transducer. See their ToolTips for more information. Click either text box to edit its value and then click
OK to change it.
The Configure | Main Cal. Coeffs 0-22 (HiLi Xdcr) menu item opens the following special coefficient selection window to allow the
user to select which (of 23 possible) Main Calibration coefficients to view first:
Figure 4.47
These 23 Main Calibration coefficients are the ones written permanently to the non-volatile memory of the transducers by the factory
calibration process. They can not be changed by the user, only viewed.
After selecting a particular coefficient index (0-22), a command will be sent to the transducer to read its value. Then the following
window appears to display the selected coefficient’s values.
