When you apply a new calibration, the calibration settings are stored in two places simultaneously:
•
A microSD card inside the Control Module retains the calibration settings in flash memory.
•
The calibration settings are also stored in a local file on the PC. The file resides in a (normally hid-
den) folder: C:\ProgramData\Teledyne Oceanscience\RapidCast Interface\[Ver-
sion]\WinchCalibration.txt.
When the Control Module boots up, it checks the microSD card for the calibration settings. If the calibra-
tion settings cannot be found or if the card is inaccessible, the Interface software will automatically trans-
mit the backup calibration data that is stored on the PC, so that the winch can operate normally.
Under Current Calibration, the Calibration Source field will identify whether the calibration data is
from the Control Module’s microSD card, or whether it is from the PC (see Figure 38, page 61).
The PC Calibration File Overrides Local Winch File checkbox allows you to force the Control Mod-
ule to use the calibration data stored in the PC. This is useful if the on-board microSD card has malfunc-
tioned and may be providing incorrect data and thus needs to be overridden.
