Communication Parameters
• COM port and baud rate settings can be modified in the upper left portion of the screen.
• Access to all communication settings (data bits, stop bits, etc.) can be set using the
Set-
tings|Port Settings
menu.
RS485 Multiple System Operation
• The top right of the screen specifies the RS485 system communication address.
• An address setting of 0 indicates RS485 is not being used. An address setting of from 1
through 15 prefaces all commands with that system address.
• See the ADVField Operation Manual for details on RS485 multi-system operation.
Basic Calibration Instructions
• Start Compass.
• Click
Connect
to establish communication.
• Click
Go
to start the compass calibration and the display of compass data.
• Follow the instructions for calibration.
o The ADVField should be rotated through at least two complete rotations, varying pitch
and roll as much as is practical (within the ±50° sensor limit).
o If possible, calibration should be performed with the ADVField installed in the mounting
frame that will be used during deployment.
• At the end of calibration, press
Stop
. Compass reports a calibration score. See the ADVField
Operation Manual for information about the calibration score.
• Compass records all compass calibration data and results to a log file. These log files are
generally used for quality assurance purposes, but are not essential to program operation (i.e.,
you can delete them). The log file name is in the format of year/month/day/ hour/minute.cmp.
For example, 0011061311.cmp stores data that was collected on November 6, 2000 at 13:11
(1:11 pm). The file can be viewed with any ASCII text editor.
