Geometrics Inc. G-882 Cesium Marine Magnetometer Page
as it is typed and stored by the counter. When a carriage return is received by
the counter the command is executed and then echoed down the daisy chain of
counters until it is received back by the View201 program and displayed in the
data window. A correctly echoed command string is a confirmation that the
command was received and executed properly. Mis-typed or invalid commands
will be turned into an error message and echoed through to the View201
display window. (Type A1000<return> to turn the signal level channel back on).
The magnetometer data can be viewed in graphics mode by pressing the <F5>
function key. View201 defaults into displaying the magnetometer data from
counter #0 at 10 nT full scale. Data from the second and third magnetometer
can be displayed by pressing <F2> and <F3> respectively. If magnetometer 2
or 3 are not present the data fields are set to zero.
Data can be logged to disk at any time by pressing <F10>. A filename is
created based on date and time and logged to disk. A logging message is
displayed and a low frequency beeper plays to indicate that logging is taking
place. Pressing <F10> again stops the logging process.
Currently, View201 only recognizes the ASCII output format. This is the default
output format, but there is nothing preventing a change format command from
being sent to the counter module. If the output format is changed the View201
program will cease to function correctly.
A list of function keys and their use can be viewed at anytime by typing a
question mark (?).
Following is a description of each View201 function key. These are all
functions that control the operation of the View201 program and should not be
confused with commands that affect the counter module:
4.5.3.1 Function Keys
<F1> = Toggle graphics display of Mag1 on/off. Default setting is on.
This
key has effect in graphics mode only.
<F2> = Toggle graphics display of Mag2 on/off. Default setting is off. If
turned on and no magnetometer#2 is present the magnetometer 2
data value is forced to zero. This key has effect in graphics mode
only.
<F3> = Toggle graphics display of Mag3 on/off. Default setting is off. If
turned on and no magnetometer#3 is present the Mag3 data
value
is forced to zero. This key has effect in graphics mode only.
