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
‘?’.
The following is a description of each View201 function key. These are functions that
control the operation of the View201 program and should not be confused with
commands that affect the counter module:
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.

difference between Mag1 and Mag2. This key has effect in graphics mode
