With each entry of an angle of tilt and angle of rotation the sensor is depicted in the bird
(fish) in the position that would be obtained if the sensor is first tilted aft from the
depicted vertical axis by the specified angle and then rotated by the specified angle about
the depicted vertical axis to its final position. Note the position of the sensor depicted in
CsAz and make the appropriate mechanical adjustments to put the sensor in this same
position as depicted by CsAz.
If you press F1 the program will identify your first available printer port and print out a
laser printer compatible graphic of the screen. F2 is for Epson compatible printers. If you
have both LPT1 and LPT2 operational and you want to go to LPT2, then add the
following to the command line:
c:\csaz.exe /L=2 or /L=3 for LPT3
9.3 View201
View201 is a DOS program that enables programming and viewing the magnetometer
and analog data from one to three CM-201 counter modules. It was written primarily as a
factory debug/test utility and is provided as a tool to help installation and testing of the
counter(s) in the field. The output can be viewed in both raw text and in graphics mode.
In addition the output data can be logged to disk if desired. The program defaults to
using Com port #1, although Com port #2 can be used be adding " /COM2" to the
command line after "View201".
Upon startup the program listens to the output data stream from the counter(s) and
synchronizes to the output baud rate. The raw output data is then displayed in a data text
window. Along the top is a status bar showing the condition of the serial port and the
serial input buffer.
View201 defaults to using COM port #1. COM port #2 can be selected by typing
"View201 /COM2" and <ENTER> at the DOS prompt.
After the magnetometer has warmed up the first comma delimited field should be
showing a stable magnetometer reading. The default counter output format includes the 4
character signal level in the next field (9999 full scale). Other data may be present as
well depending on output configuration. If more than one magnetometer is daisy chained
together there will be other magnetometer data fields embedded in the output stream.
Commands can be sent to the counter module(s) at anytime. There are many commands
that control the CM-201 which are detailed in the Section 7.2. As an example, the
command "A0000" followed by a carriage return turns off analog channel 0 (signal level)
in counter 00: Each character is sent 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
