MagSurvey Software Magnetometer Requirements
MagSurvey currently supports a number of magnetometer models
having a serial data stream output. In addition to those magnetometers
listed below, other models will be added from time to time -- if your unit
is not listed, contact Perception Systems, Inc. for the latest compatibility
information or to discuss the addition of other models
Please note that MagSurvey also supports certain boat-towed metal detectors,
with support for more metal detectors on the way.
Most magnetometers output data in RS-232 serial format. If your
computer has only USB inputs available, you will need to use one or two USB-to-serial
adapters (use different models, if two are used). This requires installing the adapter's driver software, and then
determining the emulated comport and baud rate from the manufacturer's
literature -- or by checking the computer's Control Panel -> System -> Hardware
Manager -> Ports (Com & LPT). It is important to install the driver
software according to the developer's instructions, and this usually involves
installing the driver before plugging-in the equipment.
- AquaScan MC5NE, MC5PES/PET, AX2000DES/DET,
Set RS232 communications to 4800 baud.
Aquascan International Ltd. may be contacted at
(+44 1633 255645) in Wales, UK.
J. W. Fishers Proton Series:
Check your owner's manual for any differences of your model from
the following: The RS232 Output Interface Option must be
installed in the magnetometer system. Communications are at
4800 baud, N,8,1. These are standard proton magnetometers that
typically output readings at 2, 3, or 4 second intervals. It
is recommended that speed-over-ground be kept to 2 knots
or less to reduce passing anomalies undetected. The company
may be contacted at www.jwfishers.com (800-822-4744) in Berkley, Massachusetts.
J. W. Fishers PULSE 10 and PULSE 12 Boat Towed Pulse
Induction Metal Detectors with RS232 Option:
Communications are at 4800 baud, N, 8, 1. These metal
detectors output peak readings at one second intervals. Do not connect the
GPS to the PULSE unit -- connect it only to the PC. Select the number of
sensors on the setup menu, and be sure to connect them in the order of Fish1,
Fish2, Fish3 -- to eliminate interfering false signals from unused inputs. MagSurvey divides the
raw readings from the PULSE by 31 to yield mag-compatible ranges. The
optional altimeter information is not relayed from the PULSE unit to the PC.
Consider setting display sensitivity to "high" and using MagSurvey's
smallest-area survey range. Company
contact information is listed above.
Gem Systems GSM-19 Series:
Of this series, the GSM-19M marine Overhauser-proton magnetometer
can be set to take readings at up to 5 per second.
Set the GSM-19 to base station mode (screen 52), magnetometer mode,
with real-time-RS232 transmission enabled. Gem Systems offers
a special spliced cable for connection to a PC and external
power. The company may be contacted at
(905-764-8008) in Ontario, Canada.
- Geometrics G-877, G-880, G-881, G882, and G-886, (also G-823 airborne):
These cesium magnetometers default to communications at 9600 baud,
N,8,1 at ten readings per second. Use the default ASCII output
format. For real-time, boat-towed operations, MagSurvey serves
as the sole PC operational software for use with these units.
The Geometrics G-880 and G-881 will initially need to have the
offset and scale factor (gain) values entered into MagSurvey Setup
in order for the depth and optional altitude readouts to display
correctly. These values are derived using the software
provided with the Geometrics units. Geometrics, Inc. may be
contacted at www.geometrics.com
(408-954-0522) in San Jose, California.
- Geometrics G-858 Series:
- For real-time, boat-mounted operations, MagSurvey serves as the
sole PC operational software for use with these units. This
cesium mag can operate at up to ten readings per second. The
Geometrics G-858 must be used in BASE STATION mode and
Real-Time-Transfer must be enabled through the System Setup Menu.
External power may optionally be applied to the unit. It is recommended that the G-858's
communications port be set to 9600 baud, N,8,1.
- Honeywell HMR2300:
These are anisotropic magneto-resistive magnetometer
modules using triple orthogonal sensors and communicating at 9600 baud.
Readout is not in nanoTesslas, so sensitivity is somewhat undefined.
Honeywell can be contacted at
www.honeywell.com/magneticsensors (800-323-8295) in Plymouth, MN.
IXSEA MAGIS and SMM-III (formerly Geomag, and
The MAGIS and SMM-III enhanced marine Overhauser-proton
magnetometers take ten readings per second. Set RS232 communications to
9600 baud, N, 8, 1. Please see www.ixsea.com, products section, for information on this international
company's magnetometer products.
- Marine Magnetics Corporation SeaSPY and
For real-time, boat-towed operations, MagSurvey serves as the sole
PC operational software for use with this unit -- once the basic
operating parameters have been set into the unit using the company's
SeaLINK or SeaNAV software. This needs to be done only once
since SeaSPY will remember these settings. This magnetometer
communicates at 9600 baud, N,8,1. Set the unit to text
mode. It is recommended that cycle time be set to 250ms.
In MagSurvey Equipment Setup for depth, set Offset = 0 and Scale Factor = 3.28
(for depth in feet), or Scale Factor = 1 (for depth in meters). Magsurvey is also capable of operating
alongside SeaNAV using separate computers (leave both of the serial
port cables' pin 3 TXD lines unconnected on the computer running
MagSurvey). Marine Magnetics Corporation may be contacted at
(905-709-3135) in Ontario, Canada.
Perception Systems TargetSpy Metal Detector
This is an interface module intended to interface most metal
detectors having audio output from a headphone jack. The product is
scheduled for release by this company in the second quarter of 2014; it uses a
USB output that emulates a serial port at 4800 baud.
Planet Electronics MX500 Digital (single towfish
Since Planet Electronics' MXSurveyII software needs to be
running on a computer with this magnetometer, using MagSurvey requires a second
computer with a single serial port connected with a splitter to the PC's RxD and
ground connections (do not connect to pin 3 -- TxD). Set the serial
port for 19200 baud, N, 8, 1, and set as a single (combined) channel.
- Quantro Sensing Discovery Series:
These magnetometers have both 5 volt serial (modified RS-232) and
RS-485 outputs. The 5V-RS-232 output will normally be used, and
it operates at 9600 baud, N,8,1. This is a standard proton
magnetometer that outputs readings at 2.5, 5, or 10 second
intervals. It will be normal for MagSurvey to indicate "Mag
Lost" between readings if the interval is set at 10
seconds. If using the 10 second setting, it is recommended that speed-over-ground be
kept to 2 knots or less to reduce passing anomalies undetected.
If your unit is equipped with a depth sensor, use Offset = 0 and Scale
Factor = 1 for depth in MagSurvey Equipment Setup. Quantro
Sensing may be contacted at www.quantrosensing.com
(321-412-1160), in central Florida.
- Quantro Sensing Data Logging Models:
This setting is for specialized Quantro Sensing magnetometers having
an attached data logger for blind recording of GPS and magnetometer data -- without a PC.
All of the data is later downloaded into a PC running MagSurvey for analysis. See the Discovery series description, above, for general setup
information, and refer to the magnetometer documentation for detailed data
logger operating instructions. Quantro
Sensing may be contacted at www.quantrosensing.com
(321-412-1160), in Florida.
- Schonstedt Instruments GAU-30:
Likely a differential flux gate magnetometer (dual-sensor
gradiometer). We know little about this magnetometer at this
time, and the unit may not be compatible with the MagSurvey
software. The RS232 communications parameters will be set
automatically by MagSurvey, except for the com port number.
- Shark Marine SDM-4000:
These are anisotropic magneto-resistive magnetometers using
triple orthogonal sensors and communicating at 9600 baud. Readout is not
in nanoTesslas, so sensitivity is somewhat undefined. Shark Marine can be
contacted at www.sharkmarine.com
(905-687-6672) in Ontario, Canada.
