Terminal Emulation Programs for Communicating with the Compass Hyperterm Issues: OceanServer compasses will usually show up as an additional Hyperterm port when properly connected to a system. If the compass cannot be communicated/programmed check to confirm the Hyperterm port has the correct settings (baud is 9600, 8, 1, N (older compasses) or 19200 with firmware v1.1 or later). -

<Esc> % Change Escape Character for compass, default=27=ESC *careful* This is used to change the compasses ESCAPE character for applications where the compass may be on a shared output line and the system may send ASCII=27 characters. If you change it you will not be able to talk to the compass unless you can send the new character. - Page 17 Metals such as iron and steel will distort the magnetic field. OceanServer ships compasses with plastic standoff but users should insure that the compass has sufficient distance from ferrous objects that could bend the earth’s magnetic field and disrupt compass accuracy.

Page 19: Calibrating The Compass
(described bellow). “Soft-iron” effects should be addressed during the design in phase and compasses should be located away from such items to minimize impact to the sensor. OceanServer compasses with firmware version V1.4 and later include a soft iron calibration option. - Page 20 Users will need to calibrate the compass. Step 1: Select appropriate location and install OceanServer Compass in device IMPORTANT NOTE: Compasses require users to hit the < Esc > key prior to each programming/calibration step. This has been added to prevent accidental programming.
- Page 21 (i.e. Hit space and start at step 3 above). Compasses can also be calibrated in the latest version of the OceanServer Windows Demo program. The basic steps are the same as described above. The feature can be found under the...
- Page 22 Optional Soft Iron Calibration The above mentioned (C,Z) calibration routines do not compensate for soft iron effects. Soft iron, batteries, wires with moving currents and other high permeability materials in the near field cause these. These are generally far weaker than hard iron effects.
- Page 23 After you run through the calibration process, you will see the correction values generated by the process. At this point, the soft iron calibration is completed. You should go back and check the cardinal points with your system. You should see your system more inline with the cardinal points.
- Page 24 (2) Averaging of readings, n Sample in the average This will be a moving average filter of the magnetic readings and the accelerometer readings. A value of 1 sample is no filtering, the default is 6 with an output rate of 10 samples per second. The output rate of samples per second combines with the number of samples in the average to give you the lag in response time of the output.

Our demo program runs on Windows only but on all other operating systems you can open a terminal program to the virtual serial port and talk/listen to the compass with it's NMEA strings. If you would like a method to test the OS5000-T (TTL only) with a RS232 com port on a PC, Black Box Networks offers a RS232 to TTL converter (PN# IC1157A). -
