BATS AND PORTABLE BATS OPERATION
3-46
is interfaced to a navigation system and the navigation system already interfaces to a heading sen-
sor such as a flux gate compass or gyro-compass. In this case, the Trackman’s RS-232 data does
not need to be corrected for North reference. However, Trackman requires a compass input to
compensate for vessel motion within its filtering algorithms. By selecting “Grid Only“ the target da-
ta on the Trackman screen remains referenced to North while the RS-232 data is referenced to the
bow of the vessel thus allowing both Trackman and the navigation system to function properly. To
have the Trackman Heading correction applied along with the RS-232 Data Output then select
“Both Data O/P & Grid”.
NOTE: When the Compass Correction function is set to “Grid Only”, the RS-232 data is av-
eraged (when smoothing is enabled). However, the positional data on the Trackman
display is only smoothed or averaged prior to the target’s compass correction result-
ing in positional changes directly related to the change in compass heading. When
the Compass Correction function is set to “Grid Only” the target position is averaged
after the compass has corrected the data for North Reference resulting in a more
“smoothed” target position on the Trackman screen.
Analog: For the Analog Heading Sensor electrical interface see Installation, Section 2 above. The
Transceiver converts the analog Voltage to a ship’s heading in degrees.
In the “Zero degree Voltage” box enter the minimum Voltage that corresponds to zero degrees.
(Range 0 - 5.99VDC) In the “360 degree Voltage” box enter the maximum Voltage that corre-
sponds to 359.99 degrees. (Range 0.1 - 6.0VDC)
When in analog compass mode the heading data is displayed at the top left of the screen and has a
suffix “A” attached to indicate that the data is from the analog input.
Serial: See section 2 (Installation) for wiring
the compass to the Transceiver COMMS con-
nector. Click on “Port Settings” to select the
TrackPoint (BATS) Transceiver comport that the
compass connects to. (COM2 or COM3) Set the
baud rate, Parity, Data Bits and Stop Bits to
agree with the compasses serial port protocol.
Refer to section 2 for COM Port wiring for the
COMMS connector. Select OK when done.
Format: The Input Format allows selection of either “HDT”, “HDM” or “HDG” NMEA formats. Press
OK to use the set parameters or Cancel to ignore.
