Tritech International Ltd Intelligent Gyro Compass
10.0 Operation
10.1 Introduction
Operation of the iGC depends mainly on its application, but in general the iGC transmits the requested
output data in the desired format, commencing this transmission immediately after power-up and
continually until the unit is switched off.
Making the best use of the output data is the user’s responsibility, but Tritech can offer valuable
assistance to ensure that the performance of the sensor is maximised.
10.2 Data Output Formats
10.2.1 Proprietary Outputs
Proprietary operating modes are selected by setting the mode switch position SW8 to the OFF
position.
The proprietary modes are mainly used in applications where the iGC is interfaced with other Tritech
iGC product family devices or directly to the iGC Navigation software.
There is also a fixed-length ASCII output proprietary mode that provides additional iGC data to
‘Industry Standard’ ASCII formats. This mode is useful where specific telegram decoding / parsing can
be implemented by the Host system.
Full details of the output data formats in Proprietary modes can be found in Appendix G.
10.2.2 Industry Standard Outputs
The iGC emulates a large number of commonly used heading sensors. In the Industry Standard
emulation modes, data telegrams are transmitted at data rates and in formats that match the original
heading sensors they are emulating.
Emulated modes are selected by setting the mode switch position SW8 into the ON position.
Full details of the output data formats in Proprietary modes can be found in Appendix H.
10.2.3 Special Modes
For special applications, a non-standard data telegram may be required to interface with existing
equipment or software. Normally data in a non-standard format can be implemented for no additional
cost – if requested at the time of purchase of the iGC. If requested after delivery, a nominal charge
may be made for providing updated firmware to support the required output.
