configured to operate on their own or under control from an external unit.
The altimeters incorporate a fixed crystal transducer which is matched to the range and
resolution required. The altimeter data output signals can be transmitted as both digital and
analogue signals and can communicate using RS232 or RS485 protocols.
The dual Frequency Echosounder combines the current PA200 and PA500 whist
incorporating an X-Sens MTi-3 AHRS pitch and roll sensor.
This manual covers the generic aspects of altimeters and shows the specifications for the
standard setup with the Tritech International Ltd 6 pin connector. There are a wide range of
different configurations available for Tritech altimeters so it is important to use this manual
