Page 9: Introduction
ROV information such as pitch, roll, and heading are available and the head can be operated using different ranges, gains, pulse lengths, etc. Note that although the 852-GS sonar may be ordered as an RS-232 option, the echo sounder may not be interfaced via the 2-wire multi-drop system in this configuration. -

USB to RS-485 converter. The cable is then connected to either of the echo sounder ports, and the remaining echo sounder port is connected to the 852-GS scanning sonar by a 6-pin to 6-pin Impulse IE55 connector cable. -
Page 11: Sonar Without Echo Sounder Option
2.1.3. RS-232 Option While it is possible to order both the 852-GS scanning sonar and echo sounder with the RS-232 option, they cannot be used together with a multi-drop 2-wire communication system (as described above). Individual RS-232 cables will be required to communicate with each device individually and this configuration is beyond the scope of this manual. -

Page 25: Colour Table
Allows various colour combinations (background and scan) to be selected. Used to change the sonar data colour palettes for the sonar images. The 852-GS uses a colour table to represent echo data strength (amplitude). For example, the “Normal High” intensity colour table maps the echo data amplitude to 256 colours ranging from black (low strength level) through blue, green, orange, yellow, white, and red (highest strength level). -

852-GS Ultra-Miniature Imaging Sonar drift, the sonar image will be coherent, allowing the operator to continue to work. Note that the absolute heading will not be exact during this time as the sonar does not differentiate between induced drift and real movement. -
Page 29: Options => Calibrate Compass
852-GS Ultra-Miniature Imaging Sonar 3.5.7. Options => Calibrate Compass RealTime only Field calibrates the internal compass. To calibrate the compass, the sonar head must be rotated by 360° (direction is irrelevant). Check “Calibrate Compass”, rotate 360° slowly, then uncheck “Calibrate Compass” to store the settings. -
