852-GS Ultra-Miniature Imaging Sonar
Doc No: 430-048-0B Page 9of 34
1. INTRODUCTION
The Imagenex Model 852-GS Ultra-Miniature Imaging Sonar was designed for use with the smallest of
Remotely Operated Vehicles (ROVs) and inspection vehicles. Gyro-stabilization is integrated directly into the
sonar head, resulting in the sonar no longer being compromised by the blurring effects of host vehicle rotation.
The optional echo sounder is connected to the sonar, which, in turn, is connected to the surface. 2-Wire serial
communication is utilized (RS-485, or optionally RS-232, at 115.2 kbps). The unit will scan up to a 360° sector
with a maximum range of 50 meters. The sonar is controlled by a Windows™ based program that displays and
records data.
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.
The general features are:
Frequency
675 kHz
Transducer
Imaging type, fluid compensated
Range Resolution
10 mm (0.4") @ 500 data points or
20 mm (0.8") @ 250 data points (Polar mode)
Maximum Operating Depth
300 m
Transducer Beam Width
2.4° x 20°
Minimum Detectable Range
150 mm (6”)
Communication Interface
RS-485 serial interface @ 115.2 kbps (or RS-232 option)

2. GETTING STARTED
2.1. HARDWARE INSTALLATION
2.1.1. Sonar with Echo Sounder Option
To operate the sonar head and echo sounder, ensure the cable is connected to a PC via a 2-Wire RS-485
serial port or a 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. Connections are shown below (Figure 1 Sonar Connection):
