IMAGENEX MODEL 881L DIGITAL MULTI-FREQUENCY IMAGING SONAR ROV, AUV, & UUV Offshore Oil & Gas Sunken Timber Recovery Diving Support Surveying Search & Recovery Inspection Underwater Archaeology Scientific Research Ethernet Programmable Multi-frequency High performance Lower cost Low power Simple set-up and installation Digital telemetry Full scale range from 1 m to 200 m Compact size Communication format available to user Using Ethernet communications, this all-inone, high performance digital imaging sonar can exceed 100 shots per second on the 1 m range at a 2 mm range resolution, producing near-photographic image quality. The 881L is a multi-frequency system that can operate with customized configurations or revert to default settings to match appropriate operating range scales. In addition to the benefits of low power, a simple set-up and installation procedure make this powerful sonar an ideal tool for remotely operated platforms ranging from large work ROV’s to small inspection vehicles, as well as AUV and UUV applications.

IMAGENEX TECHNOLOGY CORP. MODEL 881L ETHERNET SONAR HEAD (Multi-Frequency) WIN881L.EXE: Display Software For Win 95/98/Me/NT/2000/XP VERSION 1.04 OVERVIEW WIN881L is a Windows 95/98/Me/NT/2000/XP program that controls, displays and records data from the multi-frequency Model 881L Ethernet Sonar Head. The program communicates with the sonar head via a 10 Mbps Ethernet connection and uses an RS232 COM port at 4800,N,8,1 for receiving GPS Lat/Lng coordinates. The head can be operated at different ranges, gains, speeds, frequencies, etc. The Windows display mode must be at least 800 x 600...
