320M Jr Echosounder

Overview

The lost cost, single-frequency version of the proven 320M!

The newest member of the classic KEL series of single beam echosounders, the 320M Jr is a single channel, junior brother to the dual-channel 320M and 320MP. A sophisticated, fully digital echosounder with the high-end features of more highly priced products, but in a low cost single frequency package. The 320M Jr is configured 200 kHz. It produces a high resolution record accurately depicting bottom profiles and shallow sediment layers (if configured for low frequency) with 32 shades of gray. The thermal printer uses easily loaded 21.6cm (8.5") plastic film for permanent, high-quality records. The annotated depth grid is printed with reverse shading for clarity.

Digitized water depth is shown on a large 4-digit LCD, visible in direct sunlight and backlit for night operation. Serial RS-232 depth data is continuously available in NMEA and other industry formats, and in operator-selectable time and position tagged formats.

An LCD menu display with simple 2-button control provides access to parameters such as sound velocity, draft, TX blanking, serial port assignment, time and date setting, and others, as well as a variety of self-test, communication and configuration features. All settings are retained in non-volatile memory and recalled on power-up.

Three RS-232 ports support communication with personal computers, NMEA input and output devices, GPS receivers, sound velocity sensors, heave sensors, remote depth displays and survey data loggers.

The standard 320M Jr firmware includes drivers for these devices. Field-upgradable software ensures systems remain current.
