| CMAX CM2 (Analog Out) |
| |
The CM2 Digital sidescan is made by C-Max Ltd. , of Dorset, UK. It is a recent upgrade to their previous CM800 series. It offers a digital interface for control, with the option of either analog or digital data output. The CM2 is a true digital system, with the images being digitized in the towfish. Unlike sonars that rely on analogue towfish and analogue telemetry, there is no loss of image quality in the tow cable. The top end Data Acquisition Unit was redesigned in stainless steel with an optional integrated display, retaining its PC basis. An analogue output allows for interfacing to other sonar processors. Data records can also be exported in digital form. |

The CM2 family of towfish includes two dual frequency models, types DF and EDF. These cover a total of three acoustic frequencies, namely 100kHz (LF), 325kHz (HF) and 780kHz (EF). All of the towfish models feature a digitally controlled, dynamically-optimized gain profile, automatic towfish altitude measurement and a seabed proximity alarm. All CM2 towfish are powered from the surface via the tow cable.
The standard CM2 Sonar Transceiver (STR) provides a serial (RS-232) interface for control and telemetry, plus analog connections for the sidescan data. |
