10.4 Environmental Commands

The Channel Master uses the following commands to control the environ-

mental and positional information that affects internal data processing.

>E?

Available Commands:

EC 1500 ----------------- Speed Of Sound (m/s)

ED 00000 ---------------- Xdcr Depth (deci-meters)

ES 00 ------------------- Salinity (ppt)

ET 2100 ----------------- Water Temperature (.01 deg C)

EX 01010 ---------------- Coordinate Transformations

EZ 1101101 -------------- Sensor Source {c;d;h;p;r;s;t}

E? ---------------------- Display E-Command Menu

10.4.1 Environmental Command Descriptions

This section lists the Environmental commands.

EC – Speed of Sound

Purpose Sets the speed of sound value used for Channel Master data

processing.

Format ECnnnn

Range nnnn = 1400 to 1600 meters per second

Default EC1500

Recommended Setting. The default setting for this command is

recommended for most applications.

Description EC sets the sound speed value used by the Channel Master to

scale velocity data, cell size, and range to the bottom. The

Channel Master assumes the speed of sound reading is taken

at the transducer head. See the primer for information on

speed of sound calculations.

NOTE. If the EZ Speed of Sound field = 1, the Channel Master overrides

the manually-set EC value and calculates speed of sound using the values

determined by transducer depth (ED), salinity (ES), and transducer

temperature (ET). EZ also selects the source for ED, ES, and ET.

ED – Depth of Transducer

Purpose Sets the Channel Master transducer depth.

Format EDnnnnn

Range nnnnn = 0 to 65535 decimeters (meters x 10)

Default ED00000

Recommended Setting. Use the EZ-command (set by WinHADCP).
