communications
Due largely to the pervasive presence of PC based data acquisition systems aboard survey vessels, the need has
arisen for echo sounders to communicate quickly and easily in a digital format. Two of the most common
communications interface formats are RS-232C and RS-422. The COM-ports on the Echotrac CV is capable of
sending and receiving data in RS232 only. In its standard configuration, the unit sends ASCII characters at 9600
baud, (8 data bits, 1 start bit, 1 stop bit, no parity) to peripherals or data logging systems at the completion of each
sounding cycle. COM-port “Serial 1” is a bi-directional serial port with the capability of accepting input data as
well as outputting serial depth information. The following section of this chapter shows an overview of all the
output strings and their formats, followed by detailed information about the output string structures.
