Fix Mark A single line across the chart is produced by sending HEX 06 ASCII ACK or Control F An event line will be printed across the chart at the end of the current sounding cycle and will not delay or interfere with normal operation of the unit Event Annotation When required the event line can be annotated with up to 80 characters of information This is achieved by following the HEX 06 with HEX 01 ASCII SOH or Control A Once the HEX 02 is transmitted annotation characters can be sent sequentially or with breaks between characters The ASCII string should be delimited by a HEX 04 ASCII EOT or Control D This will cause the annotation to be printed and will return the ECHOTRAC to normal operation Note Event annotation must contain at least one character before the HEX 04 delimiter even if it is only a HEX 20 space Care should also be taken to avoid annotation overrun which is caused by grouping annotated events so closely together that they obscure the record Header Information multiple line annotation This type of information would normally be hand written at the start or end of a survey line and would include information relating to date time work area etc Using the Heading Information input facility it is possible to have this information printed automatically on a blank section of chart Each line is still limited to the maximum of 80 characters but there is no limit to the number of lines of annotati
