Interface Specification Document6.3.1.51 Video Mode• DESCRIPTION:This message selects the video mode.• SYNTAX:*VMOD,N• PARAMETERS:N – Video mode.0 – NTSC.1 – PAL.2 – SVGA.• EXAMPLE:*VMOD,1This example sets the video mode to PAL.6.3.2 Time Stamp MessagesThis message is used for time stamping the bathymetric and sidescan data that is output to thenetwork. The time should be in UTC format with the following syntax. See section B.3.6.1 for adescription of the relationship of time stamps to data.• UTCMessage – $UTC,YYYYMMDD,HHMMSS.TTTTWhere:Field Description Ranges$UTC Start of MessageYYYY Years 0000 – 9999MM Month 01 – 12DD Day 01-31HH Hour 00-23MM Minute 00-59SS Second 00-59TTTT Tenths of Milliseconds 0000-99996.3.2.1 Time Synchronization of SeaBat DataThe SeaBat output message packets will always include a latency time, the time interval betweenthe sonar ping and the output of the first element of the data packet by the sonar. These latencytimes will be independently generated and entered into the packets for each type of data output:bathymetry, side scan, and snippets data.If the data collection system is using the time of receipt of the data packet to determine the sonarping time for the data packet, the latency should be subtracted from the time of receipt to determinethe ping time.If the data collection system is outputting the UTC time synchronization message to the sonar,and using the time reported within the data packet to determine the ping time associated with thedata set, the latency offset should NOT be applied to the time.______________________________________________________________________SeaBat 8101 Operator's Manual 6-21 (ISD Rev 1.23) Version 3.02
