6.7 Description of the binary <strong>for</strong>mat<br />
The binary <strong>for</strong>mat stored in the memory of the <strong>STEPP</strong> device has the following<br />
structure.<br />
Name Format Checksum End Sequence<br />
$GPLOG , <br />
$GPLOG,19590B9E336B822E685F2C6264030010421500200025,195910DE33BBC<br />

A record line in the binary <strong>for</strong>mat consists of two data records - the <br />
and fields, similar regarding the build structure, with a maximum<br />
data compression. Data records and are comma delimited<br />
“,”. This <strong>for</strong>mat can be applied when a large amount of recorded data in a short<br />
time is required to be downloaded from the <strong>STEPP</strong> device remotely via a data<br />
call connection.<br />
The following table is intended as a quick reference to explain the stored<br />
binary data.<br />
