Guralp Systems CMG-DCM build <10,000 - Manual (Page 184)

CMG-EAM (Platinum Firmware)
The first column shows the time-that the block was received (not the
time-stamp on the block itself) and the second column shows the
event type - “GCF block received” in most cases.
The “Details” column shows the stream ID from the received data
block and the block time-stamp. The digitiser ID is shown if it is
encoded in the block; otherwise, a best guess is displayed. The rest of
the entry shows the block type, sample rate, compression level and the
number of samples in the data block.
A hexadecimal display of the block header is shown in the final
column.
An example of an audit log display for an out-going data-stream is
shown below. This data is for the Scream network server:. The first
column now shows the time that the block was transmitted; other
details are the same as in the previous example.
