Guralp Systems Scream - Manual (Page 15)

User guide
As an example, the screen shot above shows Scream! running on a
computer which is not directly attached to any instruments. It
receives data from a single network source, MACALLAN1, which has
two serial ports Com1 and Com2. These ports are attached to the
instruments BHOLE-BH05 and GURALP-DA79 respectively: if your
installation uses a CRM (Combiner-Repeater Module) or EAM
connected to a serial port, several instruments may be listed under a
single serial port icon.
The MACALLAN1 server icon has been “unrolled” to reveal the serial
port icons. You can “roll up” icons and save space by clicking on the
box.
You can tell Scream! to ignore a particular instrument by right-clicking
on its icon and selecting Ignore. When you do this, Scream! will
discard any blocks it receives from the instrument. They will not
appear in the stream buffer or be recorded to disk. Select Ignore again
to stop ignoring the instrument.
3.3.1 Icons
Instrument icons change colour to provide you with a quick overview
of the instrument's timing and mass position status:
If both halves of the instrument icon are clear , Scream! has not
received any information from the instrument since the program
started.
If the top half is green , the instrument has reported a satisfactory
timing fix.
