Operation
You can tell Scream! to download new data automatically whenever it
receives a heartbeat message from an instrument in FILING mode. This is
useful, for example, in autonomous installations connected by intermittent
modem links. To enable this feature:
1. Choose File Setup...
→
from Scream!'s main menu, and navigate to the
Recording pane.
2. Check Auto-download on heartbeat.
3. Click OK.
Using FILING mode with Auto-download on heartbeat ensures that Scream!
receives all new data whenever it can, regardless of the configuration of any
devices between you and the instrument.
5.9.5.4 DUAL
Instructs the digitizer to transmit any continuous streams directly to clients as
for DIRECT mode, but to store triggered data into Flash storage as for FILING
mode.
If you choose DUAL mode but do not select any continuous streams for
output, the instrument will send heartbeat messages as for FILING mode.
Scream! can pick these up and download new data as necessary.
